RISK FACTORS

 

You should consider carefully the following information about the risks described below, together with the other information contained in this prospectus and in our other public filings in evaluating our business. If any of the following risks actually occurs, our business, financial condition, results of operations and future growth prospects would likely be materially and adversely affected. In these circumstances, the market price of our common stock would likely decline.

 

Risks Related to Our Business

 

We expect our net losses to continue for at least several years and are unable to predict the extent of future losses or when we will become profitable, if ever.

 

We have experienced significant net losses since our inception. As of December 31, 2004, we had an accumulated deficit of approximately $94.3 million. We expect our annual net losses to increase over the next several years as we expand our research and development activities, incur significant preclinical and clinical development costs, and enhance our infrastructure.

 

We have not received, and do not expect to receive for at least the next several years, any revenues from the commercialization of our drug candidates. Our primary source of revenues for the year ended December 31, 2004 was from research and milestone payments under our collaboration agreements with Allergan. For the year ended December 31, 2004, we received 98 percent of our revenues from our collaborations with Allergan. We anticipate that collaborations with pharmaceutical companies will continue to be our primary source of revenues for the next several years, which provide us with research funding and potential milestone payments and royalties. We cannot be certain that the milestones required to trigger payments will be reached or that we will secure additional collaboration agreements. To obtain revenues from our drug candidates, we must succeed, either alone or with others, in developing, obtaining regulatory approval for, and manufacturing and marketing drugs with significant market potential. We may never succeed in these activities, and may never generate revenues that are significant enough to achieve profitability.

 

Our most advanced clinical products are in clinical trials, which are long, expensive and unpredictable, and there is a high risk of failure.

 

Preclinical testing and clinical trials are long, expensive and unpredictable processes that can be subject to delays. It may take several years to complete the preclinical testing and clinical development necessary to commercialize a drug, and delays or failure can occur at any stage. Interim results of clinical trials do not necessarily predict final results, and success in preclinical testing and early clinical trials does not ensure that later clinical trials will be successful. A number of companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in advanced clinical trials even after promising results in earlier trials.

 

All of our drug candidates are at an early stage of development and the historical rate of failures for drug candidates is extremely high. Our three Phase II-stage clinical programs are ACP-103 for treatment-induced dysfunctions in Parkinson’s disease, ACP-103 as an adjunctive therapy for schizophrenia, and ACP-104 for the treatment of schizophrenia.

 

In connection with clinical trials, we face risks that:

 

    a drug candidate may not prove to be efficacious;

 

    patients may die or suffer other adverse effects for reasons that may or may not be related to the drug candidate being tested;

 

    the results may not confirm the positive results of earlier trials; and

 

    the results may not meet the level of statistical significance required by the Food and Drug Administration, or FDA, or other regulatory agencies.

Table of Contents

If we do not successfully complete preclinical and clinical development, we will be unable to market and sell products derived from our drug candidates and to generate product revenues. Even if we do successfully complete Phase I and Phase II clinical trials, those results are not necessarily predictive of results of future trials. Of the large number of drugs in development, only a small percentage result in the submission of a new drug application to the FDA and even fewer are approved for commercialization.

 

Delays, suspensions and terminations in our clinical trials could result in increased costs to us and delay our ability to generate product revenues.

 

The commencement of clinical trials can be delayed for a variety of reasons, including delays in:

 

    demonstrating sufficient safety and efficacy to obtain regulatory approval to commence a clinical trial;

 

    reaching agreement on acceptable terms with prospective contract research organizations and clinical trial sites;

 

    manufacturing sufficient quantities of a drug candidate;

 

    obtaining approval of an Investigational New Drug Application, or IND, from the FDA;

 

    obtaining institutional review board approval to conduct a clinical trial at a prospective site; and

 

    insufficient patient enrollment, which is a function of many factors, including the size of the patient population, the nature of the protocol, the proximity of patients to clinical sites, the availability of effective treatments for the relevant disease and the eligibility criteria for the clinical trial.

 

Once a clinical trial has begun, it may be delayed, suspended or terminated due to a number of factors, including:

 

    ongoing discussions with regulatory authorities regarding the scope or design of our clinical trials or requests by them for supplemental information with respect to our clinical trial results;

 

    failure to conduct clinical trials in accordance with regulatory requirements;

 

    lower than anticipated retention rate of patients in clinical trials;

 

    serious adverse events or side effects experienced by participants; and

 

    insufficient supply or deficient quality of drug candidates or other materials necessary for the conduct of our clinical trials.

 

Many of these factors may also ultimately lead to denial of regulatory approval of a current or potential drug candidate. If we experience delays in our clinical trials, the commercial prospects for our drug candidates will be harmed, and our ability to generate product revenues will be delayed.

 

If we fail to obtain the capital necessary to fund our operations, we will be unable to successfully develop products.

 

We have consumed substantial amounts of capital since our inception. For the year ended December 31, 2004, we used $20.7 million in cash, cash equivalents and investment securities to fund our operating activities. Although we believe our existing cash resources and anticipated payments from existing agreements with our collaborators will be sufficient to fund our anticipated cash requirements through at least mid-2007, we will require significant additional financing in the future to continue to fund our operations. Our future capital requirements will depend on, and could increase significantly as a result of, many factors, including:

 

    progress in, and the costs of, our preclinical studies and clinical trials and other research and development programs;

 

    the scope, prioritization and number of our research and development programs;

 

2


Table of Contents
    the ability of our collaborators and us to reach the milestones, and other events or developments, triggering payments under our collaboration agreements or to otherwise make payments under these agreements;

 

    the costs involved in filing, prosecuting, enforcing and defending patent claims and other intellectual property rights;

 

    the costs of securing manufacturing arrangements for clinical or commercial production; and

 

    the costs of establishing or contracting for sales and marketing capabilities if we obtain regulatory clearances to market our drug candidates.

 

Until we can generate significant continuing revenues, we expect to satisfy our future cash needs through strategic collaborations, private or public sales of our securities, debt financings, or by licensing all or a portion of our drug candidates or technology. We cannot be certain that additional funding will be available to us on acceptable terms, if at all. If funds are not available, we may be required to delay, reduce the scope of, or eliminate one or more of our research or development programs or our commercialization efforts. Additional funding may significantly dilute existing stockholders.

 

We depend on collaborations with third parties to develop and commercialize selected drug candidates and to provide the majority of our revenues.

 

A key aspect of our strategy is to selectively enter into collaborations with third parties. We currently rely, and will continue to rely, on our collaborators for financial resources and for development, commercialization and regulatory expertise for selected drug candidates. For the year ended December 31, 2004, we received 98 percent of our revenues from our collaborations with Allergan. We expect that nearly all of our revenues for the foreseeable future will be generated by collaborations, although there is no guarantee that revenues from our collaborations will continue at current or past levels.

 

Our collaborators may fail to develop or effectively commercialize products using our drug candidates or technologies because they:

 

    do not have sufficient resources or decide not to devote the necessary resources due to internal constraints such as limited cash or human resources;

 

    decide to pursue a competitive product developed outside of the collaboration; or

 

    cannot obtain the necessary regulatory approvals.

 

The continuation of our collaborations is dependent on our collaborators’ periodic renewal of the governing agreements. Allergan and Sepracor can terminate our existing collaborations before the full term of these collaborations under specific circumstances, including in some cases the right to terminate upon notice. We may not be able to renew these collaborations on acceptable terms, if at all. We also face competition in our search for new collaborators.

 

If conflicts arise with our collaborators, they may act in their self interests, which may be adverse to our interests.

 

Conflicts may arise in our collaborations due to one or more of the following:

 

    disputes with respect to payments that we believe are due under the applicable agreements;

 

    disagreements with respect to ownership of intellectual property rights;

 

    unwillingness on the part of a collaborator to keep us informed regarding the progress of its development and commercialization activities, or to permit public disclosure of these activities;

 

    delay of a collaborator’s development or commercialization efforts with respect to our drug candidates; or

 

    termination or non-renewal of the collaboration.

Table of Contents

Conflicts arising with our collaborators could harm our reputation, result in a loss of revenues, reduce our cash position and cause a decline in our stock price.

 

In addition, in each of our collaborations, we generally have agreed not to conduct independently, or with any third party, any research that is directly competitive with the research conducted under our collaborations. Our collaborations may have the effect of limiting the areas of research that we may pursue, either alone or with others. Our collaborators, however, may develop, either alone or with others, products in related fields that are competitive with the products or potential products that are the subject of these collaborations.

 

We have collaborations with Allergan for the development of drug candidates related to neuropathic pain and opthalmic diseases, including glaucoma. Allergan currently markets therapeutic products to treat glaucoma and is engaged in other research programs related to glaucoma and other ophthalmic products that are independent from our development program in this therapeutic area. Allergan is also pursuing other research programs related to pain management that are independent from our collaboration in this therapeutic area. Our collaboration with Sepracor includes an option to pursue a combination drug to treat sleep disorders. Sepracor currently markets a therapeutic product to treat sleep disorders and is engaged in other research programs related to this field that are independent from our development program in this therapeutic area. Competing products, either developed by our collaborators or to which our collaborators have rights, may result in the allocation of resources to competing products and their withdrawal of support for our drug candidates.

 

We rely on third parties to coordinate our clinical trials and perform data collection and analysis, which may result in costs and delays that prevent us from successfully commercializing drug candidates.

 

Although we design and manage our current preclinical studies and clinical trials, we currently do not have the ability to coordinate clinical trials for our drug candidates. In addition to our collaborators, we rely on contract research organizations, medical institutions, clinical investigators and contract laboratories to perform data collection and analysis and other aspects of our clinical trials. In addition, we also rely on third parties to assist with our preclinical studies, including studies regarding biological activity, safety, absorption, metabolism and excretion of drug candidates.

 

Our preclinical development activities or clinical trials may be delayed, suspended or terminated if:

 

    these third parties do not successfully carry out their contractual duties or fail to meet regulatory obligations or expected deadlines;

 

    these third parties need to be replaced; or

 

    the quality or accuracy of the data obtained by third parties is compromised due to their failure to adhere to our clinical protocols or regulatory requirements or for other reasons.

 

Failure to perform by these third parties may increase our development costs, delay our ability to obtain regulatory approval and prevent the commercialization of our drug candidates. We currently use several contract research organizations to perform services for our preclinical studies and clinical trials. While we believe that there are numerous alternative sources to provide these services, in the event that we seek such alternative sources, we may not be able to enter into replacement arrangements without delays or additional expenditures.

 

Even if we successfully complete the clinical trials of our drug candidates, they may fail for other reasons.

 

Even if we successfully complete the clinical trials of our drug candidates, they may fail for other reasons, including the possibility that the drug candidates will:

 

    fail to receive the regulatory clearances required to market them as drugs;

 

    be subject to proprietary rights held by others requiring the negotiation of a license agreement prior to marketing;

 

4


Table of Contents
    be difficult or expensive to manufacture on a commercial scale;

 

    have adverse side effects that make their use less desirable; or

 

    fail to compete with drug candidates or other treatments commercialized by our competitors.

 

Our drug candidates may not gain acceptance among physicians, patients and the medical community, thereby limiting our potential to generate revenues.

 

Even if our drug candidates are approved for commercial sale by the FDA or other regulatory authorities, the degree of market acceptance of any approved drug candidate by physicians, healthcare professionals and third-party payors and our profitability and growth will depend on a number of factors, including:

 

    our ability to provide acceptable evidence of safety and efficacy;

 

    relative convenience and ease of administration;

 

    the prevalence and severity of any adverse side effects;

 

    availability of alternative treatments;

 

    pricing and cost effectiveness, which may be subject to regulatory control;

 

    effectiveness of our or our collaborators’ sales and marketing strategy; and

 

    our ability to obtain sufficient third-party insurance coverage or reimbursement.

 

If any drug candidate that we discover and develop does not provide a treatment regimen that is as beneficial as the current standard of care or otherwise does not provide patient benefit, that product will not achieve market acceptance and we will not generate sufficient revenues to achieve or maintain profitability.

 

We do not know whether one of our drug candidates, ACP-104, will have the same adverse effects as clozapine, a currently available therapy.

 

One of our drug candidates under development is ACP-104 for the treatment of schizophrenia. ACP-104 is formed in the body from clozapine, a generic drug that is currently approved as a “second-line” therapy for schizophrenia in the United States. This means that clozapine will only be prescribed to a patient after a doctor determines that the patient has failed to progress under a “first-line” therapy consisting of antipsychotic drugs. Clozapine is associated with the occurrence of a rare and potentially fatal blood disorder leading to a complete loss of white blood cells, known as agranulocytosis, in approximately one percent of patients treated with clozapine. As a result, patients being treated with clozapine are subject to weekly or bi-weekly blood monitoring. In addition, one of the other side effects of clozapine is the occurrence of seizures, which is found in approximately five percent of users. ACP-104 may have the same adverse effects of clozapine or other significant adverse effects and, if successfully developed, may also only be approved as a “second-line” therapy. These factors could substantially limit the commercial potential of ACP-104 and may substantially restrict its potential market.

 

If we are unable to attract, retain and motivate key management and scientific staff, our drug development programs and our research and discovery efforts may be delayed and we may be unable to successfully develop or commercialize our drug candidates.

 

Our success depends on our ability to attract, retain and motivate highly qualified management and scientific personnel. In particular, our drug discovery and development programs depend on our ability to attract and retain highly skilled chemists, biologists, pharmacologists and development personnel, especially in the fields of central nervous system disorders, including neuropsychiatric and pain disorders. In addition, we will need to hire additional personnel as we continue to expand our clinical development and other research and development activities. We face competition for experienced scientists and other technical personnel from

 

5


Table of Contents

numerous companies and academic and other research institutions. Competition for qualified personnel is particularly intense in the San Diego, California area. If we are unable to attract and retain the necessary personnel, this will significantly impede the achievement of our research and development objectives and our ability to meet the demands of our collaborators in a timely fashion.

 

Although we have employment agreements with key members of management, all of our employees are “at will” employees, which means that any employee may quit at any time and we may terminate any employee at any time. We do not carry “key person” insurance covering members of senior management.

 

We do not know whether our drug discovery platform will lead to the discovery or development of commercially viable drug candidates.

 

Our drug discovery platform uses new and unproven methods to identify and develop drug candidates. We have never successfully completed clinical development of any of our drug candidates, and there are no drugs on the market that have been discovered using our drug discovery platform.

 

Much of our research focuses on small molecule drugs for the treatment of central nervous system disorders. Due to our limited resources, we may have to forego potential opportunities with respect to discovering drug candidates to treat diseases or conditions in other areas. If we are not able to use our technologies to discover and develop drug candidates that can be commercialized, we may not achieve profitability. In the future, we may find it necessary to license the technology of others or acquire additional drug candidates to augment the results of our internal discovery activities. If we are unable to identify new drug candidates using our drug discovery platform, we may be unable to establish or maintain a clinical development pipeline or generate product revenues.

 

We may not be able to continue or fully exploit our collaborations with outside scientific and clinical advisors, which could impair the progress of our clinical trials and our research and development efforts.

 

We work with scientific and clinical advisors at academic and other institutions who are experts in the field of central nervous system disorders. They assist us in our research and development efforts and advise us with respect to our clinical trials. These advisors are not our employees and may have other commitments that would limit their future availability to us. Although our scientific and clinical advisors and collaborators generally agree not to engage in competing work, if a conflict of interest arises between their work for us and their work for another entity, we may lose their services, which may impair our reputation in the industry and delay the clinical development of our drug candidates.

 

We will need to increase the size of our organization, and we may encounter difficulties managing our growth, which could adversely affect our results of operations.

 

We will need to expand and effectively manage our operations and facilities in order to advance our drug development programs, achieve milestones under our collaboration agreements, facilitate additional collaborations and pursue other development activities. It is possible that our human resources and infrastructure may be inadequate to support our future growth. To manage our growth, we will be required to continue to improve our operational, financial and management controls, reporting systems and procedures in at least two countries and to attract and retain sufficient numbers of talented employees. In addition, we may have to develop sales, marketing and distribution capabilities if we decide to market any drug that we may successfully develop without partnering with third parties. We may not successfully manage the expansion of our operations and, accordingly, may not achieve our research, development and commercialization goals.

 

We face financial and administrative challenges in coordinating the operations of our European activities with our activities in California, which could have on adverse impact on our operations.

 

Our subsidiary in Denmark, ACADIA Pharmaceuticals A/S, employs approximately 33 percent of our total personnel and is engaged in research and development activities, with primary responsibility for combinatorial,

Table of Contents

medicinal and analytical chemistry. Our principal executive offices, however, are located in San Diego. The additional administrative expense required to follow and coordinate activities in both Europe and California could divert management resources from other important endeavors and, in turn, delay any development and commercialization efforts. In addition, currency fluctuations involving our Danish operations may cause foreign currency translation gains and losses. These exchange-rate fluctuations could have a negative effect on our operations. We do not engage in currency hedging transactions.

 

We face financial and administrative challenges in opening our new chemistry research facility in Malmo, Sweden, which could have on adverse impact on our operations.

 

We have announced that we have entered into a lease for a chemistry research and development facility in Malmo, which is located near our current facilities in the Copenhagen region. We will incur additional costs in setting up and adjusting to operations in a new country with a new Swedish subsidiary. In addition, we may not be able to retain all of our current European employees when we establish our new facility in Malmo. In addition, like our current Danish operations, currency fluctuations involving our Swedish operations may cause foreign currency translation gains and losses. These exchange-rate fluctuations could have a negative effect on our operations. As mentioned above, we do not engage in currency hedging transactions.

 

We expect that our results of operations will fluctuate, which may make it difficult to predict our future performance from period to period.

 

Our quarterly operating results have fluctuated in the past and are likely to do so in the future. Some of the factors that could cause our operating results to fluctuate from period to period include:

 

    the status of development of ACP-103 and ACP-104 and the preclinical and clinical development of our other drug candidates;

 

    whether we generate revenues by achieving specified research or commercialization milestones under any agreements or otherwise receive potential payments under these agreements;

 

    the incurrence of preclinical or clinical expenses that could fluctuate significantly from period to period;

 

    the initiation, termination or reduction in the scope of our collaborations during these periods or any disputes regarding these collaborations;

 

    the timing of our satisfaction of applicable regulatory requirements;

 

    the rate of expansion of our clinical development and other internal research and development efforts;

 

    the effect of competing technologies and products and market developments; and

 

    general and industry specific economic conditions.

 

We believe that quarterly comparisons of our financial results are not necessarily meaningful and should not be relied upon as an indication of our future performance.

 

Relying on third-party manufacturers may result in delays in our clinical trials and product introductions.

 

We have no manufacturing facilities and have no experience in the manufacturing of drugs or in designing drug-manufacturing processes. We have contracted with third-party manufacturers to produce, in collaboration with us, our drug candidates for clinical trials. If any of our drug candidates are approved by the FDA or other regulatory agencies for commercial sale, we may need to contract with a third party to manufacture them in larger quantities. We currently use third-party manufacturers to produce ACP-103 and ACP-104 for us. While we believe that there are alternative sources available to manufacture our drug candidates, in the event that we seek such alternative sources, we may not be able to enter into replacement arrangements without delays or additional expenditures. We cannot estimate these delays or costs with certainty but do not expect them to be material.

Table of Contents

Our manufacturers are obliged to operate in accordance with FDA-mandated current good manufacturing practices, or cGMPs. A failure of any of our contract manufacturers to establish and follow cGMPs and to document their adherence to such practices may lead to significant delays in clinical trials or obtaining regulatory approval of drug candidates or the ultimate launch of our products into the market. Failure by our third-party manufacturers or us to comply with applicable regulations could result in sanctions being imposed on us, including fines, injunctions, civil penalties, failure of the government to grant premarket approval of drugs, delays, suspension or withdrawal of approvals, seizures or recalls of products, operating restrictions and criminal prosecutions.

 

Our management has broad discretion over the use of our cash and we may not use our cash effectively, which could adversely affect our results of operations.

 

Our management has significant flexibility in applying our cash resources and could use these resources for corporate purposes that do not increase our profitability or our market value, or in ways with which our stockholders may not agree. We may use our cash resources for corporate purposes that do not yield a significant return or any return at all for our stockholders, which may cause our stock price to decline.

 

We will incur increased costs as a result of recently enacted and proposed changes in laws and regulations relating to corporate governance and other matters.

 

Recently enacted and proposed changes in the laws and regulations affecting public companies, including the provisions of the Sarbanes-Oxley Act of 2002, or SOA, and rules adopted or proposed by the SEC and by the Nasdaq Stock Market, will result in increased costs to us as we evaluate the implications of any new rules and respond to their requirements. Although we are not required to issue an evaluation of our internal control over financial reporting under Section 404 of SOA until March 2006, at the earliest, preparations for the issuance of this report have already resulted in increased costs to us, which will increase further. If we are not able to issue an evaluation of our internal control over financial reporting as required or we or our independent registered public accouting firm determine that our internal control over financial reporting is not effective, this shortcoming could have an adverse effect on our business and financial results and the price of our common stock could be negatively affected. The new rules could make it more difficult or more costly for us to obtain certain types of insurance, including director and officer liability insurance, and we may be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. The impact of these events could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees and as executive officers. We cannot predict or estimate the amount of the additional costs we may incur or the timing of such costs to comply with these rules and regulations.

 

Changes in stock option accounting treatment may adversely affect our results of operations.

 

Changes in stock option accounting treatment commencing January 1, 2006 will require us to account for employee stock options as compensation expense in our financial statements. In December 2004, the Financial Accounting Standards Board, or FASB, issued SFAS No. 123 (revised 2004), Share-Based Payment, or SFAS 123(R), which requires that compensation costs relating to share-based payment transactions be recognized in financial statements. We are required to implement SFAS 123(R) in our first quarter of 2006. We are currently evaluating the requirements of SFAS 123(R) and we have not yet fully determined the impact on our consolidated financial statements. However, implementation of SFAS 123(R) could materially and adversely affect our reported results of operations and our timing to achieve profitability.

 

If we are unable to establish sales and marketing capabilities or enter into agreements with third parties to sell and market any products we may develop, we may not be able to generate product revenue.

 

We do not currently have an organization for the sales, marketing and distribution of pharmaceutical products. In order to market any products that may be approved by the FDA, we must build our sales, marketing, managerial and other non-technical capabilities or make arrangements with third parties to perform these

services. If we are unable to establish adequate sales, marketing and distribution capabilities, whether independently or with third parties, we may not be able to generate product revenue and may not become profitable.

 

If we engage in any acquisition, we will incur a variety of costs and may never realize the anticipated benefits of the acquisition.

 

We may attempt to acquire businesses, technologies, services or products or license in technologies that we believe are a strategic fit with our business. We have limited experience in identifying acquisition targets, successfully completing proposed acquisitions and integrating any acquired businesses, technologies, services or products into our current infrastructure. The process of integrating any acquired business, technology, service or product may result in unforeseen operating difficulties and expenditures and may divert significant management attention from our ongoing business operations. As a result, we will incur a variety of costs in connection with an acquisition and may never realize its anticipated benefits.

 

Earthquake damage to our facilities could delay our research and development efforts and adversely affect our business.

 

Our headquarters and research and development facilities in San Diego are located in a seismic zone, and there is the possibility of an earthquake, which could be disruptive to our operations and result in delays in our research and development efforts. In the event of an earthquake, if our facilities or the equipment in our facilities is significantly damaged or destroyed for any reason, we may not be able to rebuild or relocate our facilities or replace any damaged equipment in a timely manner and our business, financial condition and results of operations could be materially and adversely affected. We do not have insurance for damages resulting from earthquakes.

 

Risks Related to Our Intellectual Property

 

Our ability to compete may decline if we do not adequately protect our proprietary rights.

 

Our commercial success depends on obtaining and maintaining proprietary rights to our drug candidates and technologies and their uses, as well as successfully defending these rights against third-party challenges. We will only be able to protect our drug candidates, proprietary technologies and their uses from unauthorized use by third parties to the extent that valid and enforceable patents or effectively protected trade secrets cover them. Although we have filed several patent applications with respect to ACP-104 and ACP-103, we have not been issued any patents with respect to ACP-104, and have been issued only two patents with respect to ACP-103.

 

Our ability to obtain patent protection for our products and technologies is uncertain due to a number of factors, including:

 

    we may not have been the first to make the inventions covered by our pending patent applications or issued patents;

 

    we may not have been the first to file patent applications for our drug candidates or the technologies we rely upon;

 

    others may independently develop similar or alternative technologies or duplicate any of our technologies;

 

    our disclosures in patent applications may not be sufficient to meet the statutory requirements for patentability;

 

    any or all of our pending patent applications may not result in issued patents;

 

    we may not seek or obtain patent protection in all countries that will eventually provide a significant business opportunity;

 

9


Table of Contents
    any patents issued to us or our collaborators may not provide a basis for commercially viable products, may not provide us with any competitive advantages or may be challenged by third parties;

 

    our proprietary technologies may not be patentable;

 

    others may design around our patent claims to produce competitive products which fall outside of the scope of our patents; or

 

    others may identify prior art which could invalidate our patents.

 

Even if we have or obtain patents covering our drug candidates or technologies, we may still be barred from making, using and selling our drug candidates or technologies because of the patent rights of others. Others have or may have filed, and in the future are likely to file, patent applications covering compounds, assays, genes, gene products or therapeutic products that are similar or identical to ours. There are many issued U.S. and foreign patents relating to genes, nucleic acids, polypeptides, chemical compounds or therapeutic products, and some of these may encompass reagents utilized in the identification of candidate drug compounds or compounds that we desire to commercialize. Numerous U.S. and foreign issued patents and pending patent applications owned by others exist in the area of central nervous system disorders and the other fields in which we are developing products. These could materially affect our ability to develop our drug candidates or sell our products. Because patent applications can take many years to issue, there may be currently pending applications, unknown to us, that may later result in issued patents that our drug candidates or technologies may infringe. These patent applications may have priority over patent applications filed by us.

 

We regularly conduct searches to identify patents or patent applications that may prevent us from obtaining patent protection for our proprietary compounds or that could limit the rights we have claimed in our patents and patent applications. In particular, we are aware of claims that have been allowed by, and are pending before, the United States Patent and Trademark Office that, if issued as currently drafted, would encompass the chemical structure of ACP-103. While we do not believe that these pending claims would be valid if issued in their current form, there can be no assurance that a court would find these claims invalid or that the text or substance of these claims will not be modified upon further prosecution of the application. If valid, these claims could limit our rights with respect to ACP-103.

 

Disputes may arise regarding the ownership or inventorship of our inventions. It is difficult to determine how such disputes would be resolved. Others may challenge the validity of our patents. If our patents are found to be invalid, we will lose the ability to exclude others from making, using or selling the inventions claimed therein.

 

Some of our academic institutional licensors, research collaborators and scientific advisors have rights to publish data and information to which we have rights. If we cannot maintain the confidentiality of our technology and other confidential information in connection with our collaborations, then our ability to receive patent protection or protect our proprietary information will be impaired. In addition, technology that we may license in may become important to some aspects of our business. We generally will not control the patent prosecution, maintenance or enforcement of in-licensed technology.

 

We have limited proprietary rights to one of our drug candidates, ACP-104, which may limit our ability to prevent competitors from exploiting that compound.

 

One of our drug candidates, ACP-104, is a publicly available compound, and we will have limited proprietary rights in this candidate. Other companies may obtain patents or regulatory approvals to use the same drug for treatments other than to treat the indications for which we have filed for patent protection. We are aware of an issued patent not owned by us that claims the use of N-desmethylclozapine, which is the chemical name for ACP-104, to induce analgesia. ACP-104, which we are developing for treatment of schizophrenia, is formed in the body from clozapine and its structure was known prior to our filing of patent applications relating to its use to treat certain conditions. Accordingly, we will not be able to obtain composition of matter patents for ACP-104. We have filed a method of use patent application for ACP-104, but a competitor could use ACP-104, and patent

 

10


Table of Contents

its method of use, for a treatment not covered by our patent application. In addition, while we have filed a patent application directed to methods of synthesis of ACP-104, those claims will not prevent a potential competitor from making ACP-104.

 

Confidentiality agreements with employees and others may not adequately prevent disclosure of our trade secrets and other proprietary information and may not adequately protect our intellectual property, which could limit our ability to compete.

 

Because we operate in the highly technical field of drug discovery and development of small molecule drugs, we rely in part on trade secret protection in order to protect our proprietary technology and processes. However, trade secrets are difficult to protect. We enter into confidentiality and intellectual property assignment agreements with our corporate partners, employees, consultants, outside scientific collaborators, sponsored researchers and other advisors. These agreements generally require that the other party keep confidential and not disclose to third parties all confidential information developed by the party or made known to the party by us during the course of the party’s relationship with us. These agreements also generally provide that inventions conceived by the party in the course of rendering services to us will be our exclusive property. However, these agreements may not be honored and may not effectively assign intellectual property rights to us. Enforcing a claim that a party illegally obtained and is using our trade secrets is difficult, expensive and time consuming and the outcome is unpredictable. In addition, courts outside the United States may be less willing to protect trade secrets. The failure to obtain or maintain trade secret protection could adversely affect our competitive position. In addition, we have not entered into any noncompete agreements with any of our employees other than Dr. Brann.

 

A dispute concerning the infringement or misappropriation of our proprietary rights or the proprietary rights of others could be time consuming and costly, and an unfavorable outcome could harm our business.

 

There is significant litigation in our industry regarding patent and other intellectual property rights. While we are not currently subject to any pending intellectual property litigation, and are not aware of any such threatened litigation, we may be exposed to future litigation by third parties based on claims that our drug candidates, technologies or activities infringe the intellectual property rights of others. In particular, there are many patents relating to specific genes, nucleic acids, polypeptides or the uses thereof to identify drug candidates. Some of these may encompass genes or polypeptides that we utilize in our drug development activities. If our drug development activities are found to infringe any such patents, we may have to pay significant damages or seek licenses to such patents. A patentee could prevent us from using the patented genes or polypeptides for the identification or development of drug compounds. There are also many patents relating to chemical compounds and the uses thereof. If our compounds are found to infringe any such patents, we may have to pay significant damages or seek licenses to such patents. A patentee could prevent us from making, using or selling the patented compounds. We may need to resort to litigation to enforce a patent issued to us, protect our trade secrets or determine the scope and validity of third-party proprietary rights. From time to time, we may hire scientific personnel formerly employed by other companies involved in one or more areas similar to the activities conducted by us. Either we or these individuals may be subject to allegations of trade secret misappropriation or other similar claims as a result of their prior affiliations. If we become involved in litigation, it could consume a substantial portion of our managerial and financial resources, regardless of whether we win or lose. We may not be able to afford the costs of litigation. Any legal action against our company or our collaborators could lead to:

 

    payment of damages, potentially treble damages, if we are found to have willfully infringed a party’s patent rights;

 

    injunctive or other equitable relief that may effectively block our ability to further develop, commercialize and sell products; or

 

    we or our collaborators having to enter into license arrangements that may not be available on commercially acceptable terms, if at all.

 

As a result, we could be prevented from commercializing current or future products.

The patent applications of pharmaceutical and biotechnology companies involve highly complex legal and factual questions, which, if determined adversely to us, could negatively impact our patent position.

 

The patent positions of pharmaceutical and biotechnology companies can be highly uncertain and involve complex legal and factual questions. For example, some of our patent applications will cover gene sequences and products and the uses of those gene sequences and products. Public disclosures and patent applications related to the Human Genome Project and other genomics efforts may limit the scope of our claims or make unpatentable subsequent patent applications. No consistent policy regarding the breadth of claims allowed in biotechnology patents has emerged to date. The United States Patent and Trademark Office’s standards are uncertain and could change in the future. Consequently, the issuance and scope of patents cannot be predicted with certainty. Patents, if issued, may be challenged, invalidated or circumvented. U.S. patents and patent applications may also be subject to interference proceedings, and U.S. patents may be subject to reexamination proceedings in the United States Patent and Trademark Office (and foreign patents may be subject to opposition or comparable proceedings in the corresponding foreign patent office), which proceedings could result in either loss of the patent or denial of the patent application or loss or reduction in the scope of one or more of the claims of the patent or patent application. In addition, such interference, reexamination and opposition proceedings may be costly. Accordingly, rights under any issued patents may not provide us with sufficient protection against competitive products or processes.

 

In addition, changes in or different interpretations of patent laws in the United States and foreign countries may permit others to use our discoveries or to develop and commercialize our technology and products without providing any compensation to us. The laws of some countries do not protect intellectual property rights to the same extent as U.S. laws and those countries may lack adequate rules and procedures for defending our intellectual property rights. For example, some countries, including many in Europe, do not grant patent claims directed to methods of treating humans, and in these countries patent protection may not be available at all to protect our drug candidates.

 

If we fail to obtain and maintain patent protection and trade secret protection of our drug candidates, proprietary technologies and their uses, we could lose our competitive advantage and competition we face would increase, reducing our potential revenues and adversely affecting our ability to attain or maintain profitability.

 

Risks Related to Our Industry

 

We will be subject to stringent regulation in connection with the marketing of any products derived from our drug candidates, which could delay the development and commercialization of our products.

 

The pharmaceutical industry is subject to stringent regulation by the FDA and other regulatory agencies in the United States and by comparable authorities in other countries. Neither we nor our collaborators can market a pharmaceutical product in the United States until it has completed rigorous preclinical testing and clinical trials and an extensive regulatory clearance process implemented by the FDA. Satisfaction of regulatory requirements typically takes many years, depends upon the type, or complexity and novelty of the product and requires substantial resources. Even if regulatory approval is obtained, it may impose significant restrictions on the indicated uses, conditions for use, labeling, advertising, promotion and/or marketing of such products, and requirements for post-approval studies, including additional research and development and clinical trials. These limitations may limit the size of the market for the product or result in the incurrence of additional costs. Any delay or failure in obtaining required approvals could have a material adverse effect on our ability to generate revenues from the particular drug candidate.

 

Outside the United States, the ability to market a product is contingent upon receiving approval from the appropriate regulatory authorities. The requirements governing the conduct of clinical trials, marketing authorization, pricing and reimbursement vary widely from country to country. Only after the appropriate regulatory authority is satisfied that adequate evidence of safety, quality and efficacy has been presented will it grant a marketing authorization. Approval by the FDA does not automatically lead to the approval by regulatory

 

12


Table of Contents

authorities outside the United States, and similarly approval by regulatory authorities outside the United States will not automatically lead to FDA approval.

 

In addition, U.S. and foreign government regulations control access to and use of some human or other tissue samples in our research and development efforts. U.S. and foreign government agencies may also impose restrictions on the use of data derived from human or other tissue samples. Accordingly, if we fail to comply with these regulations and restrictions, the commercialization of our drug candidates may be delayed or suspended, which may delay or impede our ability to generate product revenues.

 

If our competitors develop and market products that are more effective than our drug candidates, they may reduce or eliminate our commercial opportunity.

 

Competition in the pharmaceutical and biotechnology industries is intense and expected to increase. We face competition from pharmaceutical and biotechnology companies, as well as numerous academic and research institutions and governmental agencies, both in the United States and abroad. Some of these competitors have products or are pursuing the development of drugs that target the same diseases and conditions that are the focus of our drug development programs.

 

For example, our potential product for treatment-induced dysfunctions in Parkinson’s disease would compete with off-label use of Seroquel, marketed by Astra-Zeneca, and the generic drug clozapine. Our potential products for the treatment of schizophrenia would compete with Zyprexa, marketed by Eli Lilly, Risperdal, marketed by Johnson & Johnson, Seroquel, marketed by Astra-Zeneca, and clozapine. In the area of neuropathic pain, our potential products would compete with Neurontin and Lyrica (pregabalin), marketed by Pfizer, and Cymbalta, marketed by Eli Lilly, as well as a variety of generic or proprietary opioids. Our potential products for the treatment of glaucoma would compete with Xalatan, marketed by Pfizer, and Lumigan and Alphagan, marketed by Allergan.

 

Many of our competitors and their collaborators have significantly greater experience than we do in the following:

 

    identifying and validating targets;

 

    screening compounds against targets;

 

    preclinical studies and clinical trials of potential pharmaceutical products; and

 

    obtaining FDA and other regulatory approvals.

 

In addition, many of our competitors and their collaborators have substantially greater capital and research and development resources, manufacturing, sales and marketing capabilities, and production facilities. Smaller companies also may prove to be significant competitors, particularly through proprietary research discoveries and collaboration arrangements with large pharmaceutical and established biotechnology companies. Many of our competitors have products that have been approved or are in advanced development and may develop superior technologies or methods to identify and validate drug targets and to discover novel small molecule drugs. Our competitors, either alone or with their collaborators, may succeed in developing drugs that are more effective, safer, more affordable or more easily administered than ours and may achieve patent protection or commercialize drugs sooner than us. Our competitors may also develop alternative therapies that could further limit the market for any drugs that we may develop. Our failure to compete effectively could have a material adverse affect on our business.

 

Any claims relating to improper handling, storage or disposal of biological, hazardous and radioactive materials used in our business could be costly and delay our research and development efforts.

 

Our research and development activities involve the controlled use of potentially harmful hazardous materials, including volatile solvents, biological materials such as blood from patients that has the potential to

 

13


Table of Contents

transmit disease, chemicals that cause cancer and various radioactive compounds. Our operations also produce hazardous waste products. We face the risk of contamination or injury from the use, storage, handling or disposal of these materials. We are subject to federal, state and local laws and regulations governing the use, storage, handling and disposal of these materials and specified waste products. The cost of compliance with these laws and regulations could be significant, and current or future environmental regulations may impair our research, development or production efforts. If one of our employees were accidentally injured from the use, storage, handling or disposal of these materials, the medical costs related to his or her treatment would be covered by our workers’ compensation insurance policy. However, we do not carry specific biological or hazardous waste insurance coverage and our general liability insurance policy specifically excludes coverage for damages and fines arising from biological or hazardous waste exposure or contamination. Accordingly, in the event of contamination or injury, we could be subject to criminal sanctions or fines or be held liable for damages, our operating licenses could be revoked, or we could be required to suspend or modify our operations and our research and development efforts.

 

Consumers may sue us for product liability, which could result in substantial liabilities that exceed our available resources and damage our reputation.

 

Researching, developing and commercializing drug products entails significant product liability risks. Liability claims may arise from our and our collaborators’ use of products in clinical trials and the commercial sale of those products. Consumers may make these claims directly and our collaborators or others selling these products may seek contribution from us if they receive claims from consumers. Although we currently have product liability insurance that covers our clinical trials, we will need to increase and expand this coverage as we commence larger scale trials and if our drug candidates are approved for commercial sale. This insurance may be prohibitively expensive or may not fully cover our potential liabilities. Inability to obtain sufficient insurance coverage at an acceptable cost or otherwise to protect against potential product liability claims could prevent or inhibit the commercialization of products that we or our collaborators develop. Product liability claims could have a material adverse effect on our business and results of operations. Our liability could exceed our total assets if we do not prevail in a lawsuit from any injury caused by our drug products.

 

Risks Related to Our Common Stock

 

Our stock price may be particularly volatile because we are a drug discovery and development company.

 

The market prices for securities of biotechnology companies in general, and early-stage drug discovery and development companies in particular have been highly volatile and may continue to be highly volatile in the future. The following factors, in addition to other risk factors described in this section, may have a significant impact on the market price of our common stock:

 

    the development status of our drug candidates, including results of our clinical trials for ACP-103, ACP-104, and our neuropathic pain collaboration;

 

    market conditions or trends related to biotechnology and pharmaceutical industries, or the market in general;

 

    announcements of technological innovations, new commercial products or other material events by our competitors or us;

 

    disputes or other developments concerning our proprietary rights;

 

    changes in, or failure to meet, securities analysts’ or investors’ expectations of our financial performance;

 

    additions or departures of key personnel;

 

    discussions of our business, products, financial performance, prospects or stock price by the financial and scientific press and online investor communities such as chat rooms;

 

14


Table of Contents
    public concern as to, and legislative action with respect to, genetic testing or other research areas of biopharmaceutical companies, the pricing and availability of prescription drugs or the safety of drugs and drug delivery techniques;

 

    regulatory developments in the United States and foreign countries; or

 

    economic and political factors, including wars, terrorism and political unrest.

 

In the past, following periods of volatility in the market price of a particular company’s securities, securities class action litigation has often been brought against that company. We may become subject to this type of litigation, which is often extremely expensive and diverts management’s attention.

 

If our officers, directors and largest stockholders choose to act together, they may be able to control our management and operations, acting in their best interests and not necessarily those of other stockholders.

 

Our directors, executive officers and holders of five percent or more of our outstanding common stock, as of April 20, 2005, and their affiliates beneficially owned approximately 47.5 percent of our common stock, based on their beneficial ownership at that time. As a result, these stockholders, acting together, have the ability to significantly influence all matters requiring approval by our stockholders, including the election of all of our directors, amendments to our certificate of incorporation, going-private transactions and the approval of mergers or other business combination transactions. The interests of this group of stockholders may not always coincide with our interests or the interests of other stockholders, and they may act in a manner that advances their best interests and not necessarily those of other stockholders.

 

If our stockholders sell substantial amounts of our common stock, the market price of our common stock may decline.

 

A significant number of shares of our common stock are held by a small number of stockholders. Sales of a significant number of shares of our common stock, or the expectation that such sales may occur, could significantly reduce the market price of our common stock. As of May 1, 2005, holders of approximately 10 million shares of our common stock have rights to cause us to file a registration statement, other than the registration statement that includes this prospectus, on their behalf for those shares or include those shares in registration statements that we may file on our behalf or on behalf of other stockholders. In addition, our stock price may decline as a result of the sale of the shares of our common stock offered by this prospectus.

 

Anti-takeover provisions in our charter documents and under Delaware law may make an acquisition of us more complicated and may make the removal and replacement of our directors and management more difficult.

 

Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that may delay or prevent a change in control, discourage bids at a premium over the market price of our common stock and adversely affect the market price of our common stock and the voting and other rights of the holders of our common stock. These provisions may also make it difficult for stockholders to remove and replace our board of directors and management. These provisions:

 

    establish that members of the board of directors may be removed only for cause upon the affirmative vote of stockholders owning at least a majority of our capital stock;

 

    authorize the issuance of “blank check” preferred stock that could be issued by our board of directors to increase the number of outstanding shares and prevent or delay a takeover attempt;

 

    limit who may call a special meeting of stockholders;

 

    establish advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted upon at stockholder meetings;

 

15


Table of Contents
    prohibit our stockholders from making certain changes to our amended and restated certificate of incorporation or amended and restated bylaws except with 66 2/3 percent stockholder approval; and

 

    provide for a board of directors with staggered terms.

 

We are also subject to provisions of the Delaware corporation law that, in general, prohibit any business combination with a beneficial owner of 15 percent or more of our common stock for three years unless the holder’s acquisition of our stock was approved in advance by our board of directors. Although we believe these provisions collectively provide for an opportunity to receive higher bids by requiring potential acquirors to negotiate with our board of directors, they would apply even if the offer may be considered beneficial by some stockholders.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

RESULTS OF OPERATIONS

 

The following discussion and analysis of our consolidated financial condition and results of operations should be read in conjunction with our consolidated financial statements and related notes included elsewhere in this prospectus. This discussion contains forward-looking statements, which involve a number of risks and uncertainties. Forward-looking statements are not guarantees of performance. Actual results or events may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under the caption “Risk Factors” in this prospectus. Information in the following discussion for a yearly period means for the year ended December 31 of the indicated year.

 

Overview

 

Background

 

We are a biopharmaceutical company focused on the discovery, development and commercialization of small molecule drugs for the treatment of central nervous system disorders. We currently have four drug programs in clinical development and several additional programs in preclinical and discovery stages. Our three Phase II clinical programs are ACP-103 for treatment-induced dysfunctions in Parkinson’s disease, ACP-103 as an adjunctive therapy for schizophrenia, and ACP-104 for the treatment of schizophrenia. We have retained worldwide commercialization rights for these programs. We also have a neuropathic pain program in Phase I clinical trials and a glaucoma program in preclinical development, each in collaboration with Allergan, Inc.

 

We have incurred substantial operating losses since our inception due in large part to expenditures for our research and development activities. At December 31, 2004, we had an accumulated deficit of $94.3 million. We expect our operating losses to increase for at least the next several years as we pursue the clinical development of our lead drug candidates and expand our discovery and development pipeline.

 

Revenues

 

We have not generated any revenues from product sales to date, and we do not expect to generate revenues from product sales for at least the next several years, if at all. Our revenues to date have been generated substantially from research and milestone payments under our collaboration agreements. We have entered into three separate collaboration agreements with Allergan. We have also entered into a development agreement with The Stanley Medical Research Institute, and smaller scale collaboration and license agreements with other parties. As of December 31, 2004, we had received an aggregate of $32.0 million in payments under these agreements, including research funding and related fees and upfront and milestone payments. In addition, in January 2005, we entered into a collaboration agreement with Sepracor Inc.

 

We expect our revenues for the next several years to consist of payments under our current agreements and any additional collaborations, including upfront payments upon execution of new agreements, research funding and related fees throughout the research term of the agreements and milestone payments contingent upon achievement of agreed-upon objectives. Pursuant to the terms of our March 2003 collaboration agreement with Allergan, we have received an aggregate of $7.9 million in research funding and related fees through December 31, 2004, and we are entitled to receive additional research funding and related fees through March 2006. In addition, we may receive milestone payments and royalties on product sales, if any, under each of our three collaboration agreements with Allergan. Revenues from our collaboration agreements with Allergan, a stockholder, are classified as “Collaborative revenues—related party” in the accompanying condensed consolidated financial statements. Pursuant to the terms of our January 2005 collaboration agreement with Sepracor, we are entitled to receive research funding for a three-year period and, if certain conditions are met, we are eligible to receive license fees and milestone payments as well as royalties on product sales, if any. Each of our collaboration agreements is subject to early termination by the collaborator upon specified events, including if we breach the agreement or, in one case, if we have a change in control. Upon the conclusion of the research term under each agreement, our collaborator may terminate the agreement by notice.

Research and Development Expenses

 

Our research and development expenses consist primarily of salaries and related personnel expenses, fees paid to external service providers, laboratory supplies and costs for facilities and equipment. We charge all research and development expenses to operations as incurred. Our research and development activities are primarily focused on our most advanced clinical and preclinical programs. We are responsible for all costs incurred in the development of ACP-103 for both schizophrenia and treatment-induced dysfunctions in Parkinson’s disease patients and in the development of ACP-104 for schizophrenia, as well as the research costs associated with our other internal drug programs. We are not responsible for, nor have we incurred, development expenses, including costs related to clinical trials, in the drug programs that we are pursuing under our collaboration agreements, including our clinical program for neuropathic pain and our preclinical development program for glaucoma, each of which we are pursuing in collaboration with Allergan.

 

We use our internal research and development resources, including our employees and discovery infrastructure, across several projects and many of our costs are not attributable to a specific project but are directed to broadly applicable research projects. Accordingly, we do not account for our internal research and development costs on a project basis. We use external service providers to manufacture our drug candidates to be used in clinical trials and for the majority of the services performed in connection with the preclinical and clinical development of our drug candidates. To the extent that costs associated with external service providers are not attributable to a specific project, they are included in other external costs. The following table summarizes our research and development expenses for the years ended December 31, 2004, 2003 and 2002.

At this time, due to the risks inherent in the clinical trial process and given the early stage of development of our drug programs, we are unable to estimate with any certainty the costs we will incur in the continued development of our drug candidates for potential commercialization. Due to these same factors, we are unable to determine the anticipated completion dates for our current research and development programs. Clinical development timelines, probability of success, and development costs vary widely. While we are currently focused on advancing the clinical development of ACP-103 and ACP-104, we anticipate that we will make determinations as to which programs to pursue and how much funding to direct to each program on an ongoing basis in response to the scientific and clinical success of each drug candidate, as well as an ongoing assessment as to the drug candidate’s commercial potential. In addition, we cannot forecast with any degree of certainty which drug candidates will be subject to future collaborative or licensing arrangements, when such arrangements will be secured, if at all, and to what degree such arrangements would affect our development plans and capital requirements. As a result, we cannot be certain when and to what extent we will receive cash inflows from the commercialization of our drug candidates.

 

We expect our research and development expenses to be substantial and to increase as we continue the development of our clinical programs, and as we continue and expand our preclinical and discovery programs. The lengthy process of completing clinical trials and seeking regulatory approval for our drug candidates requires the expenditure of substantial resources. Any failure by us or delay in completing clinical trials, or in obtaining regulatory approvals could cause our research and development expenses to increase and, in turn, have a material adverse effect on our results of operations.

Critical Accounting Policies and Estimates

 

Our discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements. We have identified the accounting policies that we believe require application of management’s most subjective judgments, often requiring the need to make estimates about the effect of matters that are inherently uncertain and may change in subsequent periods. Our actual results may differ substantially from these estimates under different assumptions or conditions. While our significant accounting policies are described in more detail in note 2 of the notes to consolidated financial statements included in this prospectus, we believe that the following accounting policies require the application of significant judgments and estimates.

 

Revenue Recognition

 

We recognize revenues in accordance with Securities and Exchange Commission Staff Accounting Bulletin, or SAB, No. 104, Revenue Recognition. SAB No. 104 requires that four basic criteria must be met before revenue can be recognized: persuasive evidence of an arrangement exists; delivery has occurred or services have been rendered; the fee is fixed and determinable; and collectibility is reasonably assured. Our revenues are primarily related to our collaboration agreements, and such agreements provide for various types of payments to us, including research funding, upfront payments, milestone payments, and royalties.

 

Upfront, nonrefundable payments under collaboration agreements are recognized ratably over the term of the agreement. Payments for research funding are recognized as revenues as the related research activities are performed. Our collaborations do not require scientific achievement as a performance obligation, and amounts received under the agreements are nonrefundable. Revenues from nonrefundable milestones are recognized when earned, provided that (i) the milestone event is substantive and its achievability was not reasonably assured at the inception of the agreement and (ii) we do not have ongoing performance obligations. Any amounts received under the agreements in advance of performance are recorded as deferred revenue. Revenues from licenses of our technology are generally recognized at the inception of the license term. When arrangements contain extended payment terms, revenues are recognized upon the receipt of the payment. None of the revenues recognized to date are refundable even if the related research activities are not successful.

 

Accrued Expenses

 

We are required to estimate accrued expenses as part of our process of preparing financial statements. This process involves estimating the level of service performed on our behalf and the associated cost incurred in instances where we have not been invoiced or otherwise notified of actual costs. Examples of areas in which subjective judgments may be required include costs associated with services provided by contract organizations for preclinical development, manufacturing of clinical materials, and clinical trials. We account for expenses associated with these external services by determining the total cost of a given study based on the terms of the related contract. We accrue for costs incurred as the services are being provided by monitoring the status of the trials and the invoices received from our external service providers. In the case of clinical trials, a portion of the estimated cost normally relates to the projected cost to treat a patient in our trials and we recognize this cost over the estimated term of the study based on the number of patients enrolled in the trial on an ongoing basis, beginning with patient enrollment. As actual costs become known to us, we adjust our accruals. To date, our estimates have not differed significantly from the actual costs incurred. However, we expect to expand the level of our clinical trials and related research and development services in the future. As a result, we anticipate that our estimated accruals for clinical and research services will be more material to our operations in future periods. Subsequent changes in estimates may be a material change in our accrual, which could also materially affect our results of operations.

 

Stock-based Compensation

 

We currently account for employee stock options using the intrinsic value method in accordance with Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees, and related

 

22


Table of Contents

interpretations, and provide pro forma disclosures of net income (loss) as if a fair value method had been applied in measuring compensation expense. Stock compensation expense, which is a non-cash charge, is measured as the excess, if any, of the fair value of our underlying common stock at the date of grant over the amount an employee must pay to acquire such stock. This compensation cost is amortized over the related vesting periods, generally four years, using an accelerated method.

 

In December 2004, the FASB issued SFAS No. 123 (revised 2004), Share-Based Payment, or SFAS 123(R), which requires that compensation costs relating to share-based payment transactions be recognized in financial statements. We are required to implement SFAS 123(R) in our first quarter of 2006. We are currently evaluating the requirements of SFAS 123(R) and we have not yet fully determined the impact on our consolidated financial statements.

 

Results of Operations

 

Fluctuations in Operating Results

 

Our results of operations have fluctuated significantly from period to period in the past and are likely to continue to do so in the future. We anticipate that our quarterly and annual results of operations will be impacted for the foreseeable future by several factors, including the timing and amount of payments received pursuant to our current and future collaborations, and the progress and timing of expenditures related to our discovery and development efforts. Due to these fluctuations, we believe that the period-to-period comparisons of our operating results are not a good indication of our future performance.

 

Comparison of the Years Ended December 31, 2004 and 2003

 

Revenues

 

Revenues decreased to $4.6 million in 2004 from $7.4 million in 2003 primarily due to a decrease in other collaborative research revenues, following the completion of the research term of our collaboration agreement with Amgen Inc. in late 2003. Revenues from our collaboration agreements with Allergan totaled $4.5 million and $5.0 million in 2004 and 2003, respectively, and are reflected as “collaborative revenues—related party” in our consolidated financial statements.

 

Research and Development Expenses

 

Research and development expenses increased to $23.5 million in 2004 from $16.9 million in 2003. This increase was primarily due to $3.5 million in increased fees paid to external service providers, and increased costs associated with our internal research and development activities, including $1.3 million in increased salaries and related personnel costs, $918,000 in increased laboratory supplies, and $730,000 in increased facility and equipment costs. External service costs totaled $7.7 million in 2004, or 33 percent of our research and development expenses, compared to $4.2 million in 2003, or 25 percent of our research and development expenses. The increase in external service costs in 2004 compared to 2003 was primarily attributable to increased clinical development expenses associated with ACP-103 and ACP-104. We expect that fees paid to external service providers will continue to increase in future periods as we continue to develop our drug candidates and expand our preclinical and discovery programs.

 

General and Administrative Expenses

 

General and administrative expenses, which consist primarily of salaries and related personnel expenses and facilities costs for employees serving in executive, finance, business development and business operations functions, as well as professional fees associated with legal and accounting services, increased to $4.9 million in 2004 from $2.8 million in 2003. The increase in general and administrative expenses was primarily due to $1.1 million in increased professional services and insurance costs and $828,000 in increased personnel and related expenses associated with operating as a public company, beginning in June 2004.

 

23


Table of Contents

Stock-Based Compensation Expenses

 

Stock-based compensation expenses totaled $2.4 million in 2004, compared to $1.4 million in 2003. The increase in stock-based compensation expenses resulted from an increase in the amortization of deferred stock-based compensation associated with employee stock options and compensation expense from the valuation of options granted to consultants. We recorded deferred stock-based compensation totaling $1.5 million and $3.0 million in 2004 and 2003, respectively, in connection with the grant of stock options to employees.

 

Interest Income

 

Interest income increased to $607,000 in 2004 from $360,000 in 2003. The increase in interest income was primarily due to higher average levels of cash and investment securities resulting from the proceeds of our initial public offering, which closed in June 2004.

 

Interest Expense

 

Interest expense decreased to $429,000 in 2004 from $713,000 in 2003. The decrease in interest expense was primarily due to repayments of and decreased borrowings under our loan agreements.

 

Comparison of the Years Ended December 31, 2003 and 2002

 

Revenues

 

Revenues increased to $7.4 million in 2003 from $6.3 million in 2002. The increase in revenues was primarily due to $1.3 million in increased revenues from our collaborations with Allergan with the inception of our third collaboration agreement in March 2003, and a $408,000 increase in revenues recognized under an agreement with Amgen, which were offset in part by lower revenues recognized under our technology license agreement with Aventis. Revenues from our collaboration agreements with Allergan totaled $5.0 million and $3.7 million in 2003 and 2002, respectively.

 

Research and Development Expenses

 

Research and development expenses increased to $16.9 million in 2003 from $14.9 million in 2002. This increase primarily reflected increased fees paid to external service providers, which totaled $4.2 million in 2003, or 25 percent of our research and development expenses, up from $2.3 million, or 15 percent of our research and development expenses, in 2002. The increase in external service fees in 2003 was primarily attributable to increased clinical and preclinical expenses associated with ACP-103.

 

The costs associated with our internal research and development activities, consisting primarily of salaries and related personnel expenses, laboratory supplies, and costs for facilities and equipment, totaled $12.7 million in 2003 and $12.6 million in 2002. Each component of our internal research and development costs was comparable in 2003 and 2002.

 

General and Administrative Expenses

 

General and administrative expenses totaled $2.8 million in 2003 and in 2002. Each component of these expenses, which consisted primarily of salaries and related personnel expenses and facilities costs for employees serving in executive, finance, business development and business operations functions, as well as professional fees associated with legal and accounting services, was comparable in 2003 and 2002.

 

Stock-based Compensation Expenses

 

Stock-based compensation expenses totaled $1.4 million in 2003 compared to $1.2 million in 2002. Stock-based compensation expenses resulted from the amortization of deferred stock-based compensation associated

 

24


Table of Contents

with employee stock options and compensation expense from the valuation of options granted to consultants. We recorded deferred stock-based compensation, net of forfeitures, totaling $3.0 million in 2003 and $(32,000) in 2002 in connection with the grant of stock options to employees.

 

Interest Income

 

Interest income decreased to $360,000 in 2003 from $420,000 in 2002. The decrease in interest income was primarily attributable to declining interest rates during the periods.

 

Interest Expense

 

Interest expense increased to $713,000 in 2003 from $662,000 in 2002. This increase in interest expense was primarily due to increased borrowings under our loan agreements.

 

Liquidity and Capital Resources

 

Since inception, we have funded our operations primarily through sales of our equity securities, payments under our collaboration agreements, debt financings and interest income. As of December 31, 2004, we had received $114.7 million in net proceeds from sales of our equity securities, including $6.9 million in debt we had retired through the issuance of our stock, $32.0 million in payments from collaboration agreements, $19.3 million in debt financing, and $6.1 million in interest income.

 

At December 31, 2004, we had approximately $35.9 million in cash, cash equivalents and investment securities compared to $27.2 million at December 31, 2003. In addition, in January 2005 we received $10 million in gross proceeds from the sale of 1,077,029 shares of our common stock to Sepracor in connection with a new collaboration agreement. Sepracor has also agreed to purchase an additional $10 million of our common stock on the one-year anniversary of the agreement at a 25 percent premium to the then 30-day trailing average closing price, subject to specified closing conditions set forth in a stock purchase agreement entered into by the parties. In April 2005, we also received net proceeds of approximately $34 million from the sales of shares of our common stock and warrants to purchase shares of our common stock in a private placement. We have invested a substantial portion of our available cash in investment securities consisting of high quality, marketable debt instruments of corporations and financial institutions. We have adopted an investment policy and established guidelines relating to diversification and maturities of our investments to preserve principal and maintain liquidity.

 

Net cash used in operating activities totaled $20.7 million in 2004, compared to $9.8 million in 2003 and $9.2 million in 2002. The increase in net cash used in operations in 2004 relative to 2003 was primarily due to an increase in our net loss, partially offset by increased non-cash, stock-based compensation expense and increases in accounts payable and accrued expenses. The increase in accounts payable and accrued expenses was primarily due to the increase in activity with external service providers and employee related expenses. The increase in net cash used in operations in 2003 relative to 2002 was primarily due to increases in our net loss, partially offset by an increase of $1.0 million in deferred revenues from our collaboration agreements.

 

Net cash used in investing activities (excluding purchases and maturities of investment securities) reflects our purchases of property and equipment. From inception through December 31, 2004, we purchased $10.1 million in property and equipment, the majority of which we have funded through equipment financing agreements and other debt facilities.

 

Net cash provided by financing activities totaled $30.1 million in 2004 compared to $26.4 million in 2003 and $4.4 million in 2002. The net cash provided by financing activities in 2004 was primarily due to net proceeds of approximately $31.1 million raised in our initial public offering, partially offset by $1.4 million in net repayments of our long-term debt. The increase in net cash provided by financing activities in 2003 relative to 2002 was primarily due to net proceeds of $28.0 million from the sale of preferred stock, partially offset by lower proceeds from long-term debt, net of repayments.

Table of Contents

We have entered into equipment financing agreements from time to time, which we have utilized to fund the majority of our property and equipment acquisitions. The agreements contain interest rates ranging from 7.93 to 9.58 percent per annum. At December 31, 2004, we had $2.0 million in outstanding borrowings under these agreements, which are secured by the related equipment. In May 2002, we also issued a secured promissory note to a lender for $5.0 million, which we utilized to finance equipment, leasehold improvements and other working capital needs. We had an outstanding balance of $560,000 under this promissory note at December 31, 2004, which was fully repaid in the first quarter of 2005. This note accrued interest at a rate of 10.73 percent per annum and was collateralized by substantially all personal property of the Company, excluding its intellectual property. We were in compliance with required financial covenants and conditions at December 31, 2004.

We have consumed substantial amounts of capital since our inception. Although we believe our existing cash resources, including the net proceeds from our private placement in April 2005, and the anticipated payments from existing agreements with our collaborators will be sufficient to fund our anticipated cash requirements through at least mid-2007, we will require significant additional financing in the future to fund our operations. Our future capital requirements will depend on, and could increase significantly as a result of, many factors, including:

 

    progress in, and the costs of, our preclinical studies and clinical trials and other research and development programs;

 

    the scope, prioritization and number of research and development programs;

 

    the ability of our collaborators and us to reach the milestones, and other events or developments, under our collaboration agreements;

 

    the costs involved in filing, prosecuting, enforcing and defending patent claims and other intellectual property rights;

 

    the costs of securing manufacturing arrangements for clinical or commercial production of drug candidates; and

 

    the costs of establishing, or contracting for, sales and marketing capabilities if we obtain regulatory clearances to market our drug candidates.

 

Until we can generate significant continuing revenues, we expect to satisfy our future cash needs through strategic collaborations, private or public sales of our securities, debt financings or by licensing all or a portion of our drug candidates or technology. We cannot be certain that additional funding will be available to us on acceptable terms, or at all. If funds are not available, we may be required to delay, reduce the scope of, or eliminate one or more of our research or development programs or our commercialization efforts.

 

To date, we have not had any relationships with unconsolidated entities or financial partnerships, such as entities referred to as structured finance or special purpose entities, which are established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

 

Recently Issued Accounting Standards

 

In December 2004, the FASB issued SFAS No. 123 (revised 2004), Share-Based Payment, or SFAS 123(R). This Statement is a revision of SFAS No. 123, Accounting for Stock-Based Compensation, and supersedes APB

 

26


Table of Contents

Opinion No. 25, Accounting for Stock Issued to Employees, and its related implementation guidance. SFAS 123(R) requires that compensation cost relating to share-based payment transactions be recognized in financial statements. That cost will be measured based on the fair value of the equity or liability instruments issued. This statement is effective beginning with the first quarter of 2006. We are currently evaluating the requirements of SFAS 123(R) and we have not yet fully determined the impact on our consolidated financial statements.

 

In March 2004, the FASB issued EITF Issue No. 03-01, The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments (“EITF 03-01”), which provides new guidance for assessing impairment losses on investments. Additionally, EITF 03-01 includes new disclosure requirements for investments that are deemed to be temporarily impaired. In September, 2004 the FASB delayed the accounting provisions of EITF 03-01; however the disclosure requirements remain effective for annual periods ending after June 15, 2004. We will evaluate the impact of EITF 03-01 once the final guidance is issued.

 

Quantitative and Qualitative Disclosures About Market Risk

 

Interest Rate Risk

 

We invest our excess cash in investment-grade, interest-bearing securities. The primary objective of our investment activities is to preserve principal while at the same time maximizing yields without significantly increasing risk. To achieve this objective, we invest in highly liquid and high quality marketable debt instruments of corporations, government agencies and financial institutions with maturities of less than two years. If a 10 percent change in interest rates were to have occurred on December 31, 2004, this change would not have had a material effect on the fair value of our investment portfolio as of that date.

 

Foreign Currency Risk

 

We have a wholly owned subsidiary in Denmark, ACADIA Pharmaceuticals A/S, which exposes us to foreign exchange risk. The functional currency of our subsidiary is the Danish kroner. Accordingly, all assets and liabilities of our subsidiary are translated to U.S. dollars based on the exchange rate on the balance sheet date. Expense components are translated to U.S. dollars at weighted average exchange rates in effect during the period. Gains and losses resulting from foreign currency translation are included as a component of our stockholders’ equity (deficit). Other foreign currency transaction gains and losses are included in our results of operations and, to date, have not been significant. We have not hedged exposures denominated in foreign currencies or any other derivative financial instrument.

BUSINESS

 

Overview

 

We are a biopharmaceutical company focused on the discovery, development and commercialization of small molecule drugs for the treatment of central nervous system disorders. We currently have four drug programs in clinical development and several additional programs in preclinical and discovery stages. Our three Phase II clinical programs are ACP-103 for treatment-induced dysfunctions in Parkinson’s disease, ACP-103 as an adjunctive therapy for schizophrenia, and ACP-104 for the treatment of schizophrenia. We have retained worldwide commercialization rights for these programs. We also have a neuropathic pain program in Phase I clinical trials and a glaucoma program in preclinical development, each in collaboration with Allergan, Inc. Using our proprietary drug discovery platform, we have discovered all of the drug candidates in our product pipeline.

 

The annual worldwide market for drugs used to treat schizophrenia and other psychoses exceeds $12 billion and the annual worldwide market for drugs used to treat Parkinson’s disease exceeds $2 billion. Current therapies in each of these two markets have substantial limitations, and we believe that significant opportunities exist for improved therapies.

 

In our first clinical program, we are developing ACP-103 to treat the debilitating psychiatric and neurological dysfunctions that frequently result from currently prescribed Parkinson’s disease therapies. We have completed a Phase Ib/IIa clinical trial that demonstrated safety and tolerability of ACP-103 in Parkinson’s disease patients, and we are currently conducting a multi-center Phase II clinical trial designed to evaluate the efficacy and safety of this drug candidate in Parkinson’s disease patients suffering from treatment-induced psychosis.

 

In our second clinical program, we are developing ACP-103 as an adjunctive therapy for schizophrenia, which means that, if approved, it will be used together with other drugs. We believe that the use of ACP-103 adjunctively will result in an improved antipsychotic therapy with better efficacy and lower side effects relative to existing therapies. We have completed a clinical study in healthy volunteers that showed that ACP-103 reduced side effects associated with treatment with haloperidol, an existing antipsychotic drug. We are currently conducting a multi-center Phase II clinical trial designed to evaluate the ability of ACP-103 to treat antipsychotic-induced side effects in patients with schizophrenia. We are preparing to conduct a larger multi-center Phase II clinical trial designed to evaluate the ability of ACP-103 when used adjunctively with other antipsychotic drugs to provide an improved therapy for patients with schizophrenia.

 

In our third clinical program, we are developing ACP-104 as a novel approach for the treatment of schizophrenia. Currently prescribed treatments often do not effectively address or may exacerbate cognitive disturbances associated with schizophrenia. We believe that ACP-104 may provide an effective antipsychotic therapy that may have the added advantage of improved cognitive function for patients with schizophrenia. We are currently conducting initial Phase II clinical trials for ACP-104 in patients with schizophrenia.

 

In our fourth clinical program, we have discovered a new class of compounds in collaboration with Allergan Inc. that we believe may represent a significant breakthrough in the treatment of neuropathic pain. Allergan is currently conducting Phase I clinical trials in this program. In addition to our clinical programs, we have discovered, and in collaboration with Allergan, are developing AC-262271, a small molecule drug candidate for the treatment of glaucoma. AC-262271 has been found to have a promising preclinical profile and has been selected for testing for lowering intraocular pressure in humans.

 

We have built a proprietary drug discovery platform that we use to rapidly discover new compounds that may serve as potential treatments for significant unmet medical needs. Our platform encompasses proprietary target-based and chemistry-based technologies that we integrate with our discovery and development

capabilities. We believe that the breadth of our discovery and development programs and the rapid pace at which we have discovered drug candidates provide strong validation of our proprietary platform and a basis for expanding our pipeline.

 

We leverage our proprietary drug discovery platform and expertise through collaborations with leading pharmaceutical and biotechnology companies. We have three collaborations with Allergan and one with Sepracor Inc. for the discovery and development of small molecule drug candidates and a technology license agreement with Aventis. To date, we have received research funding, upfront and milestone payments from our collaborators, and an equity investment from each of Allergan and Sepracor. We may receive additional payments, including research support, milestone payments and royalties on product sales.

 

We have assembled a management team with significant industry experience to lead the discovery, development and commercialization of our drug candidates. Members of our management team have contributed to the discovery, development and approval of multiple drug candidates to treat central nervous system disorders and are also experts in the application of gene, target and chemical technologies in drug discovery. We complement our management team with a network of scientific and clinical advisors that includes recognized experts in the fields of schizophrenia, Parkinson’s disease, and other central nervous system disorders.

 

Our Strategy

 

Our goal is to become a leader in the discovery, development and commercialization of novel small molecule drugs for the treatment of central nervous system disorders and other areas of unmet medical need. Key elements of our strategy are to:

 

    Develop and commercialize our lead drug candidates. We are focused on advancing the development of our three internal clinical programs, ACP-103 for treatment-induced dysfunctions in Parkinson’s disease, ACP-103 as an adjunctive therapy for schizophrenia, and ACP-104 for the treatment of schizophrenia. We intend to complete Phase II clinical trials in each of these programs. In therapeutic indications in which we have a cost-effective development path and believe our drug candidates could effectively be marketed by us, we intend to engage in late-stage clinical development and commercialization.

 

    Expand our pipeline of drug candidates for the treatment of central nervous system and related disorders. We plan to continue using our proprietary drug discovery platform and expertise to expand our pipeline of drug candidates for the treatment of central nervous system disorders and related disorders. We believe that these disorders represent significant market opportunities because current treatment options are suboptimal and produce adverse effects. We plan to expand our pipeline to include additional clinical programs that address a range of neuropsychiatric and related disorders. We believe that our diversified pipeline of programs will mitigate the risks inherent in drug discovery and development and increase the likelihood of commercial success.

 

    Selectively establish strategic collaborations to advance and maximize the commercial potential of our pipeline. We will continue to pursue selective strategic collaborations to leverage the development, regulatory and commercialization expertise of our partners. However, we plan to retain selected commercialization rights to our products where we can pursue specialty markets that could result in significant financial return on our investment. In therapeutic indications that do not have a cost-effective development path or require a large sales force, we plan to complete late-stage clinical development and commercialization of our drug candidates through, or in collaboration with, collaborators.

 

   

Leverage our proprietary drug discovery platform to identify novel drug candidates outside of our core focus. In addition to our focus on central nervous system disorders, we are leveraging our proprietary drug discovery platform to identify novel drug candidates in therapeutic areas outside of our core focus that we may develop independently or in partnerships. Our platform has broad applicability in a variety of therapeutic areas, including ophthalmology, endocrinology, metabolic disorders and oncology. To date, we

 

29


Table of Contents
 

have formed collaborations with Allergan in the area of ophthalmology. We may continue to selectively partner or out-license drug candidates in therapeutic areas outside of our core focus.

 

    Maintain and enhance our technology leadership position. We believe we are a leader in small molecule discovery with expertise in molecular biology, ultra-high throughput screening, pharmacology and chemistry. Currently we have three proprietary target-based platforms that incorporate some of the largest gene families that include the most relevant targets for small molecule drug discovery. These platforms utilize proprietary screening and pharmacology tools. We are also developing additional target platforms that incorporate other gene families of pharmaceutical interest. In addition, we will continue to augment our proprietary combinatorial chemistries and expand our diverse compound library.

 

    Opportunistically in-license or acquire complementary technologies and drug candidates. Although we have discovered all of the drug candidates currently in our pipeline, we believe that in-licensing or acquiring technologies and drug candidates that complement our capabilities may enable us to expand our product pipeline more rapidly and enhance our state-of-the-art discovery capabilities. Therefore, in the future, we may elect to in-license or acquire complementary technologies and augment our internal pipeline with clinical products.

 

Our Drug Development Programs

 

Our drug development programs include four programs in clinical development and one program in preclinical development. Our programs address diseases that are not well served by currently available therapies and represent large commercial market opportunities. We believe that our drug candidates offer innovative therapeutic approaches and may provide significant advantages relative to current therapies. The following table summarizes our five drug development programs:

Treatment-Induced Dysfunctions in Parkinson’s Disease

 

Disease and Market Overview

 

Parkinson’s disease is a chronic, progressive neurological disorder that results from the degeneration of neurons in a region of the brain that controls movement. This degeneration creates a shortage of an important brain signaling chemical, or neurotransmitter, known as dopamine, rendering patients unable to initiate their movements in a normal manner. Parkinson’s disease is characterized by a number of symptoms including tremors, limb stiffness, slowness of movements, and difficulties with posture and balance. The severity of Parkinson’s disease symptoms tends to worsen over time.

 

According to the American Parkinson’s Disease Association, over 1.5 million people in the United States suffer from this disease. Parkinson’s disease is more prevalent in people over 60 years of age, and the incidence and prevalence of this disease is expected to increase as the average age of the population increases. In 2003, approximately $2.3 billion was spent on drug therapy worldwide to treat Parkinson’s disease.

 

Parkinson’s disease patients are currently treated with dopamine replacement therapies such as levodopa, commonly referred to as L-dopa, and dopamine agonists, which are molecules that mimic the action of dopamine. These therapies are relatively effective in controlling the symptoms of the disease in most patients. However, the use of these agents normally is required throughout the course of the disease and often results in a

Table of Contents

range of side effects that are not effectively treated with marketed drugs. These side effects may include neuropsychiatric abnormalities such as hallucinosis and psychosis, as well as uncontrollable movements of the limbs, referred to as dyskinesias. Studies have suggested that approximately 30 percent of Parkinson’s disease patients that are undergoing dopamine replacement therapies will develop hallucinosis, typically consisting of visual hallucinations, with a smaller portion of these patients developing a state of psychosis. These abnormalities are often disabling, and drug-induced psychosis is the most important factor leading to nursing home placements of Parkinson’s disease patients. In addition, drug-induced dyskinesias are estimated to occur in up to 80 percent of Parkinson’s disease patients after five years of receiving available therapies. Currently, there is a large unmet medical need for new therapies that will effectively control or eliminate the dose-limiting side effects that result from the use of dopamine replacement therapies in the treatment of Parkinson’s disease.

 

There have been numerous attempts to use existing antipsychotic drugs to treat the neuropsychiatric abnormalities caused by the treatment of Parkinson’s disease patients. Because antipsychotic agents worsen the preexisting brain dopamine deficit, these drugs are generally not well-tolerated by Parkinson’s disease patients. One antipsychotic drug therapy that has demonstrated efficacy in reducing the treatment-induced psychosis in Parkinson’s disease patients without further impairing motor function is low-dose treatment with the generic drug clozapine. Our studies suggest that this unique clinical utility of clozapine arises from its ability to block a key serotonin receptor, a protein that responds to the neurotransmitter serotonin, known as the 5-HT2A receptor. The U.S. Food and Drug Administration, or FDA, has not approved any therapy for treatment-induced psychotic disorders in Parkinson’s disease. However, in Europe, the use of low-dose clozapine has been approved for this indication. Seroquel, an antipsychotic drug, is also used off-label for this indication in both the United States and in Europe.

 

ACP-103 for Treatment-Induced Dysfunctions in Parkinson’s Disease

 

Overview

 

ACP-103 is a small molecule drug candidate that we discovered and are developing to treat the debilitating psychiatric and neurological dysfunctions produced by current Parkinson’s disease therapies, thereby significantly improving the quality of life for Parkinson’s disease patients. ACP-103 is a potent and selective 5-HT2A inverse agonist, a compound that blocks the activity of the 5-HT2A receptor. We believe that ACP-103 may effectively treat the hallucinosis, psychosis and dyskinesias that frequently result from the use of existing Parkinson’s disease medications. Because ACP-103 does not interact with dopamine receptors, it is not expected to impair motor function.

 

Development Status

 

We are currently conducting a multi-center, double-blind, placebo-controlled Phase II trial designed to evaluate the efficacy and safety of ACP-103 in Parkinson’s disease patients suffering from treatment-induced psychosis without impairing motor skills. We expect to enroll a total of 60 Parkinson’s disease patients in this trial at several clinical sites in the United States. The study involves once-daily oral administration of either ACP-103 at selected doses or a placebo for four weeks to patients who also receive their stable dopamine-replacement therapy. Efficacy is assessed by a battery of standard rating scales and by physicians’ global impressions of change at multiple times throughout the study period. We modeled the study design of this clinical trial after a study conducted by The Parkinson Study Group, which was a double-blind, placebo-controlled trial that demonstrated the efficacy of clozapine at low doses in this indication. We are planning to report results from this trial at two points during the study. By mid-2005, we intend to report on potential trends in patient responses to ACP-103 seen in the first 30 patients to complete the study. This initial examination will be limited to trends relative to the trial’s endpoints of efficacy. We are continuing to enroll patients in this trial and we expect to report results from a complete statistical analysis of all clinical endpoints on all 60 patients in late-2005 or early-2006. We also have an ongoing study involving the extended use of ACP-103 in Parkinson’s disease patients with treatment-induced psychosis who have completed the aforementioned Phase II trial and may, in the opinion of the treating physician, benefit from continued treatment with ACP-103. This is an open-label extension study, which is designed to determine the safety of ACP-103 during long-term administration.

During the second quarter of 2004, we reported results from a double-blind, placebo-controlled Phase Ib/IIa clinical trial with ACP-103 comprised of 12 Parkinson’s disease patients on standard dopamine replacement therapy. This clinical trial evaluated the safety and tolerability of ACP-103 in Parkinson’s disease patients following administration of 25 and 100 milligram doses once-daily for 14 days. ACP-103 was well-tolerated in these patients. Importantly, the motor skills of these patients did not deteriorate, an effect commonly seen with other antipsychotic drugs. In addition, patients who entered this trial with treatment-induced dyskinesias exhibited indications of antidyskinetic activity after ACP-103 administration. This outcome is consistent with the previously demonstrated antidyskinetic activity of ACP-103 in a monkey model of Parkinson’s disease. Following this Phase Ib/IIa clinical trial, we initiated a clinical pharmacology study to further evaluate the ability of ACP-103 to treat levodopa-induced dyskinesias in patients with Parkinson’s disease. This study is being conducted at the National Institutes of Neurological Disorders and Stroke, an institute of the National Institutes of Health.

 

In 2003, we completed two Phase I clinical trials that assessed the safety, tolerability and blood levels of ACP-103 following oral administration in a total of 57 healthy volunteers. These randomized, double-blind, placebo-controlled, dose-escalation trials encompassed both single-dose and multiple-dose studies. The single-dose study evaluated five different dose levels ranging from 20 to 300 milligrams, which resulted in mean maximum plasma levels ranging from nine to 152 nanograms per milliliter. The multiple dose-escalation study evaluated three different dose levels, ranging from 50 to 150 milligrams administered once-daily for 14 days, which resulted in mean maximum plasma levels at steady state ranging from 93 to 247 nanograms per milliliter. In both the single-dose and multiple-dose studies, ACP-103 exhibited consistent drug levels in the blood and a long half-life that we believe make our drug candidate ideal for once-daily dosing. ACP-103 was well-tolerated at plasma levels of 229 nanograms per milliliter and below with no changes in cardiovascular or neurological function and no serious adverse events in the healthy volunteers at any plasma level of ACP-103.

 

In addition to our Phase I clinical trials of ACP-103, we also conducted drug receptor occupancy studies in healthy volunteers in collaboration with the Karolinska Institute, a prominent Swedish research center, using non-invasive, positron emission tomography, or PET, with various single doses of ACP-103. This study demonstrated that even low acute oral doses of this drug candidate produce significant occupancy of 5-HT2A receptors in the human brain. We believe that the results from this PET study support that ACP-103 has a wide separation between the plasma drug levels that are predicted for clinical efficacy and the plasma levels shown to be safe and well-tolerated in our Phase I and Phase Ib/IIa clinical trials.

that yields an estimated plasma drug level of approximately three nanograms per milliliter. This dose leads to significant occupancy of 5-HT2A receptors in the neocortex of the brain. Darker regions in the neocortex on the left half of the image show the PET-labeled 5-HT2A receptors. These receptors are not visible on the right because they are being blocked, or occupied, by ACP-103 treatment. Based on these PET data and the results of our Phase I and Phase Ib/IIa clinical trials, we believe that low doses of ACP-103 will be sufficient to demonstrate efficacy in our clinical trials.

 

Schizophrenia

 

Disease and Market Overview

 

Schizophrenia is a debilitating mental illness characterized by disturbances in thinking, emotional reaction and behavior. These disturbances may include positive symptoms, such as hallucinations and delusions and a range of negative symptoms, including cognitive disturbances. Schizophrenia is associated with persistent impairment in a patient’s social functioning and productivity. It is believed that cognitive disturbances prevent patients with schizophrenia from readjusting to society. As a result, schizophrenia requires patients to be under medical care for their entire lives.

 

According to the National Institute of Mental Health, approximately one percent of the population develops schizophrenia during their lifetime and more than two million people in the United States suffer from this disease. Worldwide sales of drugs to treat schizophrenia and other psychoses totaled approximately $12.2 billion in 2003. Currently, schizophrenia is treated by administration of first generation, known as typical, or second generation, known as atypical, antipsychotic agents. The typical antipsychotic agents that were introduced in the late-1950s block dopamine receptors. This class of compounds is effective against positive symptoms of schizophrenia but also produces disabling motor disturbances, including akathesia, an extremely distressful motor disturbance characterized by feelings of inner restlessness and an urge to move. Typical antipsychotic drugs fail to address or worsen most of the negative symptoms of schizophrenia, and their use has decreased in the United States and Europe.

 

Atypical antipsychotic drugs produce fewer motor disturbances than typical antipsychotic agents, but also fail to address most of the negative symptoms of schizophrenia. It is believed that the efficacy of atypical antipsychotic drugs is due to their interactions with dopamine and 5-HT2A receptors. The side effects produced by the atypical agents include severe obesity, type II diabetes and cardiovascular side effects. We believe that these side effects arise from non-essential receptor interactions that are unrelated to their actions at receptors driving their efficacy.

 

In spite of the availability of a variety of antipsychotic agents, only a portion of the negative symptoms of schizophrenia are treatable and, in particular, the cognitive disturbances are poorly addressed by current therapies. Clozapine, more so than other atypical antipsychotics, appears to have the ability to partially address cognitive disturbances while typical antipsychotic drugs frequently worsen the cognitive function of the patients. We believe there is a large unmet medical need for therapies that address both the positive and negative symptoms of schizophrenia and produce fewer side effects.

 

We have two development programs that we believe offer innovative therapeutic solutions to major unmet medical needs in schizophrenia.

 

ACP-103 as an Adjunctive Therapy for Schizophrenia

 

Overview

 

We are developing ACP-103 as an adjunctive therapy to be used together with other antipsychotic drugs to treat schizophrenia. ACP-103 can be taken orally and is a small molecule drug candidate that acts as a potent and selective inverse agonist at 5-HT2A receptors. Antipsychotic drugs produce a range of side effects that arise

 

33


Table of Contents

either from off-target receptor interactions or excessive dopamine blockade. By identifying and correlating the molecular properties of marketed antipsychotic drugs with their clinical actions, we have identified inverse agonism at 5-HT2A receptors as essential to the improved clinical profile of atypical antipsychotic drugs. By adding ACP-103 to existing treatment regimens, we believe the optimal combination of dopamine receptor blockade and 5-HT2A inverse agonism can be achieved with a range of typical and atypical antipsychotic drugs. This adjunctive therapy may result in better efficacy and lower side effects.

 

Development Status

 

We are currently conducting a multi-center, double-blind, placebo-controlled Phase II clinical trial designed to evaluate the ability of ACP-103 to treat side effects associated with chronic treatment with haloperidol, a typical antipsychotic drug, in up to 40 patients with schizophrenia. This clinical study involves once-daily oral administration of either ACP-103 or a placebo for a five-day period. Efficacy is assessed by the use of standard rating scales at multiple times throughout the study period. We are planning to report results from this trial during the second half of 2005.

 

We currently are preparing to initiate the clinical phase of a multi-center, double-blind, placebo-controlled Phase II clinical trial designed to evaluate the ability of ACP-103 when used adjunctively with other antipsychotic drugs to provide an improved therapy for patients with schizophrenia. This clinical trial will explore the ability of ACP-103 in adjunctive therapy with each of risperidone, an atypical antipsychotic drug, and haloperidol to reduce acute exacerbations of schizophrenia. We expect to enroll up to 400 patients with schizophrenia, who will be randomly assigned to one of five treatment groups. These groups will include treatment with ACP-103 together with selected doses of either risperidone or haloperidol, and three additional groups consisting of treatment with specified doses of risperidone or haloperidol. We will assess efficacy on positive and negative symptoms and tolerability using a battery of standard psychiatric and neurological rating scales. A formal interim analysis is planned for this study after 200 patients have completed the trial. We expect to begin the clinical phase of this trial during the second quarter of 2005.

 

During the third quarter of 2004, we reported results of a clinical study designed to assess the ability of ACP-103 to reduce the side effects associated with drug treatment with haloperidol. This double-blind, placebo-controlled study involved 18 healthy volunteers. All subjects were administered a single 7.5 milligram dose of haloperidol and the majority of these subjects developed measurable akathisia. In addition, the haloperidol treatment induced approximately a three-fold increase in prolactin secretion. This condition of elevated prolactin secretion may adversely affect menstrual and sexual function and bone formation. The results of the study indicated that a single dose of ACP-103 reduced akathisia symptoms in most subjects. In addition, ACP-103 reduced haloperidol-induced increases in prolactin secretion by 33 percent.

 

ACP-104 as a Treatment for Schizophrenia Providing Potential Cognitive Benefits

 

Overview

 

ACP-104 is a small molecule drug candidate that we are developing as a novel, stand-alone therapy for schizophrenia. It is known that large amounts of ACP-104, or N-desmethylclozapine, are formed in the body after administration of clozapine. That is, clozapine is metabolized to ACP-104. We discovered that ACP-104 has a unique ability to stimulate m1 muscarinic receptors. The m1 muscarinic receptors are widely known to play an important role in cognition. Since clozapine itself blocks the m1 muscarinic receptor, patients need to extensively metabolize clozapine into ACP-104 to stimulate this receptor and thereby overcome the blocking action of clozapine. Administration of ACP-104 will avoid the variability of this metabolic process and the competing action of clozapine. Like clozapine, ACP-104 interacts with dopamine and 5-HT2A receptors. We believe that ACP-104 represents a new approach to schizophrenia therapy that combines an atypical antipsychotic efficacy profile with the added advantage of beneficial cognitive effects.

Table of Contents

Development Status

 

We are currently conducting the initial studies in our Phase II clinical program for ACP-104. The initial studies are double-blind, placebo-controlled, single-dose and multiple-dose escalation trials in patients with schizophrenia. These trials are focused primarily on safety and drug levels in the blood, but may also provide preliminary indications of the efficacy of ACP-104 in patients with schizophrenia. We plan to use these studies to determine the doses required to achieve plasma levels of ACP-104 similar to those seen after clozapine administration. We are also conducting a preliminary assessment of antipsychotic and cognitive efficacy of ACP-104 using standard rating scales in these two trials. We are planning to report results from these initial studies in the second half of 2005. Following completion of these initial studies, we plan to conduct additional studies to further assess the efficacy of ACP-104 in the treatment of patients with schizophrenia and cognitive disturbances.

 

We have analyzed data on clozapine and ACP-104 plasma levels relative to clinical response from two clinical trials that included 92 patients with schizophrenia treated with clozapine for up to six months. We demonstrated in this study that the plasma drug ratio of ACP-104 to clozapine positively predicts improvement in cognitive functioning and quality of life parameters in these patients. This study indicated that a higher ratio of ACP-104 relative to clozapine resulted in a better response by these patients in a wide range of standard cognitive functioning and quality of life clinical measures. The results of this study and our preclinical tests suggest that due to its robust m1 receptor activation, ACP-104 is responsible for the unique cognitive benefits of clozapine.

 

As ACP-104 is a metabolite of clozapine, millions of patients worldwide have been exposed to ACP-104 over the last 30 years. Over 70 clinical studies are available in the scientific literature in which the serum levels of ACP-104 were reported in patients with schizophrenia treated with clozapine. The total patient exposure to ACP-104 presented in these studies alone exceeds 2,000 patients. ACP-104 serum levels are highly correlated with clozapine serum concentrations and on average are approximately 70 percent of clozapine levels. Across the 25 to 1,000 milligrams per day dose range of clozapine used in these studies, the steady state serum level of ACP-104 achieved in patients with schizophrenia was as high as 1,500 nanograms per milliliter. Importantly, clozapine therapy and the resulting ACP-104 levels of this magnitude were tolerated by the patients in these studies. These studies provide an extensive clinical database that enables us to select doses that yield a wide range of plasma levels of ACP-104, corresponding to those plasma levels of ACP-104 that are achieved in clozapine-treated patients. Therefore, we believe that we may be able to rely on the significant previous exposure of ACP-104 in humans to demonstrate and support the safety of ACP-104.

 

Neuropathic Pain

 

Disease and Market Overview

 

Neuropathic pain is a common and growing subset of pain that is thought to involve an alteration in nervous system function or a reorganization of nervous system structure. Neuropathic pain can be associated with nerve damage caused by trauma, diseases such as diabetes, shingles, irritable bowel syndrome, late-stage cancer or the toxic effects of chemotherapy. In many patients, damage to sensory nerves is accompanied by varying degrees of pain. The experience can range from mildly increased sensitivity to touch or temperature to excruciating pain. This kind of pain is usually chronic and extremely difficult to manage clinically because it fails to respond to most medications currently used to treat other forms of pain. According to Pharmaprojects, a healthcare publication, each year approximately 26 million people worldwide suffer from some form of neuropathic pain.

 

Drugs such as opioid painkillers and nonsteroidal anti-inflammatory agents that are effective in treating inflammatory and acute pain usually are not effective in treating neuropathic pain. Opioid painkillers provide suboptimal pain management and have significant adverse side effects that limit their usefulness, including respiratory depression, nausea, vomiting, dizziness, sedation, mental clouding, constipation, urinary retention and severe itching. In addition, prolonged chronic use of opioid painkillers can lead to the need for increasing dosage and potentially to addiction. Currently, the market leading treatment for neuropathic pain is Neurontin, which had

worldwide sales of approximately $2.7 billion in 2004. In addition, two drugs, Lyrica (pregabalin) and Cymbalta, have been recently approved for this indication. We believe that there is a large unmet medical need for new therapies with improved efficacy and side effect profiles.

 

Our Drug Candidates for Neuropathic Pain

 

In collaboration with Allergan, we have discovered and are developing a new class of small molecule drug candidates that we believe provide the potential for a significant breakthrough in the treatment of neuropathic pain. Using our proprietary drug discovery platform, we have identified a previously unappreciated target for neuropathic pain, which is a key alpha adrenergic receptor subtype. We have discovered and are developing orally active small molecule drug candidates that selectively activate this target. Our novel and selective alpha adrenergic agonists provide highly effective pain relief in a wide range of preclinical models, without the side effects of current pain therapies, including sedation and cardiovascular and respiratory effects. Allergan has demonstrated that these drug candidates are highly potent and efficacious when administered orally in relevant animal models and are more efficacious than Neurontin in preclinical models at 300-to-1,000 fold lower doses. Based on the compelling preclinical profile of our drug candidates, we believe that these drug candidates may represent a new class of highly effective and safe therapeutics for neuropathic pain.

 

Together with Allergan, we have nominated two orally active, small molecule drug candidates, AGN-XX and AGN-YY, for development. Allergan filed an Investigation New Drug application with the FDA during the third quarter of 2004 and is currently conducting Phase I clinical trials in this program.

Glaucoma is an eye disease that, if left untreated, can lead to degeneration of the optic nerve and blindness. Glaucoma is the second leading cause of blindness in the United States. A prevalent symptom of glaucoma is increased fluid pressure within the eye, or intraocular pressure. According to the Glaucoma Research Foundation, an estimated three million people in the United States and 67 million people worldwide have glaucoma. In 2002, worldwide sales for glaucoma therapeutics totaled $2.3 billion. It is expected that worldwide sales of glaucoma therapeutics will increase significantly as awareness and diagnoses increase and the general population ages. Currently, physicians treat glaucoma with multiple classes of therapeutics to optimize therapy and minimize side effects. We believe significant market demand exists for new glaucoma therapies that offers superior efficacy with minimal side effects.

 

AC-262271 for treatment of Glaucoma

 

We have discovered, and in collaboration with Allergan, are developing AC-262271, a small molecule drug candidate for the treatment of glaucoma. Allergan is currently conducting studies with AC-262271 in preparation for possible clinical trials. AC-262271 uses a new therapeutic mechanism to produce a highly effective and long lasting reduction of intraocular pressure in primate models of glaucoma. Using our proprietary drug discovery platform, we identified a subtype of the muscarinic receptor that controls intraocular pressure and discovered lead compounds that selectively activate this target. In a primate model of glaucoma, AC-262271 demonstrated efficacy and a long duration of action without causing visual disturbances, such as accommodation. Preclinical data for AC-262271 suggests that this drug candidate has the potential to be a promising new therapy for glaucoma.

 

Our Preclinical Discovery Programs

 

In addition to our five development programs, we have established preclinical discovery programs in the areas of muscarinic receptors, 5-HT2 receptors, and androgen receptors, or ARs. We have extensive expertise and discovery assets in these areas, which provide us with a wide range of therapeutic opportunities. Our efforts in these three areas have already led to our three proprietary development programs as well as additional programs currently in preclinical testing.

Preclinical Muscarinic Program

 

Our muscarinic program is designed to deliver new drug candidates to treat psychosis, cognitive disturbances in patients with schizophrenia and dementia, and neuropathic pain. One aspect of our muscarinic program involves the investigation of our muscarinic agonists that selectively target the m1 muscarinic receptor and may represent a novel approach to the treatment of cognition in patients with schizophrenia. We have discovered over 300 potent muscarinic agonists that selectively target the m1 muscarinic receptor. These muscarinic agonist compounds inhibit behaviors associated with psychotic states and enhance cognitive function in preclinical animal models. We have also identified the muscarinic receptor subtype that we believe alleviates neuropathic pain. We have used genetically altered mice that lack the relevant muscarinic receptor subtype to support our efforts in this program and we have identified novel sites for muscarinic receptor/drug interactions that yield, for the first time, truly selective muscarinic agonists. Such compounds have not shown the side effects typical of non-selective muscarinic agents, but show robust effects in animal models of psychosis, cognition and neuropathic pain. The promising preclinical profile of our selective muscarinic compounds suggests significant therapeutic potential. In January 2005, we formed a collaboration with Sepracor that will explore potential clinical candidates resulting from our muscarinic program. We have previously used this program to discover the unique muscarinic agonist action of ACP-104 and a series of preclinical analogs of ACP-104. We have retained all rights related to each of these compounds.

 

Preclinical 5-HT2 Program

 

We use our 5-HT2 program to generate new drug candidates to treat neuropsychiatric and related central nervous system disturbances. We discovered ACP-103, a potent and selective 5-HT2A inverse agonist, in this program. We have synthesized a large number of additional compounds having diverse pharmacological and pharmaceutical properties that interact with the various 5-HT2 and related receptor subtypes. These compounds may also be used to modify sleep architecture, particularly deep sleep that is commonly disturbed in the elderly. In connection with our collaboration agreement with Sepracor formed in January 2005, Sepracor has the option to select one preclinical compound from this program for use in combination with LUNESTA, Sepracor’s insomnia drug, for sleep-related indications. We will retain the rights to all other compounds in this program.

 

Preclinical AR Program

 

We have identified novel, potent and selective non-steroidal small molecule agonists of the androgen receptor. These compounds are orally bioavailable and demonstrate robust testosterone-like endocrine effects without enlarging the prostate. The potential therapeutic applications for AR agonists include indications such as hormone replacement therapies to treat osteoporosis, sexual dysfunctions and muscle wasting, as well as therapies for dry eye and various central nervous system disorders.

 

Our Drug Discovery Platform and Capabilities

 

Overview

 

We have established drug discovery and technical expertise in the areas of molecular biology, ultra-high throughput screening, molecular and behavioral pharmacology, and combinatorial, medicinal and analytical chemistry. In addition, we collaborate with world-renowned scientists, clinicians and academic institutions. We believe that our expertise combined with our proprietary drug discovery platform has allowed us to discover drug candidates more efficiently than traditional approaches.

 

All of our drug candidates that are currently in clinical trials, preclinical testing and earlier stages of discovery were discovered using our proprietary drug discovery platform. We have integrated our discovery and development capabilities with proprietary target-based and chemistry-based technologies. We have demonstrated that our platform can be used to rapidly identify drug-like, small molecule chemistries for a wide range of drug targets. We believe that the breadth of our discovery and development programs and the rapid pace at which we have discovered drug candidates provide strong validation of our proprietary platform and a basis for expanding our pipeline.

Our Chemical-Genomics Discovery Approach

 

Our drug discovery approach is designed to introduce chemistry at an early stage in the drug discovery process and enable selection of the most attractive, drug-like chemistries for desired targets that we validate with past clinical experience. A key to our approach, which we refer to as a chemical-genomics discovery approach, is our comprehensive set of proprietary functional test systems, or assays, that we developed for members of two important gene families, G-protein coupled receptors, or GPCRs, and nuclear receptors, or NRs, which believe represent the most relevant and feasible targets for small molecule drug discovery. We have also developed assays for other relevant targets, including tyrosine kinase linked receptors, or RTKs. We use our proprietary assays to validate drug targets and to discover novel small molecule drug candidates that are specific for these targets using two complementary approaches.

 

Our first approach is to validate potential drug targets. We profile our collection of reference drugs, primarily consisting of currently and formerly marketed central nervous system drugs, over the range of targets in our functional assays to link clinical and physiological effects of drugs with specific drug targets. Using our reference-drug approach, we are able to identify key drug targets that are validated with past clinical experience as well as the targets that we believe are responsible for various side effects of these drugs. Our discoveries of ACP-103 and ACP-104 resulted from the successful application of our reference-drug approach. The only property that we have found to predict atypical antipsychotic clinical activity is inverse agonism at the 5-HT2A receptor. This important finding led us to the discovery of selective 5-HT2A inverse agonists that we are developing as treatments for a variety of central nervous system disorders. In the case of ACP-104, we found that, of all of the clinical compounds within our reference library, only ACP-104 was a robust m1 muscarinic agonist, thus suggesting the cognitive benefits of ACP-104.

 

Our second approach is to broadly screen large numbers of targets for the most attractive small molecule chemistries. These chemistries may be prioritized and used as starting points for our drug discovery programs. Using this approach, we discovered that one of our target-specific chemistries demonstrated activity in preclinical models of neuropathic pain, providing the starting point for our collaborative neuropathic pain development program. Similarly, one of our selective muscarinic agonists was active in a glaucoma model without showing classical side effects, providing the starting point for our collaborative glaucoma development program.

Our Target-Based Discovery Technologies

 

Overview

 

The human genome project has provided information about the genetic structure of essentially all of the potential drug targets in the human genome. This knowledge, when combined with our proprietary technologies, allows for the efficient testing of the effects of chemical compounds on a wide range of potential drug targets. Within the human genome there are families of genes that include the most frequent targets of drugs. We focus our drug discovery efforts on those families of targets that are most likely to be affected by small molecule drugs.

 

R-SAT Functional Assay Technologies

 

Our proprietary receptor selection and amplification technology, which we refer to as R-SAT, is a valuable component of our drug discovery platform. R-SAT is a cell-based assay system where genes are transferred to cultured cells. The functional activity of the gene products, or potential drug targets, are then evaluated through signal transduction pathways that lead to cellular growth. The growth signals are reported using marker gene technologies. Thus, effects of drugs on potential drug targets can be efficiently detected as changes in color or fluorescence. R-SAT enables the efficient screening of large compound libraries for identification of new chemistries at given targets, as well as detailed pharmacological testing of compounds at a wide range of targets. We have developed additional proprietary tools that evaluate compound interaction with these targets. One of these technologies measures the physical interaction of GPCRs and RTKs with signaling proteins.

 

Proprietary Receptor Assay Platforms

 

Our scientists have cloned the genes for the majority of the targets in the G-protein coupled receptor, nuclear receptor and tyrosine kinsase gene families. These represent some of the largest families of genes targeted by known drugs. Our R-SAT assay system has enabled the building of functional assays for most of these genes yielding robust assay platforms, which we refer to as GPCR-SAT, NR-SAT and RTK-SAT. We also have developed assays for several additional targets in other relevant gene families.

 

Our Chemistry-Based Discovery Technologies

 

Our drug discovery approach aims to identify small molecules that can serve as chemical starting points, or leads, for optimization efforts providing novel, potent and selective drug candidates for targets that are most likely to be affected by small molecule drugs. To enable our screening operation to identify high quality leads, we have assembled a large proprietary chemical library of diverse compounds. This diverse compound library consists of more than 300,000 small organic molecules. We have also developed proprietary synthetic methods for library construction and lead optimization. In addition, our reference drug library provides us with the opportunity to validate targets and is another key component of our drug discovery platform. This reference drug library includes a wide range of the known central nervous system active drugs.

 

Drug Discovery Opportunities

 

Our proprietary drug discovery platform has generated a wide range of novel chemistries that we believe will continue to provide us with starting points for additional drug programs. We have identified novel chemistries for more than 100 distinct targets. Using these target-specific chemistries, we have established a portfolio of proprietary drug discovery assets and projects in four key therapeutic areas. In each of these areas, we have identified novel chemistries for several different drug targets that we believe play an important role in these major diseases. The following table illustrates examples of targets where we have discovered novel chemistries.

Our discovery projects aim to answer specific scientific questions using relatively-limited synthetic chemistry and biological efforts. When all key criteria have been fulfilled, these earlier-stage discovery projects may be advanced into preclinical programs.

 

Collaboration Agreements

 

We have established three separate collaboration agreements with Allergan, one with Sepracor, and a technology license agreement with Aventis, to leverage our drug discovery platform and related assets and to commercialize selected drug candidates. Our collaborations have included upfront payments at initiation of the collaboration, which may be in the form of an equity investment, research support during the term, milestone payments upon successful completion of specified development objectives, and royalties based upon sales, if any, of drugs developed under the collaboration. Our current agreements are as follows:

 

Allergan

 

In March 2003, we entered into a collaboration agreement with Allergan to discover, develop and commercialize new therapeutics predominantly for ophthalmic indications. The research term is for three years and may be extended by written agreement of the parties. During the research term, the parties will use our target-specific chemistries to explore a range of discovery opportunities. Allergan will have the right to exclusively license chemistry and related assets for up to three drug targets for development and commercialization. Following Allergan’s license of a given target area, we are restricted from conducting competing research in those target areas. Under the agreement, we received an upfront payment and we are entitled to receive research funding and related fees over the three-year research term. The agreement also provides Allergan the option to fund additional research in selected areas. We are also eligible to receive license fees and milestone payments upon the successful achievement of agreed upon clinical and regulatory objectives. Allergan retains the commercialization rights to the drug candidates in the three target areas they exclusively license from us, and we are eligible to receive royalties on future product sales, if any, worldwide. Assuming the successful development of products for each of the three target areas, we could receive up to approximately $60.0 million in aggregate payments under the agreement, excluding product royalties. Through December 31, 2004, we had received a total of $7.9 million pursuant to this collaboration.

 

In July 1999, we entered into a collaboration agreement with Allergan to discover, develop and commercialize selective muscarinic drugs for the treatment of glaucoma based on our compounds. Under this agreement, we provided our chemistry and discovery expertise to enable Allergan to select a compound in November 2003 for development. We granted Allergan exclusive worldwide rights to commercialize products based on this compound for the treatment of ocular disease. As of December 31, 2004, we had received an aggregate of $8.7 million in payments under the agreement, consisting of upfront fees, research funding and milestone payments. We are also eligible to receive additional milestone payments of up to approximately $15.2 million, and would receive royalties on future product sales worldwide, if any. Allergan may terminate this agreement upon 90 days’ notice. However, if terminated, Allergan’s rights to the selected compound would revert to us.

 

In September 1997, we entered into a collaboration agreement with Allergan focused primarily on the discovery and development of new therapeutics for neuropathic pain and ophthalmic indications. This agreement was subsequently amended in conjunction with the execution of the March 2003 collaboration agreement and provides for the continued development of drug candidates for one target area. Pursuant to the agreement, we granted Allergan exclusive worldwide rights to commercialize products resulting from the collaboration. In exchange, we had received an aggregate of $9.5 million in research funding and milestone payments through December 31, 2004. We are also eligible to receive additional milestone payments of up to $11.0 million as well as royalties on future worldwide sales of products, if any, resulting from this collaboration. In connection with the execution of the collaboration agreement in 1997, Allergan made a $6.0 million equity investment in us.

Table of Contents

The general terms of our collaboration agreements with Allergan continue until the later of the expiration of the last to expire patent covering a drug candidate licensed under the collaboration and at least 10 years from the date of first commercial sale of a drug candidate. In addition, each of our Allergan collaboration agreements includes a research term that is shorter but may be renewed by the parties.

 

Sepracor

 

In January 2005, we entered into a collaboration agreement with Sepracor for the development of new drug candidates targeted toward the treatment of central nervous system disorders. Under the agreement, the parties will investigate potential clinical candidates resulting from our preclinical muscarinic program. In connection with the collaboration, Sepracor purchased 1,077,029 shares of our common stock in January 2005 at a price per share of approximately $9.28 for aggregate proceeds of $10 million. Sepracor also agreed to purchase an additional $10 million of our common stock in January 2006 at a 25 percent premium to the 30-day trailing average closing price at that time, subject to specified closing conditions. We will also receive research funding over the three-year research term of the collaboration and, if certain conditions are met, we are eligible to receive milestone payments as well as applicable royalties on worldwide product sales, if any. Assuming the successful development of a single product in the muscarinic program, we may receive up to $40 million in aggregate payments, plus applicable royalties. The agreement also includes an option to select a preclinical compound from our 5-HT2A program for use in combination with LUNESTA, Sepracor’s insomnia drug, for sleep-related indications. In addition, should the collaboration successfully develop a combination product with LUNESTA, we may receive up to approximately $35 million in aggregate payments plus applicable royalties.

 

The general terms of this agreement continue until the later of the expiration of the last to expire patent covering a drug candidate licensed under the collaboration and the earlier of the date a generic version of the product is launched or a specified number of years from the date of the first commercial sale of the product. In addition, this agreement may terminate at the end of the research term if no compound has been selected for advancement. In addition, we or Sepracor can terminate this agreement under certain specified circumstances.

 

The Stanley Medical Research Institute

 

In May 2004, we entered into a development agreement with The Stanley Medical Research Institute, or SMRI, a leading nonprofit organization that supports research on the treatment of schizophrenia. The development term is for three years and may be extended for additional consecutive one-year periods by written agreement of the parties. Under this agreement, we are entitled to receive up to $5 million in funding to support the further development of ACP-104 and, to date, we have received $1 million of this amount. Assuming the successful development and commercialization of ACP-104, we are required to pay to SMRI royalties on product sales of ACP-104 up to a specified level. SMRI may terminate this agreement in selected instances, including if we enter into a strategic alliance covering ACP-104 or do not reasonably progress its development. In connection with this agreement, we issued a $1 million convertible promissory note to SMRI. Upon the closing of our initial public offering on June 2, 2004, the principal and accrued interest under this note automatically converted into 143,914 shares of our common stock at a conversion price equal to the initial public offering price of $7.00 per share.

 

Aventis

 

In July 2002, we entered into an agreement with Aventis under which we have licensed a portion of our technology for their use in a specified area that we are not presently pursuing.

 

Intellectual Property

 

We currently hold eight issued U.S. patents and 24 issued foreign patents. All of these patents originated from us. In addition, we have 46 provisional and utility U.S. patent applications and 116 foreign patent applications.

Patents or other proprietary rights are an essential element of our business. Our strategy is to file patent applications in the United States and any other country that represents an important potential commercial market to us. In addition, we seek to protect our technology, inventions and improvements to inventions that are important to the development of our business. Our patent applications claim proprietary technology, including methods of screening and chemical synthetic methods, novel genomic targets and novel compounds identified using our technology.

 

We also rely upon trade secret rights to protect other technologies that may be used to discover and validate targets and that may be used to identify and develop novel drugs. We protect our trade secrets in part through confidentiality and proprietary information agreements. We are a party to various other license agreements that give us rights to use certain technologies in our research and development.

 

ACP-103

 

Two patents that provide generic coverage for ACP-103 have been issued in the United States. Similar claims for ACP-103 have also been allowed in South Africa. We continue to prosecute patent applications directed to ACP-103 and to methods of treating various diseases using ACP-103, either alone or in combination with other agents, worldwide.

 

ACP-104

 

The chemical structure of ACP-104 is unpatentable, as it has been known and disclosed to the public for many years. We have filed patent applications with claims that will be directed to the use of ACP-104 as a treatment for neuropsychiatric disease, either alone or in combination with various other agents, including ACP-103. We have also filed a provisional patent application covering methods of synthesis of ACP-104 and applications directed to the analogs of ACP-104 and their uses for the treatment of disease. We are aware of an issued patent, not owned by us, that claims the use of ACP-104 for treatment of analgesia.

 

Our Drug Discovery Platform

 

Our core R-SAT technology is protected by three issued U.S. patents and 20 foreign patents.

 

Other Drug Candidates

 

We have two issued U.S. patents and four issued foreign patents with claims for compounds that affect muscarinic receptor activity and we continue to pursue patent applications in this area in the U.S. and in other countries.

 

Competition

 

We face, and will continue to face, intense competition from pharmaceutical and biotechnology companies, as well as numerous academic and research institutions and governmental agencies, both in the United States and abroad. We compete with existing and new products being developed by our competitors. Some of these competitors are pursuing the development of pharmaceuticals that target the same diseases and conditions that our research programs target. In each of our development programs, we intend to complete clinical trials designed to evaluate the potential advantages of our drug candidates as compared to the current standard of care.

 

Even if we and our collaborators are successful in developing our drug candidates, the resulting products would compete with a variety of established drugs in the areas of Parkinson’s disease, schizophrenia, neuropathic pain and glaucoma. For example, our potential product for treatment-induced psychosis in Parkinson’s disease will compete with off-label use of Seroquel, marketed by Astra-Zeneca, and clozapine, a generic drug.

 

42


Table of Contents

Our potential products for the treatment of schizophrenia would compete with Zyprexa, marketed by Eli Lilly, Risperdal, marketed by Johnson & Johnson, Seroquel, and clozapine. Zyprexa is the market leader with worldwide sales of $4.3 billion in 2003, corresponding to an estimated 35 percent market share. While proven effective in schizophrenia and bipolar mania, it produces a variety of adverse events including weight gain, orthostatic hypertension, and other side effects.

 

In the area of neuropathic pain, our potential products would compete with Neurontin and Lyrica (Pregabalin), each marketed by Pfizer, and Cymbalta, marketed by Eli Lilly, as well as with a variety of generic or proprietary opioids. In 2003, Neurontin was the first product to be approved by the FDA for the treatment of neuropathic pain. Neurontin had worldwide sales of approximately $2.7 billion in 2004. Neurontin is only partially effective and is associated with a range of central nervous system related side effects.

 

Our potential products for the treatment of glaucoma would compete with Xalatan, marketed by Pfizer, and Lumigan and Alphagan, marketed by Allergan. Xalatan is the leading drug for glaucoma treatment and had worldwide sales in excess of $1 billion in 2004. It is an effective anti-glaucoma agent but frequently causes an increased pigmentation of the iris that may lead to a change of iris color. Other side effects of Xalatan include blurred vision and burning and stinging sensations in the eye.

 

In addition, the companies described above and other competitors may have a variety of drugs in development or awaiting FDA approval that could reach the market and become established before we have a product to sell. Our competitors may also develop alternative therapies that could further limit the market for any drugs that we may develop. Some of our competitors are using functional genomics technologies or other methods to identify and validate drug targets and to discover novel small molecule drugs. Many of our competitors and their collaborators have significantly greater experience than we do in the following:

 

    identifying and validating targets;

 

    screening compounds against targets;

 

    preclinical and clinical trials of potential pharmaceutical products; and

 

    obtaining FDA and other regulatory clearances.

 

In addition, many of our competitors and their collaborators have substantially greater advantages in the following areas:

 

    capital resources;

 

    research and development resources;

 

    manufacturing capabilities; and

 

    sales and marketing.

 

Smaller companies also may prove to be significant competitors, particularly through proprietary research discoveries and collaborative arrangements with large pharmaceutical and established biotechnology companies. Many of our competitors have products that have been approved or are in advanced development. We face competition from other companies, academic institutions, governmental agencies and other public and private research organizations for collaborative arrangements with pharmaceutical and biotechnology companies, in recruiting and retaining highly qualified scientific and management personnel and for licenses to additional technologies. Our competitors, either alone or with their collaborators, may succeed in developing technologies or drugs that are more effective, safer, and more affordable or more easily administered than ours and may achieve patent protection or commercialize drugs sooner than us. Developments by others may render our drug candidates or our technologies obsolete. Our failure to compete effectively would have a material adverse affect on our business.

Government Regulation

 

The manufacturing and marketing of our potential products and our ongoing research and development activities are subject to extensive regulation by numerous governmental authorities in the United States and other countries. Before marketing in the United States, any drug developed by us must undergo rigorous preclinical testing and clinical trials and an extensive regulatory clearance process implemented by the FDA under the federal Food, Drug, and Cosmetic Act, as amended. The FDA regulates, among other things, the development, testing, manufacture, safety, efficacy, record keeping, labeling, storage, approval, advertising, promotion, sale and distribution of biopharmaceutical products. None of our drug candidates has been approved for sale in the United States or any foreign market. The regulatory review and approval process, which includes preclinical testing and clinical trials of each drug candidate, is lengthy, expensive and uncertain.

 

In the United States, drug candidates are tested in animals until adequate proof of safety is established. Clinical trials for new drug candidates are typically conducted in three sequential phases that may overlap. In Phase I, the initial introduction of the drug candidate into healthy human volunteers, the emphasis is on testing for safety or adverse effects, dosage, tolerance, metabolism, distribution, excretion and clinical pharmacology. Phase II involves studies in a limited patient population to determine the initial efficacy of the pharmaceutical for specific targeted indications, to determine dosage tolerance and optimal dosage and to identify possible adverse side effects and safety risks. Once a compound shows evidence of effectiveness and is found to have an acceptable safety profile in Phase II evaluations, Phase III trials are undertaken to more fully evaluate clinical outcomes. Before commencing clinical investigations in humans, we or our collaborators must submit to the FDA an Investigational New Drug Application, or IND, which must also be approved by the FDA. Regulatory authorities may require additional data before allowing the clinical studies to commence or proceed from one phase to another, and could demand that the studies be discontinued or suspended at any time if there are significant safety issues. We have in the past and may in the future rely on some of our collaborators to file INDs and generally direct the regulatory approval process for many of our potential products. Clinical testing must also meet requirements for institutional review board oversight, informed consent and good clinical practices.

 

Securing FDA approval requires the submission of extensive preclinical and clinical data and supporting information to the FDA for each indication to establish a drug candidate’s safety and efficacy. These data are submitted to the FDA in the form of a New Drug Application, or NDA. The approval process takes many years and requires the expenditure of substantial resources. Information generated in this process is susceptible to varying interpretations that could delay, limit or prevent regulatory approval at any stage of the process. The failure to demonstrate adequately the quality, safety and efficacy of a drug candidate under development would delay or prevent regulatory approval of the drug candidate. We cannot assure you that, even if clinical trials are completed, either our collaborators or we will submit applications for required authorizations to manufacture and/or market potential products or that any such application will be reviewed and approved by the appropriate regulatory authorities in a timely manner, if at all. Under applicable laws and FDA regulations, each NDA submitted for FDA approval is usually given an internal administrative review within 45 to 60 days following submission of the NDA. If deemed complete, the FDA will “file” the NDA, thereby triggering substantive review of the application. The FDA can refuse to file any NDA that it deems incomplete or not properly reviewable. The FDA has established internal goals of six months for priority NDAs and 10 months for regular NDAs. However, the FDA is not legally required to complete its review within these periods and these performance goals may change over time. Moreover, the outcome of the review, even if generally favorable, typically is not an actual approval but an “action letter” that describes additional work that must be done before the NDA can be approved. The FDA’s review of an NDA may involve review and recommendations by an independent FDA advisory committee.

 

Before receiving FDA clearance to market a potential product, we or our collaborators must demonstrate through adequate and well-controlled clinical studies that the potential product is safe and effective on the patient population that will be treated. If regulatory clearance of a potential product is granted, this clearance will be limited to those disease states and conditions for which the product is useful, as demonstrated through clinical studies. Marketing or promoting a drug for an unapproved indication is generally prohibited. Furthermore,

 

44


Table of Contents

clearance may entail ongoing requirements for post-marketing studies. Even if this regulatory clearance is obtained, a marketed product, its manufacturer and its manufacturing facilities are subject to continuing review and periodic inspections by the FDA. Discovery of previously unknown problems with a product, manufacturer or facility may result in restrictions on this product or manufacturer, including labeling changes, costly recalls or withdrawal of the product from the market.

 

Any drug is likely to produce some toxicities or undesirable side effects in animals and in humans when administered at sufficiently high doses and/or for sufficiently long periods of time. Unacceptable toxicities or side effects may occur at any dose level at any time in the course of studies in animals designed to identify unacceptable effects of a drug candidate, known as toxicological studies, or clinical trials of our potential products. The appearance of any unacceptable toxicity or side effect could cause us or regulatory authorities to interrupt, limit, delay or abort the development of any of our drug candidates and could ultimately prevent their clearance by the FDA or foreign regulatory authorities for any or all targeted indications.

 

We and our collaborators and contract manufacturers also are required to comply with the applicable FDA current good manufacturing practice regulations. Good manufacturing practice regulations include requirements relating to quality control and quality assurance as well as the corresponding maintenance of records and documentation. Manufacturing facilities are subject to inspection by the FDA. These facilities must be approved before we can use them in commercial manufacturing of our potential products. We or our collaborators or contract manufacturers may not be able to comply with the applicable good manufacturing practice requirements and other FDA regulatory requirements.

 

Outside of the United States, our ability to market a product is contingent upon receiving a marketing authorization from the appropriate regulatory authorities. The requirements governing the conduct of clinical trials, marketing authorization, pricing and reimbursement vary widely from country to country. At present, foreign marketing authorizations are applied for at a national level, although within the European Community, or EC, registration procedures are available to companies wishing to market a product in more than one EC member state. If the regulatory authority is satisfied that adequate evidence of safety, quality and efficacy has been presented, a marketing authorization will be granted. This foreign regulatory approval process involves all of the risks associated with FDA clearance discussed above.

 

Drugs for Serious or Life-Threatening Illnesses

 

The Federal Food, Drug and Cosmetic Act, as amended, and FDA regulations provide certain mechanisms for the accelerated “Fast Track” approval of potential products intended to treat serious or life-threatening illnesses which have been studied for safety and effectiveness and which demonstrate the potential to address unmet medical needs. The procedures permit early consultation and commitment from the FDA regarding the preclinical and clinical studies necessary to gain marketing approval. Provisions of this regulatory framework also permit, in certain cases, NDAs to be approved on the basis of valid surrogate markers of product effectiveness, thus accelerating the normal approval process. Certain potential products employing our technology might qualify for this accelerated regulatory procedure. Even if the FDA agrees that these potential products qualify for accelerated approval procedures, the FDA may deny approval of our drugs or may require that additional studies be required before approval. The FDA may also require us to perform post-approval, or Phase IV, studies as a condition of early approval. In addition, the FDA may impose restrictions on distribution and/or promotion in connection with any accelerated approval, and may withdraw approval if post-approval studies do not confirm the intended clinical benefit or safety of the potential product.

 

Other U.S. Regulatory Requirements

 

In the United States, the research, manufacturing, distribution, sale, and promotion of drug products are potentially subject to regulation by various federal, state and local authorities in addition to the FDA, including the Centers for Medicare and Medicaid Services (formerly the Health Care Financing Administration), other

 

45


Table of Contents

divisions of the United States Department of Health and Human Services, including, for example, the Office of Inspector General, and state and local governments. For example, sales, marketing and scientific/educational grant programs must comply with the Medicare-Medicaid Anti-Fraud and Abuse Act, as amended, the False Claims Act, also as amended, the privacy provisions of the Health Insurance Portability and Accountability Act, or HIPAA, and similar state laws. Pricing and rebate programs must comply with the Medicaid rebate requirements of the Omnibus Budget Reconciliation Act of 1990, as amended, and the Medicare Prescription Drug Improvement and Modernization Act of 2003. If drug products are made available to authorized users of the Federal Supply Schedule of the General Services Administration, additional laws and requirements apply. All of these activities are also potentially subject to federal and state consumer protection and unfair competition laws.

 

Marketing, Sales and Distribution

 

We currently have no marketing, sales or distribution capabilities. In order to commercialize any of our drug candidates, we must develop these capabilities internally or through collaboration with third parties. In selected therapeutic areas where we feel that our products can be commercialized by a specialty sales force that calls on a limited and focused group of physicians, we plan to commercialize our products. In therapeutic areas that require a large sales force selling to a large and diverse prescribing population, we plan to partner our drug candidates for commercialization.

 

Manufacturing

 

We outsource and plan to continue to outsource manufacturing responsibilities for our existing and future drug candidates for development and commercial purposes. The production of ACP-103 and ACP-104 employs small molecule synthetic organic chemistry procedures that are standard in the pharmaceutical industry. Our collaboration agreements provide for our partners to arrange for the production of our drug candidates for use in clinical trials and potential commercialization.

 

Employees

 

At March 31, 2005, we had 99 full time employees, of whom 39 hold Ph.D. or other advanced degrees. Of our total workforce, 84 are engaged in research and development activities and 15 are engaged in business development, finance and administration. Sixty-seven of our employees are located in the United States and 32 are located in Denmark. None of our employees is represented by a collective bargaining agreement, nor have we experienced work stoppages. We believe that our relations with our employees are good.

 

Facilities

 

Our primary facilities consist of approximately 36,000 square feet of research and office space located in San Diego, California that is leased to us until the fourth quarter of 2005. We have an option to renew the leases for these facilities for one additional period of five years. We also have approximately 21,000 square feet of research and office space located near Copenhagen, Denmark that is leased to us until June 2005. We have entered into a lease for an approximately 30,000 square foot chemistry research and development facility in Malmo, Sweden that is scheduled to commence in June 2005. We believe that our existing facilities are adequate for our current needs. When our leases expire, we may look for additional or alternate space for our operations and we believe that suitable additional or alternative space will be available in the future on commercially reasonable terms.

Each person who is elected or appointed for the first time to be a nonemployee director will be granted an initial grant on the date of his or her election or appointment to the board to purchase 6,500 shares of our common stock.

 

The board resolutions also provide that eligible nonemployee directors receive, on the day following each annual meeting of stockholders, an annual grant to purchase 6,500 shares of our common stock. The annual retainer amount and option grant may be pro rated for a director that joins the board other than at the first meeting of the board following the annual meeting of stockholders. In addition, directors may elect to convert their retainer amounts, in whole or in part, into options under the 2004 Plan with an aggregate exercise price equal to three times the amount elected for conversion.

The exercise price of stock options granted under the 2004 Plan is equal to 100 percent of the fair market value of the common stock on the date of grant. Initial grants (i.e., those made upon a non-employee director’s election to our Board of Directors) vest over three years following the date of grant, and annual grants, including any retainer amounts that are converted, vest at the rate of 1/4th each quarter after the date of grant. In general, the term of stock options granted under the 2004 Plan may not exceed ten years.

 

Unless the terms of an director’s stock option agreement provide for earlier or later termination, if an optionholder’s service relationship with us, or any affiliate of ours, ceases for any reason, the optionholder may exercise any vested options up to three years from cessation of service.

We grant stock options to our executive officers under our 2004 Plan. Prior to our initial public offering, we granted stock options to our executive officers under our 1997 Stock Option Plan, or 1997 Plan. As of March 31, 2005, options to purchase a total of 2,103,643 shares were outstanding under our 1997 Plan and our 2004 Equity Incentive Plan, or 2004 Plan, and a total of 390,281 shares remained available for grant under the 2004 Plan. We stopped making grants under our 1997 Plan following the completion of our initial public offering in June 2004, and the shares remaining available for grant under the 1997 Plan were included in the share reserve for our 2004 Plan.

 

All stock options granted to our executive officers are incentive stock options, to the extent permissible under the Internal Revenue Code. Generally, 25 percent of the shares subject to options vest one year from the date of grant and the remainder of the shares vest in equal monthly installments over the 36 months thereafter, subject to cessation of vesting upon the termination of the optionholder’s continued service to us. Options expire ten years from the date of grant.

Table of Contents

The exercise price per share of each option granted to our executive officers was equal to the fair market value of our common stock on the date of the grant. Prior to the completion of our initial public offering in June 2004, our Board of Directors determined the fair market value of our common stock after considering many factors, including:

 

    the rate of progress and cost of our clinical trials and other research and development activities,

 

    the terms and timing of any collaborative, licensing and other arrangements that we may establish,

 

    the fact that our options involved illiquid securities in a non-public company,

 

    prices of preferred stock issued by us to outside investors in arm’s-length transactions,

 

    the rights, preferences and privileges of our preferred stock over our common stock, and

 

    the likelihood that our common stock would become liquid through an initial public offering, an acquisition of us or another event.

 

Following the completion of our initial public offering, pursuant to the 2004 Plan, the fair market value of our common stock on a given date is deemed to be equal to the closing sales price for such stock as reported on the Nasdaq on the last market trading day prior to such date.

 

The following table provides information regarding grants of options to purchase shares of our common stock to the named executive officers in the fiscal year ended December 31, 2004.

Employee Benefit Plans

 

2004 Equity Incentive Plan

 

In February 2004, our board of directors adopted our 2004 equity incentive plan that became effective upon the closing of our initial public offering. The number of shares authorized for issuance under the 2004 Plan is 945,233 shares of common stock, which includes the 745,233 shares that remained eligible for grant under the 1997 Plan at June 2, 2004, the date of the closing of the Company’s initial public offering. The 2004 Plan share reserve may also be increased by the number of shares, if any, that would otherwise have reverted to the 1997 Plan reserve after June 2, 2004. The 2004 equity incentive plan includes an “evergreen” provision providing that an additional number of shares will automatically be added annually for a period of five years to the shares

 

56


Table of Contents

authorized for issuance under the 2004 equity incentive plan at each annual meeting of stockholders beginning in 2005. The number of shares added each year will be equal to the least of:

 

    three percent of our outstanding common stock as of the record date for the applicable annual meeting;

 

    750,000; or

 

    an amount determined for such year by our board of directors.

 

Shares subject to stock awards that have expired or otherwise terminated without having been exercised in full again become available for grant.

 

The 2004 equity incentive plan permits the grant of options to our directors, officers, other employees and consultants. Options may be either incentive stock options to employees within the meaning of Section 422 of the Internal Revenue Code or nonstatutory stock options. In addition, the 2004 equity incentive plan permits the grant of stock bonuses, rights to purchase restricted stock, stock appreciation rights, phantom stock awards and other stock awards. Except in specified circumstances, no employee may be granted options or stock appreciation rights covering more than 1,000,000 shares of common stock in any calendar year.

 

The 2004 equity incentive plan is administered by our board of directors. Authority to administer the plan may be delegated to a committee or to one or more executive officers. Subject to the limitations set forth in the 2004 equity incentive plan, the plan administrator has the authority to select the eligible persons to whom award grants are to be made, to determine the type of award, to designate the number of shares or other rights to be covered by each award, to determine whether an option is to be an incentive stock option or a nonstatutory stock option, to establish vesting schedules for each award, to specify the exercise price, purchase price or other payment terms of awards and the type of consideration to be paid upon exercise of the awards and, subject to specified restrictions, to specify other terms of awards.

 

The maximum term of any option granted under the 2004 equity incentive plan is ten years. Incentive stock options granted under the 2004 equity incentive plan are generally nontransferable. Nonstatutory stock options are generally nontransferable, although the applicable option agreement may permit some transfers. Options generally expire three months after the termination of an optionholder’s service. However, if an optionholder is permanently disabled, or dies, during his or her service, that person’s options generally may be exercised up to 12 months following disability or up to 18 months following death.

 

The exercise price of options granted under the 2004 equity incentive plan are determined by the board of directors or plan administrator in accordance with the guidelines set forth in the 2004 equity incentive plan. The exercise price of a stock option cannot be less than 100 percent of the fair market value of the common stock on the date of grant. The following methods of payment may be used to apply to the exercise price of the options: cash or, at the discretion of the board of directors, by delivery to us of shares of our common stock, according to a deferred payment arrangement, by “net exercise” or “cashless exercise” or in any other form of legal consideration approved by our board of directors.

 

Options or other awards granted under the 2004 equity incentive plan vest at the rate determined by the board of directors or committee as specified in the option agreement or other applicable award agreement. The terms of any stock bonuses, restricted stock awards, stock appreciation rights, phantom stock awards or other awards granted under the 2004 equity incentive plan will be determined by the board of directors or plan administrator. The purchase price of restricted stock under any restricted stock purchase agreement will be determined by the board of directors or plan administrator. Stock bonuses and restricted stock purchase agreements awarded under the 2004 equity incentive plan will generally be nontransferable, although the applicable award agreement may permit some transfers.

 

Stock appreciation rights under the 2004 equity incentive plan are granted through a stock appreciation right agreement. Each stock appreciation right is denominated in share equivalents. The strike price of each stock

 

57


Table of Contents

appreciation right is determined by our board of directors or the plan administrator. Phantom stock awards under the 2004 equity incentive plan are purchased through phantom stock award agreements. The consideration for a phantom stock award may be payable in any form permitted under applicable laws. Stock appreciation rights may be paid, and phantom stock awards may be settled, in our common stock or in cash or any combination of the two, or any other form of legal consideration approved by our board of directors.

 

In addition, other forms of stock awards, based on our common stock may be granted either alone or in addition to other stock awards under the 2004 equity incentive plan. Our board of directors or the plan administrator has sole and complete authority to determine the persons to whom and the time or times at which such other stock awards will be granted, the number of shares of our common stock to be granted and other conditions of such stock awards.

 

In the event of a corporate transaction amounting to a change of control in our ownership as defined in the 2004 equity incentive plan, all outstanding stock awards under the 2004 equity incentive plan must either be assumed or substituted for by the surviving entity. In the event the surviving entity does not assume or substitute for the stock awards, then the vesting and exercisability of outstanding awards will accelerate prior to the change of control and the awards will terminate to the extent not exercised prior to the change of control.

 

Our board of directors may amend or terminate the 2004 equity incentive plan at any time. Amendments will be submitted for stockholder approval to the extent required by applicable law.

 

At March 31, 2005, we had issued and outstanding under the 2004 stock option plan options to purchase approximately 598,000 shares of common stock and no shares had been purchased upon the exercise of previously issued options. The exercise prices for of these outstanding options ranges from $5.60 per share to $8.11 per share.

 

1997 Stock Option Plan

 

In January 1997, we adopted our 1997 stock option plan. A total of 3,080,000 shares of common stock were authorized for issuance under the 1997 stock option plan, as amended in April 1999, November 2000, March 2002 and June 2003. Shares subject to stock options that have expired or otherwise terminated without having been exercised in full again become available for grant. The 1997 stock option plan permits the grant of options to our directors, officers, other employees and consultants. Options may be either incentive stock options to employees within the meaning of Section 422 of the Internal Revenue Code or nonstatutory stock options. Except in specified circumstances, no person may be granted options covering more than 250,000 shares of common stock in any calendar year.

 

The 1997 stock option plan is administered by our board of directors. The board may delegate the authority to administer the plan to a committee of directors or to one or more executive officers. Subject to the limitations set forth in the plan or limitations created by the board, the administrator has the authority to select the eligible persons to whom option grants are to be made, to designate the number of shares to be covered by each option, to determine whether an option is to be an incentive stock option or a nonstatutory stock option, to establish vesting schedules, to specify the exercise price of options and the type of consideration to be paid upon exercise and, subject to specified restrictions, to specify other terms of option grants under the plan.

 

The maximum term of options granted under the plan is ten years. Options granted under the 1997 stock option plan are generally nontransferable and vest at the rate determined by the administrator as specified in the option agreement.

 

In the event of an acquisition event amounting to a change in control of our ownership as defined in the 1997 stock option plan, our board of directors has the discretion to provide that all outstanding stock options under the plan may be assumed or substituted by the surviving entity. As an alternative or in addition, our board

 

58


Table of Contents

of directors may provide that outstanding options will become exercisable in full at a specified date prior to the change of control and that all unexercised options will terminate immediately prior to the change of control. In addition, options granted to our employees under the 1997 stock option plan require the option holders, in some circumstances, to sell all of their shares and other securities of our company upon request by a group of our major stockholders under our amended and restated stockholders agreement on terms negotiated between those major stockholders and the proposed buyer.

 

Our board of directors may amend or terminate the 1997 stock option plan at any time. Amendments will generally be submitted for stockholder approval to the extent required by applicable law.

 

At March 31, 2005, we had issued and outstanding under the 1997 stock option plan options to purchase approximately 1.5 million shares of common stock and approximately 786,000 shares had been purchased upon the exercise of previously held options. The exercise prices for of these outstanding options ranges from $0.02 per share to $8.00 per share. No options were granted under the 1997 stock option plan following the closing of our initial public offering in June 2004.

 

2004 Employee Stock Purchase Plan

 

In February 2004, we adopted our 2004 employee stock purchase plan, which became effective as of May 26, 2004. A total of 125,000 shares of common stock have been reserved for issuance under the purchase plan. As of March 31, 2005, 18,392 shares had been issued under the 2004 employee stock purchase plan. The purchase plan includes an “evergreen” provision providing that an additional number of shares will automatically be added annually for a period of ten years to the shares authorized for issuance under the purchase plan at our annual meeting of stockholders beginning in 2005. The number of shares added each year will be the least of:

 

    one percent of our outstanding common stock;

 

    150,000; or

 

    an amount expressly determined for such year by our board of directors.

 

The purchase plan is intended to qualify as an employee stock purchase plan within the meaning of Section 423 of the Internal Revenue Code. Under the purchase plan, the board of directors may authorize participation by eligible employees, including executive officers, in periodic offerings following the commencement of the purchase plan. The initial offering under the purchase plan commenced on the effective date of our initial public offering and will continue for two years.

 

Unless otherwise determined by the board of directors, employees are eligible to participate in the purchase plan only if they are employed by us or one of our subsidiaries designated by the board of directors for at least 20 hours per week and are customarily employed for at least five months per calendar year. Employees who participate in an offering may have up to 15 percent of their earnings withheld pursuant to the purchase plan. The amount withheld is then used to purchase shares of common stock on specified dates determined by the board of directors. The price of common stock purchased under the purchase plan will be equal to 85 percent of the lower of the fair market value of the common stock at the commencement date of each offering period or the relevant purchase date. Employees may end their participation in the offering at any time during the offering period, and participation ends automatically upon termination of employment.

 

In the event of a corporate transaction amounting to change of control of ownership as defined in the 2004 employee stock purchase plan, each right to purchase common stock will be assumed or an equivalent right substituted by the successor corporation. In the event that the rights are not assumed or substituted, then all sums collected by payroll deductions will be applied to purchase stock immediately prior to such merger or other transaction. The board of directors has the authority to amend or terminate the purchase plan, provided however, that no such action may adversely affect any outstanding rights to purchase common stock.

401(k) Plan

 

We adopted a 401(k) Plan effective January 1, 1997. All regular employees who are 21 years or older, with the exception of post-doctoral training fellows and graduate student training fellows, are eligible to participate in the plan on the first day of January, April, July or October following their date of hire. These participants may contribute up to 60 percent of their current compensation, subject to a statutorily prescribed annual dollar limit set by the IRS. Participant contributions are held in a trust as required by law. Individual participants may direct the trustee to invest their accounts in authorized investment alternatives. We make matching contributions to the 401(k) Plan on behalf of each participant in an amount equal to 100 percent of the participant’s salary reduction contributions up to five percent of the participant’s annual compensation. In addition, we may make discretionary and special contributions each year, although we have not done so to date. Each participant is fully vested in his or her salary reduction contributions and our matching and special contributions to the 401(k) Plan. We adopted the Safe Harbor Contribution Plan Amendment in January 1999. The 401(k) Plan is intended to qualify under Section 401(a) of the Internal Revenue Code so that contributions to the 401(k) Plan, and income earned on such contributions, are not taxable to participants until withdrawn or distributed from the 401(k) Plan.

In March and May 2003, we sold in a private placement 5,212,962 shares of Series F preferred stock at $5.40 per share for an aggregate purchase price of $28,150,006 in cash. The shares of Series F preferred stock were sold and issued under a Series F preferred stock purchase agreement dated March 27, 2003. We also issued 375,000 shares of Series E preferred stock to then existing holders of preferred stock that participated in the Series F preferred stock financing. Upon the closing of our initial public offering, each share of Series E preferred stock and Series F preferred stock was reclassified into one share of our common stock.

In the first tranche, which closed on January 13, 2005, Sepracor purchased $10 million of our common stock at a 40 percent premium to the average closing sales price for a 30 trading-day period. We issued 1,077,029 shares of our common stock to Sepracor at the closing at a price per share of approximately $9.2848. This transaction made Sepracor a five percent stockholder at that time. The second tranche is scheduled to close in January 2006, subject to customary closing conditions.

PRINCIPAL STOCKHOLDERS

 

Except as otherwise noted, the following table sets forth selected information known to us with respect to beneficial ownership of our common stock at April 20, 2005 by:

 

    each stockholder we know to be the beneficial owner of more than five percent of our common stock;

 

    each of our directors;

 

    each of our named executive officers; and

 

    all of our executive officers and directors as a group.

 

Except where otherwise indicated below, the address of the stockholders listed below is our address, 3911 Sorrento Valley Boulevard, San Diego, California 92121.

 

Applicable percentages are based on 23,338,818 shares outstanding on April 20, 2005, including the 5,277,621 shares issued in the private placement to the selling stockholders. The 1,319,402 shares of common stock issuable upon exercise of the warrants that were issued in the private placement have not been included as they are not exercisable until October 17, 2005. The percentages in the table are adjusted as required by rules promulgated by the SEC, which generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities. In addition, the rules include shares of common stock issuable pursuant to the exercise of stock options or warrants that are either immediately exercisable or exercisable on June 19, 2005, which is 60 days after April 20, 2005. These shares are deemed to be outstanding and beneficially owned by the person holding those options or warrants for the purpose of computing the percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person. Certain of the options in this table are exercisable at any time but, if exercised, are subject to a lapsing right of repurchase until the options are fully vested. The table is based upon information supplied by our officers, directors and principal stockholders and a review of Schedules 13D and 13G, if any, filed with the SEC.

DESCRIPTION OF CAPITAL STOCK

 

Our authorized capital stock consists of 75,000,000 shares of common stock, $0.0001 par value per share, and 5,000,000 shares of preferred stock, $0.0001 par value per share. At April 20, 2005, there were 23,338,818 outstanding shares of common stock held of record by approximately 109 stockholders, warrants to purchase 1,393,475 shares of common stock, and options to purchase 2,115,893 shares of common stock.

 

Common Stock

 

Subject to preferences that may apply to shares of preferred stock outstanding at the time, the holders of outstanding shares of common stock are entitled to receive dividends out of assets legally available at such times and in such amounts as our board of directors may from time to time determine. Each stockholder is entitled to one vote for each share of common stock held on all matters submitted to a vote of stockholders. Cumulative voting for the election of directors is not provided for in our certificate of incorporation, which means that the holders of a majority of the shares voted can elect all of the directors then standing for election. The common stock is not entitled to preemptive rights and is not subject to conversion or redemption. In the event of our liquidation, dissolution or winding up, the common stock is entitled to share in all assets remaining after payment of liabilities and liquidation preferences of outstanding shares of preferred stock. Each outstanding share of common stock is fully paid and nonassessable.

 

Preferred Stock

 

Our board of directors has the authority, without further action by the stockholders, to issue up to 5,000,000 shares of preferred stock in one or more series and to fix the designations, powers, preferences, privileges, and relative participating, optional or special rights and the qualifications, limitations or restrictions thereof, including dividend rights, conversion rights, voting rights, terms of redemption and liquidation preferences, any or all of which may be greater than the rights of the common stock. Our board of directors, without stockholder approval, can issue preferred stock with voting, conversion or other rights that could adversely affect the voting power and other rights of the holders of common stock. Preferred stock could thus be issued quickly with terms calculated to delay or prevent a change of control or make removal of management more difficult. The issuance of preferred stock may have the effect of decreasing the market price of the common stock, and may adversely affect the voting and other rights of the holders of common stock. At present, there are no shares of preferred stock outstanding and we have no plans to issue any of the preferred stock.

 

Warrants

 

We have outstanding warrants to purchase an aggregate of 74,073 shares of common stock at an exercise price of $8.10 per share. These warrants expire in May 2012 or on the occurrence of specified events, whichever occurs first. We also have outstanding warrants to purchase an aggregate of 1,319,402 shares of common stock at an exercise price of $8.148 per share, which were issued in connection with a private placement that closed on April 20, 2005. The shares of our common stock issuable upon exercise of these warrants are covered by this prospectus however, these warrants are not exercisable until October 17, 2005, and expire on April 19, 2010 or on the occurrence of specified events, whichever occurs first.

 

Anti-Takeover Provisions

 

Delaware Law

 

We are governed by the provisions of Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits a public Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. A “business combination” includes mergers, asset sales or other transactions resulting in a financial benefit to the stockholder.

 

66


Table of Contents

An “interested stockholder” is a person who, together with affiliates and associates, owns, or within three years, did own, 15 percent or more of the corporation’s outstanding voting stock. This provision could delay, discourage or prohibit transactions not approved in advance by the board of directors, such as takeover attempts that might result in a premium over the market price of the common stock.

 

Charter and Bylaw Provisions

 

Our certificate of incorporation and bylaws contain provisions that could discourage potential takeover attempts and make more difficult attempts by stockholders to change management. Our certificate of incorporation provides that stockholders may not take action by written consent but may only act at a stockholders’ meeting, and that special meetings of our stockholders may only be called by the Chairman of our board of directors or a majority of our board of directors. In addition, the terms of office of our board of directors are divided into three classes as described in “Management—Board Composition.”

 

Registration Rights

 

Under the terms of our amended and restated stockholders agreement, the holders of approximately nine million shares of our common stock will have the right to demand that we register their shares, subject to limitations, under the Securities Act. In addition, these holders and the holders of warrants to purchase an aggregate of 74,073 shares of our common stock are entitled, subject to limitations, to require us to include their shares in future registration statements that we may file for our own account or for the account of other stockholders. We also granted demand and piggy-back registration rights to Sepracor.

 

We have filed the registration statement that contains this prospectus pursuant to the registration rights granted to the selling stockholders. They do not have the right to require us to file another registration statement.

 

We are generally required to bear all of the expenses of these registrations, except underwriting discounts and commissions. Registration of any of the shares of common stock entitled to these registration rights would result in the shares becoming freely tradable without restriction under the Securities Act following their sale pursuant to a registration statement. The registration rights with respect to the shares held by any party to the amended and restated stockholders agreement will terminate if the stockholder holds less than one percent of the then outstanding shares of common stock and the stockholder’s shares are entitled to be resold without restriction under Rule 144 promulgated under the Securities Act.

 

Transfer Agent and Registrar

 

The Transfer Agent and Registrar for our common stock is Mellon Investor Services. The Transfer Agent and Registrar’s address is 400 South Hope Street, Los Angeles, California 90071.

SELLING STOCKHOLDERS

 

On April 15, 2005, we entered into a securities purchase agreement with the selling stockholders named below, pursuant to which we sold an aggregate of 5,277,621 shares of our common stock and issued warrants to purchase up to 1,319,402 shares of our common stock in a private placement transaction. This prospectus covers the offer and sale by the selling stockholders of up to the total number of shares of common stock issued to the selling stockholders pursuant to the securities purchase agreement plus the total number of shares of common stock issuable upon exercise of the warrants issued to the selling stockholders pursuant to the securities purchase agreement. Throughout this prospectus, when we refer to the shares of our common stock being registered on behalf of the selling stockholders, we are referring to the shares and the warrant shares, collectively, unless otherwise indicated. The warrants issued to the selling stockholders are exercisable at any time in whole or in part beginning October 17, 2005 and ending April 19, 2010 at an exercise price of $8.148 per share.

 

We are registering the above-referenced shares to permit each of the selling stockholders and their pledgees, donees, transferees or other successors-in-interest that receive their shares after the date of this prospectus to resell the shares in the manner contemplated under the “Plan of Distribution.”

 

The selling stockholders may sell some, all or none of their shares. We do not know how long the selling stockholders will hold the shares before selling them. We currently have no agreements, arrangements or understandings with the selling stockholders regarding the sale of any of the shares other than the securities purchase agreement. The shares offered by this prospectus may be offered from time to time by the selling stockholders, although the warrant shares will not be eligible to be offered pursuant to this prospectus until the related warrants become exercisable.

 

The following table sets forth the name of each selling stockholder, the number of shares owned, including warrant shares that are not yet owned, by each of the respective selling stockholders, the number of shares that may be offered under this prospectus and the number of shares of our common stock to be owned by the selling stockholders after this offering is completed, assuming that all offered shares are sold as contemplated herein. The number of shares in the column “Number of Shares Being Offered” represents all of the shares that a selling stockholder may offer under this prospectus.

 

Except as otherwise disclosed in this prospectus, none of the selling stockholders has, or within the past three fiscal years has had, any position, office or other material relationship with us.

 

Ownership is based upon information provided by each respective selling stockholder, Schedules 13D and 13G and other public documents filed with the SEC. Although the warrants held by the selling stockholders are not exercisable until October 17, 2005, the shares of common stock issuable upon exercise of the warrants held by the selling stockholders are included in the table below since those shares of common stock are being offered in this prospectus. The percentages of shares owned after the offering are based on 23,338,818 shares of our common stock outstanding as of April 20, 2005, which includes the outstanding shares of common stock offered by this prospectus but excludes all warrant shares since the related warrants are not currently exercisable and are not exercisable within 60 days from the date hereof.

Table of Contents

The selling stockholders may have sold or transferred, in transactions exempt from the registration requirements of the Securities Act of 1933, some or all of their shares since the date on which the information in the table is presented.

PLAN OF DISTRIBUTION

 

The selling stockholders, which as used herein includes donees, pledgees, transferees or other successors-in-interest selling shares of common stock or interests in shares of common stock received after the date of this prospectus from a selling stockholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of common stock or interests in shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.

 

The selling stockholders may use any one or more of the following methods when disposing of shares or interests therein:

 

    on The Nasdaq National Market (or any other exchange on which the shares may be listed);

 

    on the over-the-counter market;

 

    ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

 

    block trades in which the broker-dealer will attempt to sell the shares as agent, but may position and resell a portion of the block as principal to facilitate the transaction;

 

    purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

 

    an exchange distribution in accordance with the rules of the applicable exchange;

 

    privately negotiated transactions;

 

    short sales;

 

    through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

 

    broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;

 

    a combination of any such methods of sale; and

 

    any other method permitted pursuant to applicable law.

 

The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b) or under any applicable provision of the Securities Act amending the list of selling stockholders to include the pledgee, transferee or other successors-in-interest as selling stockholders under this prospectus. The selling stockholders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus. To the extent required, this prospectus may be amended or supplemented from time to time to describe a specific plan of distribution.

 

In connection with the sale of shares of our common stock or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may, in turn, engage in short sales of shares of common stock in the course of hedging the positions they assume. The selling stockholders may also sell shares of our common stock short and deliver these securities to close out their short positions, or loan or pledge shares of common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

Table of Contents

The aggregate proceeds to the selling stockholders from the sale of the shares of common stock offered by them will be the purchase price of the shares less discounts or commissions, if any. Each of the selling stockholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made directly or through agents. We will not receive any of the proceeds from this offering. Upon any exercise of the warrants by payment of cash, however, we will receive the exercise price of the warrants.

 

The selling stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the Securities Act, provided that they meet the criteria and conform to the requirements of that rule.

 

The selling stockholders and any underwriters, broker-dealers or agents that participate in the sale of the shares of common stock or interests therein may be “underwriters” within the meaning of Section 2(11) of the Securities Act. Any discounts, commissions, concessions or profit they earn on any resale of the shares may be underwriting discounts and commissions under the Securities Act. Selling stockholders who are “underwriters” within the meaning of Section 2(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act. The selling stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act.

 

We will bear substantially all of the costs, expenses and fees in connection with the registration of the shares of common stock, other than any commissions, discounts or other fees payable to broker-dealers in connection with any sale of shares, which will be borne by the selling stockholder selling such shares of common stock. We have agreed to indemnify the selling stockholders against certain liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the shares offered by this prospectus.

 

In order to comply with the securities laws of some states, if applicable, the shares of common stock may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the shares may not be sold unless it has been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

 

We have advised the selling stockholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares of our common stock in the market and to the activities of the selling stockholders. These rules may limit the timing of purchases and sales of the shares by such selling stockholders.

 

We will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the selling stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act.

 

We have agreed with each selling stockholder to keep the registration statement of which this prospectus constitutes a part effective with respect to its shares of our common stock until the earlier of (1) April 20, 2007, (2) the date on which all shares purchased from us by such selling stockholder in the private placement may be sold pursuant to Rule 144 of the Securities Act without volume limitations, and (3) such time as all of such selling stockholder’s shares covered by this prospectus have been disposed of pursuant to and in accordance with the registration statement.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

 

To the Board of Directors and Stockholders of

ACADIA Pharmaceuticals Inc.

 

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, of stockholders’ equity (deficit) and comprehensive income (loss) and of cash flows present fairly, in all material respects, the financial position of ACADIA Pharmaceuticals Inc. and its subsidiary at December 31, 2003 and 2004, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2004 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

 

1. Organization and Nature of Operations

 

ACADIA Pharmaceuticals Inc. (the “Company”), was originally incorporated in Vermont on July 16, 1993 as Receptor Technologies, Inc. The Company reincorporated in Delaware in 1997. ACADIA is focused on the discovery and development of small molecule drugs for the treatment of central nervous system disorders. ACADIA Pharmaceuticals A/S, a wholly owned subsidiary of the Company based near Copenhagen, Denmark, was established in 1997 to conduct the Company’s chemistry research operations.

 

The Company has not been profitable and has generated substantial operating losses since its inception. The Company’s operations are subject to certain risks and uncertainties, including those associated with the history of operating losses and risk of continued losses, early stage of development, dependence on the outcome of clinical trials, and dependence on regulatory approval to sell products. At December 31, 2004, the Company’s accumulated losses were approximately $94.3 million. The Company expects to increase its operating expenses over the next several years as it expands its research and development activities. Accordingly, the Company will require additional financing in the future to fund its operations. The Company does not know whether additional financing will be available when needed, or if it will be available on favorable terms. If adequate funds are not available or are not available on acceptable terms, the Company’s ability to fund its operations, take advantage of opportunities, develop drug candidates and technologies or otherwise respond to competitive pressures could be significantly limited.

 

2. Summary of Significant Accounting Policies

 

Significant accounting policies followed in the preparation of these financial statements are as follows:

 

Principles of Consolidation

 

The accompanying consolidated financial statements include the accounts of the Company and ACADIA Pharmaceuticals A/S, its wholly owned subsidiary. All intercompany accounts and transactions have been eliminated in consolidation.

 

Cash and Cash Equivalents

 

The Company considers all highly liquid investments with an initial maturity date at the date of purchase of three months or less to be cash equivalents.

 

Investment Securities

 

Investment securities are considered to be available-for-sale and are carried at fair value. Unrealized gains and losses, if any, are reported as a separate component of stockholders’ equity (deficit). The cost of investment securities classified as available-for-sale is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and accretion are included in interest income. Realized gains and losses are also included in interest income. The cost of securities sold is based on the specific identification method.

 

Fair Value of Financial Instruments

 

For financial instruments consisting of cash and cash equivalents, accounts payable and accrued expenses included in the Company’s financial statements, the carrying amounts are reasonable estimates of fair value due to their short maturities. Estimated fair values for investment securities, which are separately disclosed elsewhere, are based on quoted market prices for the same or similar instruments. Based on borrowing rates currently available to the Company, the carrying value of the equipment financing lines approximate fair value.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

Property and Equipment

 

Property and equipment are recorded at cost and depreciated over their estimated useful lives (generally three to ten years) using the straight line method. Leasehold improvements are amortized over the shorter of their estimated useful lives or the term of the respective leases by use of the straight line method. Maintenance and repair costs are expensed as incurred. When assets are retired or sold, the assets and accumulated depreciation are removed from the respective accounts and any gain or loss is recognized.

 

Revenues

 

The Company recognizes revenues in accordance with Securities and Exchange Commission Staff Accounting Bulletin, or SAB, No. 104, Revenue Recognition. SAB No. 104 requires that four basic criteria must be met before revenue can be recognized: persuasive evidence of an arrangement exists; delivery has occurred or services have been rendered; the fee is fixed and determinable; and collectibility is reasonably assured. The Company’s revenues are primarily related to its collaboration agreements, and such agreements provide for various types of payments to the Company, including research funding, upfront payments, future milestone payments, and royalties.

 

Upfront, nonrefundable payments under collaboration agreements are recognized ratably over the term of the agreement. Payments for research funding are recognized as revenues as the related research activities are performed. The Company’s collaborations do not require scientific achievement as a performance obligation, and amounts received under the agreements are nonrefundable. Revenues from nonrefundable milestones are recognized when earned, provided that (i) the milestone event is substantive and its achievability was not reasonably assured at the inception of the agreement and (ii) the Company does not have ongoing performance obligations. Any amounts received under the agreements in advance of performance are recorded as deferred revenue. Revenues from licenses of our technology are generally recognized at the inception of the license term. When arrangements contain extended payment terms, revenues are recognized upon the receipt of the payment. None of the revenues recognized to date are refundable even if the related research activities are not successful.

 

Research and Development Costs

 

Research and development costs are expensed as incurred. Research and development costs include costs associated with services provided by contract organizations for preclinical development, manufacturing of clinical materials, and clinical trials. In the case of clinical trials, a portion of the estimated cost normally relates to the projected cost to treat a patient in the trials and this cost is recognized over the estimated term of the study based on the number of patients enrolled in the trial on an ongoing basis, beginning with patient enrollment. The Company determines the total cost of a given study based on the terms of the related contract. The Company accrues for costs incurred as the services are being provided by monitoring the status of the trial and the invoices received from its external service providers. As actual costs become known, the Company adjusts its accruals. Certain research and development projects are funded under agreements with collaboration partners, and the costs related to these activities are included in research and development expense. The charges to collaboration partners are based upon negotiated rates for full-time equivalent scientists of the Company, and such rates are intended to approximate the Company’s anticipated cost.

 

Concentrations of Risk

 

Financial instruments which potentially subject the Company to concentrations of credit risk principally consist of cash, cash equivalents and investment securities. The Company invests its excess cash primarily in marketable debt securities of government agencies, corporations and financial institutions with strong credit ratings. The Company has adopted an investment policy that includes guidelines relative to diversification and maturities to maintain safety and liquidity.

During the years ended December 31, 2004, 2003 and 2002, revenue from two customers comprised 100 percent, 99 percent and 88 percent of revenues, respectively, of which 98 percent, 67 percent and 58 percent, respectively, were from Allergan, a related party. At December 31, 2004 and 2003, deferred revenue from Allergan was $1,320,300 and $1,320,000, respectively.

 

Foreign Currency Translation

 

The functional currency of ACADIA Pharmaceuticals A/S is the local currency. Accordingly, assets and liabilities of this entity are translated at the current exchange rate at the balance sheet date and historical rates for equity. Revenue and expense components are translated at weighted average exchange rates in effect during the period. Gains and losses resulting from foreign currency translation are included as a component of stockholders’ equity (deficit). At December 31, 2004 and 2003, the balance within accumulated and other comprehensive income from foreign currency translation was $380,300 and $416,400, respectively. Other foreign currency transaction gains and losses are included in the results of operations and, to date, have not been significant.

 

Stock-Based Compensation

 

The Company measures compensation expense for its employee stock-based compensation plans using the intrinsic value method and provides pro forma disclosures of net income (loss) as if a fair value method had been applied in measuring compensation expense. Accordingly, compensation cost for stock awards is measured as the excess, if any, of the fair value of the Company’s common stock at the date of grant over the amount an employee must pay to acquire the stock. Compensation cost is amortized over the related vesting periods using an accelerated method. Accrued compensation costs for unvested awards that are forfeited are reversed against compensation expense or unearned stock-based compensation, as appropriate, in the period of forfeiture.

 

Stock-based awards issued to nonemployees are accounted for using a fair value method and are remeasured to fair value at each period end until the earlier of the date that performance by the nonemployee is complete or a performance commitment has been obtained. The fair value of each award is estimated using the Black-Scholes option pricing model.

 

Pro forma information regarding net income (loss) has been determined as if the Company had accounted for its employee stock options and its employee stock purchase plan under the fair value methodology.

 

The value of each employee stock option granted is estimated on the grant date under the fair value method using the Black-Scholes option pricing model. Prior to the initial public trading of the Company’s stock on May 27, 2004, the value of each employee stock option grant was estimated on the date of grant using the minimum value method. Under the minimum value method, a volatility factor of 0.0 percent is assumed. The following assumptions were used for the employee stock purchase plan, which became effective on May 26, 2004: dividend yield of 0.0 percent; volatility of 50.0 percent; risk-free interest rate of 3.0 percent; and expected life (in years) of 0.5. The weighted average fair value of employee stock purchase rights granted during the year ended December 31, 2004 was approximately $2.01. The following weighted average assumptions were used for employee stock options:

Income Taxes

 

Current income tax expense or benefit represents the amount of income taxes expected to be payable or refundable for the current year. A deferred income tax asset or liability is computed for the expected future impact of differences between the financial reporting and income tax bases of assets and liabilities and for the expected future tax benefit to be derived from tax credits and loss carryforwards. Deferred income tax expense or benefit represents the net change during the year in the deferred income tax asset or liability. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized.

 

Use of Estimates

 

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.

 

Long Lived Assets

 

The Company assesses potential impairments to its long lived assets when there is evidence that events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss is recognized when the estimated undiscounted cash flows expected to result from the use of the asset and its eventual disposition is less than its carrying amount. The amount of the impairment loss, if any, will generally be measured as the difference between the net book value of the assets and their estimated fair values. No such impairment losses have been recorded by the Company.

Comprehensive Income (Loss)

 

All components of comprehensive income (loss), including net income (loss), are reported in the financial statements in the period in which they are recognized. Comprehensive income (loss) is defined as the change in equity (net assets) of a business enterprise during a period from transactions and other events and circumstances from nonowner sources. Accordingly, in addition to reporting net income (loss) under the current rules, the Company is required to display the impact of any fluctuations in its foreign currency translation adjustments and any unrealized gains or losses on its investment securities as components of comprehensive income (loss) and to display an amount representing total comprehensive income (loss) for each period.

 

Net Income (Loss) Per Common Share

 

Basic earnings (loss) per common share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings (loss) per common share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period increased to include potential dilutive common shares that were outstanding during the period. The dilutive effect of outstanding stock options and warrants is reflected, when dilutive, in diluted earnings (loss) per common share by application of the treasury stock method.

 

The Company has excluded all outstanding stock options and warrants from the calculation of diluted net loss per common share because all such securities are antidilutive for all periods presented. The total number of potential common shares excluded from the calculation of diluted net loss per common share, prior to application of the treasury stock method for options and warrants, was 1,992,222, 1,546,148 and 1,003,060 for the years ended December 31, 2004, 2003 and 2002, respectively. The Company computes its net income (loss) per share using the two-class method; therefore, the Company’s income (loss) is allocated between the common stockholders and the preferred stockholders based on their respective rights to share in dividends. For the years ended December 31, 2003 and 2002, the method by which the Company allocated net income (loss) to the preferred stock was based on the number of preferred shares outstanding compared to the total combined preferred and common shares outstanding at the end of the year. The remaining net income (loss) was allocated to common stockholders. The amounts allocated to each class were then divided by the weighted average number of shares of each class outstanding during the year to determine income (loss) per share. Upon the closing of the Company’s initial public offering on June 2, 2004, all outstanding preferred stock was reclassified or converted into common stock. For the year ended December 31, 2004, the Company allocated net income (loss) through the date of the initial public offering to the preferred stock based on the number of preferred shares outstanding as of June 2, 2004 compared to the total combined preferred and common shares outstanding as of that date. The remaining income (loss) for this period was allocated to the common stock, along with any income (loss) for the remainder of the year. The amount allocated to the common stock was divided by the weighted average number of common shares outstanding during 2004 to determine income (loss) per common share. The amount allocated to the preferred stock for 2004 was divided by the weighted average number of preferred shares outstanding from the beginning of the year through June 2, 2004, when all of the shares of preferred stock were reclassified or converted into common stock, to calculate income (loss) per preferred share through the date of the initial public offering.

 

The basic and diluted net loss per common share amounts for the year ended December 31, 2004, presented in the consolidated statements of operations, include the effect, on a weighted average basis, of the 5.0 million shares of common stock issued in the Company’s initial public offering that closed on June 2, 2004 and the approximately 9.9 million shares of common stock issued upon conversion or reclassification of the Company’s preferred stock in conjunction with the closing of the initial public offering.

Recently Issued Accounting Standards

 

In December 2004, the FASB issued SFAS No. 123 (revised 2004), Share-Based Payment (“SFAS 123(R)”). This Statement is a revision of SFAS No. 123, Accounting for Stock-Based Compensation, and supersedes APB Opinion No. 25, Accounting for Stock Issued to Employees, and its related implementation guidance. SFAS 123(R) requires that compensation cost relating to share-based payment transactions be recognized in financial statements. That cost will be measured based on the fair value of the equity or liability instruments issued. This statement will be effective beginning with the Company’s first quarter of 2006. The Company is currently evaluating the requirements of SFAS 123(R) and has not yet fully determined the impact on its consolidated financial statements.

 

In March 2004, the FASB issued EITF Issue No. 03-01, The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments (“EITF 03-01”), which provides new guidance for assessing impairment losses on investments. Additionally, EITF 03-01 includes new disclosure requirements for investments that are deemed to be temporarily impaired. In September, 2004 the FASB delayed the accounting provisions of EITF 03-01; however the disclosure requirements remain effective for annual periods ending after June 15, 2004. The Company will evaluate the impact of EITF 03-01 once the final guidance is issued.

 

3. Investment Securities

 

Investment securities are comprised entirely of marketable debt securities of corporations and financial institutions. The fair value of available-for-sale securities by contractual maturity is as follows:

 

     December 31,

     2004

   2003

Corporate securities due within one year

   $ 25,554,800    $ 15,522,300

Corporate securities due after one year

     2,070,900      5,383,600
    

  

     $ 27,625,700    $ 20,905,900
    

  

 

The fair value of investment securities at December 31, 2004 was lower than historical cost and, therefore, an unrealized loss of $65,900 is included in accumulated other comprehensive income in stockholders’ equity. The fair value of investment securities at December 31, 2003 was higher than historical cost, thus an unrealized gain of $7,700 is included in accumulated other comprehensive income in stockholders’ deficit.

5. Long-Term Debt

 

The Company has entered into equipment financing agreements that were used by the Company to finance $6.7 million of capital expenditures. The agreements provide for equal monthly installments to be paid over a three to four year period, with interest at rates ranging from 7.93 percent to 9.58 percent per annum. Outstanding borrowings under these agreements are collateralized by the related equipment. At December 31, 2004 and 2003, the Company had $1,970,100 and $2,260,200, respectively, in outstanding borrowings under these agreements. The Company was in compliance with certain required financial covenants and conditions at December 31, 2004 and 2003.

 

In May 2002, the Company issued a secured promissory note for $5,000,000. At December 31, 2004 and 2003, the Company had balances of $560,400 and $2,606,100, respectively, outstanding under this promissory note. The note payable accrues interest at a rate of 10.73 percent with monthly interest only payments through August 2002, followed by monthly principal and interest payments through March 2005. The note payable is collateralized by substantially all personal property of the Company, excluding its intellectual property. In connection with the note payable, the Company issued to the lender warrants to purchase shares of its convertible preferred stock, which are now exercisable for shares of the Company’s common stock. The fair value of the warrant was deducted from the total proceeds resulting in a debt discount of $304,000 (Note 7), which is being amortized to interest expense over the term of the note payable.

 

At December 31, 2004, future payments under the Company’s long-term debt are as follows:

6. Collaborative Research and Licensing Agreements

 

In March 2003, the Company entered into a three year collaboration agreement with Allergan, Inc. to discover, develop and commercialize new therapeutics predominantly for ophthalmic indications. Under the agreement, Allergan will have the exclusive right to license chemistry and related assets for up to three drug targets. The Company received an upfront payment and is entitled to receive research funding and additional fees over the three-year term. The Company is also eligible to receive license fees and milestone payments as well as royalties on future product sales worldwide, if any. Revenue recognized under this agreement during the years ended December 31, 2004 and 2003 totaled $3.9 million and $2.7 million, respectively.

 

In July 1999, the Company entered into a collaboration agreement with Allergan to discover, develop and commercialize drugs for glaucoma based on the Company’s compounds. Under the agreement, the Company provided its drug discovery expertise to enable the selection by Allergan of a drug candidate for development and commercialization. Allergan was granted worldwide rights to products based on this compound for the treatment of ocular disease. As of December 31, 2004, the Company had received an aggregate of $8.7 million in payments under the agreement, consisting of upfront fees, research and development funding and milestone payments. In addition, the Company is eligible to receive additional milestone payments as well as royalties on future product sales worldwide, if any. Revenue recognized under this agreement totaled $165,000, $1.8 million and $1.9 million during the years ended December 31, 2004, 2003 and 2002, respectively.

 

In September 1997, the Company entered into a collaboration agreement with Allergan focused primarily on the discovery and development of new therapeutics for neuropathic pain and ophthalmic indications. This agreement was subsequently amended in conjunction with the execution of the March 2003 collaboration agreement and provides for the continued development of drug candidates for one target area. Pursuant to the 1997 agreement, the Company granted Allergan exclusive worldwide rights to commercialize products resulting from the collaboration. In exchange, the Company received an aggregate of $9.5 million in research funding and milestone payments through December 31, 2004. The Company is also eligible to receive additional milestone payments as well as royalties on future worldwide sales of products, if any. Revenue recognized under this agreement totaled $500,000, $463,100 and $1.7 million during the years ended December 31, 2004, 2003 and 2002, respectively. In connection with the execution of the collaboration agreement in 1997, Allergan made a $6.0 million equity investment in the Company.

 

In May 2004, the Company entered into a development agreement with The Stanley Medical Research Institute, or SMRI. The development term is for three years and may be extended for additional one-year periods by written agreement of the parties. Under this agreement, the Company is entitled to receive up to $5 million in funding to support the further development of one of the Company’s drug candidates for the treatment of schizophrenia. Assuming the successful development and commercialization of this drug candidate, the Company is required to pay to SMRI royalties on product sales up to a specified level. SMRI may terminate this agreement in selected instances, including if the Company enters into a strategic alliance covering the drug candidate or does not reasonably progress its development. Upon signing this agreement, the Company also received $1 million from SMRI in exchange for a convertible promissory note issued to SMRI bearing interest at 9% per annum (the “SMRI Note”). Upon the closing of the Company’s initial public offering on June 2, 2004, the SMRI Note and accrued interest automatically converted into 143,914 shares of the Company’s common stock at the initial public offering price of $7.00 per share. As of December 31, 2004, no revenues have been recognized under this development agreement.

 

In July 2002, the Company entered into an agreement with Aventis under which the Company granted Aventis a license to utilize certain of the Company’s technology for a specified use. The agreement provided for an initial payment and annual payments thereafter. The agreement terminates upon expiration of the Company’s

On May 25, 2004, the Company effected a 1-for-2 reverse stock split of the outstanding preferred stock and common stock. The accompanying financial statements give retroactive effect to the 1-for-2 reverse stock split for all periods presented.

 

Initial Public Offering

 

On June 2, 2004, the Company completed the initial public offering of 5.0 million shares of its common stock for proceeds of $31.1 million, net of underwriting discounts and commissions and offering expenses.

 

Convertible Preferred Stock

 

Each outstanding share of the Company’s Series A, B, D, E and F preferred stock was reclassified and each share of the Company’s Series C preferred stock was converted into one share of its common stock upon the closing of the initial public offering on June 2, 2004.

 

A summary of the Company’s preferred stock as of December 31, 2003 is as follows:

 

     Shares
Authorized


   Shares Issued and
Outstanding


Series A

   2,372,548    1,186,271

Series B

   738,384    369,190

Series C

   1,000,000    500,000

     21,169,067    9,900,913
    
  

 

Prior to the reclassification or conversion of the Company’s preferred stock upon the completion of its initial public offering, the holders of the preferred stock had rights and preferences with respect to conversion, voting, dividends, liquidation and rights of first refusal, among other things. Other than registration rights with respect to the common shares now held by the preferred stockholders, all rights and preferences relating to the preferred stock under the Company’s Certificate of Incorporation expired upon the reclassification or conversion into common stock and other rights of the preferred stock terminated upon the closing of the initial public offering on June 2, 2004. The preferred stock was considered mezzanine equity for presentation in the December 31, 2003 consolidated balance sheet.

Warrants

 

At December 31, 2004, the Company had outstanding warrants to purchase an aggregate of 74,073 shares of its common stock. Each of the warrants has an exercise price of $8.10 per share and expires in May 2012. The warrants were issued in connection with a secured promissory note in 2002 (Note 5). The fair value of the warrants at the time of grant was determined by management to be $304,000 based upon the application of the Black-Scholes option pricing model using the following assumptions: contractual life of ten years, risk free interest rate of 4.9%, volatility of 80% and expected dividend yield of zero. The fair value of the warrants was recorded as a debt discount.

 

Stock Option Plans

 

The 1997 stock option plan (the “1997 Plan”), as amended, provided for the grant of incentive stock options and nonqualified stock options to employees, officers, directors, consultants and advisors of the Company representing the right to purchase up to an aggregate of 3,080,000 shares of common stock. The exercise price of each option grant was set at the fair market value for the Company’s common stock as determined by the Company’s Board of Directors and each option’s maximum term was ten years. Options granted under the 1997 Plan generally vest over a four-year period. The 1997 Plan permitted grants to certain employees allowing those employees to early exercise their options for restricted shares of the Company’s common stock that were subject to the original vesting terms of the option. Restricted shares are generally subject to a repurchase option in favor of the Company that is exercisable upon termination of the employment of the optionee at an amount per share equal to the purchase price of the restricted shares. For financial reporting purposes, these options are not considered exercised until the repurchase feature lapses. Therefore, the amount of cash received by the Company for the purchase of restricted shares is included as a liability until the repurchase feature lapses. Furthermore, for financial reporting purposes restricted shares subject to repurchase are excluded from the calculation of basic earnings per share (and only included in the computation of diluted earnings per share to the extent their effect is dilutive). No restricted shares subject to repurchase were outstanding prior to January 2004. At December 31, 2004, 143,720 restricted shares were subject to repurchase by the Company and $159,400 was recorded as an accrued expense. Upon the closing of the initial public offering on June 2, 2004, all shares that remained eligible for grant under the 1997 Plan were transferred to the 2004 Equity Incentive Plan. Therefore, at December 31, 2004, no shares remain available for new grants under the 1997 Plan but shares may still be issued thereunder upon the exercise of options granted prior to the closing of the initial public offering on June 2, 2004.

 

The 2004 Equity Incentive Plan (the “2004 Plan”) was approved by the stockholders in May 2004 and became effective upon the closing of the initial public offering on June 2, 2004. The 2004 Plan permits the grant of options to directors, officers, other employees and consultants. In addition, the 2004 Plan permits the grant of stock bonuses, rights to purchase restricted stock, stock and other stock awards. The number of shares authorized for issuance under the 2004 Plan is 945,233 shares of common stock, which includes the 745,233 shares that remained eligible for grant under the 1997 Plan at June 2, 2004, the date of the closing of the Company’s initial public offering. The 2004 Plan share reserve may also be increased by the number of shares, if any, that would otherwise have reverted to the 1997 Plan reserve after June 2, 2004. The 2004 Plan includes an “evergreen” provision providing that an additional number of shares will automatically be added to the shares authorized for issuance at each annual meeting of stockholders for a period of five years beginning in 2005. At December 31, 2004, 796,467 shares of common stock were available for new grants under the 2004 Plan.

During the years ended December 31, 2004 and 2003, in connection with the grant of various stock options to employees, the Company recorded unearned stock-based compensation, net of forfeitures, of $1,478,400 and $3,049,600, respectively, representing the difference between the exercise price and the estimated market value of the Company’s common stock on the date such stock options were granted. Unearned stock-based

compensation is included as a component of stockholders’ deficit and is being amortized to expense over the vesting period of the options in accordance with FASB Interpretation No. 28, Accounting for Stock Appreciation Rights and Other Variable Stock Option or Award Plans. During the years ended December 31, 2004, 2003 and 2002, the Company recorded amortization of unearned stock-based compensation expense of $2,306,000, $1,306,400 and $1,252,800, respectively.

 

During the years ended December 31, 2004, 2003 and 2002, in connection with the grant of stock options to consultants, the Company recorded expense of $49,800, $86,100 and a credit of $90,200, respectively. For purposes of determining this compensation expense, the fair value of each option grant is estimated on the measurement date using the Black-Scholes option pricing model with the following assumptions used for each of the years ended December 31, 2004, 2003 and 2002: dividend yield of 0.0 percent; volatility of 100 percent; and contractual life of ten years for all periods. Risk free interest rates of 4 percent, 4 percent and 6 percent were assumed for the years ended December 31, 2004, 2003 and 2002, respectively.

 

Employee Stock Purchase Plan

 

The Company’s 2004 Employee Stock Purchase Plan (the “Purchase Plan”) was approved by the stockholders in May 2004 and became effective upon the closing of the initial public offering on June 2, 2004. A total of 125,000 shares of common stock have been reserved for issuance under the Purchase Plan. The Purchase Plan includes an “evergreen” provision providing that an additional number of shares will automatically be added to the shares authorized for issuance at each annual meeting of stockholders for a period of ten years beginning in 2005. Eligible employees who elect to participate in an offering under the Purchase Plan may have up to 15% of their earnings withheld, subject to certain limitations, to purchase shares of common stock pursuant to the Purchase Plan. The price of common stock purchased under the Purchase Plan is equal to 85% of the lower of the fair market value of the common stock at the commencement date of each offering period or the relevant purchase date. During the year ended December 31, 2004, 18,392 shares of common stock were issued under the Purchase Plan.

 

Common Stock Reserved For Future Issuance

 

At December 31, 2004, 1,773,875 and 74,073 shares of common stock were reserved for issuance upon the exercise of stock options and warrants, respectively.

 

8. 401(k) Plan

 

Effective January 1997, the Company established a deferred compensation plan (the “401(k) Plan”) pursuant to Section 401(k) of the Internal Revenue Code of 1986, as amended (the “Code”), whereby substantially all employees are eligible to contribute up to 60 percent of their pretax earnings, not to exceed amounts allowed under the Code. The Company makes contributions to the 401(k) Plan equal to 100 percent of each employee’s pretax contributions up to 5 percent of his or her eligible compensation. The Company’s total contributions to the 401(k) Plan were $219,600, $204,700, $214,100, for the years ended December 31, 2004, 2003 and 2002, respectively.

 

9. Income Taxes

 

At December 31, 2004, the Company had both federal and state net operating loss carryforwards of approximately $70,600,000 and $14,700,000, respectively, which will begin to expire in 2013 and 2007, respectively. The Company has $1,650,000 of federal research and development credit carryforwards that will

begin to expire in 2012. In addition, the Company has $1,749,000 of state research and development credit carryforwards that have no expiration date. The Company also has foreign net operating loss carryforwards of approximately $4,900,000 that will begin to expire in 2005. In certain circumstances, as specified in the Code, an ownership change of fifty percent or more by certain combinations of the Company’s stockholders during any three-year period could result in an annual limitation on the Company’s ability to utilize portions of the domestic net operating loss and research and development credit carryforwards.

The Company is party to a civil action brought by a former employee whose employment was terminated by the Company. The Company believes that this lawsuit is without merit and intends to vigorously defend itself. While the amount of damages sought has not been specified, it is the opinion of the Company, after consultation with its outside legal counsel regarding the claims specified in the complaint, that the resolution of this matter will not have a material impact on the Company’s business, results of operations, or financial condition. However, as with most litigation, the ultimate resolution of this matter is subject to uncertainties.

 

11. Subsequent Event

 

On January 10, 2005, the Company entered into a collaboration agreement with Sepracor Inc. (“Sepracor”) for the development of new drug candidates targeted toward the treatment of central nervous system disorders. In connection with this collaboration, Sepracor purchased 1,077,029 shares of the Company’s common stock for $10 million, a price of approximately $9.28 per share, representing a 40% premium to the 30-day trailing average closing price. Sepracor also agreed to purchase up to $10 million of ACADIA common stock at a 25 percent premium to the 30-day trailing average closing price on the one-year anniversary date of the collaboration, subject to customary closing conditions. These stock purchases, in the aggregate, shall not exceed 19.99 percent of the Company’s outstanding common stock after giving effect to the second purchase. The Company will receive research funding from Sepracor over a three-year term and, if certain conditions are met, is eligible to receive milestone payments as well as royalties on future product sales worldwide, if any. The agreement also includes an option to select a preclinical compound from the Company for use in combination with LUNESTA, Sepracor’s insomnia drug, for sleep-related indications. Should this option be exercised, the Company is eligible to receive additional license and milestone payments, as well as royalties on future product sales worldwide, if any.

13. Subsequent Event (Unaudited)

 

On April 20, 2005, the Company completed a private placement in which it raised net proceeds of approximately $34 million through the sale, at a price of $6.82125 per share, of 5,277,621 shares of its common stock and warrants to purchase 1,319,402 shares of its common stock. The warrants have an exercise price of $8.148 per share and become exercisable on October 17, 2005 and will expire on April 19, 2010, unless earlier terminated. Pursuant to the terms of the private placement documents, the Company has filed a registration statement with the SEC to register for resale the shares of common stock sold in the private placement and the shares of common stock issuable upon the exercise of the warrants.

Item 14. Indemnification of Directors and Officers

 

Section 102 of the Delaware General Corporation Law allows a corporation to eliminate the personal liability of directors of a corporation to the corporation or its stockholders for monetary damages for a breach of fiduciary duty as a director, except where the director breached his duty of loyalty, failed to act in good faith, engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase in violation of Delaware corporate law or obtained an improper personal benefit.

 

Section 145 of the Delaware General Corporation Law provides that a corporation has the power to indemnify a director, officer, employee or agent of the corporation and certain other persons serving at the request of the corporation in related capacities against amounts paid and expenses incurred in connection with an action or proceeding to which he is or is threatened to be made a party by reason of such position, if such person shall have acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interest of the corporation, and, in any criminal proceeding, if such person had no reasonable cause to believe his conduct was unlawful; provided that, in the case of actions brought by or in the right of the corporation, no indemnification shall be made with respect to any matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the adjudicating court determines that such indemnification is proper under the circumstances.

 

The Registrant’s amended and restated certificate of incorporation and bylaws includes provisions that indemnify directors and officers of the corporation for actions taken in such capacity, if the actions were taken in good faith and in a manner reasonably believed to be in the best interests of the corporation and, in a criminal proceeding, the director or officer had no reasonable cause to believe that his conduct was unlawful. A director or officer who is successful in defending a claim will be indemnified for all expenses incurred in connection with his defense. The Registrant has entered into indemnification agreements with its officers and directors that require the Registrant to indemnify such persons against any and all expenses (including attorneys’ fees), witness fees, damages, judgments, fines, settlements and other amounts incurred in connection with any action, suit or proceeding, whether actual or threatened, to which any such person may be made a party by reason of the fact that such person is or was or at any time becomes a director, an officer or an employee of the Registrant or any of its affiliated enterprises, provided that such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to our best interest and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful.

 

We maintain directors and officers insurance providing indemnification for certain of our directors, officers, affiliates, partners and employees for certain liabilities.

Since January 1, 2002, the Registrant has sold and issued the following unregistered securities:

 

1. On May 31, 2002, the Registrant borrowed $5,000,000 from GATX Ventures Inc. under a secured promissory note issued pursuant to a venture loan and security agreement. In connection with such loan, the Registrant issued warrants to purchase an aggregate of 74,073 shares of its Series F Preferred Stock. The warrants have an exercise price of $8.10 per share and expire on May 31, 2012. The warrants are exercisable for 74,073 shares of the Registrant’s common stock. The fair value of the warrants at the time of grant was determined by management to be $304,000.

 

2. On March 27, 2003 and May 30, 2003, the Registrant issued an aggregate of 5,212,962 shares of its Series F preferred stock to 15 accredited investors for an aggregate purchase price of $28,150,000. The shares of Series F preferred stock were sold were issued under a Series F preferred stock purchase agreement dated March 27, 2003. The Registrant also issued 375,000 shares of Series E preferred stock in connection with its Series F preferred stock financing. Upon the closing of the Registrant’s initial public offering in June 2004, each share of Series E preferred stock and Series F preferred stock was reclassified into one share of the Registrant’s common stock.

 

3. Prior to its initial public offering, the Registrant granted options to purchase an aggregate of 2,334,768 shares of its common stock, including options subsequently cancelled that then became available for new option grants, to directors, employees and consultants under the Registrant’s 1997 stock option plan. The exercise prices for such options ranged from $0.02 to $8.00 per share. As of June 2, 2004, the date of the closing of the Registrant’s initial public offering, the Registrant had issued an aggregate of 666,178 shares of common stock upon the exercise of stock options under the Registrant’s 1997 stock option plan. Shares issued after June 2, 2004, upon the exercise of options that were outstanding under the 1997 stock option plan on June 2, 2004 were issued pursuant to the Registrant’s registration statement on Form S-8, No. 333-115956.

 

4. On May 3, 2004, the Registrant issued to The Stanley Medical Research Institute a convertible promissory note in the aggregate principal amount of $1 million. The note bore interest at 9% per annum. The principal and accrued interest under the note were automatically converted into 143,914 shares of the Registrant’s common stock upon the closing of the initial public offering at a conversion price equal to $7.00, which was the price per share in the initial public offering.

 

5. On January 13, 2005, Sepracor Inc. purchased $10 million of the Registrant’s common stock at a 40 percent premium to the average closing sales price for a 30 trading-day period. Registrant issued 1,077,029 shares of its common stock to Sepracor at the closing at a price per share of approximately $9.2848.

 

6. On April 20, 2005, the Registrant completed a private placement of the shares of its common stock and warrants to purchase shares of its common stock to 12 qualified institutional buyers and two accredited investors. The Registrant sold 5,277,621 shares of its common stock at a price of $6.82125 per share. The Registrant also issued warrants to purchase 1,319,402 shares of its common stock with an exercise price of $8.148 per share. The purchasers in the transaction are the selling stockholders listed in the prospectus filed as a part of this registration statement. The aggregate offering price of the shares of common stock sold was approximately $36 million and the aggregate placement agent commissions were approximately $1.6 million. Banc of America Securities LLC, Piper Jaffray & Co. and JMP Securities LLC acted as Registrant’s placement agents for this transaction.

 

The offers, sales and issuances of these securities were deemed to be exempt from registration under the Securities Act in reliance on Section 4(2) of the Securities Act, and/or Regulation D promulgated thereunder, or Rule 701 promulgated under Section 3(b) of the Securities Act, as transactions by an issuer not involving a public offering or transactions under compensatory benefit plans and contracts relating to compensation as provided under such Rule 701. The recipients of securities in each such transaction represented their intention to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof and appropriate legends were affixed to the share certificates issued in such transactions. All recipients had adequate access, through employment or other relationships, to information about the Registrant.

Schedules have been omitted because the information required to be set forth therein is not applicable or is shown in the financial statements or notes thereto.

 

Item 17. Undertakings

 

The undersigned Registrant hereby undertakes:

 

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

 

(i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

 

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.

 

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

 

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

 

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

 

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to provisions described in Item 14 above or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
