ASTRAZENECA PROVIDES UPDATE ON PHASE III TRIAL OF SELUMETINIB IN NON-SMALL CELL LUNG CANCER
Selumetinib did not meet trial endpoint of
progression-free survival in KRASm NSCLC patients
AstraZeneca today announced results from the Phase III SELECT-1 trial of the MEK 1/2 inhibitor, selumetinib, in combination with docetaxel chemotherapy as 2nd-line treatment in patients with KRAS mutation-positive (KRASm) locally-advanced or metastatic non-small cell lung cancer (NSCLC).
The results showed that the trial did not meet its primary endpoint of progression-free survival (PFS), and selumetinib did not have a significant effect on overall survival (OS). The adverse event profiles for selumetinib and docetaxel were consistent with those seen previously.
Sean Bohen, Executive Vice President, Global Medicines Development and Chief Medical Officer at AstraZeneca, said: "A randomised Phase II trial showed promising activity of selumetinib in combination with docetaxel in patients with KRAS mutation-positive lung cancer. It is disappointing for patients that these results have not been confirmed in Phase III. We expect to present
data at a forthcoming medical meeting. We remain committed to further developing treatments in the lung cancer setting, such as our immunotherapy combinations and targeted EGFR treatments."
SELECT-1 is an international trial with 510 randomised patients in over 200 centres. Patients received either selumetinib (75mg, orally, twice daily) or placebo in combination with docetaxel (intravenously, 75mg/m2, on day one of every 21-day cycle).
Selumetinib is being explored as a treatment option in registration-enabling studies in patients with differentiated thyroid cancer where the treatment received Orphan Drug Designation, and patients with neurofibromatosis type 1, a genetic disorder that causes tumours to grow along nerve tissue.1
About KRASm non-small cell lung cancer
KRAS is one of the most common genetic mutations in NSCLC, and is found in 30% of patients.2 Adenocarcinomas make up the majority of cases with KRAS mutations, which are less common in squamous cell NSCLC.2,3
KRAS mutations are associated with activation of the RAS-ERK signalling pathway, which drives tumour growth.3
About selumetinib (AZD6244, ARRY-142886)
Selumetinib is an oral, potent and highly selective MEK 1/2 inhibitor. MEK 1/2 are critical components of the RAS-ERK pathway, activation of which is implicated in driving cancer growth and progression, including in patients with KRASm NSCLC.4,5
AstraZeneca acquired exclusive worldwide rights to selumetinib from Array BioPharma Inc. (NASDAQ: ARRY) in 2003.
In May 2016, selumetinib was granted Orphan Drug Designation by the US Food and Drug Administration (FDA) for adjuvant treatment of patients with stage III or IV differentiated thyroid cancer (DTC), and AstraZeneca is committed to exploring its full potential, including in Phase III trials in patients with DTC
and in a US National Cancer Institute-sponsored Phase II registration trial in patients with paediatric neurofibromatosis type 1.
About SELECT-1
SELECT-1 (NCT01933932) is a Phase III, double-blind, randomised, placebo-controlled trial. It is designed to assess the efficacy and safety of selumetinib (75 mg twice daily, given orally on a continuous schedule) in combination with docetaxel (75 mg/m2 intravenously
on day 1 of every 21-day cycle), compared with matched placebo in combination with docetaxel (same schedule) in 510 patients receiving 2nd-line treatment for KRASm locally advanced or metastatic NSCLC (stage IIIB-IV), confirmed by central testing of tumour tissue using the cobas® KRAS Mutation Test (Roche Molecular Systems).3
The primary endpoint is PFS, and secondary endpoints include OS, objective response rate (ORR), duration of response (DoR), and safety and tolerability.3
About AstraZeneca in Oncology
AstraZeneca has a deep-rooted heritage in Oncology and offers a quickly growing portfolio of new medicines that has the potential to transform patients' lives and the Company's future. With at least 6 new medicines to be launched between 2014 and 2020 and a broad pipeline of small molecules and biologics in development, we are committed to advance
New Oncology as one of AstraZeneca's six Growth Platforms focused on lung, ovarian, breast and blood cancers. In addition to our core capabilities, we actively pursue innovative partnerships and investments that accelerate the delivery of our strategy, as illustrated by our investment in Acerta Pharma in haematology.
By harnessing the power of four scientific platforms -- immuno-oncology, the genetic drivers of cancer and resistance, DNA damage response and antibody drug conjugates -- and by championing the development of personalised combinations, AstraZeneca has the vision to redefine cancer treatment and one day eliminate cancer as a cause of death.
About AstraZeneca
AstraZeneca is a global, science-led biopharmaceutical company that focuses on the discovery, development and commercialisation of prescription medicines, primarily for the treatment of diseases in three main therapy areas - Respiratory and Autoimmunity, Cardiovascular and Metabolic
Diseases, and Oncology. The Company is also active in inflammation, infection and neuroscience through numerous collaborations. AstraZeneca operates in over 100 countries and its innovative medicines are used by millions of patients worldwide. For more information please visit: www.astrazeneca.com.
