AstraZeneca and Merck (NYSE: MRK), known as MSD outside the United States and Canada, today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion, recommending LYNPARZA for approval as monotherapy for the maintenance treatment of adult patients with germline BRCA1/2 mutations (gBRCAm) who have metastatic adenocarcinoma of the pancreas and have not progressed after a minimum of 16 weeks of platinum treatment within a first-line chemotherapy regimen.
The CHMP based its positive opinion on results from the Phase 3 POLO trial, which were previously published in The New England Journal of Medicine.
The trial demonstrated LYNPARZA nearly doubled the time patients with gBRCAm metastatic pancreatic cancer lived without disease progression or death to a median of 7.4 months vs. 3.8 months on placebo (HR 0.53 [95% CI 0.35-0.82] p=0.004).
The safety and tolerability profile of LYNPARZA in the POLO trial was consistent with previous trials. The most common adverse reactions (ARs) ≥10% were fatigue/asthenia (60%), nausea (45%), abdominal pain (34%), diarrhea (29%), anemia (27%), decreased appetite (25%), constipation (23%), vomiting (20%), back pain (19%), arthralgia (15%), rash (15%), thrombocytopenia (14%), dyspnea (13%), neutropenia (12%), nasopharyngitis (12%), dysgeusia (11%), and stomatitis (10%). The most common ≥ Grade 3 ARs were anemia (11%), fatigue/asthenia (5%), decreased appetite (3%), abdominal pain (2%), vomiting (1%) and arthralgia (1%). Among patients taking LYNPARZA, dose interruptions due to an AR of any grade occurred in 35% and dose reductions due to an AR occurred in 17%. Discontinuation due to ARs occurred in 6% of patients receiving LYNPARZA.
Dr. José Baselga, executive vice president, oncology R&D, AstraZeneca, said, “Patients with advanced pancreatic cancer have seen limited treatment advances over the last few decades. We are now one step closer to potentially bringing the first targeted medicine to certain biomarker-selected patients with advanced pancreatic cancer in the EU.”
Dr. Roy Baynes, senior vice president and head of global clinical development, chief medical officer, Merck Research Laboratories, said, “A pancreatic cancer diagnosis is devastating, and we are committed to research that aims to change the prognosis for patients. The POLO trial demonstrated that treatment with LYNPARZA extended time without disease progression in certain patients with advanced pancreatic cancer – we are hopeful that we will be able to bring this treatment to patients in the EU soon.”
LYNPARZA is approved in the U.S. as a first line maintenance treatment for patients with gBRCAm metastatic pancreatic cancer whose disease has not progressed on at least 16 weeks of a first-line platinum-based chemotherapy regimen.
IMPORTANT SAFETY INFORMATION
CONTRAINDICATIONS
There are no contraindications for LYNPARZA.
WARNINGS AND PRECAUTIONS
Myelodysplastic Syndrome/Acute Myeloid Leukemia (MDS/AML): Occurred in <1.5% of patients exposed to LYNPARZA monotherapy, and the majority of events had a fatal outcome. The duration of therapy in patients who developed secondary MDS/AML varied from <6 months to >2 years. All of these patients had previous chemotherapy with platinum agents and/or other DNA-damaging agents, including radiotherapy, and some also had a history of more than one primary malignancy or of bone marrow dysplasia.
Do not start LYNPARZA until patients have recovered from hematological toxicity caused by previous chemotherapy (≤Grade 1). Monitor complete blood count for cytopenia at baseline and monthly thereafter for clinically significant changes during treatment. For prolonged hematological toxicities, interrupt LYNPARZA and monitor blood count weekly until recovery.
If the levels have not recovered to Grade 1 or less after 4 weeks, refer the patient to a hematologist for further investigations, including bone marrow analysis and blood sample for cytogenetics. Discontinue LYNPARZA if MDS/AML is confirmed.
Pneumonitis: Occurred in <1% of patients exposed to LYNPARZA, and some cases were fatal. If patients present with new or worsening respiratory symptoms such as dyspnea, cough, and fever, or a radiological abnormality occurs, interrupt LYNPARZA treatment and initiate prompt investigation. Discontinue LYNPARZA if pneumonitis is confirmed and treat patient appropriately.
Embryo-Fetal Toxicity: Based on its mechanism of action and findings in animals, LYNPARZA can cause fetal harm. A pregnancy test is recommended for females of reproductive potential prior to initiating treatment.
Females
Advise females of reproductive potential of the potential risk to a fetus and to use effective contraception during treatment and for 6 months following the last dose.
Males
Advise male patients with female partners of reproductive potential or who are pregnant to use effective contraception during treatment and for 3 months following the last dose of LYNPARZA and to not donate sperm during this time.
Venous Thromboembolic Events: Including pulmonary embolism, occurred in 7% of patients with metastatic castration-resistant prostate cancer who received LYNPARZA plus androgen deprivation therapy (ADT) compared to 3.1% of patients receiving enzalutamide or abiraterone plus ADT in the PROfound study. Patients receiving LYNPARZA and ADT had a 6% incidence of pulmonary embolism compared to 0.8% of patients treated with ADT plus either enzalutamide or abiraterone. Monitor patients for signs and symptoms of venous thrombosis and pulmonary embolism, and treat as medically appropriate, which may include long-term anticoagulation as clinically indicated.

About POLO
POLO is a Phase 3 randomized, double-blinded, placebo-controlled, multi-center trial of LYNPARZA tablets (300 mg twice daily) as maintenance monotherapy vs. placebo. The trial randomized 154 patients with gBRCAm metastatic pancreatic cancer whose disease had not progressed on first-line platinum-based chemotherapy. Patients were randomized (3:2) to receive LYNPARZA or placebo until disease progression. The primary endpoint was progression-free survival and key secondary endpoints included overall survival, time to second disease progression, overall response rate and health-related quality of life. Phase 3 POLO results were published in The New England Journal of Medicine and presented at the 2019 American Society of Clinical Oncology Annual Meeting.
About LYNPARZA® (olaparib)
LYNPARZA is a first-in-class PARP inhibitor and the first targeted treatment to potentially exploit DNA damage response (DDR) pathway deficiencies, such as BRCA mutations, to preferentially kill cancer cells. Inhibition of PARP with LYNPARZA leads to the trapping of PARP bound to DNA single-strand breaks, stalling of replication forks, their collapse and the generation of DNA double-strand breaks and cancer cell death. LYNPARZA is being tested in a range of tumor types with defects and dependencies in the DDR.
LYNPARZA, which is being jointly developed and commercialized by AstraZeneca and Merck, has a broad and advanced clinical trial development program, and AstraZeneca and Merck are working together to understand how it may affect multiple PARP-dependent tumors as a monotherapy and in combination across multiple cancer types.
About Pancreatic Cancer
Pancreatic cancer is the 12th most commonly occurring cancer worldwide and the 7th leading cause of cancer death globally. The disease has the lowest survival rate of the most common cancers, and is the only major cancer with a single-digit five-year survival rate (2-9%) in nearly every country. There were approximately 460,000 new cases worldwide in 2018. As there are often no symptoms, or symptoms may be non-specific in the early stages, it is most commonly diagnosed at an incurable stage. Around 80% of pancreatic cancer patients are diagnosed when the disease has metastasized and for these, the average survival is less than a year. Despite advances in treatment, few improvements have been made in diagnosis and treatment over the decades. Current treatment is surgery (for which approximately only 10-20% of patients are eligible), chemotherapy and radiotherapy, highlighting a critical unmet medical need for more effective treatment options.12
About BRCA Mutations
BRCA1 and BRCA2 are human genes that produce proteins responsible for repairing damaged DNA and play an important role in maintaining the genetic stability of cells. When either of these genes is mutated, or altered, such that its protein product either is not made or does not function correctly, DNA damage may not be repaired properly, and cells become unstable. As a result, cells are more likely to develop additional genetic alterations that can lead to cancer.
