LYNPARZA® (olaparib) in Combination with Bevacizumab Approved in the EU as First-Line Maintenance Treatment for HRD-Positive Advanced Ovarian Cancer
AstraZeneca and Merck announced EU approval for LYNPARZA combined with bevacizumab for maintenance treatment of advanced ovarian cancer patients with HRD-positive status. This decision is based on the PAOLA-1 Phase 3 trial, showing a 67% reduction in disease progression risk when compared to bevacizumab alone, with median progression-free survival rising to 37.2 months. Despite serious adverse reactions reported, including fatigue and anemia, the approval underscores the importance of HRD testing in treatment selection. AstraZeneca will receive $25 million from Merck following this collaboration.

KENILWORTH, N.J.--(BUSINESS WIRE)--AstraZeneca and Merck, known as MSD outside the United States and Canada, today announced that LYNPARZA in combination with bevacizumab has been approved in the European Union (EU) for the maintenance treatment of adult patients with advanced (FIGO stages III and IV) high-grade epithelial ovarian, fallopian tube or primary peritoneal cancer who are in response (complete or partial) following completion of first-line platinum-based chemotherapy in combination with bevacizumab and whose cancer is associated with homologous recombination deficiency (HRD)-positive status defined by either a breast cancer susceptibility gene 1/2 (BRCA1/2) mutation and/or genomic instability.
The approval by the European Commission was based on a biomarker subgroup analysis of the PAOLA-1 Phase 3 trial showing LYNPARZA in combination with bevacizumab maintenance treatment demonstrated progression-free survival (PFS) benefit versus bevacizumab alone for patients with HRD-positive advanced ovarian cancer. It follows the recommendation for approval by the Committee for Medicinal Products for Human Use of the European Medicines Agency in September 2020.
Dave Fredrickson, executive vice president, oncology business unit, AstraZeneca, said, “Half of all newly diagnosed patients with advanced ovarian cancer have HRD-positive tumors. Women treated with LYNPARZA in combination with bevacizumab in the PAOLA-1 Phase 3 trial lived progression free for a median of more than three years, showing that HRD testing should be an essential component of clinical diagnosis. HRD status can help physicians select a personalized first-line treatment regimen for patients to substantially delay relapse in this devastating disease.”
Dr. Roy Baynes, senior vice president and head of global clinical development, chief medical officer, Merck Research Laboratories, said, “Biomarker testing has rapidly enhanced our understanding of how PARP inhibition can help target this devastating disease. The EU approval reinforces that HRD-positive tumors represent a distinct subset of advanced ovarian cancer and HRD testing is critical for women in this setting.”
The PAOLA-1 trial showed that LYNPARZA in combination with bevacizumab maintenance treatment reduced the risk of disease progression or death by

About PAOLA-1
PAOLA-1 is a double-blind Phase 3 trial testing the efficacy and safety of LYNPARZA added to standard-of-care bevacizumab versus bevacizumab alone, as a first-line maintenance treatment for newly diagnosed advanced (FIGO stages III and IV) high-grade serous or endometroid ovarian, fallopian tube or peritoneal cancer patients who had a complete or partial response to first-line treatment with platinum-based chemotherapy and bevacizumab.
PAOLA-1 is an ENGOT (European Network of Gynaecological Oncological Trial groups) trial, sponsored by ARCAGY Research (Association de Recherche sur les CAncers dont GYnécologiques) on behalf of GINECO (Groupe d’Investigateurs National des Etudes des Cancers Ovariens et du sein). ARCAGY-GINECO is an academic group specializing in clinical and translational research in patients’ cancers and a member of the GCIG (Gynecologic Cancer InterGroup).
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 Ovarian Cancer
In 2018, there were nearly 68,000 new cases of ovarian cancer diagnosed in Europe and around 45,000 deaths. Approximately
About Homologous Recombination Deficiency
HRD encompasses a wide range of genetic abnormalities, including BRCA mutations, that can be detected using tests. As the BRCA gene drives DNA repair via homologous recombination, mutation of this gene leads to homologous recombination deficiency thereby interfering with normal cell DNA repair mechanisms. BRCA mutations are just one of many HRDs which confer sensitivity to PARP inhibitors including LYNPARZA.
