AstraZeneca Announces Lynparza Approved in the U.S, as 1st-line Maintenance Treatment With Bevacizumab for HED-positive Advanced Ovarian Cancer

AstraZeneca (NYSE: AZN) and MSD Inc., Kenilworth, N.J., US (NYSE: MRK) today announced that Lynparza (olaparib) in combination with bevacizumab has been approved in the US for the maintenance treatment of adult patients with advanced epithelial ovarian, fallop

AstraZeneca (NYSE: AZN) and MSD Inc., Kenilworth, N.J., US (NYSE: MRK) today announced that Lynparza (olaparib) in combination with bevacizumab has been approved in the US for the maintenance treatment of adult patients with advanced epithelial ovarian, fallopian tube or primary peritoneal cancer who are in complete or partial response to 1st-line platinum-based chemotherapy and whose cancer is associated with homologous recombination deficiency (HRD) positive status defined by either a deleterious or suspected deleterious BRCA mutation, and/or genomic instability. Patients will be selected for therapy based on an FDA-approved companion diagnostic test.
 
The approval by the US Food and Drug Administration (FDA) was based on a biomarker subgroup analysis of the Phase III PAOLA-1 trial which showed that Lynparza in combination with bevacizumab maintenance treatment reduced the risk of disease progression or death by 67% (equal to a hazard ratio of 0.33). The addition of Lynparza improved progression-free survival (PFS) to a median of 37.2 months versus 17.7 months with bevacizumab alone in patients with HRD-positive advanced ovarian cancer.
 
Approximately one in two women with advanced ovarian cancer has an HRD-positive tumour. For patients with advanced ovarian cancer, the primary aim of 1st-line treatment is to delay disease progression for as long as possible with the intent to achieve long-term remission.
 
Isabelle Ray-Coquard, principal investigator of the PAOLA-1 trial and medical oncologist, Centre Léon Bérard and President of the GINECO group, said: "Ovarian cancer is a devastating disease. The magnitude of benefit in HRD-positive patients in the PAOLA-1 trial is impactful. The combination of Lynparza and bevacizumab now provides women with HRD-positive advanced ovarian cancer with a new standard of care and I look forward to seeing this translate into clinical practice."
 
Dave Fredrickson, Executive Vice President, Oncology Business Unit, said: "This approval represents another milestone for Lynparza in patients with ovarian cancer. The median progression-free survival of more than three years offers new hope for more women to delay relapse in this difficult-to-treat disease. These results further establish that HRD-positive is a distinct subset of ovarian cancer, and HRD testing is now a critical component for the diagnosis and tailoring of treatment for women with advanced ovarian cancer."
 
Roy Baynes, Senior Vice President and Head of Global Clinical Development, Chief Medical Officer, MSD Research Laboratories, said: "Advances in understanding the role of biomarkers and PARP inhibition have fundamentally changed how physicians treat this aggressive type of cancer. Today's approval based on the PAOLA-1 trial highlights the importance of HRD testing at diagnosis to identify those who may benefit from Lynparza in combination with bevacizumab as a 1st-line maintenance treatment."
 
The full results from the Phase III PAOLA-1 trial were published in The New England Journal of Medicine.
 
Regulatory reviews are currently underway in the EU, Japan and other countries for Lynparza based on results from the PAOLA-1 trial. As part of a broad development programme, Lynparza is being tested as a monotherapy and in combination across multiple tumour types including as a potential adjuvant treatment of patients with germline BRCA-mutated high-risk HER2-negative primary breast cancer in the Phase III OlympiA trial.
 
Financial considerations
Following this approval for Lynparza in the US, AstraZeneca will receive from MSD $100m in Collaboration Revenue, anticipated to be booked by the Company during the second quarter of 2020.
