AstraZeneca's (AZN) Lynparza Gets FDA Nod In 1st Line Setting

 | Dec 20, 2018 05:34AM ET

AstraZeneca Plc. (NYSE:AZN) and partner Merck & Co., Inc. (NYSE:MRK) announced that the FDA has approved a label expansion of its advanced ovarian cancer drug Lynparza. The FDA has approved Lynparza as a first-line maintenance therapy for BRCA-mutated advanced ovarian cancer. It is the first regulatory approval for a PARP inhibitor in first-line maintenance setting.

We note that Lynparza is already marketed in the United States for platinum-sensitive relapsed ovarian cancer, regardless of BRCA status and germline BRCAm HER2-negative metastatic breast cancer.

The approval in the first-line setting was based on data from the pivotal phase III SOLO-1 study, which demonstrated that Lynparza (olaparib) tablets led to a statistically-significant and clinically-meaningful improvement in progression free survival (PFS) compared to placebo in women with BRCA-mutated (BRCAm) advanced ovarian cancer who were in complete or partial response following first-line standard platinum-based chemotherapy.

In the Lynparza arm, 60% of the patients were progression free at 36 months compared with 27% in the placebo arm. Lynparza reduced the risk of disease progression or death by 70% compared to placebo, following response to platinum-based chemotherapy.

With the approval for expanded use in the first-line setting, sales of Lynparza can improve in the future quarters.

Other PARP inhibitors available in the market are Tesaro, Inc.’s (NASDAQ:TSRO) Zejula and Clovis Oncology, Inc.’s (NASDAQ:CLVS) Rubraca. Zejula and Rubraca are also being evaluated in late-stage studies in the first-line maintenance setting for the treatment of ovarian cancer patients who have responded to platinum-based chemotherapy.

This year so far, AstraZeneca’s shares have risen 13.7% compared with the industry ’s growth of 4.9%.
