Share

FDA has approved AstraZeneca’s Lynparza (olaparib) for the adjuvant treatment of adult patients with deleterious or suspected deleterious germline BRCA-mutated human epidermal growth factor receptor 2 (HER2)-negative high-risk early breast cancer who have been treated with neoadjuvant or adjuvant chemotherapy. Approval was based on data from the OlympiA study involving 1,836 patients who were evaluated for invasive disease-free survival (IDFS), which was defined as the time from randomization to date of first recurrence defined as invasive loco-regional, distant recurrence, contralateral invasive breast cancer, new cancer, or death from any cause.

 

“For IDFS, there were 106 events (12%) in the olaparib arm and 178 events (20%) in the placebo arm,” according to an FDA release. There were 75 deaths (8%) in the olaparib arm and 109 deaths (12%) in the placebo arm, it says. “A statistically significant improvement in IDFS and OS was demonstrated in patients in the Lynparza arm compared with the placebo arm.”
