FDA Priority Review for Pfizer Breast Cancer Therapy

FDA has accepted for priority review a Pfizer NDA for talazoparib for use in patients with germline (inherited) BRCA-mutated (gBRCAm), HER2-negative locally advanced or metastatic breast cancer. The submission is based on results from the EMBRACA trial, which evaluated talazoparib versus chemotherapy in this patient population. The user fee review action goal date is expected in December.

 

The EMBRACA trial evaluated once-daily talazoparib compared to physician’s choice chemotherapy (capecitibine, eribulin, gemcitabine or vinorelbine) in 431 patients with an inherited BRCA1/2 mutation and locally advanced or metastatic triple negative or hormone receptor-positive (HR+)/HER2-negative breast cancer. The study met its primary endpoint, demonstrating superior progression-free survival with talazoparib versus chemotherapy, according to the company.
