Oncology News Central (ONC)ODAC Backs Limiting Olaparib Combo in mCRPC

During its April 28 meeting, the FDA’s Oncologic Drugs Advisory Committee (ODAC) voted 11-1 on whether access to the combination should be limited to patients whose tumors carry BRCA mutations. The majority of members shared the FDA reviewers’ concerns regarding clinical trial results and uncertainty about whether people without the BRCA mutation would benefit from the regimen. The FDA argued that the results of the phase 3 PROpel clinical trial could not be applied to patients who had not had their BRCA or HRR mutation status determined. As a result, the FDA contended that the PROpel intention-to-treat (ITT) group was heterogeneous, complicating the interpretation and application of the trial’s results to unselected patients.
