Priority review to olaparib for treating mCRPC

March 6, 2020 0 By FM

AstraZeneca and MSD announced that a supplemental New Drug Application for olaparib has been accepted and granted Priority Review in the US for patients with metastatic castration-resistant prostate cancer (mCRPC) and deleterious or suspected deleterious germline or somatic homologous recombination repair (HRR) gene mutations.

Results of the PROfound trial showed olaparib significantly reduced the risk of disease progression or death by 66% based on a hazard ratio of 0.34 (p<0.0001) vs. abiraterone or enzalutamide in patients with BRCA1/2 or ATM-mutated mCRPC, the primary endpoint of the trial.

The trial also showed that olaparib reduced the risk of disease progression or death by 51% based on a hazard ratio of 0.49 (p<0.0001) vs. abiraterone or enzalutamide in the overall trial population of patients with HRR-mutated (HRRm) mCRPC (those with mutations in the genes for BRCA1/2, ATM, CDK12 or 11 other HRRm genes; key secondary endpoint). 

Olaparib is currently approved in 65 countries, including those in the EU, for the maintenance treatment of platinum-sensitive relapsed ovarian cancer, regardless of BRCA status.
