AstraZeneca and MSD announced that the FDA informed AstraZeneca that it will extend the Prescription Drug User Fee Act (PDUFA) date by three months to provide further time for a full review of the supplementary new drug application (sNDA) for Lynparza (olaparib) in combination with abiraterone and prednisone or prednisolone for the treatment of metastatic castration-resistant prostate cancer (mCRPC). The companies will continue to work with the FDA to facilitate the completion of the agency’s review.
The sNDA is based on results from the pivotal PROpel Phase III trial, which were published in June 2022 in NEJM Evidence. In August 2022, the sNDA was granted Priority Review and AstraZeneca and MSD are committed to working with the FDA to bring this treatment option to patients with mCRPC.
In November, the European Medicines Agency’s Committee for Medicinal Products for Human Use adopted a positive opinion recommending approval of Lynparza in combination with abiraterone and prednisone or prednisolone in the EU for the treatment of adult patients with mCRPC for whom chemotherapy is not clinically indicated. This combination is also undergoing regulatory reviews in other countries.
Lynparza is approved in the US based on results from the PROfound Phase III trial as monotherapy for patients with homologous recombination repair (HRR) gene-mutated mCRPC (BRCA-mutated and other HRR gene mutations) who have progressed following prior treatment with enzalutamide or abiraterone; and in the EU, Japan, and China for patients with BRCA-mutated mCRPC who have progressed following prior therapy that included a new hormonal agent.
