Dr. Dorff on the Investigation of PARP Inhibitors in mCRPC - OncLive
Tanya Dorff, MD, medical oncologist, associate clinical professor, Department of Medical Oncology & Therapeutics Research, City of Hope, discusses the investigation of PARP inhibitors in metastatic castration-resistant prostate cancer (mCRPC). New data have presented clinicians with the idea of utilizing PARP inhibitors in combination with androgen receptor (AR) inhibitors in patients with mCRPC, irrespective of homologous recombination repair (HRR) mutation status, Dorff says. Updated data from the phase 3 PROpel trial (NCT03732820) presented at the 2022 ESMO Congress showed that patients treated with olaparib (Lynparza) plus abiraterone acetate (Zytiga) and prednisone or prednisolone experienced a median radiologic progression-free survival (rPFS) of 25.0 months, compared with 16.4 months for those given abiraterone acetate and prednisone or prednisolone alone. Although the phase 3 MAGNITUDE trial (NCT03748641) of niraparib (Zejula) plus abiraterone acetate vs abiraterone ace...
