This study looked at the benefit of using the PARP inhibitor niraparib to treat metastatic castration-resistant prostate cancer (mCRPC). Participants included those with an inherited or tumor mutation in BRCA1 or BRCA2 or an inherited or tumor mutation in another gene that affects DNA repair. Participants with an inherited or tumor mutation in BRCA1 or BRCA2 had better survival compared to those without a BRCA mutation. Side effects from niraparib were common, and consistent with previous reports for PARP inhibitors. (posted 9/6/2022)

Open Clinical Trials
The following studies are looking at PARP inhibitors and similar agents for treating people with advanced prostate cancer.
- NCT05932862: Study of a New InvestigationaI Inhibitor to Treat People with Advanced Solid Tumors. The study will test if an investigational treatment, XL309, is safe and works when used alone or in combination with a PARP inhibitor to treat people with some advanced solid tumors, including breast cancer.
- NCT05005728: XmAb®20717 Alone or in Combination With Chemotherapy or Targeted Therapy in Patients With Metastatic Castration-Resistant Prostate Cancer. This study will look at the safety and clinical activity of the drug XmAb20717 alone or in combination with standard-of-care anticancer therapies in patients with metastatic castration-resistant prostate cancer who have been treated with at least 2 prior lines of treatment.
- NCT03317392: Studying the Medication Olaparib Given with Radium-223 for Advanced Prostate Cancer with Bone Metastasis. This study is measuring the best dosage for and side effects of the drug combination olaparib and radium-223 to treat men with mCRPC that has spread to the bones.
- NCT05417594: Study of the PARP inhibitor AZD9574 Alone and Combined with Other Cancer Medicines to Treat People with Advanced Solid Cancers (CERTIS1 Study). This study is looking at a new PARP inhibitor called AZD9574 on its own and in combination with other anti-cancer drugs in people with advanced cancer that has come back or progressed.
