Official title
A Phase 1/2 Study of Combination Olaparib and Radium-223 in Men With Metastatic Castration-Resistant Prostate Cancer With Bone Metastases (COMRADE)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This phase I/II trial studies the best dose and side effects of olaparib and how well it works with radium Ra 223 dichloride in treating patients with castration-resistant prostate cancer that has spread to the bone and other places in the body (metastatic). PARPs are proteins that help repair DNA mutations. PARP inhibitors, such as olaparib, can keep PARP from working, so tumor cells can't repair themselves, and they may stop growing. Radioactive drugs, such as radium Ra 223 dichloride, may carry radiation directly to tumor cells and not harm normal cells. Giving olaparib and radium Ra 223 dichloride may help treat patients with castration-resistant prostate cancer.
