Olaparib and Tremelimumab in Treating BRCA1 or BRCA2 Mutation Carrier Patients with Recurrent Ovarian, Fallopian Tube, or Primary Peritoneal Cancer

Trial Status: closed to accrual and intervention

This phase I/II trial studies the side effects and best dose of tremelimumab when given together with olaparib in treating patients confirmed to carry a breast cancer 1 (BRCA1) or breast cancer 2 (BRCA2) germline mutation with ovarian, fallopian tube, or primary peritoneal cancer that has has come back (recurrent). Tremelimumab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Olaparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. Giving tremelimumab and olaparib may work better in treating BRCA mutation carrier patients with ovarian, fallopian tube, or primary peritoneal cancer.
