Official title
A Phase 1-2 Study of the Combination of Olaparib and Tremelimumab, in BRCA1 and BRCA2 Mutation Carriers With Recurrent Ovarian Cancer
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Of the approximately 21,000 cases of ovarian cancer diagnosed annually in the U.S, ten percent are attributed to hereditary syndromes, most commonly the result of mutations in the breast cancer susceptibility genes 1 or 2 (BRCA1 or BRCA2). Mutation in these genes results in the inability to repair double-stranded breaks in DNA. Treating these tumors with poly(adenosine diphosphate \[ADP\]-ribose) polymerase (PARP) inhibitors results in the specific killing of BRCA negative cells by blocking a second DNA-repair mechanism. Treatment of ovarian cancer patients with PARP inhibitors has resulted in improved progression free survival (PFS), but not overall survival (OS). It's not completely understood why this is the case, but some preclinical studies using ovarian cancer models in mice have suggested that combining PARP inhibitors with immune system modulators like T cell checkpoint inhibitors improves long-term survival. Therefore, the purpose of this study is to evaluate the safety and efficacy of a combination of a PARP inhibitor (Olaparib) with a T cell checkpoint inhibitor (the anti-CTLA-4 antibody Tremelimumab) in women with recurrent BRCA mutation-associated ovarian cancer.
