A Study of Oral Rucaparib in Patients With a Solid Tumor (Phase I) or With gBRCA Mutation Ovarian Cancer (Phase II)

Rucaparib (CO-338; formerly known as PF 01367338 and AG 14699) is an orally available, small molecule inhibitor of poly-adenosine diphosphate \[ADP\] ribose polymerase (PARP) being developed for treatment of ovarian cancer associated with homologous recombination \[HR\] DNA repair deficiency (HRD). The safety and efficacy of rucaparib has been evaluated in several Phase 1 and Phase 2 studies. An oral formulation is the focus of current development efforts. Rucaparib is currently being investigated as monotherapy in patients with cancer associated with BRCA1 or BRCA2 mutations. For this study, it is anticipated that rucaparib will promote cell death in the BRCA-deficient tumor cells of ovarian cancer patients with evidence of a germline mutation, thereby limiting tumor progression and providing therapeutic benefit.
