      Trial Summary

      This is a Phase Ib, open-label, non-randomized study in patients with previously treated advanced ovarian or endometrial cancer (Part 1) and platinum-sensitive ovarian cancer or triple-negative breast cancer (TNBC) (Part 2) to investigate the dose, safety, pharmacokinetics, and preliminary efficacy of rucaparib in combination with atezolizumab. The study is conducted in 2 parts: a Dose-Finding Phase (Part 1) and a Dose-Expansion Phase (Part 2)

      • For Part 2 ONLY, have a deleterious germline or somatic breast cancer susceptibility gene 1 (BRCA1) or BRCA2 mutation or tumors that are wild-type BRCA but show high levels of loss of heterozygosity (LOH) (tBRCAwt/LOHhigh) signature
