The purpose of this Phase 2 study is to compare two doses of ONC-392 in combination with a fixed dose of pembrolizumab in participants with ovarian cancer who are resistant to platinum-based chemotherapy and have disease progression on line of therapy containing bevacizumab. Results from this study will be used to inform the study design, patient population, and dose selection for future studies in advanced ovarian cancer.
This is a study to test the safety and efficacy with the combination of a next generation anti-CTLA-4 antibody, ONC-392, and anti-PD-1 antibody, pembrolizumab, in platinum resistant ovarian cancer patients.
