Study Summary

The purpose of this study is to assess the efficacy and safety of treatment with carboplatin/paclitaxel\* PLUS pembrolizumab (MK-3475) and maintenance olaparib (MK-7339) in women with epithelial ovarian cancer (EOC), fallopian tube cancer, or primary peritoneal cancer. The primary study hypotheses are that the combination of pembrolizumab plus carboplatin/paclitaxel\* followed by continued pembrolizumab and maintenance olaparib is superior to carboplatin/paclitaxel alone with respect to Progression Free Survival (PFS) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) in participants with programmed death-ligand 1 (PD-L1) positive tumors (Combined Positive Score \[CPS\]≥10) and in all participants, and that the combination of pembrolizumab plus carboplatin/paclitaxel followed by continued pembrolizumab is superior to carboplatin/paclitaxel alone with respect to PFS per RECIST 1.1 in participants with PD-L1 positive tumors (CPS≥10) and in all participants.

Primary Outcome

PFS is defined as the time from randomization to the first documented progressive disease (PD) per RECIST 1.1 based on Investigator assessment or death due to any cause, whichever occurs first. Per RECIST 1.1, PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. Note: The appearance of one or more new lesions and the unequivocal progression of non-target lesions is also
