Has histologically confirmed International Federation of Gynecology and Obstetrics (FIGO) Stage III or Stage IV EOC (high-grade predominantly serous, endometrioid (any grade), carcinosarcoma, mixed mullerian with high-grade serous component, clear cell, or low-grade serous OC), primary peritoneal cancer, or fallopian tube cancer, Has just completed primary debulking surgery or is eligible for primary debulking surgery or is a potential candidate for interval debulking surgery, Is a candidate for carboplatin and paclitaxel chemotherapy, to be administered in the adjuvant or neoadjuvant setting, Candidates for neoadjuvant chemotherapy, has a cancer antigen 125 (CA-125) (kilounits/L):carcinoembryonic antigen (CEA; ng/mL) ratio greater than or equal to 25, Is able to provide a newly obtained core or excisional biopsy of a tumor lesion for prospective testing of BRCA1/2 and Programmed Cell Death-Ligand 1 (PD-L1) tumor markers status prior to randomization, Has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1, as assessed within 7 days prior to initiating chemotherapy in the lead-in period and within 3 days prior to Day 1 of Cycle 1, Female participants are not pregnant, not breastfeeding, and at least 1 of the following conditions applies: a.) Not a woman of childbearing potential (WOCBP) OR b.) Is a WOCBP and using a contraceptive method that is highly effective, with low user dependency, or be abstinent from heterosexual intercourse as their preferred and usual lifestyle, during the Treatment Period and for at least 120 days following the last dose of pembrolizumab (or pembrolizumab placebo) and bevacizumab (if administered), at least 180 days following the last dose of olaparib (or olaparib placebo), and at least 210 days following the last dose of chemotherapy and agrees not to donate eggs (ova, oocytes) to others or freeze/store for her own use for the purpose of reproduction during this period. The investigator should evaluate the potential for contraceptive method failure in relationship to the first dose of study treatment. A WOCBP must have a negative highly sensitive pregnancy test within either 24 hours (urine) or 72 hours (serum) before the first dose of study treatment. If a urine test cannot be confirmed as negative, a serum pregnancy test is required. The investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy. Contraceptive use by women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies, Has adequate organ function
Has mucinous, germ cell, or borderline tumor of the ovary, Has a known history of active tuberculosis (TB; Bacillus Tuberculosis), Has an active infection requiring systemic therapy, Has received colony-stimulating factors (eg, granulocyte colony stimulating factor [G-CSF], granulocyte macrophage colony-stimulating factor [GM-CSF] or recombinant erythropoietin) within 4 weeks prior to receiving chemotherapy during the lead-in period, Is considered to be of poor medical risk due to a serious, uncontrolled medical disorder, non-malignant systemic disease or active, uncontrolled infection, Has had surgery to treat borderline tumors, early-stage EOC, or early-stage fallopian tube cancer <6 months prior to screening, Has a known history of human immunodeficiency virus (HIV) infection, Has a known history of hepatitis B (defined as hepatitis B surface antigen [HBsAg] reactive) or known active hepatitis C virus (defined as HCV RNA [qualitative] is detected) infection. Testing for hepatitis B or hepatitis C is required at screening only if mandated by local health authority. Note: Participants with a history of hepatitis B but who are HBsAg negative are eligible for the study, Is either unable to swallow orally administered medication or has a gastrointestinal (GI) disorder affecting absorption (e.g. gastrectomy, partial bowel obstruction, malabsorption), Has uncontrolled hypertension, Has current, clinically relevant bowel obstruction (including sub-occlusive disease), abdominal fistula or GI perforation, related to underlying EOC (for participants receiving bevacizumab), Has a known or suspected deleterious mutation (germline or somatic) in either BRCA1 or BRCA2, Has a history of hemorrhage, hemoptysis or active GI bleeding within 6 months prior to randomization (for participants receiving bevacizumab), Is a WOCBP who has a positive urine pregnancy test within 72 hours before the first dose of chemotherapy in the lead-in period and within 72 hours prior to Day 1 of Cycle 1, is pregnant or breastfeeding, or is expecting to conceive children within the projected duration of the study, starting with screening through 120 days following the last dose of pembrolizumab (or pembrolizumab placebo) and bevacizumab (if administered), at least 180 days following the last dose of olaparib (or olaparib placebo), and at least 210 days following the last dose of chemotherapy, Has received prior treatment for any stage of OC, including radiation or systemic anti-cancer therapy (e.g. chemotherapy, hormonal therapy, immunotherapy, investigational therapy), Has received prior therapy with an anti-Programmed Cell Death-1 (anti-PD-1), anti-PD-L1, or anti-PD-L2 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (e.g. cytotoxic T lymphocyte antigen-4 [CTLA-4], OX 40, CD137), Has received prior therapy with either olaparib or any other poly(adenosine-ribose) polymerase (PARP) inhibitor, Has intraperitoneal chemotherapy planned or has been administered as first-line therapy, Has received a live vaccine within 30 days prior to the first dose of study treatment on Day 1 of Cycle 1, Has severe hypersensitivity (=Grade 3) to pembrolizumab, olaparib, carboplatin, paclitaxel, or bevacizumab (if using) and/or any of their excipients, Is currently receiving either strong (e.g. itraconazole, telithromycin, clarithromycin, protease inhibitors boosted with ritonavir or cobicistat, indinavir, saquinavir, nelfinavir, boceprevir, telaprevir) or
