- Participants must have a histologically confirmed diagnosis of epithelial high-grade ovarian, fallopian tube or primary peritoneal carcinoma (serous, endometrioid, or clear cell).
- Participants are newly diagnosed International Federation of Gynecology and Obstetrics (FIGO) stage III or IV and have received primary debulking surgery or interval debulking surgery.
- Participants must have adequate organ function.
- Women of childbearing potential must be willing to use a highly effective method of birth control and agree not to donate eggs (ova, oocytes) or freeze/store eggs for the duration of the study and for ≥ 7 months after the last dose of study treatment.
You may not qualify if:
- Participants have ovarian, fallopian tube, or peritoneal cancer of nonepithelial origin.
- Participants have either a germline or somatic BReast CAncer gene (BRCA) mutation as per local test.

BeOne shares data on completed studies responsibly and provides qualified scientific and medical researchers access to data and supporting documentation for clinical trials in dossiers for medicines and indications after submission and approval in the United States, China, and Europe. Clinical trials supporting subsequent local approvals, new indications, or combination products are eligible for sharing once corresponding regulatory approvals are achieved. BeOne shares data only when permitted by applicable data privacy and security laws and regulations, when it is feasible to do so without compromising the privacy of study participants, and other considerations. Qualified researchers with appropriate competencies who are engaged in novel scientific research may submit a request for participant-level data with a research proposal for BeOne review. Research teams must include a biostatistician and sign a Data Sharing Agreement prior to receiving access to clinical trial data.
