You may be able to join if
- Sign and date the informed consent form prior to the start of any study-specific qualification procedures
- Eastern Cooperative Oncology Group performance status of 0 or 1
- Has adequate organ and bone marrow function as assessed by local laboratory within 14 days prior to initiation of study treatment as defined below. Organ and bone marrow function criteria must also be met when laboratory tests are repeated within 3 days of initiation of study treatment as appropriate. Transfusion (red blood cell or platelet) or granulocyte-colony stimulating factor (G-CSF) administration is not allowed within 2 weeks prior to screening laboratory tests.Adequate organ/bone marrow function is defined in inclusion criterion 11 of the protocol.
- If the participant is a female of childbearing potential, she must have a negative serum pregnancy test within 72 hours or urine test within 24 hours before the first dose of study drug and must be willing to use highly effective birth control upon enrollment, during the Treatment Period, and for at least the time required to eliminate each study treatment after the last dose. Male partners of subjects with childbearing potential should use additional barrier methods of contraception for the durationof same period. The length of time required to continue contraception for each study treatment is listed in inclusion criterion 12 of the protocol.
- Female participants must not donate, or retrieve for their own use, ova from the time of screening and throughout the study treatment period, and for at least the time required to eliminate each study treatment after the last dose, as described in the inclusion criterion 12 of the protocol.
- Is willing and able to comply with scheduled visits, drug administration plan, laboratory tests, other study procedures, and study restrictions
You likely can't join if
- Has clear cell, mucinous, or sarcomatous histology, mixed tumors containing any histology, or low-grade/borderline OVC. (Note for Phase 3 [Part B]: seromucinous, low-grade serous carcinoma or ovarian sarcoma, carcinosarcoma and undifferentiated carcinoma are excluded.)
- Has a history of receiving live-attenuated vaccine (messenger RNA [mRNA] and replication-deficient adenoviral vaccines are not considered attenuated live vaccines) within 30 days prior to the first exposure to study intervention
- For Phase 3 (Part B) only: Has clinical symptoms or radiographic evidence of intestinal obstruction for the control group
- Clinically active brain metastases, spinal cord compression, or leptomeningeal carcinomatosis, defined as untreated or symptomatic, or requiring therapy with steroids or anticonvulsants to control associated symptoms. Subjects with untreated and asymptomatic brain metastases or subjects with treated brain metastases who are no longer symptomatic and who require no treatment with steroids may be included in the study if they have recovered from the acute toxic effect of radiotherapy, at the investigator’s discretion. A minimum of 2 weeks must have elapsed between the end of radiotherapy and randomization and there should be no evidence of progression or need for steroid treatment or anticonvulsants for at least 2 weeks prior to randomization.
- Any of the following within the past 6 months prior to randomization: cerebrovascular accident, transient ischemic attack, or other arterial thromboembolic event (eg, intestinal ischemia).
- Uncontrolled or significant cardiovascular disease as defined in exclusion criterion 5 of the protocol.

- For Phase 3 (Part B) only: Participants must be eligible for one of the treatments included in the Investigator's choice of chemotherapy arm
- Age ≥18 years or the minimum legal adult age (whichever is greater) at the time the informed consent form is signed
- Participants with histologically or cytologically documented high-grade serous ovarian cancer (OVC), high-grade endometrioid OVC, primary peritoneal cancer, or fallopian tube cancer
- For Phase 2 (Part A): Subjects must have at least 1 lesion, not previously irradiated, amenable to biopsy, and must consent to provide a pretreatment biopsy and on-treatment biopsy tissue sample (on-treatment biopsy sample not required for the Phase 3 part of the study). Fresh pretreatment biopsy may be waived for subjects who consent to provide an archival tumor tissue sample from a lesion not previously irradiated, performed within 6 months of consent, and performed after treatment with their most recent cancer therapy regimen For Phase 3 (Part B): Subjects must be willing and able to provide most recently collected (within 5 years of signing the ICF) archival tumor samples with sufficient quantity and quality of tissue. Alternatively, if an archival tumor tissue sample is not available, a newly obtained tumor tissue biopsy from at least 1 lesion not previously irradiated and amenable to core needle biopsy must be provided. If a biopsy procedure is required, the subject must have a lesion that can be biopsied at an acceptable clinical risk as judged by the investigator to be eligible for this trial

- Has platinum-resistant disease. If a subject had only 1 line of platinum therapy, must have received at least 4 cycles of platinum, must have had a best response of not PD, and then progressed between >90 and ≤180 days after the date of the last dose of platinum If a subject had 2 or 4 lines of platinum therapy, must have received at least 2 cycles of platinum and have progressed on or within 180 days after the date of the last dose of platinum Note: Subjects who are primary platinum refractory during front-line treatment (defined as disease that has progressed on or within ≤90 days of the last dose of first line platinum therapy) are excluded.
