Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This trial is a multicenter, single-arm, phase II study evaluating the efficacy of pembrolizumab and bevacizumab in combination with platinum-based chemotherapy (PBC) followed by pembrolizumab, bevacizumab and olaparib as a maintenance therapy in patients with platinum-sensitive recurrent ovarian cancer.This study is planned to enroll eligible 35 patients from multiple study sites in Japan.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Participant is at least 20 years of age on the day of signing informed consent with histologically confirmed epithelial ovarian cancer (excluding borderline ovarian tumor) excluding mucinous carcinoma.
2. Participant has received only one regimen of PBC (3 cycles or more) as prior therapy with clinical CR (determined by negative clinical examination and a normal CA-125 level).
3. Participant has documentation of progressive disease at least 6 months from completion of PBC (platinum-sensitive).
4. Participant with measurable disease based on RECIST 1.1 at screening
5. Participant is able to provide a core or excisional biopsy of a tumor for testing of PD-L1 status, etc.
6. Participant with Eastern Cooperative Oncology Group (ECOG) PS of 0 to 1 at the screening
7. Participant has a life expectancy of at least 12 weeks as determined by the investigators.
8. Participant has adequate organ function.

Exclusion Criteria

1. A Women of Childbearing Potential (WOCBP) who has a positive urine pregnancy test at screening. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
2. Participant has received prior therapy with an 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 (eg, CTLA-4, OX-40, CD137).

4. Participant has received prior radiotherapy within 2 weeks of the first dose of study drug.
5. Participant has received major surgery within 4 weeks prior to the first dose of study drug.
6. Participant has received a live vaccine or live-attenuated vaccine within 30 days prior to the first dose of study drug. Administration of killed vaccines is allowed.
7. Participant is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to the first dose of study drug.
8. Participant has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of study drug.
9. Participant has a known additional malignancy that is progressing or has required active treatment within the past 3 years.
10. Participant has known active CNS metastases and/or carcinomatous meningitis.
11. Participant has severe hypersensitivity (≥Grade 3) to the study treatment and/or any of its excipients.
12. Participant has active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs).
13. Participant has a history of (non-infectious) pneumonitis/interstitial lung disease that required treatment with steroids or has current pneumonitis/interstitial lung disease.
14. Participant has an active infection requiring systemic therapy.
15. Participant has a known history of Human Immunodeficiency Virus (HIV) infection.
16. Participant 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.
17. Participant has received colony-stimulating factors (granulocyte colony stimulating factor \[G-CSF\], granulocyte macrophage colony-stimulating factor \[GM-CSF\] or recombinant erythropoietin) within 2 weeks prior to the first dose of study drug.
18. Participant has clinically serious cardiovascular/cerebrovascular diseases (eg, cerebrovascular accident/stroke \[less than 6 month prior to enrollment\], myocardial infarction \[less than 6 month prior to enrollment\], uncontrolled and potentially reversible cardiac conditions \[unstable ischemia, uncontrolled symptomatic arrhythmia, congestive heart failure, QTcF prolongation \>500 msec, electrolyte disturbances, hypertension defined as systolic \>150 mmHg or diastolic \>90 mmHg etc.\] or participant has congenital long QT syndrome).
