Key inclusion & exclusion criteria

Inclusion criteria:
1. Be willing and able to provide written informed consent for the trial.
The subject may also provide consent for Future Biomedical Research.
However, the subject may participate in the main trial without
participating in Future Biomedical Research.
2. Be > or = 18 years of age on day of signing informed consent.
3. Have histologically confirmed epithelial ovarian cancer, fallopian tube
cancer or primary peritoneal cancer
4. Have received a front line platinum-based regimen (administered via
either IV or IP route) per local standard of care or treatment guideline
following the primary or interval debulking surgery with documented
disease recurrence.
Note: Maintenance treatment following the front line treatment is
permitted and counted together as part of the front line treatment.
5. Have fulfilled the following additional requirements regarding prior
treatments for ROC depending on the cohort subject is to be enrolled.
Each subject must have documented evidence of clinical response or
disease stabilization to the last regimen received.
Cohort A: Have received 0 to 2 additional prior lines for treating ROC (or
1 to 3 total prior lines counting the front line) and must have a PFI of >
or = 3 to 12 months if the last regimen received is a platinum-based, or
a TFI of > or = 3 to 12 months if the last regimen received is a nonplatinum-
based.
Cohort B: Have received 3 to 5 additional prior lines for treating ROC (or
4 to 6 total prior lines counting the front line) and must have a PFI of >
or =3 months if the last regimen received is a platinum-based, or a TFI
of > or = 3 months if the last regimen received is a non-platinum-based.
Note: PFI is defined as the time elapsed between the last dose of
platinum and the documented evidence of disease progression per
RECIST 1.1. Treatment-free interval is defined as the time elapsed
between the last dose of the regimen received and the documented
evidence of disease progression per RECIST 1.1.
6. Have measurable disease at baseline based on RECIST 1.1 as determined by the central imaging vendor.
Note: Tumor lesions situated in a previously irradiated area are
considered measurable if progression has been demonstrated in such
lesions.
7. Have an Eastern Cooperative Oncology Group (ECOG) performance
status of 0 or 1
8. Have a life expectancy of > or =16 weeks.
9. Have provided a tumor tissue sample either collected from prior
cytoreductive surgery or fresh newly obtained tumor tissue at screening.
Formalin-fixed paraffin-embedded block specimens are preferred to
slides. Additional samples may be requested if tumor tissue provided is
not adequate for quality and/or quantity as assessed by the central
laboratory.
Note 1: Tumor tissue samples from recent biopsy are much preferred as
it represents the current disease status and is much more informative
for understanding the correlation between clinical activity and tumor
microenvironment.
If available, paired tumor tissue samples from prior cytoreductive
surgery and recent biopsy are strongly encouraged in order to
understand the changes in tumor microenvironment during the course of
the treatments.
Note 2: For archival tumor tissue samples, block specimens are much
preferred than slides. If submitting unstained cut slides, freshly cut
slides should be submitted to the testing laboratory within 14 days from
when the slides are cut. See Section 4.2.3.3 in protocol for an
explanation.
10. Have demo
Exclusion criteria:
1. Is currently participating in or has participated in a clinical study and
received an investigational agent or used an investigational device
within 4 weeks prior to the first dose of study treatment.
Note: Subjects who have entered the follow-up phase of an
investigational study may participate as long as it has been 4 weeks
since the last dose of the previous investigational agent or device.
2. Has an active autoimmune disease that has required systemic
treatment in the past 2 years (i.e. use of disease modifying agents,
corticosteroids or immunosuppressive drugs). Replacement therapy
(e.g., thyroxine, insulin, or physiologic corticosteroid replacement
therapy for adrenal or pituitary insufficiency) is not considered a form of
systemic treatment.
3. Has a diagnosis of immunodeficiency or is receiving systemic steroid
therapy or any other form of immunosuppressive therapy within 7 days
prior to the planned first dose of the study. The use of physiologic doses
of corticosteroids may be approved after consultation with the Sponsor.
4. Has had prior anti-cancer mAb chemotherapy, targeted small molecule
therapy, or radiation therapy within 4 weeks prior to the planned first dose of the study
5. Has not recovered from AE to < or = Grade 1 or prior treatment level
due to a previously administered agent.
Note: Subjects with < or = Grade 2 neuropathy or alopecia of any grade
are an exception to this criterion and may qualify for the study.
Note: If subject received major surgery, they must have recovered
adequately from the toxicity and/or complications from the intervention
prior to starting therapy.
6. Has EOC with mucinous histology subtype.
7. Has a known additional malignancy that progressed or required active
treatment within the last 5 years. Exceptions include basal cell
carcinoma of the skin, squamous cell carcinoma of the skin that has
undergone potentially curative therapy or in situ cervical cancer.
8. Has known active central nervous system metastases and/or
carcinomatous meningitis. Subjects with previously treated brain
metastases may participate provided they have stable brain metastases.
9. Has known history of, or any evidence of active, non-infectious
pneumonitis.
10. Has an active infection requiring systemic therapy.
11. Has symptoms of bowel obstruction in the past 3 months
12. Has a history or current evidence of any condition, therapy, or
laboratory abnormality that might confound the results of the trial,
interfere with the subject's participation for the full duration of the trial,
or is not in the best interest of the subject to participate, in the opinion
of the treating investigator.
13. Has known psychiatric or substance abuse disorders that would
interfere with cooperation with the requirements of the trial.
14. Is pregnant or breastfeeding, or expecting to conceive children
within the projected duration of the trial, starting with the screening
visit through 120 days after the last dose of trial treatment.
15. Has received prior therapy with an anti-PD-1, anti-PD-L1, anti-PD-L2
agent or with an agent directed to another co-inhibitory T-cell receptor
(e.g. CTLA-4, OX-40, CD137) or has participated in prior pembrolizumab
trials.
16. Has a known history of human immunodeficiency virus (HIV) (HIV
1/2 antibodies).
