Who can take part
You may be able to join if
- Has a histologically confirmed diagnosis of inoperable, Stage III or IV or recurrent Endometrial Carcinoma (EC) or carcinosarcoma (mixed Mullerian tumor) that is centrally confirmed as dMMR.
- Has radiographically evaluable disease, either measurable or non-measurable per RECIST 1.1, as assessed by the investigator. Note: primary Stage IVB that has undergone surgical resection is allowed regardless of presence of measurable or evaluable disease.
- Has received no prior systemic therapy for EC except for the following: a. May have received 1 prior line of systemic platinum-based adjuvant and/or neoadjuvant chemotherapy in the setting of curative-intent resection if the recurrence occurred ≥6 months after the last dose of chemotherapy. b. May have received prior radiation with or without radiosensitizing chemotherapy if >2 weeks before the start of study intervention. Participants must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis. A 1-week washout is permitted for palliative radiation (≤2 weeks of radiotherapy) to non-central nervous system (CNS) disease. c. c. May have received prior hormonal therapy for treatment of EC, provided that it was discontinued ≥1 week prior to randomization.
- Has Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 within 7 days before randomization.
- Is not pregnant or breastfeeding and agrees to not donate eggs and use a highly effective contraceptive method for 120 days after the last dose of pembrolizumab or 180 days after the last dose of chemotherapy if a woman of childbearing potential (WOCBP)
- Has a negative highly sensitive pregnancy test (urine or serum) within 24 hours for urine or 72 hours for serum before the first dose of study intervention if a WOCBP
You likely can't join if
- Has uterine mesenchymal tumor such as an endometrial stromal sarcoma, leiomyosarcoma, or other types of pure sarcomas. Adenosarcomas and neuroendocrine tumors are not allowed.
- Has a known additional malignancy that is progressing or has required active treatment within the past 3 years with the exception of basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or carcinoma in situ (excluding carcinoma in situ of the bladder) that have undergone potentially curative therapy are not excluded
- Has known active CNS metastases and/or carcinomatous meningitis
- Has a known intolerance to any study intervention and/or any of its excipients
- Has an active autoimmune disease that has required systemic treatment in past 2 years
- Has a history of (noninfectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease
