The purpose of this study is to compare the efficacy of pembrolizumab + lenvatinib to chemotherapy in female participants with Stage III, IV, or recurrent endometrial carcinoma. It is hypothesized that the combination of pembrolizumab + lenvatinib will be superior to chemotherapy for progression-free survival (PFS) per Response Evaluation Criteria In Solid Tumors version 1.1 (RECIST 1.1) by blinded independent central review (BICR). It is also hypothesized that the combination of pembrolizumab + lenvatinib will be superior to chemotherapy for overall survival (OS). As of Amendment 7 eligible participants on study completion will be able to transition to an extension study, if available, in which they can continue to receive pembrolizumab monotherapy, lenvatinib monotherapy, or a combination of both pembrolizumab and lenvatinib as received in the parent study.
Lenvatinib 4 mg or 10 mg capsules at a total daily dose of 20 mg taken by mouth once per day.
Pembrolizumab 200 mg intravenous (IV) infusion given on Day 1 of each cycle.
Paclitaxel 175 mg/m\^2 IV infusion given on Day 1 of each cycle.
Carboplatin 10 mg/mL IV infusion at a total dose of are-under-the-curve (AUC) 6 (per Calvert's formula) given on Day 1 of each cycle.
