What was measured

TEAEs were AEs that occurred (or worsened, if present at baseline) after the first dose of study drug through 28 days after the last dose. An AE was any untoward medical occurrence in a participant temporally associated with use of study treatment, whether or not related to the treatment. An SAE was any untoward medical occurrence at any dose that resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity or substantial disruption of the ability to conduct normal life functions, or was a congenital anomaly/birth defect. An irAE was any unfavorable and unintended immune-related sign, symptom, or disease (new or worsening) temporally associated with study therapy, regardless of whether a causal relationship with the therapy could be determined.

Analysis population: The analysis population included all randomized participants who received at least 1 dose of study treatment.

Groups in this outcome

Lenvatinib 20 mg + Pembrolizumab 200 mg

Participants with Endometrial cancer (EC) received lenvatinib 20 milligrams (mg) orally, once daily, plus pembrolizumab 200 mg intravenously, every 3 weeks in each 21-day cycle. Participants continued to receive treatment until disease progression, development of unacceptable toxicity, withdrawal of consent, completion of 35 treatments (approximately 2 years) with pembrolizumab, or sponsor termination of the study

Treatment of Physician's Choice(TPC):Doxorubicin or Paclitaxel

Participants with EC received either doxorubicin 60 milligrams per square meter (mg/m\^2) intravenously, every 3 weeks, in each 21-day treatment cycle, or paclitaxel 80 mg/m\^2 intravenously, weekly (3 weeks on/1 week off), in each 28-day treatment cycle. Participants continued to receive treatment until a lifetime cumulative dose of 500 mg/m\^2 doxorubicin, a maximum dose of paclitaxel per standard of care, or until disease progression, development of unacceptable toxicity, withdrawal of consent, or sponsor termination of the study.
