What was measured

Time to treatment failure due to toxicity was defined as the time from the date of randomization to the date a participant discontinued study treatment due to TEAEs.

Analysis population: Safety analysis population included all randomized participants who received at least 1 dose of study treatment. Data is reported for pMMR participants. Here "overall number of participants analyzed" signifies participants who were evaluable for this outcome measure.

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.
