- Progression Free Survival (PFS) [ Time Frame: 30 months after FPI ]Compare progression free survival (PFS) of the two treatment arms as assessed by the investigator, per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1.
- PFS, as assessed by a Blinded Independent Central Review (BICR), per RECIST v1.1 [ Time Frame: 30 months after FPI ]Time from randomization until documented Progression of Disease (PD) or death due to any cause, whichever occurs first. Documented PD will be based on BICR assessments.
- Disease specific survival (DSS) [ Time Frame: 30 months after FPI ]Time from randomization until date of death from endometrial cancer.
- Overall survival (OS) [ Time Frame: 30 months after FPI ]Time from randomization until date of death from any cause.
- Time to first subsequent treatment (TFST) [ Time Frame: 30 months after FPI ]Time from randomization until date of initiation of first therapy after discontinuation of study drug or death, whichever occurs first.
- Progression-free survival after consecutive treatment (PFS2) [ Time Frame: 30 months after FPI ]Time from randomization until the second documented disease progression or death due to any cause by any cause on any subsequent line of anticancer therapy.
- Time to Second Subsequent Treatment (TSST) [ Time Frame: 30 months after FPI ]Time from randomization until date of initiation of second therapy after discontinuation of study drug or death, whichever occurs first.
- Disease Control Rate (DCR) [ Time Frame: 30 months after FPI ]Best response of Complete Response (CR), Partial Response (PR), or Stable Disease (SD) among patients with PR as best response to prior chemotherapy.
- Health-Related Quality of Life (HR-QoL) as measured by EORTC QLQ30 [ Time Frame: 30 months after FPI ]Patient-reported outcomes will be measured by the EORTC QLQ30 questionnaire.
- Health-Related Quality of Life (HR-QoL) as measured by EORTC QLQ-EN24 [ Time Frame: 30 months after FPI ]Patient-reported outcomes will be measured by the EORTC QLQ-EN24 questionnaire.
