Brief Summary:
This is a prospective, multicenter, double-blind, placebo-controlled, randomized Phase 3 study. The purpose of the study is to obtain evidence of efficacy for maintenance selinexor in participants with advanced or recurrent endometrial cancer. Participants with primary stage IV or recurrent disease who are in partial or complete response after having completed a single line of at least 12 weeks of taxane-platinum combo therapy will be randomized in a 2:1 manner to maintenance therapy with 80 milligram (mg) with selinexor once weekly (QW) or placebo until progression.

- Completed a single line of at least 12 weeks of taxane-platinum combination therapy (not including adjuvant or neoadjuvant therapy), and achieved partial remission (PR) or complete remission (CR) according to RECIST version 1.1 for:
- Primary Stage IV disease, defined as:
- had a primary or later debulking surgery during first-line taxane-platinum therapy with R0 resection (R0 resection indicates a macroscopic complete resection of all visible tumor) and achieved CR after at least 12 weeks taxane-platinum chemotherapy, OR
- had a primary or later debulking surgery during first-line taxane-platinum therapy with R1 resection (R1 resection indicates incomplete removal of all macroscopic disease,) and achieved PR or CR after at least 12 weeks taxane-platinum chemotherapy, OR
- had no surgery and achieved PR or CR after at least 12 weeks taxane-platinum chemotherapy.
OR
- At first relapse (i.e., relapse after primary therapy including surgery and/or chemotherapy therapy for Stage I-IV disease), defined as:
- had Stage I-III disease at diagnosis and received at initial diagnosis adjuvant chemotherapy and relapsed later. Participants should have PR or CR after at least 12 weeks of taxane-platinum chemotherapy compared with the start of this chemotherapy at the time of relapse, OR
- had Stage I-III disease at diagnosis and did not receive adjuvant chemotherapy at initial diagnosis and relapsed later. Participants should have PR or CR after at least 12 weeks of taxane-platinum chemotherapy compared with the start of this chemotherapy at the time of relapse, OR
