Inclusion Criteria: * Female, at least 18 years of age at the time of informed consent. * Histological confirmed endometrial cancer of the endometrioid, serous, or undifferentiated type. Carcinosarcoma of the uterus is also allowed. * 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 chemothe…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
