Summary

This trial is testing if selinexor can help treat endometrial cancer that has progressed or come back after initial treatment.

Who is the study for?
This trial is for women aged 18+ with advanced or recurrent endometrial cancer who've responded to taxane-platinum chemotherapy. They must have good performance status, adequate organ function, and not be pregnant or breastfeeding. Exclusions include previous treatment with certain inhibitors or immunotherapies, recent transfusions, major surgeries, other active cancers (except some skin cancers), uncontrolled infections, and inability to swallow tablets.
What is being tested?
The SIENDO trial tests if selinexor works as a maintenance therapy after initial successful chemotherapy in patients with endometrial cancer. Participants are randomly assigned in a 2:1 ratio to receive either selinexor (80 mg weekly) or a placebo until their disease progresses.
What are the potential side effects?
Selinexor may cause side effects like nausea, vomiting, fatigue, loss of appetite, weight loss, diarrhea or constipation. It can also affect blood counts leading to anemia and increase the risk of infections due to low white blood cell counts.
