tablet

Active Ingredient

Selinexor

Dosage Form

116

Dosage

Endpoints

Investigator assessed PFS per RECIST v1.1

Inclution Criteria

1. At least 18 years of age (or older, if age of adulthood is older per local regulations) at the time of signing informed consent.
2.
Histologically confirmed EC including endometrioid, serous, undifferentiated, and carcinosarcoma.
3.
TP53 wt assessed by NGS, evaluated by a central vendor.
4. Completed at least 12 weeks of platinum-based therapy with or without ICI for Primary Stage IV or at first relapse and achieved confirmed partial or complete response (PR or CR) by imaging, according to RECIST version 1.1.
Treatment for Primary Stage IV disease is defined as:
a.
had first-line platinum-based therapy along with primary or later debulking surgery and achieving an R0 resection (R0 resection indicates a macroscopic complete resection of all visible tumor), and achieved CR after at least 12 weeks platinum-based therapy, and/or continue to have no evidence of disease after at least 12 weeks of chemotherapy and surgery OR
b.
had first-line platinum-based therapy along with primary or later debulking surgery and achieving R1 or R2 resection (incomplete removal of all macroscopic disease) and achieved PR or CR after at least 12 weeks platinum-based chemotherapy, OR
c.
had no surgery and achieved PR or CR after at least 12 weeks platinum-based chemotherapy.

Exclusion Criteria

1.
Has any uterine sarcomas (carcinosarcomas – not excluded), clear cell or small cell carcinoma with neuroendocrine differentiation.
2. Has received a blood or platelet transfusion during the 2 weeks prior to C1D1. Patients’ hemoglobin must be assessed within 2 weeks of screening and at least 1 week post transfusion.
3. Has insufficient time since or not fully recovered from procedures or anti-cancer therapy, defined as:

Persisting adverse events from a previous surgery or procedure that has not resolved ≤28 days prior to Day 1 dosing.
4. Has ongoing clinically significant anti-cancer therapy-related toxicities CTCAE Grade >1, with the exception of alopecia. In specific cases, patients whose toxicity has stabilized or with Grade 2 non-hematologic toxicities can be allowed following documented approval by the Sponsor’s Medical Monitor
5. Had palliative radiotherapy within 14 days of the intended C1D1. Palliative radiotherapy may be permitted for symptomatic control of pain from bone metastases, provided that the radiotherapy does not involve target lesions, and the reason for the radiotherapy does not reflect evidence of disease progression.
6. Has any gastrointestinal dysfunctions that could interfere with the absorption of selinexor (eg, bowel obstruction, inability to swallow tablets, malabsorption syndrome, unresolved nausea, vomiting, diarrhea CTCAE v 5.0 > Grade 1).
7. Unable to tolerate two forms of antiemetics prior to each dose for at least 2 cycles will not be eligible for the trial.
8. Has an active, ongoing or uncontrolled infection requiring parenteral antibiotics, antivirals, or antifungals within 1 week of screening.
9. Has a serious psychiatric or medical condition that could interfere with participation in the study or in the opinion of the Investigator would make study involvement unreasonably hazardous.
10. Had previous treatment with an XPO1 inhibitor.
11. Has stable disease or PD on the post-chemotherapy scan or clinical evidence of progression prior to randomization.
12. Has received any systemic anti-cancer therapy including investigational agents ≤3 weeks (or ≤5 half-lives of the drug [whichever is shorter]) prior to C1D1.
13. Has major injuries or any surgery within 14 days prior to C1D1 and/or planned major surgery during the on-treatment study period.
