Study Summary

This trial is testing a new treatment for endometrial cancer that could help the body's immune system fight the cancer.

Who is the study for?
This trial is for adults with inoperable endometrial cancer who can undergo radiation therapy. They must have adequate organ function, not be pregnant or breastfeeding, and agree to use contraception if of childbearing potential. Excluded are those with prior endometrial cancer treatments, metastatic disease outside the uterus, certain recent malignancies, previous anti-PD-1/PD-L1 drugs usage, known brain metastases, uncontrolled medical conditions or infections.Check my eligibility
What is being tested?
The trial tests TSR-042 (an immunotherapy drug) alongside standard radiation treatment for patients with inoperable endometrial cancer. It aims to assess whether adding TSR-042 can boost the immune system's response against tumor cells and improve outcomes compared to radiation alone.See study design
What are the potential side effects?
TSR-042 may cause side effects similar to other immunotherapies which include but are not limited to fatigue, skin reactions at injection sites, flu-like symptoms such as fever and chills, nausea or diarrhea. More serious side effects might involve the immune system attacking normal organs/tissues.

Experimental Treatment
Group I: TSR-042 and BrachytherapyExperimental Treatment4 Interventions
Patients will receive four doses of TSR-042. The first dose is given 21 days prior to the first planned brachytherapy fraction. The second dose is given 21 (+3) days later, corresponding to the time of brachytherapy fraction #1. The third dose is given 21 (+3) days after dose 2, corresponding to the time of brachytherapy fraction #4. The fourth dose is given 21 (+3) days after dose corresponding to 1 weeks after brachytherapy fraction #6. Brachytherapy will consist of 6 weekly fractions of 6 Gy per fraction (total 36Gy)
