Study Summary

This trial is testing whether adding immunotherapy to radiation treatment can reduce the risk of cancer recurrence better than radiation alone for endometrial cancer patients.

Who is the study for?
This trial is for patients with newly diagnosed stage I-II endometrioid endometrial cancer. They must have had specific imaging, surgery, and show no signs of disease outside the uterus. Eligible participants should not have received prior therapy for their cancer, meet certain health criteria, and be within a set time after initial surgery.Check my eligibility
What is being tested?
The study is testing if adding pembrolizumab (an immunotherapy drug) to usual radiation therapy reduces the risk of cancer recurrence better than radiation alone in early-stage high intermediate risk endometrial cancer.See study design
What are the potential side effects?
Pembrolizumab may cause immune-related side effects such as inflammation in organs, infusion reactions, fatigue, skin rash or itching. Radiation can lead to localized skin irritation and fatigue.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Arm II (EBRT, brachytherapy, pembrolizumab)Experimental Treatment9 Interventions
Patients undergo EBRT and brachytherapy as in Arm I. Within 7 days prior to the start of radiation therapy, patients also receive pembrolizumab IV over 30 minutes on day 1. Treatment with pembrolizumab repeats every 6 weeks for up to 1 year (9 cycles) in the absence of disease progression or unacceptable toxicity. Patients also undergo collection of blood samples and CT scans, MRI scans, or x-ray imaging throughout the trial.
Group II: Arm I (EBRT, brachytherapy)Active Control8 Interventions
Patients undergo pelvic EBRT daily for 5-6 weeks and vaginal brachytherapy completed within 7 days after completion of EBRT in the absence of disease progression or unacceptable toxicity. Patients also undergo collection of blood samples and CT scans, MRI scans, or x-ray imaging throughout the trial.
