Awards & highlights


This trial tests combining drugs and radiation to stop cancer from spreading.

Who is the study for?
This trial is for women aged 18 or older with recurrent or unresectable endometrial carcinoma that's not mismatch repair deficient. They must have a specific performance status, normal organ and marrow function, no recent investigational drug use, and agree to contraception if of childbearing potential. Exclusions include certain prior treatments, uncontrolled conditions like hypertension or infections (HIV/HBV/HCV), active CNS metastases, other progressing cancers, major surgery recovery, and immunosuppressive therapy within 21 days before the study.Check my eligibility
What is being tested?
The trial tests combining pembrolizumab (an immune checkpoint inhibitor) with lenvatinib (a targeted therapy) alongside a shortened course of pelvic radiation therapy in patients with endometrial cancer. The goal is to determine if this combination can prevent cancer cells from multiplying and spreading.See study design
What are the potential side effects?
Potential side effects may include high blood pressure due to lenvatinib; fatigue, skin reactions, or autoimmune-like symptoms from pembrolizumab; and typical radiation-associated discomfort such as localized skin irritation.

Trial Design

1Treatment groups
Experimental Treatment
Group I: Lenvatinib, Pembrolizumab and Hypofractionated (Hypofx) External Beam Radiation Therapy (EBRT) GroupExperimental Treatment3 Interventions
Participants in this group will receive a combination treatment of Lenvatinib, Pembrolizumab, and Hypofx Pelvic EBRT over a period of approximately 10 to 12 weeks. Lenvatinib - administered in a 3 plus 3 escalation/de-escalation design. Participants will receive 1 of 4 of the following dose levels: Dose level 1- 4 mg Dose level 2- 8 mg Dose level 3 (Starting dose) - 12 mg Dose level 4- 16 mg Pembrolizumab- 200 mg IV will be administered on Day 1, 22 and 43 HypoFx whole pelvic EBRT begins on Day 22 and continues for a total of 16 fractions of radiation given at a dose of 2.5 Gy per fraction for a total dose of 40.0 Gy delivered to the pelvis. A pelvic boost HypoFx EBRT consisting of 7 fractions of radiation given at a dose of 2.5 Gy per fraction that will be delivered to site(s) of gross disease of at least 1.0 cm in size. An additional boost total dose of 17.5 Gy administered will be administered over a period of 1.5 to 2.0 weeks.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Pembrolizumab, a PD-1 inhibitor, blocks the PD-1 pathway to help the immune system recognize and attack cancer cells. Lenvatinib, a tyrosine kinase inhibitor, targets receptors involved in tumor growth and angiogenesis, inhibiting cancer cell proliferation and spread. Pelvic External Beam Radiation Therapy causes DNA damage in cancer cells, leading to cell death and preventing further growth. Understanding these mechanisms helps endometrial cancer patients make informed treatment decisions and comprehend how these therapies target their cancer.
