Phase 1 Clinical Trial of Lenvatinib, Pembrolizumab and Hypofractionated Pelvic Radiation Therapy for pMMR Recurrent/Unresectable Endometrial Carcinoma

Is NCT05603910 recruiting? Yes, currently enrolling (Sep 2026). This Phase 1 trial studies multiple treatments including Lenvatinib and Pembrolizumab for recurrent endometrial carcinoma.

Phase 1RecruitingAaron WolfsonNCT05603910Data as of Sep 2026

Treatment: Lenvatinib · PembrolizumabThe purpose of this research study is to see if it is feasible to combine a fixed dose of pembrolizumab and a daily dose of oral lenvatinib, along with daily treatments of an abbreviated course of pelvic external beam radiation therapy, to support cancer cells in multiplying and spreading to other body sites.

Frequently asked questions

Is NCT05603910 currently recruiting?

Yes, this trial is currently recruiting patients.

Are there prior therapy exclusions?

Yes. Prior external beam radiation therapy to the vagina, pelvis, and/or abdomen disqualifies patients from enrollment.

Does this trial require MLH1?

Yes, MLH1 wild-type is a required biomarker for enrollment.

Does this trial require MSH2?

Yes, MSH2 wild-type is a required biomarker for enrollment.

Does this trial require MSH6?

Yes, MSH6 wild-type is a required biomarker for enrollment.

Are patients with MLH1 alterations eligible?

No. MLH1 loss is an exclusion criterion.

Are patients with MSH2 alterations eligible?

No. MSH2 loss is an exclusion criterion.

Is this trial open to male patients?

No. This trial enrolls female patients only.
