Tirzepatide in Obesity-Driven Endometrial Cancer

What this study is testing ClinicalTrials.gov NCT07065552 ↗

Description as written by the study sponsor.

LCCC2415 examines the antiproliferative effect of tirzepatide on the endometrium of endometrial cancer (EC). This is a pre-operative window clinical study. Endometrial biopsy samples from patients before tirzepatide treatment will be compared to their post-intervention hysterectomy specimens. If archival tissue is unavailable, a fresh biopsy will be taken before tirzepatide treatment. Post-intervention tissue will be collected from the hysterectomy specimen. The hypothesis is that tirzepatide's anti-tumorigenic effects are due to both an improvement in the host's metabolic milieu (indirect effect) and a direct effect on the EC tumor microenvironment via the inter-related pathways of insulin, lipid, and mTOR signaling. Therefore, tirzepatide may be an innovative approach to effectively induce weight loss and inhibit tumor growth in EC, the most obesity-driven of all cancers.

Treatments tested

• Tirzepatide Drug

  Tirzepatide will be administered once weekly, subcutaneously, and patients will be taught how to administer this drug at home. Patients will be started on a dose of 5 mg tirzepatide weekly for four weeks prior to surgical staging. .
