Dana-Farber Cancer Institute·interventional·Posted Sep 18, 2018·Updated Jun 22, 2026

In Brief

A Phase 2 clinical trial evaluating Letrozole, Abemaciclib, and 3 other interventions for Endometrial Cancer. Currently recruiting, targeting 110 participants across 3 sites.

Detailed Summary

Interventions

Letrozoledrug

Letrozole is a hormonal therapy that works by lowering the production of estrogen in the body.

Abemaciclibdrug

Abemaciclib is a cyclin-dependent kinase (CDK) inhibitor.

LY3023414drug

LY3023414 is a potent selective inhibitor of the class I PI3K isoforms, mTOR, and DNA-PK.

Metformindrug

Metformin inhibits mitochondrial adenosine-5'-triphosphate (ATP) synthesis, resulting in activation of the AMPK (5' AMP-activated protein kinase) pathway through LKB1, eventually causing inhibition of the mTOR pathway and subsequent reduction in protein synthesis and cellular proliferation.

Gedatolisibdrug

Gedatolisib is a PI3K/AKT/mTOR (PAM) pathway inhibitor.
