Summary

This trial will test if everolimus, letrozole, and metformin can help control endometrial cancer that has come back or is progressing. Researchers will also study if the combination is safe.

Who is the study for?
This trial is for adults with advanced or recurrent endometrial carcinoma that's resistant to standard treatments. Participants can have had no more than two prior chemo regimens, must not be pregnant or of child-bearing potential, and should have adequate organ function. They cannot join if they've had other cancers (except certain skin cancers) in the past 3 years, known hypersensitivity to everolimus, uncontrolled brain metastases, severe liver impairment, active infections, or are on immunosuppressants.
What is being tested?
The study tests a combination of three drugs: Everolimus (blocks cancer growth proteins), Letrozole (interferes with estrogen production affecting cancer cell growth), and Metformin (commonly used for diabetes but may slow cancer by lowering insulin levels). The aim is to see if this combo controls endometrial cancer better and understand its safety profile.
What are the potential side effects?
Potential side effects include blood sugar changes due to Metformin; fatigue; increased risk of infection; hormonal changes from Letrozole; and possible organ inflammation from Everolimus. Each drug has its own set of risks which will be monitored throughout the trial.

Trial Design

1Treatment groups
Experimental Treatment
Group I: Letrozole + Metformin + RAD001Experimental Treatment3 Interventions
Patients have a 7-10 day lead in period where they take Metformin alone. The starting dose of Metformin 500 mg by mouth daily for 4 days and then increased to 500 mg by mouth twice a day. Everolimus and Letrozole added and considered the start of Cycle #1. Everolimus administered by mouth as once daily dose of 10 mg. Letrozole 2.5 mg tablet by mouth once daily. The oral dose of Everolimus should be taken together with the daily dose of Letrozole 2.5mg.
