Trial Summary

What is the purpose of this trial?

This trial is testing a new drug combination for advanced or recurrent endometrial cancer. It targets patients whose cancer has spread or returned. The treatment works by blocking enzymes needed for cancer cell growth and by stopping the cells from dividing or spreading. Anlotinib is a new drug that targets multiple aspects of cancer growth.

Treatment Details

Interventions

• Everolimus
• Letrozole
• Ribociclib

Trial Overview The study is testing the effectiveness of everolimus combined with letrozole, with or without ribociclib, in treating endometrial cancer that has spread or returned. Ribociclib blocks enzymes needed for cell growth while everolimus and letrozole work by killing cells, stopping division, or preventing spread.

Participant Groups

Group I: Arm II (everolimus, letrozole) Experimental Treatment 2 Interventions

Patients receive everolimus PO QD and letrozole PO QD on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Group II: Arm I (ribociclib, everolimus, letrozole) Experimental Treatment 3 Interventions

Patients receive ribociclib PO QD, everolimus PO QD, and letrozole PO QD on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
