Spots Global Cancer Trial Database for A Phase II, Two-Arm Study of Everolimus and Letrozole, +/- Ribociclib (Lee011) in Patients With Advanced or Recurrent Endometrial Carcinoma

Study Description

Brief Summary: This phase II trial studies how well everolimus and letrozole with or without ribociclib work in treating participants with endometrial cancer that has spread to other areas of the body or has come back. Ribociclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs such as everolimus and letrozole have been shown to be effective at stopping tumor growth either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ribociclib, everolimus, and letrozole may work better than everolimus and letrozole in treating participants with endometrial cancer.

Detailed Description: PRIMARY OBJECTIVE: I. To determine if the addition of ribociclib (LEE011) to everolimus and letrozole improves progression free survival in patients with advanced or recurrent endometrial carcinoma. SECONDARY OBJECTIVES: I. To determine clinical benefit and the median duration of progression-free survival (PFS) and overall survival (OS) in patients with advanced or recurrent endometrial carcinoma treated with ribociclib (LEE011), everolimus and letrozole versus everolimus and letrozole alone. II. To determine the frequency and severity of toxicities associated with ribociclib (LEE011), everolimus (RAD001), and letrozole in this cohort of patients. III. To determine the presence of a CTNNB1 mutation is associated with response to ribociclib (LEE011), everolimus (RAD001), and letrozole. IV. To determine if liquid biopsies at baseline and 8 weeks correlate with presence of a tissue mutation or response to therapy. EXPLORATORY OBJECTIVE: I. To examine the pharmacokinetic and pharmacodynamic effects of ribociclib in patients with advanced or recurrent endometrial carcinoma. OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: Patients receive ribociclib orally (PO) once daily (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. ARM II: 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. After completion of study treatment, participants are followed up at 30 days and then every 3 months.
