Ribociclib with Carboplatin and Paclitaxel in Treating Patients with Recurrent Ovarian, Fallopian Tube, or Primary Peritoneal Cancer

Trial Status: Active

This phase I trial studies the side effects and best dose of ribociclib with carboplatin and paclitaxel in treating patients with ovarian, fallopian tube, or primary peritoneal cancer that has come back. Ribociclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as carboplatin and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ribociclib with carboplatin and paclitaxel may work better in treating patients with ovarian, fallopian tube, or primary peritoneal cancer.

I. To determine the maximum tolerated dose (MTD) of ribociclib (LEE-011) with carboplatin + paclitaxel chemotherapy in platinum-sensitive recurrent ovarian cancer.


I. To observe and record anti-tumor activity.

II. Determine the response rate (RR) and progression-free survival (PFS) of ribociclib (LEE-011) with platinum + taxane followed by maintenance ribociclib (LEE-011).

III. Further characterize the safety profile of ribociclib (LEE-011) with platinum + taxane in recurrent platinum-sensitive ovarian cancer.

IV. To correlate RR and PFS with Rb mutational status and NFAT4 nuclear localization levels


Patients receive ribociclib orally (PO) daily on days 1-4, 8-11, and 15-18 and carboplatin intravenously (IV) and paclitaxel IV on days 1, 8, and 15. Treatment repeats every 28 days for 6 cycles in the absence of disease progression or unacceptable toxicity. After 3 weeks of last dose of carboplatin and paclitaxel, patients who meet the maintenance therapy criteria receive ribociclib PO daily on days 1-21. Cycles repeat every 28 days in the absence of disease progression or unexpected toxicity.

After completion of study treatment, patients are followed up every month for 18 months.
