What was measured

Everolimus plasma concentration-time data obtained from patients who received Phase I defined treatment will be modeled using compartmental approaches to estimate the AUC (hr\*nM) for each dose level on day 17 of course 1 and day 1 of course 2. Patients who were enrolled in the Surgical stratum but subsequently received Phase I defined treatment with PK data available will also be included in the analysis population. 5 patients from surgical stratum received dose level 1 treatment.

Analysis population: Patients with blood samples collected for pharmacokinetic studies on day 17 of course 1 and day 1 of course 2 were included. Surgical patients who received Phase I treatment with samples collected were also included in Dose Level 1. There are total 17 patients received dose level 1 treatment and 3 patients received dose level 2 treatment. Analysis population only includes treated patients with corresponding PK data available.

Groups in this outcome

Dose Level 1, Day 17 of Course 1

Patients receive ribociclib PO QD on days 1-21 of course 1 and subsequent courses and days 2-21 of course 2 at 120 mg/m2/day, and everolimus PO QD on days 3-28 of course 1 and days 1-28 of subsequent courses at 1.2 mg/m2/day. Samples are collected on Day 17 of Course 1.

Dose Level 1, Day 1 of Course 2

Patients receive ribociclib PO QD on days 1-21 of course 1 and subsequent courses and days 2-21 of course 2 at 120 mg/m2/day, and everolimus PO QD on days 3-28 of course 1 and days 1-28 of subsequent courses at 1.2 mg/m2/day. Samples are collected on Day 1 of Course 2.

Dose Level 2, Day 17 of Course 1

Patients receive ribociclib PO QD on days 1-21 of course 1 and subsequent courses and days 2-21 of course 2 at 170 mg/m2/day, and everolimus PO QD on days 3-28 of course 1 and days 1-28 of subsequent courses at 1.2 mg/m2/day. Samples are collected on Day 17 of Course 1.

Dose Level 2, Day 1 of Course 2

Patients receive ribociclib PO QD on days 1-21 of course 1 and subsequent courses and days 2-21 of course 2 at 170 mg/m2/day, and everolimus PO QD on days 3-28 of course 1 and days 1-28 of subsequent courses at 1.2 mg/m2/day. Samples are collected on Day 1 of Course 2.
