简要总结
In the phase Ib, the primary purpose is to establish the maximum tolerated dose (MTD)(s)/recommended phase ll dose (RP2D) and schedule of LEE011 and MEK162 orally administered combination. Once the MTD(s)/RP2D have been determined for each tested schedule, additional patients will be enrolled in the phase II portion of the study at the RP2D on the chosen schedule in order to assess the anti-tumor activity of the combination in addition to continued evaluation of safety.

研究组 & 干预措施
Phase Ib
The phase Ib is the dose escalation part where successive cohorts of 3-6 newly enrolled patients receiving various dose pairs considering the recommendation from an adaptive BLRM incorporating the EWOC principle until MTD(s)/RP2D is defined. If multiple alternate dosing schedules are explored in parallel, the allocation of patients will proceed in an alternating fashion. Approximately 40 patients are expected to be treated during the phase Ib part of the study.
Dosing Schedule 1: MEK162 administered orally twice daily on a continuous dosing schedule. LEE011 administered orally once daily for 21 days followed by a 1 week break (28-day cycle).
Dosing Schedule 2: MEK162 administered orally twice daily and LEE011 administered orally once daily for 3 weeks followed by a 1 week break (28-day cycle).
Dosing Schedule 3: MEK162 administered orally twice daily and LEE011 administered once daily for 2 weeks followed by a 1 week break (21-day cycle).

Phase II
The Phase II part will begin once the MTD(s)/RP2D have been determined in the Phase Ib in order to assess antitumor activity of the LEE011and MEK162 combination. Patients enrolled in the Phase II part of the study are required to have measurable disease. Approximately 40 patients will be treated in this part.
Phase II part will begin at the RP2D on the chosen schedule in order to assess antitumor activity of the LEE011 and MEK162 combination.

结局指标
主要结局
Number of Dose Limiting Toxicities (Phase Ib)
时间窗: first 28 days of treatment
To estimate the maximum tolerate doses (MTDs) and/or identify the RP2D and schedule of LEE011 and MEK162 combination. A dose-limiting toxicity (DLT) was defined as an AE or clinically significant abnormal laboratory value assessed as unrelated to disease, disease progression, inter-current illness, or concomitant medications that occurred within the first cycle of treatment with ribociclib and binimetinib.
Objective Response Rate (ORR) (Phase II)
时间窗: Approximately 12 months after the FPFV
ORR is the proportion of patients with best overall response of complete response (CR) or partial response (PR) by month 2 assessed according to RECIST 1.1 criteria. ORR is done to describe the anti-tumor activity of LEE011 and MEK162 combination. The primary analysis of the ORR was based on the Investigator's assessment of overall lesion responses per RECIST 1.1.
