Design outcomes

Primary

MeasureTime frame
Main Objective: The purpose of this trial is to explore the clinical utility of the three investigational agents in HR+, HER2-breast cancer. LEE011 (CDK4/6 inhibitor), BKM120 (PI3K-pan class I-inhibitor) and BYL719 (PI3K-alpha specific class I inhibitor) in combination with fulvestrant. This is a multi-center, open-label Phase Ib/II study. The Phase Ib portion of the study is a dose escalation to estimate the MTD and/or RP2D for three regimens: LEE011 with fulvestrant; LEE011 and BKM120 with fulvestrant; LEE011and BYL719 with fulvestrant. The Phase II portion of the study will be a randomized study to assess the anti-tumor activity as well as safety and tolerability of LEE011 with fulvestrant to LEE011 and BKM120 with fulvestrant, and LEE011 and BYL719 with fulvestrant in patients with ER+/HER2- locally advanced or metastatic breast cancer. ;Secondary Objective: 1-Safety and Tolerability of the combinations of LEE011 with fulvestrant, LEE011 + BKM120 with fulvestrant and LEE011 + BYL719 with fulvestrant 2- To characterize plasma concentration-time profiles of LEE011, BKM120, BYL719 and fulvestrant. 3-To assess preliminary clinical anti-tumor activity ;Primary end point(s): 1-phase Ib: Dose limiting toxicities 2- phase II: Progression Free Survival per RECIST v 1.1 by local investigator assessment;Timepoint(s) of evaluation of this end point: 1-28 days 2- 36 months

Secondary

MeasureTime frame
Secondary end point(s): 1-Adverse Events (AEs), serious AEs (SAEs), changes in hematology and chemistry values, vital signs, electrocardiograms (ECGs), dose interruptions, reductions and dose intensity 2- PK parameters for LEE011, BKM120 and BYL719, including but not limited to Cmax, Cmin, Tmax, AUCtau, accumulation ratio (Racc),and Ctrough values for fulvestrant. 3- Overall Response Rate (ORR) 4- Duration of Response (DOR) 5- Progression Free Survival (PFS) (pahse l only) 6-Overall Survival (OS) - Phase II only;Timepoint(s) of evaluation of this end point: 36 months for all listed Secondary End points
