Brief Title: Study of LEE011, BYL719 and Letrozole in Advanced ER+ Breast Cancer
Official Title: A Phase Ib/II, Multicenter Study of the Combination of LEE011 and BYL719 With Letrozole in Adult Patients With Advanced ER+ Breast Cancer
Study ID: NCT01872260
Brief Summary: The purpose of this trial is to inform the future clinical development of the two investigational agents in ER+ breast cancer, LEE011 (CDK4/6 inhibitor) and BYL719 (PI3K-alpha inhibitor). This is a multi-center, open-label Phase Ib study. The Phase Ib dose escalation will estimate the MTD and/or RP2D for three regimens: two double combinations, LEE011 with letrozole and BYL719 with letrozole, followed by triple combinations of LEE011 + BYL719 with letrozole (Arms 3 and 4). The Phase Ib dose escalation part will be followed by Phase Ib dose expansions to further characterize the safety, tolerability, PK and preliminary clinical anti-tumor activity of the combinations. Optional crossover for patients who have progressed while on dose escalation or dose expansion with doublet treatment on Arms 1 or 2 to be treated with the triplet combination (Arm 3) after the determination of the RP2D for Arm 3; is no longer permitted after protocol amendment 6. Approximately 270 adult women with ER+/HER2- locally advanced or metastatic breast cancer will be enrolled.
