A Phase Ib/II Study of LEE011 in Combination With Fulvestrant and BYL719 or BKM120 in the Treatment of Postmenopausal Women With Hormone Receptor Positive, HER2 Negative Locally Recurrent or Advanced Metastatic Breast Cancer
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 was planned to 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.
Approximately 216 adult women with ER+/HER2- locally advanced or metastatic breast cancer
were planned to be enrolled.

On 31-May-2016 Novartis's made the decision decision to not open the Phase II portion of the
study, for business reasons. Sufficient data had already been collected and no additional
data for the triplet combinations was needed. As a result, the Phase II portion of the trial
was not opened.
