A Phase III Randomized, Double Blind, Placebo Controlled Study of BKM120 With Fulvestrant, in Postmenopausal Women With Hormone Receptor-positive HER2-negative AI Treated, Locally Advanced or Metastatic Breast Cancer Who Progressed on or After mTOR Inhibitor Based Treatment

Brief Overview

This study will evaluate whether the addition of daily BKM120 to fulvestrant is effective
and safe in treating patients with HR+, HER2-, AI treated locally advanced or metastatic
breast cancer who progressed on or after mTor inhibitor based treatment.
