Summary
This study was a multicenter, randomized, double-blind, placebo-controlled Phase III study to determine the efficacy and safety of treatment with Buparlisib plus Fulvestrant vs. Placebo plus Fulvestrant in postmenopausal women with hormone Receptor-positive (HR-positive), human epidermal growth factor receptor 2-negative (HER2-negative), aromatase inhibitor (AI)-treated, locally advanced or metastatic breast cancer whose disease progressed on or after mammalian target of rapamycin inhibitor (mTORi)-based treatment. Patients were randomized in 2:1 ratio to treatment with buparlisib 100 mg daily in combination with fulvestrant 500 mg or placebo daily in combination with fulvestrant 500 mg. Randomization was stratified according to visceral disease status (present or absent).
