Phase III Study of BKM120/Placebo With Fulvestrant in Postmenopausal Patients With Hormone Receptor Positive HER2-negative Locally Advanced or Metastatic Breast Cancer Refractory to Aromatase Inhibitor
Summary
This study was a multi-center, randomized, double-blind, placebo controlled Phase III study to determine the efficacy and safety of treatment with buparlisib plus fulvestrant versus fulvestrant plus placebo in postmenopausal women with hormone Receptor-positive (HR-positive), human epidermal growth factor receptor 2-negative (HER2-negative), locally advanced or metastatic breast cancer (MBC) whose disease has progressed on or after aromatase inhibitor (AI) treatment.

Outcome
Met primary endpoint
registry analysis (other test); BKM120 100mg + Fulvestrant vs Placebo + Fulvestrant; p <0.001; Hazard Ratio (HR) 0.78 (95% CI 0.67 to 0.89); Log Rank NCT01610284 ↗
paper In patients with known PI3K status (n=851), median progression-free survival was 6·8 months (95% CI 5·0-7·0) in the buparlisib group vs 4·5 months (3·3-5·0) in the placebo group (HR 0·80 [95% CI 0·68-0·94]; one-sided p=0·0033). PMID 28576675 ↗
paper In PI3K pathway-activated patients (n=372), median progression-free survival was 6·8 months (95% CI 4·9-7·1) in the buparlisib group versus 4·0 months (3·1-5·2) in the placebo group (HR 0·76 [0·60-0·97], one-sided p=0·014). PMID 28576675 ↗
