Study Assessing the Efficacy and Safety of Alpelisib Plus Fulvestrant in Men and Postmenopausal Women With Advanced Breast Cancer Which Progressed on or After Aromatase Inhibitor Treatment.

Summary

To determine whether treatment with alpelisib plus fulvestrant prolonged progression-free survival (PFS) compared to fulvestrant and placebo in men and postmenopausal women with hormone receptor positive (HR+), human epidermal growth factor receptor-2 (HER2)-negative advanced breast cancer, who received prior treatment with an aromatase Inhibitor (AI) either as (neo)adjuvant or for advanced disease.
