Study Summary
This study will evaluate the efficacy, safety, and pharmacokinetics of GDC-0077 in combination with palbociclib and fulvestrant compared with placebo plus palbociclib and fulvestrant in patients with PIK3CA-mutant, hormone receptor (HR)-positive, HER2-negative locally advanced or metastatic breast cancer whose disease progressed during treatment or within 12 months of completing adjuvant endocrine therapy and who have not received prior systemic therapy for metastatic disease.
