What was measured

OS was defined as the time from date of randomization to date of death due to any cause. If a patient was not known to have died, survival was censored at the date of last known date patient alive. The OS distribution was estimated using Kaplan-Meier methodology.

Analysis population: All subjects without a PIK3CA mutation (based on central testing of hotspot-mutations in tumor tissue) who were randomized to study treatment

Groups in this outcome

PIK3CA Non-mutant Cohort by Tumor Tissue: Alpelisib + Fulvestrant

Subjects with advanced breast cancer without a PIK3CA mutation (based on central testing of hotspot-mutations in tumor tissue) treated with alpelisib (300 mg; oral; once daily) in combination with fulvestrant (500 mg; intramuscular injection on Day 1 and Day 15 of Cycle 1, and then Day 1 of each subsequent 28-day cycle)

PIK3CA Non-mutant Cohort by Tumor Tissue: Placebo + Fulvestrant

Subjects with advanced breast cancer without a PIK3CA mutation (based on central testing of hotspot-mutations in tumor tissue) treated with placebo (300 mg; oral; once daily) in combination with fulvestrant (500 mg; intramuscular injection on Day 1 and Day 15 of Cycle 1, and then Day 1 of each subsequent 28-day cycle)
