PFS will be assessed via a local radiology assessment according to RECIST 1.1	Once approximately 243 PFS events in this cohort had been observed, up to 32 months
Secondary	Overall Survival (OS) for Patients With PI3KCA Mutant Status	OS is defined as the time from date of randomization to date of death due to any cause.	Up to approximatly 59 months
Secondary	Overall Response Rate (ORR)	ORR is defined as the proportion of patients with best overall response of complete response (CR) or partial response (PR) based on local investigator's assessment according to RECIST 1.1.	Up to approximatly 36 months
Secondary	Time to Definitive Deterioration of Eastern Cooperative Oncology Group (ECOG) Performance Status	Deterioration of Eastern Cooperative Oncology Group (ECOG) Performance Status (PS)	Baseline, Up to approximatly 36 months
Secondary	Safety and Tolerability of Alpelisib in Combination With Fulvestrant	Safety will be determined by type, frequency and severity of adverse events per CTCAEv4.03 and type, frequency and severity of laboratory toxicities per CTCAEv4.03. Patients will be followed up for the duration of the study.	Up to approximatly 37 months
Secondary	Time to 10% Deterioration in the Global Health Status/Quality of Life (QOL) Scale Score of the EORTC QLQ-C30	Composite measure of change from baseline in the domain scores, health states, overall health status, and index values at the time of each assessment will be summarized	Up to approximatly 36 months
Secondary	Plasma Concentration-time Profile of Alpelisib Given in Combinatio With Fulvestrant and Appropriate Pharmacokinetics (PK) Parameters	Assessment of any potential impact of fulvestrant on the pharmacokinetics of alpelisib by collection of sparse and trough PK samples. PK parameters includes,but not limited to, Cmin, Cmax, t1/2, AUClast for alpelisib (and any relevant metabolites) and fulvestrant	Day 8 and Day 15 of Cycle 1, then Day 1 of Cycles 2,4, 6, 8
Secondary	PFS Based on Radiology Assessments and Using RECIST 1.1 Criteria	PFS in patients with PIK3CA mutant status and patients with PIK3CA non-mutant status as measured in ctDNA.	Baseline, Up to approximatly 36 months
Secondary	Clinical Benefit Rate (CBR)	Clinical benefit rate is defined as the proportion of patients with a best overall response of CR or PR or SD or Non-CR/Non-PD lasting more than 24 weeks based on local investigator assessment.	Up to approximatly 36 months
Secondary	Change in the Global Health Status/(QOL) Scale Score of the EORTC QLQ-C30	Composite measure of change from baseline in the domain scores, health states, overall health status, and index values at the time of each assessment will be summarized	Baseline, Up to approximatly 36 months
Secondary	Summary Statistics of Fulvestrant and Alpelisib Plasma Concentrations	Assessment of any potential impact of fulvestrant on the pharmacokinetics of alpelisib by collection of sparse and trough PK samples.	Day 8 and Day 15 of Cycle 1, then Day 1 of Cycles 2,4, 6, 8
Secondary	PFS for Patients With PIK3CA Non-mutant Status	PFS based on local radiology assessments and using RECIST 1.1 criteria in the PIK3CA non-mutant cohort	Up to approximatly 36 months
Secondary	OS for Patients With PIK3CA Non-mutant Status	OS is defined as the time from date of randomization to date of death due to any cause.	Up to approximatly 59 months
