Primary Outcome Measures :
  1. Progression-free Survival (PFS) Per Investigator Assessment in the PIK3CA Mutant Cohort [ Time Frame: Once approximately 243 PFS events in this cohort had been observed, up to 32 months ]
    PFS, defined as the time from the date of randomization to the date of the first documented progression or death due to any cause. PFS will be assessed via a local radiology assessment according to RECIST 1.1


Secondary Outcome Measures :
  1. Overall Survival (OS) for Patients With PI3KCA Mutant Status [ Time Frame: Up to approximatly 59 months ]
    OS is defined as the time from date of randomization to date of death due to any cause.

  2. Overall Response Rate (ORR) [ Time Frame: Up to approximatly 36 months ]
    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.

  3. Time to Definitive Deterioration of Eastern Cooperative Oncology Group (ECOG) Performance Status [ Time Frame: Baseline, Up to approximatly 36 months ]
    Deterioration of Eastern Cooperative Oncology Group (ECOG) Performance Status (PS)

  4. Safety and Tolerability of Alpelisib in Combination With Fulvestrant [ Time Frame: Up to approximatly 37 months ]
    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.

  5. Time to 10% Deterioration in the Global Health Status/Quality of Life (QOL) Scale Score of the EORTC QLQ-C30 [ Time Frame: Up to approximatly 36 months ]
    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

  6. Plasma Concentration-time Profile of Alpelisib Given in Combinatio With Fulvestrant and Appropriate Pharmacokinetics (PK) Parameters [ Time Frame: Day 8 and Day 15 of Cycle 1, then Day 1 of Cycles 2,4, 6, 8 ]
    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

  7. PFS Based on Radiology Assessments and Using RECIST 1.1 Criteria [ Time Frame: Baseline, Up to approximatly 36 months ]
    PFS in patients with PIK3CA mutant status and patients with PIK3CA non-mutant status as measured in ctDNA.

  8. Clinical Benefit Rate (CBR) [ Time Frame: Up to approximatly 36 months ]
    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.

  9. Change in the Global Health Status/(QOL) Scale Score of the EORTC QLQ-C30 [ Time Frame: Baseline, Up to approximatly 36 months ]
    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

  10. Summary Statistics of Fulvestrant and Alpelisib Plasma Concentrations [ Time Frame: Day 8 and Day 15 of Cycle 1, then Day 1 of Cycles 2,4, 6, 8 ]
    Assessment of any potential impact of fulvestrant on the pharmacokinetics of alpelisib by collection of sparse and trough PK samples.

  11. PFS for Patients With PIK3CA Non-mutant Status [ Time Frame: Up to approximatly 36 months ]
    PFS based on local radiology assessments and using RECIST 1.1 criteria in the PIK3CA non-mutant cohort

  12. OS for Patients With PIK3CA Non-mutant Status [ Time Frame: Up to approximatly 59 months ]
    OS is defined as the time from date of randomization to date of death due to any cause.
