Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To assess the proportion of patients who are alive without disease progression at 6 months based on local investigator assessment per RECIST v1.1 separately in cohort A and C (alpelisib in combination with fulvestrant) and cohort B (alpelisib in combination with letrozole) among patients with HR+, HER2-negative aBC harboring a PIK3CA mutation whose disease had progressed on or after prior treatments;Secondary Objective: To assess progression free survival (PFS) based on local investigator assessment for each cohort To assess PFS on next-line treatment (PFS2) for each cohort To assess overall response rate (ORR) and clinical benefit rate (CBR) based on local investigator assessment for each cohort To assess duration of response (DOR) in patients with confirmed complete response (CR) or partial response (PR) for each cohort. To assess Overall Survival (OS) for each cohort To evaluate the safety and tolerability of the combination for each cohort Evaluate clinical benefit as assessed by the Investigator during the Extension Phases;Primary end point(s): The percentage of patients who are alive without disease progression;Timepoint(s) of evaluation of this end point: Date of first dose to approximately 6 months | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Progression free survival (PFS) for each cohort Progression free survival (PFS) on next line treatment PFS2) for each cohort Percentage of participants Overall response rate (ORR) for each cohort Percentage of participants with clinical benefit rate (CBR) for each cohort Duration of response (DOR) Overall Survival Further secondary objectives and details are described in the protocol;Timepoint(s) of evaluation of this end point: date of first dose to up to approximately 25 months Date of first dose to date of first documented progression up to approximately 25 months Date of first dose and up to approximately 25 months Date of first dose and up to approximately 25 months Date of first documented response to first documented progression or death up to approximately 25 months | — |
