Study Endpoints
Primary Endpoints
Progression Free Survival (PFS) in Patients with PIK3CA WT and PIK3CA MT Breast Cancer
Approximately 48 months

PFS is defined as the time from randomization to death or the first documented progression, whichever occurs first, confirmed by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 criteria, as determined based on blinded independent central review (BICR)

Number of participants with dose limiting toxicities
up to 28 days
Objective response rate observed in patients in the dose expansion portion
16 weeks

Number of patients for each response category, objective response rate (number of patients with a complete response (CR)) relative to the number of response evaluable patients

Secondary Endpoints
Overall Survival (OS) in Patients with PIK3CA WT and PIK3CA MT Breast Cancer
From date of randomization to the date of death due to any cause, up to approximately 48 months
Overall Response Rate (ORR) in Patients with PIK3CA WT and PIK3CA MT Breast Cancer
Up to approximately 48 months
Duration of Response (DOR) in Patients with PIK3CA WT and PIK3CA MT Breast Cancer
Up to approximately 48 months
