The recruitment for this study was permanently halted as of 07-Dec-2022 with the intent of ending the study early because of the evolving treatment landscape and changing paradigms for HER-2 positive BC therapy. This decision was not triggered by any new or unexpected safety findings. Participants in Part 1 will be allowed to continue study treatment (alpelisib in combination with trastuzumab and pertuzumab) if they are deriving clinical benefit as assessed by the investigator and after discussion with the participant and documentation in the medical record. All participants in Part 2 will be unblinded for knowledge of treatment allocation and continuity treatment planning.Participants in the experimental arm will be allowed to continue alpelisib in combination with trastuzumab and pertuzumab based on investigator's judgement and benefit/risk assessment.Participants in Part 2 who are still receiving study treatment in the control arm with alpelisib matching-placebo will not be allowed cross-over to the experimental arm. These participants will be allowed to continue on trastuzumab and pertuzumab if they are deriving clinical benefit as assessed by the investigator and after discussion with the participant and documentation in the medical record.
