Overview
Brief Summary
This is a prospective interventional Phase II multi center study, open label, preceded by a retrospective non-interventional period, to assess the long-term safety and efficacy of alpelisib, in pediatric and adult participants with PROS.
Detailed Description
The study will enroll males and females aged ≥2 years who previously participated in EPIK-P1 study and who continued to receive treatment with alpelisib after the cut-off date used in EPIK-P1 (NCT04285723). The study has an initial retrospective period and a subsequent prospective period. The retrospective period, is a non-interventional study period and will start one day after the EPIK-P1 data cut-off date (i.e. 10-Mar-2020). It will end the day before the first interventional dose of alpelisib is administered in the prospective period of this study (Day -1). Key safety and efficacy information that was previously collected as per local medical practice and recorded in the medical charts of eligible participants will be longitudinally abstracted. The prospective period, is an interventional study period and will start on the day of the first interventional dose administration in the prospective period. It will end after all participants have completed at least 5 years of treatment in the prospective period of the study or discontinued earlier, whichever occurs earlier. During this study period, safety and efficacy data will be prospectively collected following a structured plan that is common to all participants.
