PIK3CA-Related Overgrowth Spectrum (PROS)

This study is designed to demonstrate the efficacy and assess safety and tolerability of oral daily alpelisib in participants with PIK3CA-related overgrowth spectrum (PROS).

This is a 3-part Phase 2 randomized study evaluating the safety and efficacy of the mutant-selective PI3Kα inhibitor, zovegalisib (RLY-2608), in adults and children with PIK3CA Related Overgrowth Spectrum (PROS) and malformations driven by PIK3CA mutation. Part 1 is a dose selection, Part 2 is a basket design with exploratory single-arm cohorts for various subpopulations of participants, and Part 3 is randomized, double-blinded study vs placebo.

This study is a multi-center, open-label, single arm, phase I/II study to evaluate the safety, tolerability, pharmacokinetics and preliminary efficacy of CYH33 in patients with PIK3CA-related overgrowth spectrum (PROS) and PIK3CA-related vascular malformations (PRVM)

The purpose of this study is to provide post-trial access to alpelisib and to assess its long-term safety when administered as a single agent or in combination with other drugs. This study is intended for participants who are currently receiving alpelisib in a Novartis-sponsored clinical trial (parent study) and, in the Investigator's judgment, would benefit from continued treatment with alpelisib.

The purpose of this registration is to list Managed Access Programs (MAPs) related to BYL719, Alpelisib
