This is a prospective Phase II multi-center study with an initial 16-week, randomized, double-blind, placebo-controlled period, followed by two extension periods to assess the efficacy, safety and pharmacokinetics (PK) of alpelisib in pediatric and adult patients with PIK3CA-related overgrowth spectrum (PROS)
Phase 2 trials begin testing efficacy in a larger patient group (100–300). This is often where biotech binary events occur — positive Phase 2 data can significantly advance a company's pipeline narrative, while failures can be terminal for a program.
Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.
Novartis AG (NVS) is the sponsoring company for this trial. BiotechSign currently grades this company D (36/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
