The main goal of the study is to evaluate the safety and efficacy of GTX-102 in participants with Angelman syndrome.
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.
Ultragenyx Pharmaceutical (RARE) is the sponsoring company for this trial. BiotechSign currently grades this company C (60/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
