This open-label extension study will evaluate the long-term effects of GB002 (seralutinib) in subjects who previously participated in a GB002 PAH study.
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.
Gossamer Bio (GOSS) is the sponsoring company for this trial. BiotechSign currently grades this company B (77/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
