Veligrotug, an anti-IGF-1R antibody, showed positive results in a phase 3 trial for active thyroid eye disease (TED), meeting primary and secondary endpoints. The therapy demonstrated substantial improvements in proptosis, clinical activity score, and diplopia after five infusions, with a rapid onset of action and generally well-tolerated side effects. Viridian Therapeutics plans to submit a biologics license application for veligrotug by the second half of 2025.
