Top-line data from the Reveal-2 phase III trial of elegrobart to treat chronic thyroid eye disease (TED) drove Viridian Therapeutics Inc.’s stock up by 33.6%, positioning the company for a BLA filing in the first quarter of 2027.

ORR included those with both proptosis and Clinical Activity Score response, defined as no worsening from baseline in the study eye, without deterioration in the fellow eye.
