Industry Context

The announcement highlights Viridian's progress in the competitive landscape of thyroid eye disease and autoimmune therapies, with a focus on developing differentiated, best-in-class treatments. The company is leveraging its expertise in antibody discovery and protein engineering to advance multiple candidates in the clinic.

Comparison to Industry Standards

• The positive Phase 3 results for veligrotug are comparable to, and in some cases exceed, the efficacy seen with teprotumumab, the current standard of care for TED.
