- Study Population: 188 patients enrolled (125 veligrotug, 63 placebo); mean time since TED onset was 69.8 months.
- Proptosis (Eye Bulging):
- Responder Rate: 56% (veligrotug) vs. 8% (placebo); p < 0.0001.
- Mean Reduction: 2.34mm (veligrotug) vs. 0.46mm (placebo); p < 0.0001.
- Rapid onset observed as early as 3 weeks.
- Diplopia (Double Vision):
- Response Rate: 56% (veligrotug) vs. 25% (placebo); p = 0.0006.
- Complete Resolution: 32% (veligrotug) vs. 14% (placebo); p = 0.0152.
- Rapid onset observed as early as 6 weeks.
- Clinical Activity Score (CAS):
- Reduction to 0 or 1: 54% (veligrotug) vs. 24% (placebo); p = 0.006.
- Mean Reduction: 2.9 points (veligrotug) vs. 1.3 points (placebo); p < 0.0001.
- Overall Response: 56% (veligrotug) vs. 7% (placebo); p < 0.0001.

Investor Verification Checklist
- Verify the full statistical analysis plan and detailed safety data in the attached press release (Exhibit 99.1).
- Confirm the specific definition of "Overall Responder Rate" and its clinical relevance to regulatory bodies (FDA/EMA).
- Assess the impact of the high incidence of muscle spasms (36%) on patient quality of life and long-term tolerability.
- Review the company's cash runway and capital requirements for commercialization, as this filing does not disclose financial status.
- Monitor for subsequent filings regarding the timeline for New Drug Application (NDA) submission.
