Material Changes and Clinical Results
The Company announced results from its Phase 1b/2 003 trial, an international, multi-center, open-label, dose escalation study involving 8 patients (ages 16-20) with early onset FSHD. The study assessed Resolaris at weekly doses of 0.3, 1.0, and 3.0 mg/kg over 12 weeks.

- No patients experienced a worsening of disease burden as measured by INQoL.
- Safety and Tolerability:
- Resolaris was generally well-tolerated at doses up to 3.0 mg/kg once weekly.
- No signs of general immunosuppression were observed.
- Adverse events were mild or moderate in intensity.
- Low-level anti-drug antibody signals did not result in clinical symptoms.
