Summary

The available evidence describes the design of an approximately 90-participant confirmatory trial, not completed efficacy or safety results. The population is restricted to ambulatory males aged 4–18 years, with a screening rise-from-floor threshold below 10 seconds and stable glucocorticoids for at least 24 weeks. Therefore, the planned population does not directly address non-ambulatory participants. The primary assessment is at Week 73, following the stated 72-week treatment period.
