You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 76 participants in total. It began in 2024-07-11 with a primary completion date of 2028-08-17.

Brief Summary

This is a prospective, randomized, double-blind, placebo-controlled clinical trial. The study will take place at four sites.

All subjects must have evidence of hair regrowth within the last 7 years of their last episode of hair loss; and have screening IgE ≥200 and/or have personal and/or familial history of atopy. Study participation will be up to 124 weeks, consisting of: a screening period of up to 4 weeks; a 48-week placebo-controlled period; a 48-week open-label extension period; followed by a 24-week follow-up period.
