Study Summary

This trial will test a new medication for alopecia areata, a condition that causes hair loss. The medication will be assessed for efficacy and tolerability in children and adolescents.

Who is the study for?
This trial is for children and adolescents with alopecia areata who have experienced hair loss for less than 5 years and have more than 10% scalp hair loss without regrowth in the past 6 months. Participants must avoid UV light exposure, not be pregnant or breastfeeding, use contraception if applicable, and cannot have certain skin diseases, active infections, a history of significant psychiatric conditions or substance abuse.Check my eligibility
What is being tested?
The study tests the effectiveness of a topical treatment called squaric acid dibutyl ester (SADBE) at a concentration of 5%, compared to a placebo. It aims to assess how well SADBE works from both patient-centered outcomes and economic perspectives.See study design
What are the potential side effects?
While specific side effects are not listed here, typical reactions to topical treatments like SADBE may include skin irritation, redness, itching or burning sensation at the application site. Systemic side effects are unlikely but could occur depending on individual sensitivity.
