Can a JAK inhibitor bring back hair in kids with severe alopecia?
NCT ID NCT07772492
First seen Aug 19, 2026 · Last updated Sep 09, 2026 · Updated 5 times
Summary
This trial tests whether upadacitinib, an oral medication that calms the immune system, can help children with severe alopecia areata—a condition where the immune system attacks hair follicles, causing significant hair loss. Children aged 6 to 17 with at least 50% scalp hair loss will receive either upadacitinib or a placebo for about 160 weeks. The study measures how many achieve meaningful hair regrowth and monitors safety.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- upadacitinib, an oral JAK inhibitor that reduces inflammation
- What this could lead to
- If successful, this could provide a new, approved treatment option for children with severe alopecia areata, potentially restoring significant hair growth.
- What could go wrong
- This is an early-stage test in a specific pediatric population; results may not apply to all patients, and side effects are possible. The trial is blinded and placebo-controlled, so outcomes are uncertain.
