Cyclosporine versus methotrexate for children with alopecia areata

The Effectiveness of Cyclosporine Versus Methotrexate in the Treatment of Pediatric Alopecia Areata in Routine Clinical Care: a Patient Preference Trial

PHASE4 · Erasmus Medical Center · NCT07381556

This project tests whether cyclosporine or methotrexate works better as the first systemic treatment for children and teens (ages 2–17) with moderate-to-severe alopecia areata.

What this trial studies

This is a prospective, patient-preference clinical trial comparing cyclosporine (CsA) and methotrexate (MTX) in children and adolescents with moderate-to-severe alopecia areata over a treatment period up to 36 weeks, with long-term follow-up through the Pediatric Systemic Alopecia Areata Registry (STA2R-Pediatric). Participants (age 2–17) choose their preferred treatment arm unless contraindicated, and those unable to take CsA are placed in the MTX arm. Outcomes include clinical hair regrowth, safety, and durability of response in routine clinical care settings. The trial aims to fill current gaps in prospective comparative data on off-label systemic therapies used before pediatric JAK inhibitor eligibility.

Who should consider this trial

Good fit: Children and adolescents aged 2–17 with a dermatologist-confirmed diagnosis of moderate-to-severe alopecia areata who are considering systemic therapy and can attend Erasmus MC visits are ideal candidates.

Not a fit: Patients with mild alopecia areata, those already ineligible for both medications, those with contraindications to the assigned drug, or those who cannot adhere to study visits and procedures are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the results could clarify which systemic drug is more effective and safer as an initial systemic option for children with moderate-to-severe alopecia areata, helping clinicians and families make better treatment choices.

How similar studies have performed: There are limited randomized trials and mainly observational studies supporting systemic CsA or MTX in AA, so head-to-head prospective comparative data in pediatrics are largely lacking.
