Is this trial a fit for you?

Likely a good fit

Adults and adolescents with HS of at least six months' duration who have Hurley stage I–III disease with ≥4 abscesses/inflammatory nodules across ≥3 body areas and estimated treatment BSA >20%, and who can avoid prohibited antibiotics and pregnancy during the study.

Probably not a fit

People with small localized HS lesions, uncontrolled serious medical conditions, other confounding skin disorders, abnormal lab values, pregnancy, or who cannot stop prohibited medications are unlikely to benefit or be eligible.

What this trial studies

This Phase 1 interventional study applies ruxolitinib cream using a maximal-use regimen to measure safety, tolerability, and systemic exposure in participants with hidradenitis suppurativa. Eligible participants must have had HS for at least six months, at least four abscesses or inflammatory nodules affecting three or more anatomical areas, and estimated treatment body surface area greater than 20%. Participants agree to avoid topical or systemic antibiotics for HS during the treatment period and follow contraception requirements. The study is conducted at dermatology research sites in Arizona and California with in-person visits for treatment and monitoring.

Why it matters

Potential benefit: If safe, this could enable a topical option for treating widespread HS lesions with potentially fewer systemic side effects than oral therapies.

How similar studies have gone: Topical ruxolitinib has shown benefit in conditions like atopic dermatitis and vitiligo, while systemic JAK inhibitors have shown some activity in HS, but maximal-use topical ruxolitinib for widespread HS is a novel application with limited prior data.
