Topical roflumilast 0.3% foam for hidradenitis suppurativa

An Open Label Study for Evaluating Safety & Efficacy of Topical Roflumilast 0.3% Foam as a Mono or add-on Therapy in the Treatment of Hidradenitis Suppurativa With Correlative Analysis.

Phase 2 Interventional Tulane University · NCT07077902

This will test whether applying roflumilast 0.3% foam once daily helps people with mild hidradenitis suppurativa on its own and helps control flares or maintenance when added to treatment for those with moderate-to-severe disease.

What this trial studies

This is an open-label phase 2a study of daily topical roflumilast 0.3% foam in adults with hidradenitis suppurativa. Patients with Hurley stage I disease will use the foam as monotherapy, while patients with Hurley stage II or III and active disease will apply the foam in addition to a stable systemic or other regimen. The study will track safety, tolerability, and clinical response and will perform correlative gene expression profiling using RNA from tape-strip samples taken before and after treatment. Outcomes will focus on changes in skin inflammation markers and clinical signs over the treatment period.

Who should consider this trial

Good fit: Adults (18+) with a clinical diagnosis of hidradenitis suppurativa who are Hurley stage I (for monotherapy) or Hurley stage II/III with active disease and on a stable treatment regimen for at least three months are ideal candidates.

Not a fit: People who are pregnant, unable to apply topical medication, not meeting the lesion-count diagnostic criteria, or who have recently changed systemic therapy are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, this could offer an effective topical option to reduce lesions and flares while avoiding added systemic side effects.

How similar studies have performed: Topical and systemic PDE4 inhibitors have shown promise in other inflammatory skin diseases and topical roflumilast has been explored in related conditions, but its use specifically in hidradenitis suppurativa is relatively novel.

* Patients must be candidate for topical therapy defined by active Hurley stage I or Hurley stage II/III with active disease after an adequate trial of systemic antibiotics/hormonal/immunomodulatory or biologic therapy.

* History of any clinically significant (as determined by the investigator) cardiac, endocrinologic, pulmonary, neurologic, psychiatric, hepatic, renal, hematologic, immunologic, or other major uncontrolled disease.
* Any condition, including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study.
