Trial Summary

What is the purpose of this trial?

This trial is testing if a daily pill called upadacitinib can help people with a painful skin condition called hidradenitis suppurativa (HS) who haven't responded to usual treatments. The study will involve adults and teenagers and will check for safety and effectiveness over time. Participants will be randomly given either the medication or a non-active pill, and their progress will be monitored through periodic medical check-ups.

Will I have to stop taking my current medications?

The trial requires stopping certain medications before starting. You must stop using prescription topical therapies for HS and systemic antibiotics at least 14 days before the trial begins. Other investigational drugs and certain cell-depleting therapies must also be stopped before participating.

How is the drug Upadacitinib unique for treating hidradenitis suppurativa?

Upadacitinib is unique because it is a selective Janus kinase (JAK)1 inhibitor, which targets specific pathways involved in inflammation, offering a novel approach for treating hidradenitis suppurativa, especially in cases resistant to conventional therapies.12345

Eligibility Criteria

Adults and adolescents with moderate to severe Hidradenitis Suppurativa (HS) who haven't improved on anti-TNF therapy can join. They must have HS in at least two areas, been diagnosed for over 6 months, and meet specific lesion counts. Excluded are those with other active skin diseases or recent use of certain drugs.

Inclusion Criteria

My skin condition affects at least one area and is moderate to severe.
I have tried at least one TNF inhibitor for HS for 12 weeks or a non-TNF biologic for 16 weeks without success, or I couldn't tolerate it.
I have HS lesions in at least two different body areas.

Exclusion Criteria

I have no active skin conditions or infections that could affect my HS assessment.
I haven't had cell-depleting therapies like rituximab in the last year or until my B cell count normalized.
I haven't taken antibiotics for HS or any chronic inflammation in the last 14 days.

Interventions

  • Upadacitinib (Janus Kinase (JAK) Inhibitor)
Trial OverviewThe trial tests Upadacitinib's effectiveness against HS compared to a placebo. It's double-blinded, so participants won't know if they're getting the drug or placebo. The study has three periods: initial treatment phase, adjustment based on results, and long-term extension for up to 68 weeks.

Findings from Research

In a case series involving 6 patients with treatment-resistant inflammatory skin conditions, the JAK inhibitors upadacitinib and tofacitinib showed promising clinical outcomes, including symptom resolution and reduced flares in conditions like dermatomyositis and hidradenitis suppurativa.
These findings suggest that JAK inhibitors may serve as effective off-label treatments for various inflammatory cutaneous disorders, warranting further research with larger patient groups to confirm their efficacy and safety.
Off-Label Use of Janus Kinase Inhibitors in Inflammatory Cutaneous Diseases.Agarwal, A., Diaz, A., Al-Dehneem, R., et al.[2023]
A systematic review of 34 publications involving 105 patients with hidradenitis suppurativa (HS) found that TNF-alpha inhibitors, particularly infliximab, led to positive treatment outcomes in 90% of cases, indicating their potential efficacy in managing this challenging skin condition.
While side effects were reported in 8 out of 105 patients, they were similar to those seen in other studies with TNF-alpha inhibitors, suggesting a manageable safety profile; however, the need for more standardized reporting and randomized controlled trials is emphasized to better understand long-term effects and optimal treatment strategies.
Treatment of hidradenitis suppurativa with tumour necrosis factor-alpha inhibitors.Haslund, P., Lee, RA., Jemec, GB.[2018]
Upadacitinib, a selective JAK1 inhibitor, demonstrated an oral bioavailability of approximately 80% for its extended-release formulation compared to the immediate-release version, based on a pharmacokinetic analysis of 11,658 plasma concentrations from 1,145 subjects across multiple studies.
The study found that while certain factors like sex and renal function can affect drug levels in the body, these variations are not expected to lead to clinically significant changes in the drug's effectiveness or safety.
