Botulinum Toxin Blockade of Neuronal Signals to Immune Cells as a Novel Treatment for Hidradenitis Suppurativa (Botox in HS)

2026年9月8日 更新者:Sarah Whitley、University of Massachusetts, Worcester
This study will build on data from mice and humans implicating TRPV1 nociceptors in the pathogenesis of the type-17 chronic inflammatory skin disease hidradenitis suppurativa (HS). In this study, the investigators will extend data from a 12-week pilot study to rigorously test the hypothesis that botulinum toxin (BoNT) therapy reduces disease severity and relieves HS pain symptoms..

詳細な説明

This study will recruit 40 HS patients with an abscess and inflammatory nodule (AN) count ≥5 at a single body site (ex. bilateral axillae, medial thighs). Participants will be randomized 1:1 to receive placebo or 50U of BoNT per 100cm2 of skin (100U total) administered twice over a 6-month study period. Randomization will be stratified by disease stage (Hurley stage <III, III). At baseline and weeks 4, 12, and 24 disease activity and pain symptom burden will be measured using percent change from baseline in abscess and inflammatory nodule (AN) count and draining tunnel (dT) count as primary outcomes and achievement of ≥ 30% reduction from baseline in the Patient's Global Assessment of Skin Pain Numeric Rating Scale (NRS)-30 as a secondary outcome. The investigators will conduct high-frequency ultrasound measurement of HS tunnel area at baseline and weeks 4,12, and 24 to determine if BoNT therapy can reduce tunnel size. The study team will also collect punch biopsies of lesional skin from HS patients before, and 4 weeks after BoNT treatment then perform flow cytometric, transcriptomic, and microscopic analysis of skin to determine if and how nonselective inhibition of neuropeptide release diminishes HS inflammation.
