Botulinum Toxin-A for Hidradenitis Suppurativa

Yale University

Overview

The purpose of this research study is to determine if the medication Botulinum Toxin-A (BTX-A) is effective in treating hidradenitis suppurativa (HS)

Hidradenitis suppurativa (HS) is an auto-inflammatory disorder of apocrine sweat glands which results in painful, draining nodules within hair-bearing skin of the axillae, groin, and perineum. There is no consensus for treatment of HS and neither a medical nor surgical cure exists. Several case reports show potential efficacy of Botulinum Toxin-A (BTX-A) in inducing remission of HS however, these studies are underpowered. The objective of this study is to determine if Botulinum Toxin- A induces regression, remission, or relapse of hidradenitis suppurativa lesions.

Interventions

Normal salineDRUG

Thirty subjects with active bilateral axillary hidradenitis suppurativa will be consecutively enrolled and randomly stratified into two groups (Group 1 and Group 2). Both groups will contain five subjects each with mild, moderate, and severe disease. All participants will have 50-units of Botulinum Toxin-A (BTX-A) injected intradermally in one axilla and normal saline (NS) placebo administered in the other in a randomized, double-blinded fashion. At three months, Group 1 will receive 50-units BTX-A and NS in the same axillae as before while Group 2 will receive NS in both axillae.

Outcomes

Primary Outcomes

Change in Number of lesions

Change in number of lesions (nodules, abscesses, and fistulous tracts). Any changes in lesion count or size will be documented and subjective symptoms such as pain will be noted.

Time frame: baseline and 3 months

Secondary Outcomes

Change in Hidradenitis Suppurativa Quality of Life (HiSQOL) score

HiSQOL is a patient-reported outcome measure developed for clinical trials to address disease-specific changes in HR quality of life (HRQOL). The item scores are summed to create a total ranging from 0 to 68, with higher scores indicating more severe impact on HRQOL.

Time frame: baseline, 3 months and 6 months

Change in Duration of Effect of BTX-A in Hidradenitis Suppurativa

Subjects will be clinically evaluated at 3, 6, and 12 months to monitor qualitative and quantitative change in lesions (nodules, abscesses, fistulous tracts) and symptoms (pain, drainage, swelling, and impairment) and duration of change, if any.

Time frame: 3 months, 6 months, 12 months
