Optimizing Intralesional Triamcinolone Dosing for Hidradenitis Suppurativa

Optimizing Intralesional Triamcinolone Dosing for Hidradenitis Suppurativa

Currently, there is limited evidence showing increased resolution of HS flares with higher doses of intralesional triamcinolone (ILTAC) as well as a difference in side effect profile between the doses. The goal of this study is to determine the efficacy of treating HS flares with ILTAC-10, ILTAC-20 and ILTAC-40 and to investigate the side effect profile for each dose.

A double-blinded, randomized, placebo-controlled study examining the relative efficacy of ILTAC-10, ILTAC-20, and ILTAC-40 versus placebo for acute flares of HS in subjects with moderate to severe HS. The duration of the study will be approximately 4 weeks for each enrolled patient and will include an initial screening/randomization/treatment visit and a 4-week follow-up period. During the initial visit, subjects who meet the study's eligibility criteria will be randomized to receive either ILTAC-10, ILTAC-20, ILTAC-40, or placebo in a 1:1:1:1 ratio. Study subjects will then receive treatment or placebo. The follow-up period will be of 4 weeks and will consist of 3 phone calls and 1 live visit, including an end of study visit on week 4 after randomization.

Inclusion Criteria:

• Age > 13 years old.
• Subject must voluntarily sign and date an informed consent, approved by an independent ethics committee / institutional review board.
• Subject is willing to comply with the procedures in this protocol.
• The subject must be diagnosed with HS and receiving care at HSC
• Subjects with Hidradenitis Suppurativa Physician Global Assessment (HS-PGA) score between 2 and 5
• The subject must have an inflamed nodule or abscess at the time of enrollment.

Exclusion Criteria:

• The subject has an HS-PGA score of 0 or 1
• The subject has received ILTAC less than 8 days prior to the initial visit.
• The subject does not have capacity to consent to the study.
• The subject is has taken systemic steroids at least 4 weeks prior to the time of enrollment.
• The subject has a known allergy or history of adverse reaction to steroids.
