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.
