Safety and Efficacy of Adalimumab (Humira) for Hidradenitis Suppurativa (HS) Peri-Surgically

This was an interventional, randomized, double-blind (DB), placebo-controlled study. The study duration included a 30-day Screening Period, an initial 12-week DB treatment pre-surgery period (Period A), a 2-week peri-operative period with continuation of weekly DB study drug administration (Period B), and a subsequent 10-week DB treatment post-operative period (Period C). Randomization (in a 1:1 ratio) in Period A was stratified by baseline Hurley Stage (II versus III) and anatomical location of the planned surgical site (i.e., axilla versus inguinal region). The projected size of the surgical excision established by the designated surgeon during the Screening Period (calculated from a tracing of the outer perimeter onto an acetate sheet or equivalent) was recorded. In Period B, the designated surgeon measured and recorded the surface area of the actual surgery, with surgery occurring during Week 13. Surgery and post-operative management (e.g., hospitalization, surgical wound care) was per local practice. No study drug was administered at Week 24, the final study visit. Participants were able to begin commercial product (as prescribed by the participants's physician) after all Week 24 procedures were completed.
