The patient population for this study included adults (aged ≥ 18 years) with moderate-to-severe HS. Eligible patients were required to be diagnosed at least 1 year before the baseline visit and have a total abscess and inflammatory nodule (AN) count ≥ 5 at baseline, HS lesions in ≥ 2 distinct anatomical locations, a draining fistula count ≤ 20 at baseline, and inadequate response to oral antibiotics for the treatment of HS. Patients were ineligible to participate if they had exposure to biologic agents blocking IL-12/23, IL-23, or IL-17 within the past 6 months; prior exposure to anti-TNF therapies (except those for the treatment of HS that demonstrated inadequate response); relevant medical conditions (such as hepatitis B, hepatitis C, HIV, or tuberculosis); or if they were pregnant or breastfeeding.
