Primary outcomePrimary: Percentage of Participants Achieving Hidradenitis Suppurativa Clinical Response (HiSCR) at Week 16 — 41.5; 46.8; 43.4 percentage of participants — p=0.422
Summary
The primary objective of this study is to assess the safety and efficacy of risankizumab 180 mg and 360 mg versus placebo for the treatment of signs and symptoms of moderate to severe hidradenitis suppurativa (HS) in adult participants diagnosed for at least one year before the Baseline visit.
