Summary

This study tested the drug risankizumab (Skyrizi) in 214 adults with moderate to severe genital or scalp psoriasis. Participants received either the drug or a placebo for 16 weeks, then all received the drug. The goal was to see if it could clear or nearly clear the skin in these sensitive areas.
