Summary

This study tests a daily pill called ritlecitinib for people with moderate to severe hidradenitis suppurativa (HS), a condition causing painful red skin lumps. About 240 adults who haven't been helped by antibiotics will receive either the drug or a placebo for 16 weeks. Researchers will check if the drug safely reduces skin symptoms.
