Hidradenitis Suppurativa HS is a skin condition that causes painful bumps, abscesses, scars, and tunnels in areas where the skin rubs together. This condition may start when hair follicles become damaged, triggering the immune system and allowing bacteria to worsen the symptoms. Researchers are evaluating the safety, effectiveness, and tolerance of a drug called zasocitinib in adults with moderate to severe HS compared with a placebo in this Phase 2 clinical trial. Participants will be randomly assigned to receive either zasocitinib or a placebo for the first 16 weeks in a double-blind period. After this, all participants will receive zasocitinib for an additional 36 weeks in an open-label period. The placebo capsules look like zasocitinib but contain no medicine. Treatment dosing involves a specific dose of zasocitinib labeled as Dose A. During the study, participants will visit the clinic 12 times for assessments. Researchers will monitor the percentage of participants achieving a 75% reduction in HS symptoms at week 16 as the primary outcome. They will also track safety through adverse events and other measures throughout the 56 weeks of treatment. Participants will undergo evaluations including clinical exams, questionnaires, and safety tests to understand treatment effects and tolerability.
