NCT ID NCT04876391
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at the long-term safety and effectiveness of the drug spesolimab for adults with hidradenitis suppurativa (HS), a painful skin condition. Participants who had already completed a previous spesolimab trial received injections every two weeks for two years. The goal was to see if the drug remains safe and helps control HS symptoms over time.
