Summary

This study looks at the long-term safety and effectiveness of a drug called sonelokimab for people with moderate to severe hidradenitis suppurativa (HS), a painful skin condition. About 835 adults and teens who completed an earlier sonelokimab study will receive the drug for an extended period. The goal is to see if the drug remains safe and helps control HS symptoms over time.
