Summary

This trial tests spesolimab, a drug that may help adults with moderate to severe hidradenitis suppurativa (HS). It works by calming the immune system to reduce inflammation and heal the skin. The study aims to see if spesolimab is effective and safe for these patients.

Who is the study for?
Adults with moderate to severe hidradenitis suppurativa (HS) can join this trial. They must have had an inadequate response to antibiotics, be biologic naive or only exposed to TNF inhibitors for HS treatment, and not have used other immunosuppressive biologics. Pregnant women and those with certain allergies or a history of cancer within the last 5 years are excluded.
What is being tested?
The study tests if spesolimab helps people with HS. Participants are randomly assigned into groups receiving different doses of spesolimab or placebo via injections. After initial weekly treatments, they switch to every two weeks, and after four months, placebo groups start on spesolimab.
What are the potential side effects?
Potential side effects may include reactions at the injection site, allergic responses similar to other immune-modulating drugs like inflammation in various organs or increased infection risk; however specific side effects related to spesolimab will be monitored throughout the trial.
