Study Summary

This trial looks at a small protein molecule (izokibep) to treat Hidradenitis Suppurativa, a chronic skin condition. It includes people who haven't tried TNFi and those who couldn't tolerate it.

Who is the study for?
This trial is for adults aged 18-75 with active Hidradenitis Suppurativa (HS), who've had it for at least 6 months, and have at least 5 abscesses or nodules. Participants must not have a high count of draining fistulas, other interfering skin conditions, recent surgeries, certain infections like HIV or TB, uncontrolled diseases, risk of self-harm, chronic pain unrelated to HS, cancer in the last 5 years or signs of IBD.Check my eligibility
What is being tested?
The study tests Izokibep—a molecule targeting interleukin 17A—against a placebo in people with HS. It includes those new to TNF inhibitors and those who didn't respond well to them. Participants will be randomly assigned to receive either Izokibep or a placebo while monitoring their condition.See study design
What are the potential side effects?
Potential side effects may include reactions related to immune system changes due to interleukin inhibition such as increased infection risk and possibly inflammation-related symptoms; however specific side effects are not listed.
