This study focuses on individuals living with Hidradenitis Suppurativa, a long-term skin condition that causes painful lumps under the skin. These lumps, known as abscesses or inflammatory nodules, often appear in areas where skin rubs together, such as the armpits or groin. The purpose of the study is to evaluate the efficacy and safety of a study drug called BFB759.

Participants in this research will be assigned to receive either BFB759 or a placebo through a subcutaneous injection, which is a shot given into the fatty layer of tissue just under the skin. This is a double-blind study, meaning that neither the participants nor the researchers will know which substance is being administered during the trial. The study is randomized, so the assignment of the treatment is decided by chance.

During the course of the study, the effects of the medication will be monitored over time. Researchers will look at changes in the number of skin lumps and track any adverse events, which are unexpected medical problems or side effects that may occur during treatment. The study will observe how the skin responds to the different doses of the medication compared to the placebo.
