Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Efficacy and safety of imsidolimab (ANB019) in participants with Hidradenitis Suppurativa

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase 2, multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of imsidolimab in adult participants with hidradenitis suppurativa (HS). This study will also characterize the pharmacokinetic (PK) profile of imsidolimab and explore the immune response to imsidolimab in participants with HS.
