New drug shows promise for painful skin condition in large trial
NCT ID NCT04242446
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a drug called bimekizumab in 505 adults with moderate to severe hidradenitis suppurativa, a chronic skin condition that causes painful lumps. The main goal was to see if the drug reduces the number of inflamed lumps by at least half after 16 weeks, compared to a placebo. The trial is complete and aims to find a better treatment option for this hard-to-manage disease.
