New drug aims to calm painful skin flares in hidradenitis suppurativa
NCT ID NCT06895499
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This early-stage trial is testing a new drug called HB0043 in 15 adults with moderate to severe hidradenitis suppurativa (HS), a chronic skin condition causing painful abscesses. The drug is a bispecific antibody that targets two inflammatory proteins (IL-17A and IL-36R) to reduce inflammation. The main goal is to check safety and tolerability, with a secondary focus on whether it can reduce skin lesions by at least 50% after 12 weeks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- HB0043 (a bispecific antibody targeting IL-17A and IL-36R)
- What this could lead to
- If successful, this could lead to a new treatment option that reduces painful skin abscesses and inflammation in people with hidradenitis suppurativa.
- What could go wrong
- This is an early-phase trial with only 15 participants, so results may not apply to everyone. The drug may cause side effects or fail to show clear benefit.
