NCT ID NCT04856917

First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 1 time

Summary

This Phase 2 trial tested a drug called imsidolimab (ANB019) in 123 people with moderate to severe acne. The drug is a lab-made antibody designed to reduce inflammation. Researchers measured how much facial acne lesions decreased over 12 weeks compared to a placebo. The goal is to see if this treatment is safe and effective for acne.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

imsidolimab (ANB019), a lab-made antibody

What this could lead to

If it works, this could offer a new treatment option for people with moderate to severe acne who don't respond to current therapies.

What could go wrong

This is an early Phase 2 trial with only 123 participants, so results may not apply to everyone. The drug may not reduce acne better than placebo, and side effects are still being studied.
