NCT ID NCT07746817
First seen Aug 05, 2026 · Last updated Aug 07, 2026 · Updated 2 times
Summary
This first-in-human trial evaluates BYN-001, an antibody designed to block IL-25, a protein linked to atopic dermatitis (eczema). The study first tests the drug in healthy volunteers to assess safety and how it moves through the body, then in people with moderate to severe eczema. The goal is to see if BYN-001 is safe, tolerable, and potentially effective for treating this chronic skin condition.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- BYN-001, a humanized monoclonal antibody that blocks interleukin-25 (IL-25), given by subcutaneous injection
- What this could lead to
- If successful, this could lead to a new treatment option for moderate to severe atopic dermatitis, potentially reducing symptoms like itching and skin inflammation.
- What could go wrong
- This is an early-phase trial, so safety and effectiveness are not yet established. The drug may not work as hoped or could cause side effects.
