BYN-001 in healthy adults and adults with moderate to severe atopic dermatitis
Official title: A Phase 1 Randomized, Double-blind, Placebo-controlled, Single and Multiple Ascending Dose Study to Evaluate the Safety, Pharmacokinetics, and Pharmacodynamics of BYN-001 in Healthy Adult Participants and Participants With Moderate to Severe Atopic Dermatitis
Run by Bionyra Pharma · NCT07746817 · Data updated 2026-11-12
This first-in-human study tests BYN-001, a monoclonal antibody targeting IL-25, first in healthy adults and then in adults with moderate to severe atopic dermatitis to see if it is safe and how the body handles it.

Is this trial a fit for you?
✓Likely a good fit
Healthy adults aged 18-55 without significant medical conditions for Parts A and B; adults aged 18-55 with documented moderate to severe atopic dermatitis for Part C.
✕Probably not a fit
Participants with significant medical conditions or those who do not respond to or tolerate the drug may not experience direct benefit.

What this trial studies
This is a first-in-human, phase 1 trial of BYN-001, a humanized IgG1 antibody that neutralizes interleukin-25. Parts A and B enroll healthy adults in single ascending and multiple ascending dose cohorts to evaluate safety, tolerability, pharmacokinetics, pharmacodynamics, and immunogenicity under a sentinel-design with an independent Safety Monitoring Committee. Part C expands to adults with moderate to severe atopic dermatitis to explore safety and pharmacology in the target condition. BYN-001 is designed to block IL-25 and potentially reduce type 2 inflammatory signaling and pruritus. The study uses placebo-controlled comparisons and aims to define appropriate dosing for future trials.
Why it matters
Potential benefit: If successful, BYN-001 could offer a new approach to reducing inflammation and itch in atopic dermatitis and provide safety and dosing data to guide future development.
How similar studies have gone: Previous first-in-human monoclonal antibodies targeting IL pathways have shown safety and pharmacologic signals in early-stage trials, supporting exploration of BYN-001 in this population.
