What this trial studies
This phase 3 interventional trial compares tilrekimig with dupilumab and placebo in adults and adolescents with moderate-to-severe atopic dermatitis. Participants are randomly assigned in a 2:2:1 ratio during a 24-week initial treatment period to receive tilrekimig, dupilumab, or placebo, followed by continued assessment up to 52 weeks. The study will evaluate safety, tolerability, and how the treatment affects the skin and symptoms over time. Key eligibility includes age 12 or older, chronic eczema for at least a year, and insufficient response to topical therapies. Primary locations are research sites in Birmingham, AL, and Phoenix, AZ, with Pfizer as lead sponsor.
Why it matters
Potential benefit: If successful, tilrekimig could become a new option for people with moderate-to-severe eczema who have not responded to standard topical treatments.
How similar studies have gone: The trial builds on prior approaches in this disease area, with prior biologics showing benefit in similar populations, though tilrekimig’s results are not yet known.
