Pfizer's Tilrekimig Shows Significant Skin Clearance in Phase 2
Pfizer's Phase 2 study of tilrekimig (PF-07275315) in moderate-to-severe atopic dermatitis met its primary endpoint, showing significant skin clearance at Week 16. The study reported EASI-75 rates of 62.5% for 450 mg Q2W and 58.5%-61.0% for 200-400 mg Q4W doses, compared to 19.9%-9.1% for placebo. Tilrekimig was well-tolerated, with no dose-dependent safety signals. Pfizer has initiated Phase 3 trials for tilrekimig in atopic dermatitis, asthma, and COPD.
