Apogee Therapeutics: Zumilokibart Phase 2 Shows 75-85% Maintain EASI-75 at One Year With Quarterly or Semi-Annual Dosing
Apogee Therapeutics announced positive 52-week Phase 2 Part A data for zumilokibart (APG777) in moderate-to-severe atopic dermatitis. In the APEX trial, 75% of patients on quarterly injections and 85% on semi-annual injections maintained at least EASI-75 (75% improvement in skin lesion severity) at one year. These maintenance rates are comparable to Dupixent and Ebglyss but with dramatically less frequent dosing — every 3-6 months versus monthly alternatives. Phase 3 trials are expected to begin in the second half of 2026.
