- Clinical Trial Results: Apogee Therapeutics announced positive 52-week maintenance data from part A of the Phase 2 APEX trial for zumilokibart (APG777) in moderate-to-severe atopic dermatitis patients, demonstrating significant durability of response with both 3- and 6-month maintenance dosing regimens, positioning it as a potential best-in-class anti-IL-13 antibody.
