AbbVie’s Zumilokibart Meets Primary Endpoint in Phase 2 Atopic Dermatitis Study
AbbVie reported that all three dose regimens of its drug zumilokibart met the primary endpoint in a Phase 2 study for atopic dermatitis, with the mid-dose showing early improvements. The drug, an anti-IL-13 monoclonal antibody, aims to offer extended dosing intervals in a crowded market valued at $20.69 billion in 2025. Secondary endpoints also supported the mid- and high-dose regimens, with safety profiles consistent with similar drugs.
