Study Results: Celldex Therapeutics released topline results from a Phase 2 study of barzolvolimab for eosinophilic esophagitis (EoE), meeting the primary endpoint of mast cell depletion but showing no clinical improvement in EoE symptoms compared to placebo.
Mast Cell Depletion: The study demonstrated significant reductions in intraepithelial mast cells, with a change from baseline at Week 12 showing -36.0 for barzolvolimab versus -2.7 for placebo.
Safety Profile: Barzolvolimab exhibited a favorable safety and tolerability profile consistent with previous studies, despite the lack of clinical efficacy in improving EoE symptoms.
Future Focus: Following these results, Celldex will not pursue further development for EoE but will continue advancing barzolvolimab in other conditions, including chronic spontaneous urticaria and atopic dermatitis.
