Evommune's EVO756 Shows Promising Results in Treating Chronic Inducible Urticaria Through Phase 2 Trials

Evommune's Breakthrough in Treating Chronic Inducible Urticaria



On May 28, 2025, Evommune, Inc., a pioneering biotechnology company based in Palo Alto, revealed impressive top-line data from their Phase 2 trial of the investigational drug EVO756. Specifically designed to treat chronic inducible urticaria (CIndU), EVO756 is a potent and selective oral small-molecule antagonist of the mas-related G-protein coupled receptor X2 (MRGPRX2). The results indicate promising efficacy and a favorable safety profile, marking a potential game-changer for patients riddled with this condition.

Key Findings from the Trial


The results from the trial, which included 30 patients experiencing symptomatic dermographism — the most prevalent form of CIndU — were unequivocally positive. Notably, 30% of participants achieved a complete response within just four weeks of treatment. Among these, 50% had elevated IgE levels (≥100 IU/ml), a common trait among individuals with chronic urticaria. Moreover, 41% of patients experienced a clinically significant reduction in itch levels, as measured by a 2-point decrease in the itch numerical rating scale.
