Clinical Trials

Advancing novel candidates with the highest likelihood of driving significant benefit for patients.

We’re committed to evolving immunology. Our pipeline includes programs that are targeted to address highly prevalent inflammatory diseases. Our goal is to drive meaningful advances for patients with these diseases, designing all our programs to deliver best-in-class profiles.

EVO756 is an orally administered, highly selective MRGPRX2 inhibitor being developed for patients with chronic spontaneous urticaria who remain symptomatic despite H1 antihistamine treatment. Evommune has initiated a Phase 1 clinical trial that is evaluating the safety/tolerability and preliminary activity of its MRGPRX2 antagonist inhibitor in healthy volunteers and patients with chronic spontaneous urticaria.

Chronic Spontaneous Urticaria (CSU)
Phase 1 Ongoing

EVO756-HV001 is a Phase 1 randomized, double-blind, placebo-controlled study to evaluate EVO756 in healthy adults. The study is divided into 3 parts. Part A will evaluate the safety and pharmacokinetics of single oral ascending doses of EVO756 in 6 cohorts of study participants and Part B will evaluate the safety, pharmacokinetics, and pharmacodynamics (effects on mast cells and skin reactivity) of EVO756 after 14 days of oral dosing in 3 cohorts of study participants. Part C will evaluate the safety, pharmacokinetics, and pharmacodynamics (effects on mast cells and skin reactivity, serum tryptase levels and itch) in one cohort of adults with mild chronic spontaneous urticaria.

Expanded Access Policy

Currently, Evommune’s investigational therapies are not available on an expanded access or right-to-try basis for new patients. In the event Evommune decides to consider expanded access or right-to-try use, Evommune will evaluate and respond to each request that it receives on a case-by-case basis.

We are focused on novel therapies that target the drivers of chronic inflammatory disease.
