Trial Summary

What is the purpose of this trial?

This phase 2a trial will evaluate the safety and efficacy of EVO756 in subjects with chronic inducible urticaria, including symptomatic dermographism and cold urticaria.

Will I have to stop taking my current medications?

You may need to stop taking certain medications, like antihistamines, to participate in this trial.

What makes the drug EVO756 unique for treating chronic urticaria?

EVO756 is unique for chronic urticaria as it may offer a novel approach compared to traditional treatments like antihistamines and corticosteroids, which are often used but may not be effective for all patients. While the specific details of EVO756's mechanism are not provided, it could potentially target the underlying autoimmune aspects of chronic urticaria, similar to newer immunomodulatory drugs that have been explored for this condition. ^{1 2 3 4 5}

Findings from Research

Chronic urticaria is often an autoimmune disorder, with autoantibodies found in about half of patients, leading to a more aggressive treatment approach that includes immunomodulatory drugs.

First-line treatment involves non-sedating antihistamines, with corticosteroids used for severe cases; remission can be achieved in 20-50% of patients unresponsive to antihistamines, but long-term corticosteroid use should be minimized to reduce side effects.

Chronic urticaria: a role for newer immunomodulatory drugs? Tedeschi, A., Airaghi, L., Lorini, M., et al.[2018]

The updated WAO position paper highlights significant advancements in understanding chronic urticaria's causes and the effective use of biologics like omalizumab for patients with severe cases.

This review aims to provide simplified guidance for general practitioners worldwide, incorporating the latest information on the diagnosis and management of urticaria and angioedema, while not replacing existing national and international guidelines.
