A Study of IL4Rα Monoclonal Antibody in Patients With Seasonal Allergic Rhinitis

Официальное название

A Randomized, Double-Blind, Placebo-Controlled, Multicenter Phase III Clinical Trial to Evaluate the Efficacy and Safety of GR1802 Injection in Combination With Background Therapy in Patients With SAR

Обзор

Allergic rhinitis (AR) is a non-infectious chronic inflammatory disease of the nasal mucosa mainly mediated by immunoglobulin E after exposure to allergens in atopic individuals. The typical symptoms of AR are paroxysmal sneezing, watery rhinorrhea, itching, and nasal congestion, which may be accompanied by ocular symptoms, including eye itching, tearing, redness, and burning sensation, which are more common in patients with hay fever allergies.
