Title: A Phase II, Multicenter, Randomized, Double-Blind, Parallel-Group, Placebo-Controlled Study to Evaluate the Efficacy and Safety of MILR1444A in the Prevention of Allergen-Induced Airway Obstruction in Adults With Mild Allergic Asthma
Brief Summary: This is a multicenter, randomized, double-blind, placebo-controlled study designed to demonstrate the safety and efficacy of MILR1444A compared with placebo in reducing the airway reaction to an inhaled aeroallergen solution in adult patients with mild allergic asthma. The study will randomize approximately 24 patients at five study centers. In the event of patient discontinuation from the study, additional patients may be enrolled at the discretion of the Sponsor.
