A Study to Assess the Efficacy and Safety of Daily OM-85 in Young Children With Recurrent Wheezing

This study is a 12-months phase 2, randomized, double-blind, placebo-controlled, multicenter study to assess the efficacy and safety of daily treatment with OM-85 compared to placebo, when given on top of standard of care treatment, in reducing wheezing/asthma like episodes (WEs) during the 6-month treatment period in children aged 6 months to 5 years with previous recurrent WEs. Patients will be randomized in a 1:1 ratio to OM-85 or placebo. The study consists of screening period (Day -20 to Day -1), a treatment period of 6 months, and an observational period of 6 months without treatment. Thus, the total duration of the study for each patient will be 12 months (±10 days) + up to 20 days for screening.
