A Study to Assess the Efficacy and Safety of Daily OM-85 in Young Children With Recurrent Wheezing
PHASE2COMPLETED
This study will assess the efficacy and safety of daily OM-85 treatment compared to placebo in children aged 6 months to 5 years with recurrent wheezing.
Study details:
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.

- Up-to-date vaccination status as per applicable State or country Vaccination Requirements for school/day-care entry.
- Parents or LAR have provided the appropriate written informed consent. Written informed consent must be provided before any study-specific procedures are performed including screening procedures.
Exclusion criteria
- Known anatomic alterations of the respiratory tract.
- Wheezing documented to be caused by gastroesophageal reflux.
- Other known chronic respiratory diseases (e.g., tuberculosis or cystic fibrosis).
- Any known autoimmune disease.
- Known human immunodeficiency virus (HIV) infection or any known type of congenital or iatrogenic immune deficiency (including immunoglobulin (Ig) A deficiency).
- Known acute or chronic, clinically significant pulmonary, cardiovascular, hepatic or renal function abnormalities.
- Children born prematurely i.e., before 34 weeks of gestational age.
- Children with an abnormally low or high weight for their age and height, if this would not allow safe completion of the clinical study in the opinion of the investigator.
- Any known neoplasia or malignancy.
- Treatment with the following medications: Systemic corticosteroids within 4 weeks before study enrollment. Previous and/or concomitant immunosuppressants, immunostimulants, or gamma globulins within 6 months before study enrollment.
- Any major surgery within the last 3 months prior to study enrollment or planned during the study duration.
- Known allergy or previous intolerance to investigational drug.
- Any other clinical conditions, which in the opinion of the Investigator, would not allow safe completion of the clinical study.
- Other household members have previously been randomized in this clinical study and have not completed their 6-month treatment period.
- Inability to comply with the study requested visit schedule (e.g., expected relocation within 12 months of the screening for the study).
- Currently enrolled in or has completed any other investigational device or drug study <30 days prior to screening or receiving other investigational agent(s).

What is the study measuring?
Primary Outcome
| Measure | Description | Time Frame |
|---|---|---|
| Rate of Wheezing/Asthma like episodes (WEs) | To assess the efficacy of OM-85 in reducing the rate of WEs compared to placebo during the 6-month Treatment period in children aged 6 months to 5 years with previous recurrent WEs. | 6 Months |
Secondary Outcome
| Measure | Description | Time Frame |
|---|---|---|
| Rate of severe WEs | To assess the efficacy of OM-85 in reducing the rate of severe WEs compared to placebo during the 6-month Treatment period. | 6 Months |
| Number of WE requiring oral corticosteroid (OCS) treatment during 6-month treatment period | To assess the efficacy of OM-85 in reducing the use of oral corticosteroids for WEs compared to placebo during the 6-month Treatment period. | 6 Months |
| Number of days with WEs | To assess the efficacy of OM-85 to decrease the cumulative number of days with WEs compared to placebo during the 6-month Treatment period. | 6 Months |
| Rate of WEs and severe WEs | To assess the efficacy of OM-85 compared to placebo in reducing the rate of WEs and severe WEs during the 6-month Observational period. | From Month 6 up to Month 12 |
| Number of WE requiring OCS treatments during 6-month observational period | To assess the efficacy of OM-85 in reducing the use of oral corticosteroids for WEs vs. placebo during the 6-month observational period. | From Month 6 up to Month 12 |
| Duration in days of WEs and severe WEs | To assess the efficacy of OM-85 compared to placebo in reducing the duration of WEs and of severe WEs during the 6-month Treatment period and the 6-month Observational period. | 12 Months |
