Design outcomes

Primary

MeasureTime frame
Main Objective: Primary efficacy objective is to assess the efficacy of short- and long-term treatment with OM 85 vs. placebo in reducing the number of RTIs in children aged between 6 months and 5 years with recurrent RTIs associated with wLRI during the 12-month Treatment period.;Secondary Objective: Key secondary efficacy objective is to assess the efficacy of short- and long-term treatment with OM 85 vs. placebo in reducing the number of wLRIs during the 12-month Treatment period.;Primary end point(s): Primary efficacy endpoint is the rate of RTIs during the 12-month Treatment period, defined as the number of RTIs experienced by a subject relative to their time at risk during the Treatment period (Visit 2 to Visit 5).;Timepoint(s) of evaluation of this end point: after 12 months

Secondary

MeasureTime frame
Secondary end point(s): Rate of wLRIs during the 12-month Treatment period, defined as number of wLRIs experienced by a subject relative to their time at risk during the Treatment period (Visit 2 to Visit 5).;Timepoint(s) of evaluation of this end point: after 3, 6, 9, 12 months
