Clinical Trial Summary

The purpose of this study is is to demonstrate superiority of Polyoxidonium, nasal and sublingual spray, 6 mg/ml over placebo in children aged from 1 to 12 years with acute respiratory viral infections. This is a multicenter prospective, randomized, double-blind, placebo-controlled, parallel-group phase 3 study.

Description:

This is a multicenter prospective, randomized, double-blind, placebo-controlled, parallel-group phase 3 study to evaluate efficacy of Polyoxidonium spray 6 mg/ml on acute respiratory viral infections symptoms in children population. A study will last for 13 days (maximum) for each participant and will include 6 visits: Day 0 (Screening), Day 1, Day 3, Day 5, Day 8 ±1, Day 12 ±1. Express tests will be performed at the screening visit to exclude subjects with influenza or streptococcal infection. All eligible subjects will be treated with Polyoxidonium spray 6 mg/ml or placebo spray for 7 days. Clinical blood and urine tests will be performed at days 0 and 8 ±1. Symptom Assessment Scale (SAS) will be filled in at days 0, 1, 3, 5 and 8 ±1. Integrative Medicine Outcome Scale (IMOS) will be filled in by investigator and a parent/adopter at day 8 ±1. Adverse events information will be collected at days 1, 3, 8 ±1 and 12 ±1.
