About this study

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.

Primary outcomes

  1. Fever Duration (With a Superiority Cut-off Level δ=-0,52 Days)

    Time frame: Day 8±1

    Normalization of body temperature (axillary body temperature level ≤ 36,9 °C confirmed by two consecutive measurements (morning-evening/evening-morning)) will be considered as the end of fever

Secondary outcomes

  1. Changes in Intoxication Symptoms by 3 Day of Treatment Due to Symptom Assessment Scale (SAS)

    Time frame: Day 3

    A total number of patients (NP) without symptoms due to "General intoxication symptoms" domain of the Symptom Assessment Scale (SAS) was evaluated.

    A total number of patients (NP) with mild symptoms due to "General intoxication symptoms" domain of SAS (1 point according SAS) was evaluated.

    A total number of patients (NP) with moderate symptoms due to "General intoxication symptoms" domain of SAS (2 point according SAS) was be evaluated.

    A total number of patients (NP) with severe symptoms due to "General intoxication symptoms" domain of SAS (3 point according SAS) was evaluated.

    Domain "General intoxication symptoms" includes the following symptoms:

    • altered/decreased activity;
    • altered appetite;
    • unhealthy appearance;
    • altered or interrupted sleep.

    Each symptom may be graded by the following points:

    • 0 points - absent;
    • 1 point - mild;
    • 2 points - moderate;
    • 3 points - severe.

  2. Number of Patients (NP) Without Nasal Discharge Symptom by 3 and 5 Day of Treatment, Number of Patients (NP) With Mild/Moderate/Severe Nasal Discharge Symptom by 3 and 5 Day of Treatment

    Each symptom was graded by the following points:

    • 0 points - absent;
    • 1 point - mild;
    • 2 points - moderate;
    • 3 points - severe. Number of patients (NP) without nasal discharge symptom by 3 and 5 day of treatment (score on the scale 0 point), Number of patients (NP) with mild nasal discharge symptom by 3 and 5 day of treatment (score on the scale 1 points) Number of patients (NP) with moderate nasal discharge symptom by 3 and 5 day of treatment (score on the scale 2 points) Number of patients (NP) with severe nasal discharge symptom by 3 and 5 day of treatment (score on the scale 3 points)

  3. Score on Symptoms: Nasal Discharge and Nasal Congestion/Impaired Nasal Airflow Due to Symptom Assessment Scale by 3 and 5 Day of Treatment

    Each symptom was graded by the following points:

    • 0 points - absent;
    • 1 point - mild;
    • 2 points - moderate;
    • 3 points - severe. The higher scores mean worse outcome. The maximum score is 3 points, the minimum score is 0 points.

  4. Total Score on Symptom Assessment Scale by 3 and 5 Day of Treatment

    Time frame: Day 3, Day 5

    Symptom Assessment Scale (SAS) consists of 3 domains:

    • "Nose symptoms" (nasal discharge; nasal congestion/impaired nasal airflow; sneezing);
    • "Throat and thoracic symptoms" (hoarseness; sore throat; cough).

    Each symptom may be graded by the following points:

    • 0 points - absent;
    • 1 point - mild;
    • 2 points - moderate;
    • 3 points - severe. The higher scores mean a worse outcome. The total score is the sum of points of each symptom graded in Symptom Assessment Scale. The maximum possible value of the total score is 30 points, the minimum possible value of the total score is 0 points.
