About

The purpose of this study is:

• To obtain additional data on therapeutic efficacy of Anaferon for children in the treatment of influenza and acute respiratory viral infections in children

Full description

The study will enroll outpatient subjects of both sexes aged 3-12 years with clinical manifestations of influenza/Acute Respiratory Viral Infections (ARVI), including fever

≥ 38.0°С having an appointment with a doctor within the first day after the illness onset.

Тhe physician will collect medical history information, perform an objective examination, record the concomitant therapy, and obtain nasal swab specimens for a rapid diagnostic influenza test. If the swab is positive, the doctor shall obtain swab specimens from the nasal cavity and oropharynx (nasopharyngeal swab) for a subsequent real time reverse transcription-polymerase chain reaction (RT-PCR) to determine the viral load of influenza A and/or B virus. If the swab is negative for influenza the doctor shall collect a nasopharyngeal swab for a subsequent PCR test for other respiratory viruses.

If inclusion criteria are met and exclusion criteria are absent at visit 1 (Day 1), the patient will be enrolled in the trial and randomized into one of the two groups: group 1 patients will take Anaferon for children following a 5-day regimen; group 2 patients will receive Placebo using the Anaferon for children 5-day regimen. The parent/adopter of patient will receive a diary where they should record the child's axillary temperature data in the morning and evening, and score the severity of symptoms.

The subject will be monitored for 14 days (screening, randomization - 1 day, treatment - 5 days, follow-up - 1 day; late-scheduled phone "visit" - day 14).

At Visits 2-4, the physician will document objective examination data; obtain nasopharyngeal swabs from subjects with positive influenza tests for subsequent RT-PCR to determine the viral load and its reduction in the course of treatment; monitor the prescribed and concomitant therapy, and check the patient's diary data. The phone "visit" will be made to elicit information from the parents regarding the patient's general health, presence/absence of secondary bacterial/viral complications, and use of antibacterial drugs.

Interim statistical analysis is stipulated by the study protocol. Interim analysis will be performed using the data obtained from the examination and treatment of the protocol-defined number of patients who completed the study. Based on the expected effect, the minimum required Particular Per Protocol (pPP) sample size will be 254 patients (127 subjects in each group - Anaferon for children and Placebo).
