简要总结
Purpose of the study:
• To obtain additional data on the efficacy and safety of Anaferon in the treatment of acute respiratory viral infections.
详细描述
Design: a multicenter, double-blind, placebo-controlled, parallel-group randomized trial.
The study will enroll patients of either gender aged 18-70 years old with clinical manifestations of ARVI within the first day after the onset of the disease. Signed information sheet for patient will be obtained from all participants prior to the screening procedures. Medical history, concomitant medication, thermometry, patient examination by a doctor, assessment of ARVI symptoms severity will be performed at screening visit.
The nasopharyngeal swabs will be performed for Real-time reverse transcription polymerase chain reaction (PCR) assay to confirm viral etiology of ARVI and to verify respiratory viruses prior to the therapy.
If a patient meets all inclusion criteria and does not have any exclusion criteria, at Visit 1 (Day 1) he/she will be randomized into one of two groups: the 1st group patients will take Anaferon according to the dosage regimen until the end of the study; the 2nd group patients will take Placebo according to Anaferon dosage regimen until the end of the study.
The patients will be provided with a patient diary (paper or electronic) where daily they will record axillary body temperature (using a Geratherm Classic thermometer) and each ARVI symptom severity twice a day (in the morning and in the evening). In addition, antipyretic administration (if applicable) as well as any possible worsening of the patient's condition (if applicable, for safety evaluation/AEs documentation) will also be recorded in a patient diary. An investigator will provide the instructions on filling out the diary and will help the patient to make first records of ARVI symptom severity and body temperature in the diary.

研究组 & 干预措施
Anaferon
1 tablet per administration. Day 1: 1 tablet every 30 minutes for the first 2 hours, followed by 3 more tablets taken at regular intervals through the rest of the day.
Days 2-5: 1 tablet 3 times a day. The drug is taken out of the meal (in the interval between meals or 15-30 minutes before eating), keep the tablet in the mouth, without swallowing, until completely dissolved.
干预措施: Anaferon (Drug)
Placebo
Placebo using Anaferon regimen until the end of the study.
干预措施: Placebo (Drug)
结局指标
主要结局
Time to Resolution of Acute Respiratory Viral Infection (ARVI) Symptoms.
时间窗: On days 1-7 of the observation period.
Based on a patient diary. ARVI is clinically diagnosed and/or Real-time reverse transcription polymerase chain reaction (PCR) confirmed. Criteria of resolution of ARVI symptoms: body/axillary temperature ≤37.30С for 24 hours (without subsequent increase within the observation period) + absence/presence of general ARVI symptoms with ≤2 points of Total Severity (TS) score according to the 4-point scale for each of 14 ARVI symptoms (0 = no symptom; 1 = mild symptom; 2 = moderate symptom; 3 = severe symptom). ARVI symptoms are body temperature, 6 nonspecific/flu-like symptoms, and 7 nasal/throat and chest symptoms. Absolute body temperature (in degrees Celsius) is converted to arbitrary units (or scores) using the following scale: ≤37.30С=0 points; 37.4-38.00С=1 point; 38.1-39.00С=2 points; ≥39.10С=3 points. TS ranges from 0 to 42 (higher scores mean a worse outcome).
次要结局
- ARVI Severity.(On days 1-6 of the observation period.)
- Percentage of Patients With Resolution of ARVI Symptoms (Clinically Diagnosed and/or PCR-confirmed).(On day 2, 3, 4, 5, and 6.)
- Time to Resolution of ARVI (PCR-confirmed) Symptoms.(On days 2-6 of the observation period.)
- Percentage of Patients With Resolution of ARVI Symptoms (PCR-confirmed).(On day 2, 3, 4, 5, and 6.)
- Dosing Frequency of Antipyretics if Indicated.(On day 1, 2, and 3.)
