Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Patients With Recovery/Improvement in Health Status.	Based on days 2-7 days of observation according to the patient's diary, and on days 3 and 7 according to the physician's examination.	On 2-7 days of observation
Secondary	Changes in Fever.	Fever changes over time (body temperature change on days 2-7 compared to baseline, based on patient diary data).	Baseline and days 2-7 of the observation
Secondary	Average Duration of Fever.	Criteria of no fever - body temperature lower than 37.0° C for 24 hours	From the time of randomization until the time of recovery/improvement (days 1-7)
Secondary	Percentage of Patients With Normal Body Temperature.	Based on patient's diary. Normal body temperature is no more than 37.0º?.	Days 2-7 of the observation
Secondary	Severity of Influenza Symptoms (Fever, Flu Non-specific and Nasal/Throat/Chest Symptoms) in Scores According to the Symptoms Severity Scale.	The symptoms severity scale includes 14 symptoms: body temperature, non-specific symptoms (headache, chills, sweating, weakness, muscle pain, drowsiness), nasal/throat/chest symptoms (runny nose, stuffy nose, sneezing, sore throat, hoarseness, cough, chest pain).; The severity of each non-specific and nasal/throat/chest symptom is scored on a 4-point scale (0=no symptom; 1=mild symptom; 2=moderate symptom; 3=severe symptom). The minimum value of each symptom is 0 points, and the maximum value is 4 points.; The absolute body temperature (in degrees Celsius) is converted to relative units (or scores) using the following scale: =37.2?=0 points; 37.3-38.0?=1 point; 38.1-39.0?=2 points; =39.1?=3 points.; The severity of symptoms is based on the physical examination of the patient by the physician on days 1, 3, and 7 and on the patient diary data on days 1-7. The minimum symptoms severity score is 0 points, the maximum score is 42 points.	On 1-7 days of observation
Secondary	Duration of Clinical Symptoms of Influenza (Fever, Non-specific Symptoms and Nasal/ Throat/ Chest Symptoms) in Days.	Duration of clinical symptoms of influenza (fever, non-specific symptoms and nasal/ throat/ chest symptoms) in days based on the result of the patient's diary data	On 1-7 days of observation

Secondary	Dynamics of Parameters of Immune Status (T-cell and B-cell Immune Response).	The concentration of regulators of the T-cell immune response (IL2, IFN -?, IL-18), and regulators of ?-cell immune response (IL-4, IL-16).	On days1, 3 and 7 of observation.
Secondary	Dynamics of Parameters of Immune Status ( IFN-a and IFN-? Production).	Level of spontaneous and induced production of IFN-a and IFN-? (in vitro).	On day 1, 3 and 7 of observation.
Secondary	Dynamics of Parameters of Immune Status (Absolute Number of Each Type of White Blood Cells and Different Lymphocyte Phenotypes).	The absolute number of each type of white blood cells (WBC): Absolut Count (AC) of leukocytes, neutrophils, lymphocytes, monocytes, eosinophils, basophils, and CD3, CD4, CD8, CD4/CD8, CD16, CD119 leukocytes.	On days 1, 3 and 7 of observation.
Secondary	Dynamics of Parameters of Immune Status (Relative Percentage of Each Type of White Blood Cells and Different Lymphocyte Phenotypes).
