Acute Respiratory Viral Infection

Brief summary

The multicenter double-blind placebo-controlled randomized in parallel-group. The objective of this study is to evaluate efficacy and safety of Raphamin in the treatment of acute respiratory viral infection (ARVI) in children aged 12-18 years old.

Detailed description

Design: a multicenter, double-blind, placebo-controlled, parallel-group randomized clinical trial. The study will enroll outpatient subjects of either gender aged 12-18 old years with clinical manifestations of acute respiratory viral infection (ARVI) within the first days after the onset of the disease. The patients will be recruited during seasonal ARVI morbidity. Collection of history, thermometry, objective examination, laboratory tests, recording concomitant therapy will be made after parent/adoptive parent signing information sheet and informed consent form for the child participation in the clinical study, for children ≥14 years old after signing patient information sheet and informed consent form for children ≥14 years old to participate in the clinical study. The severity of ARVI symptoms will be evaluated with a 4-point scale. The nasopharyngeal swabs for PCR diagnosis and verification of respiratory viruses will be performed prior to therapy to confirm the viral etiology of ARVI. To rule out the infection caused by the new coronavirus COVID-19 (Coronavirus disease 2019), a rapid test for SARS-CoV-2 antigen will be made. In case of a positive SARS-CoV-2 test, the physician will act in accordance with the current version of the RF MoH Temporary methodological recommendations Prevention, diagnosis, and therapy of new coronavirus infection (COVID-19). 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: patients of group 1 will take Raphamin according to the dosage regimen for 5 days; patients of group 2 will take Placebo using Raphamin 5-day regimen. The study will use an electronic patient diary (EPD) for recording morning and evening axillary body temperature (using a classic mercury-free thermometer) and disease symptoms (Symptom Severity Score). Besides, antipyretic dosing (if applicable) and any deterioration in a patient's condition (if applicable, for safety evaluation/AE documentation) will also be recorded in a patient diary. The investigator will provide instructions on filling the diary. At Visit 1 the parent/adoptive parent together with an investigator will record ARVI symptom severity and body temperature in the diary. Patients will be observed for 14 days (screening, randomization - up to 1 day, treatment period - 5 days, follow-up - up to 2 days; deferred phone visit - day 14). During the treatment and follow-up period the patients/physicians will make 3 visits and the fourth phone visit will be scheduled additionally: 1) visits by physician/patient - on Days 1, 5, and 7 (Visits 1, 2, and 3) - in a study center or at home; 2) phone visit (Visit 4) - on Day 14. At Visits 2 and 3, the investigator will perform an objective examination, document changes in the symptoms and concomitant medications, and check patient diaries. At Visit 3 laboratory tests will be performed and compliance will be checked. Phone visit will be performed to interview parents/adoptive parents about the patient's condition, presence/absence of secondary bacterial/viral complications, and use of antibiotics. During the study, symptomatic therapy and therapy for their co-morbidities are allowed with the exception of the drugs indicated in the section Prohibited Concomitant Treatment.

Interventions

Oral administration - not with food. Keep the tablet in the mouth until it is completely dissolved. On the 1st day of treatment, 8 tablets are taken according to the following scheme: 1 tablet every 30 minutes in the first 2 hours (a total of 5 tablets in 2 hours), then during the same day, take another 1 tablet 3 times at regular intervals. On the 2nd day and then take 1 tablet 3 times a day. The duration of treatment is 5 days.

DRUGPlacebo

MeasureTime frameDescription
Time to Resolution of Acute Respiratory Viral Infection (ARVI) Symptoms (ARVI, Confirmed by Polymerase Chain Reaction (PCR)).14 days of observationOutcome Measure is evaluated on the basis of ARVI, confirmed by Polymerase chain reaction (PCR), i.e virus detection. ARVI's resolution criteria: temperature ≤37.3°С + total symptom score (TSS) ≤2. Axillar temperature, 6 flu-like nonspecific symptoms (headache, chills, sweating, weakness, muscle pain, drowsiness) and 7 nasal/throat/chest symptoms (runny nose, nasal congestion, sneezing, hoarseness, sore throat, cough, pain/heaviness in chest) were registered for TSS according to the 4-point scale for each of them (0 = no symptom; 1 = mild symptom; 2 = moderate symptom; 3 = severe symptom). To calculate TSS absolute axillar temperature (in degrees Celsius) was converted to relative units (or points) using the following scale: ≤37.3 С=0 points; 37.4-38.0 С=1 point; 38.1-39.0 С=2 points; ≥39.1 С=3 points. So the range of TSS was from 0 to 42. The TSS higher score is the worse outcome.

Dosing Frequency of Antipyretics.3 days of therapyOutcome Measure is based on the rates of antipyretic use per patient during days 1 to 3 of therapy according to the electronic patient diary.
Percentage of Patients Reporting Worsening of Illness.Day 4 through day 14 of the treatment and observation periodOutcome Measure is based on the rates of Complications that require the use of antibiotics or hospitalization.
Severity of ARVI (Clinically Diagnosed and/or PCR-confirmed).Day1 through Day6 of the treatment and observationThe outcome measure is based on the area under the curve (AUC) for the TSS (Total symptoms score). TSS is calculated as a sum of scores for 14 different symptoms. 13 of them are different ARVI manifestations, each of them is evaluated on a scale: 0 (none), 1 (mild), 2 (moderate), 3 (severe). 14th symptom is body temperature (temp) which is converted to its score using following rules: if temp \<= 37.3 then score = 0 (none) if 37.3 \< temp \<= 38.0 then score = 1 (mild) if 38.0 \< temp \<= 39.0 then score = 2 (moderate) if 39.0 \< temp then score = 3 (severe) So it is 14 symptoms and the score for each of them varies between 0 and 3. Minimum TSS is 0, maximum is 42 (higher TSS score is worse). AUC is calculated for all timepoints available for patient.
Changes in Vital Signs: Pulse Rate/Heart Rate in Beats Per Minute (Bpm).Day 1 through day 7 of the treatment and observation period.The outcome measure is based on the medical records. The patient's heart rate (heart rate) is measured by the physician in every visit (on days 1, 5, and 7).

Outcome Measure is based on the Percentage of Patients With Resolution of ARVI, confirmed by Polymerase chain reaction (PCR), i.e virus detection. ARVI's resolution criteria: temperature ≤37.3°С + total symptom score (TSS) ≤2. Axillar temperature, 6 flu-like nonspecific symptoms (headache, chills, sweating, weakness, muscle pain, drowsiness) and 7 nasal/throat/chest symptoms (runny nose, nasal congestion, sneezing, hoarseness, sore throat, cough, pain/heaviness in chest) were registered for TSS according to the 4-point scale for each of them (0 = no symptom; 1 = mild symptom; 2 = moderate symptom; 3 = severe symptom). To calculate TSS absolute axillar temperature (in degrees Celsius) was converted to relative units (or points) using the following scale: ≤37.3 С=0 points; 37.4-38.0 С=1 point; 38.1-39.0 С=2 points; ≥39.1 С=3 points. So the range of TSS was from 0 to 42. The TSS higher score is the worse outcome.

Time frame: 14 days of observation

Secondary

Severity of ARVI (Clinically Diagnosed and/or PCR-confirmed).

The outcome measure is based on the area under the curve (AUC) for the TSS (Total symptoms score). TSS is calculated as a sum of scores for 14 different symptoms. 13 of them are different ARVI manifestations, each of them is evaluated on a scale: 0 (none), 1 (mild), 2 (moderate), 3 (severe). 14th symptom is body temperature (temp) which is converted to its score using following rules: if temp \<= 37.3 then score = 0 (none) if 37.3 \< temp \<= 38.0 then score = 1 (mild) if 38.0 \< temp \<= 39.0 then score = 2 (moderate) if 39.0 \< temp then score = 3 (severe) So it is 14 symptoms and the score for each of them varies between 0 and 3. Minimum TSS is 0, maximum is 42 (higher TSS score is worse). AUC is calculated for all timepoints available for patient.

Time frame: Day1 through Day6 of the treatment and observation

Population: Two subpopulations were analysed:~1. Patients with clinically diagnosed and/or PCR-confirmed ARVI.~2. Patients with PCR-confirmed ARVI strictly.
