Clinical Trial of Efficacy and Safety of ММН-407 in Acute Respiratory Viral Infection

Viral Respiratory Infection Clinical Trial

Official title: Multicenter Double-blind Placebo-controlled Parallel Group Randomized Clinical Trial of Efficacy and Safety of MMH-407 in the Treatment of Acute Respiratory Viral Infection

Status Completed

Clinical Trial Summary

To evaluate the efficacy and safety of ММН-407 in treatment of acute respiratory viral infection (ARVI).

Clinical Trial Description

Design: multicenter, double blind, placebo-controlled, parallel group randomized clinical trial.

The study will enroll outpatients of either gender aged 18-70 years old with clinical manifestations of ARVI within the first day after the onset of the disease during seasonal ARVI morbidity.

After signing patient information sheet and informed consent form, medical history, thermometry, objective examination, laboratory tests and concomitant medication will be performed. Severity of ARVI symptoms is evaluated with 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.

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 will take MMH-407 according to the dosage regimen for 5 days; the 2nd group will take Placebo according to MMH-407 dosage regimen for 5 days.

The study will use electronic patient diary for recording morning and evening axillary body temperature (measured using a mercury-free Geratherm Classic thermometer) and disease symptoms (Symptom Severity Score). Besides, antipyretic dosing (if applicable) and any aggravation 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 patient together with a doctor will record ARVI symptom severity and body temperature in the diary.

Patient will be observed for 14 days (screening, randomization - Day 1, treatment period - 5 days, follow-up - up to 2 days; deferred "phone visit" - Day 14).

During the treatment and follow-up period the patients or investigators 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 to check patient diaries. At Visit 3 compliance will be evaluated and laboratory tests will be performed. "Phone visit" is carried out to interview the patient about his/her 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". ;
