Study to Assess Efficacy and Safety of XC221 200 mg in the Treatment of Influenza or Other ARVI

PHARMENTERPRISES LLC120 enrolled

Overview

The innovative drug XC221 is planned for use in treatment of acute respiratory viral infections in a double-blind, randomized, placebo-controlled, comparative multicenter study assessing the safety, tolerability and efficacy of XC221 at a dose of 200 mg per day in patients with uncomplicated influenza or other acute respiratory viral infections during the 3-days treatment.

A double-blind, randomized, placebo-controlled, comparative multicenter study in two groups. A total of 120 patients with uncomplicated influenza or other acute respiratory viral infections are planned to be randomized. Patients will be randomized into 2 groups: 60 patients in the treatment group 200 mg XC221 and 60 patients in the placebo group. The purpose of the clinical trial is to assess the safety, tolerability and efficacy of the drug XC21 in treatment of influenza or other acute respiratory viral infections. The primary objective is to demonstrate the difference between the groups in the time of the onset of sustained improvement in clinical symptoms according to the Modified Jackson Scale. The study will consist of the following periods: screening (duration not more than 36 hours from the moment of the first symptoms of the disease), treatment period (3 days), follow-up period (11 ± 1 days after completion of treatment with the study drug/placebo). The duration of participation in the study for each patient is no more than 16 days and 12 hours.

Outcomes

Primary Outcomes

Time to sustained improvement in clinical symptoms according to the Modified Jackson Scale for measuring respiratory symptoms.

The time before the onset of sustained improvement in clinical symptoms according to the Modified Jackson Scale (no more than 1 point for each symptom), measured in hours from the moment of the first dose of the drug. Modified Jackson Scale measures individuals' subjective ratings the severity of 12 respiratory symptoms. Ranges for each symptom: 0 points (no symptoms) - 3 points (the most severe). Total score (ranges from 0 to 32 points) is a sum of the point for each symptom.

Time frame: From the moment of the first dose up to Day 14

Secondary Outcomes

The time before the onset of persistent improvement in clinical symptoms according to the Modified Jackson Scale for measuring respiratory symptoms (0 points).

The time of the first assessment of 3 consecutive ratings on the Modified Jackson Scale, in which all the clinical symptoms were 0 points. Modified Jackson Scale measures individuals' subjective ratings the severity of 12 respiratory symptoms. Ranges for each symptom: 0 points (no symptoms) - 3 points (the most severe). Total score (ranges from 0 to 32 points) is a sum of the point for each symptom.

Time frame: From the moment of the first dose up to Day 14

The time before the onset of persistent improvement in clinical symptoms according to the Modified Jackson Scale for measuring respiratory symptoms.

Total score of no more than 3 points, when there is no more than 1 point for each symptom, measured in hours from the moment of taking the first dose of the drug. Modified Jackson Scale measures individuals' subjective ratings the severity of 12 respiratory symptoms. Ranges for each symptom: 0 points (no symptoms) - 3 points (the most severe). Total score (ranges from 0 to 32 points) is a sum of the point for each symptom.

Time frame: From the moment of the first dose up to Day 14

Time to normalization of body temperature.

Measured in hours. Normalization means the establishment of body temperature below 37° C without a rise above these values in the subsequent observation period.
