Study to Assess Efficacy and Safety of XC221 in the Treatment of Influenza and Other Acute Respiratory Viral Infections

14 de octubre de 2019 actualizado por: PHARMENTERPRISES LLC

Multicenter Double-blinded Placebo-Controlled Parallel-Group Randomized Clinical Trial of Efficacy, Safety and Choice of an Optimum Dose of XC221 in the Treatment of Influenza and Other Acute Respiratory Viral Infections in Adults

A multicenter double-blinded, randomized, placebo-controlled, parallel-group comparative Phase II clinical study to assess safety, tolerability, efficacy and optimal dose of XC221 vs. placebo in patients with uncomplicated influenza or other ARVI during a 3-day treatment.

The primary objective of the study is to demonstrate the difference in time before the onset of a sustained improvement in clinical symptoms according to the Modified Jackson Scale for ARVI and to determine the optimal dose of XC221 in the treatment of influenza and other ARVI.

Descripción detallada

11 Russian centers were planned for participation in this study. The study consists of three periods: screening, treatment and follow-up.

All eligible patients will be randomized into 3 groups (groups A, B and C) in a 1:1:1 ratio:

Group A - XC221 100 mg daily (40 patients); Group B - XC221 200 mg daily (40 patients); Group C - Placebo (40 patients).

During the treatment period (3 days), patients will receive XC221 / placebo daily on a background of standard symptomatic therapy. The follow-up period lasts for 11 days.

Time to Sustained Improvement in Clinical Symptoms Based on Modified Jackson Scale for ARVI
Periodo de tiempo: From the time of randomization up to Day 14

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.
From the time of randomization up to Day 14

Periodo de tiempo: From the time of randomization assessed up to Day 14
Time to body temperature normalization since treatment initiation, measured in hours (normalization is regarded as setting of body temperature below 37°C without elevation above these values)
From the time of randomization assessed up to Day 14
Percentage of Patients With Complications
Periodo de tiempo: From the time of randomization up to Day 14
The percentage of patients with complications of influenza/acute viral URI
From the time of randomization up to Day 14
