A Study to Evaluate the Safety, Tolerability and Efficacy of XC221 in Patients With Uncomplicated Influenza or Other Acute Viral Upper Respiratory Infections
A Multicenter, Randomized, Double-blind, Placebo-сontrolled Comparative Study to Evaluate the Safety, Tolerability and Efficacy of XC221 Used at 100 mg Daily and at 200 mg Daily in Patients With Uncomplicated Influenza or Other Acute Viral Upper Respiratory Infections
A multicenter, randomized, double-blind, placebo controlled comparative study to evaluate the safety, tolerability and efficacy of XC221 used at 100 mg daily and at 200 mg daily in patients with uncomplicated influenza or other acute viral upper respiratory infections (URIs) for 5 days of treatment.
The primary objective of the study is to evaluate the efficacy of ХС221 at 100 mg and at 200 mg in comparison with placebo regarding its effect on the severity and duration of influenza symptoms and symptoms of other viral URIs (fever and other major signs and symptoms).
The secondary objective of the study is to evaluate the safety of ХС221 at 100 mg and at 200 mg in comparison with placebo in the treatment of influenza ad other viral URIs.

Intervention / Treatment
Detailed Description
Russian centers will participate in this study. This is a double-blind, placebo-control study, and therefore, in order to maintain the study design, subjects will be administered with placebo or the study drug depending on the treatment group they have been randomized into.
The screening visit and all other visits of the study will be on an outpatient basis (including home visits). The study will consist of three periods: screening, randomization and initiation of treatment ( Day 1); treatment period (Day 1-5) and follow-up period (Day 6-20± 1 after completion of treatment with XC221 / Placebo). The duration of participation in the study for each patient will be no more than 21 days.
255 eligible patients will be randomized into three treatment groups (in a 1:1:1 ratio) and receive: study drug (ХС221) at 100 mg daily or at 200 mg daily, or placebo. Regardless other group, all study subjects should receive the standard symptomatic therapy for influenza and other viral URIs, taking into account the latest clinical guidelines (the necessity of symptomatic therapy will be decided by the Investigator).
Group 1: subjects will receive 1 tablet of XC221, 100 mg tablets orally in the morning (between 7:00 and 11:00) and 1 tablet of placebo in the evening (between 19:00 and 23:00) regardless of food intake for 5 days.
Group 2: subjects will receive 1 tablet of XC221, 100 mg tablets orally twice daily in the morning (between 7:00 and 11:00) and in the evening (between 19:00 and 23:00) regardless of food intake for 5 days.
Group 3: subjects will receive 1 tablet of placebo orally twice daily, in the morning (between 7:00 and 11:00) and in the evening (between 19:00 and 23:00) regardless of food intake for 5 days.
