Brief Summary:

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.

Condition or disease Intervention/treatment Phase
Acute Respiratory Viral Infections Influenza Drug: XC221 100 mg Drug: XC221 200 mg Drug: Placebo Phase 2

Detailed Description:

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.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 120 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Masking Description: Blinding will carried out by using Placebo equivalent to XC221 tablets without active substance and the corresponding labeling of the study drug.
Primary Purpose: Treatment
Official Title: 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
