Brief Summary

A multicenter double-blind, randomized, placebo-controlled, parallel-group comparative Phase II / III clinical study to assess safety, tolerability, efficacy and optimal dose ranging of XC8 vs. placebo in patients with uncomplicated influenza or other ARVI during a 5-day treatment.

The primary objective of the study was to demonstrate the difference in time before the onset of a sustained improvement in clinical symptoms according to the Severity Rating Scale for ARVI, and to determine the optimal dose of XC8 in the treatment of influenza and other ARVI.

Detailed Description

Twenty-three Russian centers were approved for participation in this study. Twenty centers were initiated. Patients were enrolled in 18 centers. The study consisted of two parts: phase II and phase III. Each of the parts included 3 periods: screening, treatment, follow-up.

In the first part of the study (Phase II), all eligible patients were randomized into 4 groups (groups A, B, C, and D) in a 1:1:1:1 ratio:

Group A - XC8 20 mg daily (40 patients); Group B - XC8 100 mg daily (40 patients); Group C - XC8 200 mg daily (40 patients); Group D - placebo (40 patients).

Interim analysis was planned after the end of the first part of the study (Phase II). Based on the results of the interim analysis, the most promising XC8 dose group was selected and the necessary set was calculated to compare this group with the placebo group by the primary endpoint in a pooled set using an adaptive design with type I error control.

In the second part of the study (Phase III), all eligible patients were randomized into 2 groups (groups C and D) in a 1:1 ratio:

Group C - XC8 200 mg daily (80 patients); Group D - placebo (80 Patients).

During the treatment period (5 days), patients received XC8 / placebo daily on a background of standard symptomatic therapy. The follow-up period lasted for 9 days.
