NCT05030324

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Time (in hours) from the first dose of the drug to the resolution of all of the following symptoms/events.

    • fever (the day of fever resolution is the first day on which stable normal body temperature is achieved (\<37.0°C without the use of antipyretics)); All achieved symptoms/events scores maintained for at least 24 h at 0-1 point: * nasal congestion/runny nose; * sore throat; * cough; * muscle aches; * headaches; * fatigue; * chills/sweats. Patients will assess and record the severity of all symptoms on a 4-point scale in the Patient's Diary for 10 days 2 times a day with a 12 ± 2 h interval before the next use of symptomatic agents, where: 0 points - no symptom; 1 point - the minimum severity of the symptom; 2 points - moderate severity of the symptom; 3 points - the maximum severity of the symptom.

    Day 1 - Day 10

Secondary Outcomes (18)

  • Time to decrease in 24-hour body temperature to ≤ 37.0°C without using antipyretics (number of hours from the first dose of the study treatment to a decrease in 24-hour body temperature to ≤ 37.0°C).

    Day 1 - Day 10

  • Time to nasal congestion/runny nose resolution (number of hours from the first dose of the drug to runny nose/congestion resolution, i.e. the time when the subject rates the 24-hour severity of this symptom at 0-1 point)

    Day 1 - Day 10

  • Patient rate with reported nasal congestion/runny nose resolution by day 4 and day 6 from treatment initiation (i.e. patient rate who assessed the 24-hour severity of this symptom at 0-1 point).

    Day 1 - Day 6

  • Time to sore throat resolution (number of hours from the first dose of the drug to sore throat resolution, i.e. the time when the subject rates the 24-hour severity of this symptom at 0-1 point).

    Day 1 - Day 10

  • Patient rate with reported sore throat resolution by day 4 and day 6 from treatment initiation (i.e. patient rate who assessed the 24-hour severity of this symptom at 0-1 point).

    Day 1 - Day 6

  • +13 more secondary outcomes

Study Arms (3)
