Clinical Trial Summary

The purpose of this study is to demonstrate the superiority of Polyoxidonium®, lyophilizate for solution for injections and topical application, 6 mg over placebo in hospitalized patients with coronavirus disease (COVID-19). This is a multicentre prospective, randomized, double-blind, placebo-controlled, parallel-group phase IIb\IIIa clinical trial.

Description:

This is a multicenter prospective, randomized, double-blind, placebo-controlled, parallel-group phase 3 IIb\IIIa trial to evaluate the efficacy of Polyoxidonium®, lyophilizate for solution for injections and topical application, 6 mg over placebo in hospitalized patients with coronavirus disease (COVID-19). A study will last for 29±3 days (maximum) for each participant and will include: screening (days -1...1); treatment period (17 days in total, days 1...17) with the administration of the investigational product Polyoxidonium/placebo (intravenous injections for 3 days, then intramuscular injections for 14 days), assessment of the clinical status, recording of AEs; follow-up period (days 18...29±3).

Haematology and blood chemistry tests will be performed at day -1 and days 1,3, 8 ±1, 17±1.

Assessment of the clinical status according to the 7-point ordinal scale and according to the National Early Warning Score (NEWS) scale will be done every day during hospitalization from day 1 up to and including day 17 and at the follow-up on day 29±3.

The safety and tolerability will be evaluated throughout the study (from signing the Informed Consent Form to the study completion visit).

Primary	Clinical status of the patient (according to 7-point ordinal scale)	The primary efficacy outcome will be defined based on the blinded analysis of data of the first 100 patients in the 1st part of the study. There is uncertainty about the clinical course and potential different trajectories according to baseline disease severity, so the day of the primary endpoint may be modified based on a blinded evaluation of the primary efficacy outcome in various days.

Average change in the ordinal scale from baseline.	Clinical status of the patient and the average change in the ordinal scale from baseline, both on days 3, 5, 8, 11, 29.
Secondary	NEWS	The time to discharge or to a NEWS of = 2 and maintained for 24 hours, whichever occurs first.; Change in NEWS from baseline.	Change in NEWS from baseline on days 3, 5, 8, 11, 15, 29.
Secondary	Oxygenation	Oxygenation free days. Incidence and duration of new oxygen use.	Oxygenation free days in the first 28 days (to day 29). Incidence and duration of new oxygen use during the study.
Secondary	Mechanical Ventilation	Ventilator free days. Incidence and duration of new mechanical ventilation use.	Ventilator free days in the first 28 days (to day 29). Incidence and duration of new mechanical ventilation use during the trial.
