Observational Open Study of Polyoxidonium in Hospitalized Patients With COVID-19

Completed

• Conditions: Infections, Coronavirus
• Interventions: Drug: Polyoxidonium

• Registration Number: NCT04542226
• Lead Sponsor: NPO Petrovax

Brief Summary

The study is designed as an open observational non-comparative study of Polyoxidonium®, lyophilizate for solution for injections and topical application, 12 mg in hospitalized patients with coronavirus disease (COVID-19).

Detailed Description

The study was planned as an observation of Polyoxidonium® administered in addition to Russian Ministry of Healthcare (MoH) guidance for standard COVID-19 treatment. Regimens have no limitations to the use of concomitant therapy. The aim of the study is to observe the safety and efficacy of Polyoxidonium®, lyophilizate for solution for injections, 12 mg in addition to complex treatment of hospitalized patients with COVID-19.

5. Male and female patients from 18 years of age.

6. Confirmed diagnosis of coronavirus disease (COVID-19): laboratory-confirmed Severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2) infection as determined by polymerase chain reaction (PCR), or other commercial or public health assay in any specimen prior to inclusion.

Exclusion Criteria

Group	Intervention	Description
Adult patients hospitalized with COVID-19	Polyoxidonium	Patients eligible for enrollment into the study

Primary Outcome Measures

Name	Time	Method
Clinical Status of the Patient (According to 7-point Ordinal Scale)	Day 1 (Baseline), Day 15	Subject clinical status using the 7-point Ordinal Scale, specified as the primary endpoint in the WHO Master Protocol on day 15 as compared to baseline; (1 - Not hospitalized, no limitations on activities; 2 - Not hospitalized, limitation on activities; 3 - Hospitalized, not requiring supplemental oxygen; 4 - Hospitalized, requiring supplemental oxygen; 5 - Hospitalized, on non-invasive ventilation or high flow oxygen devices; 6 - Hospitalized, on invasive mechanical ventilation or extracorporeal membrane oxygenation; 7 - Death).

Secondary Outcome Measures

Name	Time	Method
Time to Improvement in Clinical Status of the Patient (According to Ordinal Scale) by 1 Point for Each OS Score	Days 1 - 29.	Ordinal scale (OS) score status, time to improvement by 1 point for each OS score.; Subject clinical status using the 7-point Ordinal Scale: 1. - Not hospitalized, no limitations on activities; 2. - Not hospitalized, limitation on activities; 3. - Hospitalized, not requiring supplemental oxygen; 4. - Hospitalized, requiring supplemental oxygen; 5. - Hospitalized, on non-invasive ventilation or high flow oxygen devices; 6. - Hospitalized, on invasive mechanical ventilation or extracorporeal membrane oxygenation; 7. - Death.
Clinical Status of the Patient (According to National Early Warning Score (NEWS Scale))	Days 1 - 29.	NEWS scale score status, time to a discharge from a hospital or to a NEWS of ≤ 2 and maintained for 24 hours, whichever occurs first.; NEWS score is based on 7 clinical parameters: respiration rate, oxygen saturation, supplemental oxygen, systolic blood pressure, pulse rate, level of consciousness, temperature. A score of 0, 1, 2, 3 is allocated to each parameter except supplemental oxygen (a score 0 or 1 is allocated) and level of consciousness (a score 0 or 3 is allocated). A higher score means the parameter is further from the normal range. All scores were summed to get an aggregate score. Aggregate score ranges from 0 to 19, with higher scores meaning higher risk.; Low risk - aggregate score, 1-4 Low to medium risk - score 3 in any single parameter, Medium risk - aggregate score 5-6, High risk - aggregate score 7-19.
Number of Patients Requiring Supplementary Oxygen	Days intervals 1 (baseline), 3, 5, 8, 11, 15, 29.	Number of patients requiring supplementary oxygen on Days 3, 5, 8, 11, 15, 29
Hospitalisation Duration	Days 1 - 29	Duration of hospitalisation
Mortality	Days 1 - 29.	Number of participants who were dead or alive (Days 1 - 29)
The Number of Participants With Serious Adverse Events	Days 1 - 29.	The number of participants with serious adverse events (SAE)
The Number of Participants With Adverse Events	Days 1 - 29.	The number of participants with adverse events (AE)
Number of Participants With Discontinuation of Drug Administration	Days 1 - 17.	Number of participants with Permanent or temporary discontinuation of infusions or injections due to adverse events
