About

Pneumonia caused by coronavirus infection COVID-19 is characterized by a combination of several dangerous factors that consistently worsen the patient's condition: viral lung damage early in the disease; a sharp increase in inflammation on the background of an unbalanced immune response ("cytokine storm"); joining a bacterial infection.

The condition of patients deteriorates significantly mostly at cytokine storm development. The damaging of a large volume of lung tissue leads to develops of respiratory failure, respiratory distress syndrome, or shock. Ventilatory support becomes ineffective and patients die.

There are reports of the effectiveness of Human Normal Immunoglobulin for Intravenous Administration (IVIG) high doses when used as part of complex therapy in patients with pneumonia caused by coronavirus COVID-19. In particular, IVIG has a positive effect on survival rates, overall disease course, duration of stay in the intensive care unit, and ventilatory support duration.

The probable mechanism of action of high-dose IVIG therapy is considered to be a regulatory effect on the immune system. Similar is the known and confirmed effectiveness of IVIG for autoimmune diseases (Kavasaky disease, Guillain Barre syndrome, Chronic inflammatory demyelinating polyradiculoneuropathy, Multifocal motor neuropathy).

This trial to assesses the Efficacy of IVIG (medication trade name - Bioven, manufactured by Biopharma Plasma LLC) in the High Immunomodulatory Dose in Complex Treatment of Severe Pneumonia Caused by COVID-19 / SARS-CoV-2

Full description

The screening stage:

The patient or his legal representative must sign an informed consent. After signing the informed consent, the screening tests&procedures are performed and the compliance with the inclusion / non-inclusion criteria is assessed.

For patients who have been screened and meet the inclusion criteria and do not fall under the exclusion criteria, a blinded randomization procedure is provided.

Randomization is performed by the IVRS method, according to the blinded-block patient's randomization table.

The clinical stage of the trial:

Begins after patient randomization. At the clinical stage, among other things, provides:

Determination of the individual dose of the study drug (in the study group)
Administration of the drug (in the study group)
Registration of adverse events
registration of information about taking antiviral drugs for the treatment of COVID-19;
registration of information on symptomatic therapy and administration of drugs for the treatment of comorbidities;
measurement of vital signs (blood pressure, heart rate, respiratory rate, body temperature);
Determination of SPO2 level
Determining the need for ventilation
Determining the need for intensive care
Assessment of compliance with the exclusion criteria

Patients in the Control Group will receive therapy recommended by the COVID-19 coronavirus infection treatment protocol, depending on the severity of their condition according to the prescribing list, which will not include immunoglobulin preparations.

Patients of the Study Group (IVIG) receive high-dose therapy with the study drug (Bioven, 10% solution for infusions produced by Biopharma Plasma LLC, Ukraine). The dose is calculated by body weight. Patients will also receive therapy recommended by the COVID-19 coronavirus infection treatment protocol, depending on the severity of their condition according to the prescribing list.

Bioven administered intravenously, at an initial rate of 0.5 - 1.0 ml/kg body weight/hour for 30 minutes. In the absence of any undesirable side effects, the rate of administration can be gradually increased (recommended increase by 0.5 - 1.5 ml/kg body weight/hour every 10 minutes). According to results previously accomplished clinical studies, the maximum rate of Bioven administration is up to 8.5 ml/kg body weight/hour.

Observation and completion stage:

Begins and continues from the last administration of the study drug until the discharge of the patient from the hospital, but not less than 28 days from the confirmation of the diagnosis of pneumonia caused by coronavirus infection COVID-19.

The following procedures are provided at the stage:

registration of information about taking antiviral drugs for the treatment of COVID-19;
registration of information on symptomatic therapy and administration of drugs for the treatment of comorbidities;
measurement of vital signs (blood pressure, heart rate, respiratory rate, body temperature);
determination of SPO2 level
registration of the results of the examination of the lungs by computed tomography (or radiography)
taking biomaterials for laboratory research:
general blood test (erythrocytes, hemoglobin, expanded leukocyte formula, platelets, etc.);
general analysis of urine;
biochemical analysis of blood;
state of the coagulation system
determination of inflammatory factors in the dynamics (CRP, ferritin, procalcitonin; TNF-α), IL-1-beta, IL-6, complement component C3 (C3), circulating immune complexes (CIC), etc.),
determination of IgG subclasses (G1, G2, G3, G4,);
Determining the need for ventilation
Determining the need for intensive care
Adverse reactions registration
Assessment of compliance with the exclusion criteria

The patient's condition is assessed daily till discharge; and by schedule after discharge (if it happen earlier), during 28 days period after diagnosis of severe pneumonia caused by coronavirus infection COVID-19 In case of death of the patient - the date and cause of death are fixed. The results of the study are evaluated by endpoints.

Inclusion criteria

Men and women 18 years of age and older;
COVID-19 documentary confirmed by PCR lab test;
severe pneumonia caused by COVID-19 according to the criteria below:
- - fever or suspicion of respiratory infection;
- - the number of respiratory movements 30 per 1 min and above;
- - severe respiratory failure or SpO2 <90% with spontaneous breathing indoors;
- - the presence of foci of inflammation in the lungs according to the results of computed tomography, which is documented.
- or if any of the conditions listed below have developed on the background of previously diagnosed coronavirus pneumonia:
  - - severe respiratory failure required mechanical ventilation (ALV);
  - - acute respiratory distress syndrome according to WHO diagnostic criteria (development within one week after the manifestation of disease clinical symptoms or emergence of new ones or deterioration of respiratory syndromes. Chest visualization (lung X-ray, CT or ultrasound); bilateral opacities not fully explaining the gravity of condition or lung collapse or nodules);
  - - sepsis according to WHO diagnostic criteria (life-threatening organ dysfunction caused by disturbance of host reaction to suspected or proven infection. The features of organ dysfunction include the following: mental change, labored or shallow breathing, low oxygenation, oliguria or anuria, rapid heart palpitation, weak pulse, cold extremities or low blood pressure, skin blotching or lab-proven coagulopathy, thrombocytopenia, acidosis, high level of lactic acid or hyperbilirubinemia);
