UnlabelledMost subjects with the COVID-19 experience mild to moderate symptoms, but approximately 10% of cases suffer from severe course of disease. IL-6 inhibitors are actively used to neutralize and prevent the cytokine storm. Olokizumab is a humanized monoclonal antibody belonging to the G4/Kappa immunoglobulin isotype that selectively binds to human IL-6 and effectively neutralizes it.AimTo evaluate the efficacy and safety of Artlegia (olokizumab) for the treatment of subjects with a disease caused by the SARS-COV-2 virus in a real-world clinical setting.Materials And MethodsThe analysis included data of 610 subjects aged 55.0812.68 years who received olokizumab at a single dose of 160 mg/mL 0.4 mL subcutaneously as a preemptive anti-inflammatory therapy. The comparison group included 511 subjects aged 55.2311.23 years who received standard therapy without IL-6 inhibitors. Control Endpoints: 1. Positive clinical changes on Day 7. 2. Changes in the CRP levels on Days 1, 2, and 7. 3. Duration of oxygen therapy. 4. Number of days in hospital. 5. Number of adverse events. 6. Disease outcome.ResultsIf a cytokine storm occurs, immune regulatory events will trigger the development of either a protective immune response or an exacerbated inflammatory response. The use of preemptive anti-inflammatory therapy has both a short-term and, most importantly, a long-term effect on the T and B parts of the immune process. These aspects definitely require further research and observation.ConclusionThe use of olokizumab to treat the new COVID-19 coronavirus disease has demonstrated a positive effect on clinical and laboratory parameters. Primarily, it affects the severity of clinical parameters by improving the general condition already on the first day of observation, and decreasing body temperature to normal values. The changes in the C-reactive protein levels show a significant effect of the IL-6 inhibitor on the systemic inflammatory response.
