An Open-label, prospective, randomized, comparative, multiple doses applied in addition to the standard of care treatment of patients with moderate to severe COVID-19 infection

The justification for the use of immunomodulatory therapy is based on the evidence that drugs that are inhibitors of interleukin IL6 may prevent the more severe lung tissue damage caused by cytokine release in patients with more severe COVID19. Several studies have suggested a "cytokine storm" caused by the release of IL-6, IL-1, IL-12 and IL-18 with tumor necrosis factor TNF alpha and other inflammatory mediators. Increased inflammatory response of lung tissue may result in increased gas exchange at the alveolar-capillary level making oxygenation difficult in patients with more severe forms of the disease and the need for mechanical ventilation. In this regard, it is hypothesized that the use of immunomodulatory therapy should have an effect in reducing the lethal outcome, the need for oxygen therapy, and mechanical ventilation.
