About

COVID-19 is causing a serious viral pandemic in terms of health and social impact. To date, no treatment has yet demonstrated Strong efficacy in treating the infectious disease (COVID-19). Pulmonary administration of Interferon (IFN) type I is a therapeutic strategy with high potential,due to higher local concentrations and minimal adverse effects. Type I interferons (including IFN-α and IFN-β) are antiviral defence cytokines and also have the potential to negatively modulate IFN Type II and IL-6 dependent cytokine storm, the latter being induced in the late forms of COVID-19. In vitro, IFN-β were more effective on COVID-19 than IFN-α. In existing preliminary studies, only patients receiving IFN type I modulators have a decrease in viral carriage and a rapid reversal. The purpose of this project is to assess in hospitalized patients with oxygen for COVID 19, the clinical efficacy on oxygen requirements of the addition of inhaled Interferon type I compared to the control arm .
