Abstract
A previous report on 814 patients who were coronavirus disease 2019 (COVID-19) positive provided preliminary therapeutic efficacy evidence with interferon-α2b (IFN-α2b) in Cuba, from March 11 to April 14, 2020. This study re-evaluates the effectiveness of IFN-α2b during the period from March 11 to June 17, 2020. Patients received a combination of oral antivirals (lopinavir/ritonavir and chloroquine) with intramuscular or subcutaneous administration of IFN-α2b. The primary endpoint was the proportion of patients discharged from the hospital; the secondary endpoint was the case fatality rate, and several outcomes related to time variables were also evaluated. From March 11 to June 17, 2,295 patients had been confirmed to be severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) positive in Cuba, 2,165 were treated with Heberon[SUP]?[/SUP] Alpha R, and 130 received the approved protocol without IFN. The proportion of fully recovered patients was higher in the IFN-treated compared with the non-IFN-treated group. Prior IFN treatment decreases the likelihood of intensive care and increases the survival after severe or critical diseases. Benefits of IFN were significantly supported by time variables analyzed. This second report confirmed our preliminary evidence about the therapeutic effectiveness of IFN-α2b in SARS-CoV-2 infection and postulated Heberon Alpha R as the main component within antiviral drugs used in the Cuban protocol COVID-19.
