Abstrakt: To evaluate the safety and the potential antiviral treatment of inhaled enriched heparin in patients with COVID-19. The specific objectives were to investigate the anticoagulation profile, antiviral and anti-inflammatory effects, and respiratory evolution of inhaled enriched heparin. We conducted a randomized, triple-blind, placebo-controlled Phase I/II clinical trial in hospitalized adults with COVID-19 receiving inhalation of enriched heparin or saline (placebo) every 4 h for 7 days. Among the 27 patients who completed the study, no changes in blood coagulation parameters were observed, indicating the safety of inhaled enriched heparin. The group receiving enriched heparin showed a significant reduction in the need for supplemental oxygen and improvement in respiratory parameters, such as the PaO2/FiO2 ratio. Inhalation of enriched heparin is shown to be safe and has also demonstrated potential therapeutic benefits for patients with COVID-19. These promising results justify the continuation of the study to the next phase, Phase II/III, to further evaluate the therapeutic efficacy of inhaled enriched heparin in the treatment of COVID-19-associated viral pneumonia.
