Brief summary

Pilot clinical trial, with a marketed drug -natural component of human plasma-, not approved for this indication, single-center, exploratory, open, randomized, controlled, to study the efficacy and safety of human Antithrombin in patients with confirmed COVID-19 disease and criteria high risk to develop SARS.

Interventions

DRUGAntithrombin + best available treatment

The subject will be treated with Antithrombin (50 IU/Kg/12h) for 72 hours and the best available treatment for COVID-19.

The subject will be treated with the best available treatment for COVID-19.
