This double blind, randomized study is aiming to evaluate the efficacy of three doses (1gr/day) of methylpredisolone added to standard therapy in patients, with documented COVID-19 pneumonia, requiring hospitalization but not mechanical ventilation.

Patients recently hospitalized for the treatment of documented COVID-19 pneumonia who do not require invasive ventilation will be randomized (1:1) to receive current standard treatment, which may include desamethasone and oxygen, with methylprenisolone 1gr daily iv for 3 consecutive days or standard treatment alone.

Efficacy measures will be time to recovery (discharge from hospital), invasive ventilation prevention and survival.

Patients safety will be evaluated throughout the all study period.
