Respiratory frequency ≥30/min. 2. Blood oxygen saturation ≤93% on room air (RA). 3. Partial pressure of arterial oxygen to fraction of inspired oxygen ratio (PaO2/FiO2) \<300. 4. Worsening of lung involvement, defined as an increase in number and/or extension of pulmonary areas of consolidation, need for increased FiO2 to maintain stable O2 saturation, or worsening O2 saturation of \>3% with stable FiO2. Exclusion Criteria: * Baseline elevation of alanine aminotransferase (ALT) or aspartate aminotransferase (AST) levels \> 3-fold the upper limit of the normal range. * Pregnancy.
