Key Inclusion Criteria:

• Hospitalized patient with clinically diagnosis of SARS-CoV-2 virus infection per World Health Organization criteria including positive nucleic acid test of any specimen (e.g., respiratory, blood, or other bodily fluid) within 2 weeks prior to screening.{Other confirmatory test results will be accepted upon approval from Sponsor/CRO Medical Monitor prior to enrolment}.
• Symptoms suggestive of moderate systemic illness with COVID-19, which could include any of the following symptoms: fever, cough, sore throat, malaise, headache, muscle pain, gastrointestinal symptoms, or shortness of breath at rest, or respiratory distress.
• Clinical signs indicative of moderate systemic COVID-19 illness (with high risk of developing severe ARDS/septic shock) with an aggregate of NEWS-2 score of 4-6 or 3 in one single parameter.

Key Exclusion Criteria:

Patients who meet any of the following criteria will be disqualified from entering the study:

• Patients who require endotracheal intubation and mechanical ventilation, oxygen delivered by high-flow nasal cannula (heated, humidified, oxygen delivered via reinforced nasal cannula at flow rates >20 L/min with fraction of delivered oxygen ≥ 0.5), non-invasive positive pressure ventilation, ECMO, or clinical diagnosis of respiratory failure.
• Presence of any of the following abnormal laboratory values at screening: aspartate aminotransferase (AST) or alanine aminotransferase (ALT) >5 x upper limit of normal (ULN), platelets <50,000/µL.
• Treatment with anti-IL 6, anti-IL-6R antagonists, or with Janus kinase inhibitors in the past 30 days or plans to receive during the study period.
• Current treatment with conventional synthetic disease-modifying antirheumatic drugs (DMARDs)/immunosuppressive agents.
• Use of chronic oral corticosteroids for a non-COVID-19-related condition in a dose higher than prednisone 10 mg or equivalent per day.
• History of, or current autoimmune or inflammatory systemic or localized disease(s) other than rheumatoid arthritis.
