Inclusion criteria

Key Inclusion Criteria: 1. Subjects who have been confirmed to be COVID-19 corresponding to mild cases of severity categorization classified by FDA through polymerase chain reaction (PCR) test or virus gene test (sequencing) and who can be available to be administered within seven days from the date of manifestation. 2. Subjects who are or will be inpatient. Key

Exclusion criteria

1. Patients with symptoms of moderate or higher in the severity classification presented by FDA have evidence of lower respiratory tract infection in their imaging findings or need supplemental oxygen therapy or mechanical respiration (ie, non-invasive ventilation, invasive mechanical ventilation, extracorporeal membrane oxygenation, etc) 2. Subjects with infectious diseases such as bacteremia or severe pneumonia requiring active treatment within four weeks prior to the IP administration
