Key Inclusion Criteria:

  1. Over 19 years of age
  2. COVID-19 confirmed by a real-time RT-PCR tests, and hospitalized
  3. Patients who experienced first symptom related to COVID-19 within 7days prior to enrollment and confirmed 2 or more relative symptoms at the time of randomization.
  4. Patients with peripheral capillary oxygen saturation(SpO2) greater than 94% at the time of screening, who do not need supplemental oxygen therapy.
