16. Patient has been diagnosed with COVID-19 (Coronavirus Disease of 2019) within 4 weeks of Visit 1/Screening.
17. Patient is unable to communicate or cooperate with the investigator due to language problems, poor mental development, or impaired cerebral function.
18. Patient has previously been treated with the IP.
19. Patient has a history of sensitivity to any of the ingredients in the IP.
