Clinical Trial Summary

This is open-labe randomized multicenter comparative Phase III study conducted in 8 medical facilities. The objective of the study is to assess the efficacy, safety and tolerability of Ambervin for intramuscular and inhaled administration in complex therapy COVID-19 compared with the Standard of care (SOC) in hospitalized patients with moderate COVID-19.

20. Any history data that the investigating physician believes could lead to complication in the interpretation of the study results or create an additional risk to the patient as a result of his/her participation in the study.

21. Patient's unwillingness or inability to comply with procedures of the Study Protocol (in the opinion of physician investigator).
