简要总结
In-vitro studies revealed that nafamostat mesylate has antiviral activity against Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and anti-inflammatory and anti-coagulation effect. However, there is no clinical studies on the efficacy of nafamostat in patients with COVID-19.
This study is conducted to evaluate the clinical efficacy of nafamostate mesylate in adult patients hospitalized with COVID-19 pneumonia.
详细描述
-
The COVID-19 epidemic expanded to the whole world since it started from the Wuhan area in China in Dec. 2019. The Republic of Korea experiences a sharp increase in the patient since 24th Feb. 2020. An analysis of more than 70,000 patients in China, about 15% of them cause severe pneumonia, 5% require treatment in the intensive care unit, half of them die of the disease.
-
There is no proven therapeutics for COVID-19 patients yet. Currently, the treatment with Kaletra, Hydroxychloroquine, etc. did not show apparent effect, and there are no other drugs that can apply to patients who get worse even with those drugs or severe.
-
There are research reports that defective innate immunity and accelerated activation of the complement cascade, caused by the SARS-CoV-2, induce rapidly progressing pneumonitis.
-
Action mechanism of Nafamostat mesilate A. Show anti-viral effect by an inhibition serine protease, which is required for the host membrane fusion of viral envelop protein. In vitro experiments showed that the drug is effective in MERS-CoV, Influenza virus, and SARS-CoV-2.
B. Show anti-inflammatory effect by inhibition of the complement pathway, and inhibition of cytokine production.
This study is conducted to evaluate the clinical efficacy of nafamostate mesylate in adult patients hospitalized with COVID-19 pneumonia.

研究组 & 干预措施
Conventional therapy + Nafamostat mesylate
-
The conventional therapy comprised, as necessary, Lopinavir/ritonavir, Hydroxychlorquine, supplemental oxygen, Non-invasive and invasive ventilation, antibiotic agents, renal-replacement therapy (e.g.: CRRT, HD), extracorporeal membrane oxygenation (ECMO).
-
Nafamostat mesylate injection day), taking into account the severity and underlying disease of the clinical trial patient.
-
Method of administration: Nafamostat injection is mixed with 1,000 ml of 5% DW infusion, followed by continuous infusion over 24 hours.
-
Duration of administration: The researcher administers for 10-14 days considering the severity and underlying disease of the clinical trial patient.
干预措施: Nafamostat Mesylate (Drug)
