Treatment effect of nafamostat mesylate in patients with COVID-19 pneumonia: study protocol for a randomized controlled trial
Abstract
Background This study is designed to evaluate the main hypothesis that nafamostat mesilate with standard therapy improves the severity and mortality rate in patients with COVID-19 pneumonia. Methods We conduct a randomized, open type, multi-institute/center, 2-group clinical trial with COVID-19 pneumonia patients in Korea. Eighty four patients with COVID-19 pneumonia are randomly assigned to intervention group or control group. Patients in intervention group receive the standard therapy with a dose of 0.1 to 0.2 mg/kg/h (2.4 to 4.8 mg/kg/day) of nafamostat mesilate. Patients in control group receive the standard therapy such as lopinavir/ritonavir, hydroxychloroquine, oxygen therapy, non-invasive and invasive ventilator, antibiotic therapy, renal-replacement therapy, and extracorporeal membrane oxygenation (ECMO). The primary outcome is proportion of patients with clinical improvement as defined by live discharge from hospital or a decline of 2 categories on the seven-category ordinal scale of clinical status, as well as secondary outcome comprised change in National Early Warning Score, duration of hospitalization, incidence of new-non-invasive ventilation or high flow oxygen use or ventilator, mortality at day 28, viral load change, and adverse events. Discussion Our study contributes to the establishment of therapeutic strategy in COVID-19 pneumonia by evaluating the therapeutic effect and safety of nafamostat mesilate.

How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 19 participants or records.
