5. Study Description

Brief Summary
RACONA is a prospective trial that will test the hypothesis that nafamostat can lower lung function deterioration and need for intensive care admission in COVID-19 patients. Design: Adult hospitalized COVID-19 patients will be randomized in a prospective double-blind randomized placebo-controlled study to test the clinical efficacy of nafamostat mesylate (administered intravenously) on top of best standard of care. Primary outcome measures: the time-to-clinical improvement, defined as the time from randomization to an improvement of two points (from the status at randomization) on a seven category ordinal scale or live discharge from the hospital, whichever comes first.
Detailed Description
Purpose: SARS-Cov-2 enters the lung cells by binding to ACE-2 and activating the protease TMPRSS2, which, therefore, can be a target for antiviral treatment. Accordingly, TMPRSS2 inhibitors prevent SARS-CoV cell entry in vitro. The most potent such inhibitors, nafamostat is being used as anticoagulant and anti-pancreatitis agent, and is approved for the treatment of cystic fibrosis as its mucolytic action can prevent lung function deterioration by owering airways infections. RACONA study will test the hypothesize that nafamostat is useful in COVID-19 lung involvement because COVID-19 entails activation of the coagulation cascade, pulmonary embolism, and bacterial superinfections.
