Sun Pharmaceutical to Commence COVID-19 Clinical Trials Targeting Generic Nafamostat Mesylate

The Sun Pharmaceutical Industries Ltd announced approval from Indian drug authority known as the Drugs Controller General of India (DCGI) to launch a clinical trial with Nafamostat Mesylate in COVID-19 patients. A drug approved in Japan for improvement of acute symptoms of pancreatitis and treatment of Disseminated Intravascular Coagulation (DIC), a group of preclinical research investigators from the University of Tokyo, Japan and Leibniz Institute for Primate Research in Germany demonstrated that the drug, at low concentrations, suppresses the protein called TMPRSS2 that SARS-CoV-2 uses to enter human lung cells.

Moreover, another research group associated with Institut Pasteur, South Korea published data comparing antiviral efficacy of 24 drugs, and Nafamostat was found to be the most potent of the batch and capable of inhibiting the virus at very low concentrations, consistent with the findings from the Japanese and German preclinical research efforts.

Current Clinical Trials

According to the Sun Pharmaceutical press release, there are presently three clinical trials underway to test Nafamostat in COVID-19 patients. These trials are led by the University of Tokyo Hospital, Japan, Gyeongsang National University Hospital (South Korean), and a collaborative trial by University Hospital, Padova, University of Zurich, Switzerland, and Yokohama City University, Japan (RACONA) study which is disclosed in
