Camostat (Foipan®)

In addition to binding to the ACE2 receptor, priming or cleavage of the spike protein is also necessary for viral entry, enabling the fusion of viral and cellular membranes. SARS-CoV-2 uses the cellular protease transmembrane protease serine 2 (TMPRSS2). Compounds inhibiting this protease may therefore inhibit viral entry (Kawase 2012). The TMPRSS2 inhibitor camostat, approved in Japan for the treatment of chronic pancreatitis (trade name Foipan®), may block the cellular entry of the SARS-CoV-2 virus (Hoffmann 2020). Clinical data are pending. At least five trials are ongoing, mostly in mild-to-moderate disease.
