Emricasan (IDN-6556, PF-03491390) is a drug originally invented by Pfizer and licensed for development to Conatus Pharmaceuticals, which acts as a caspase inhibitor and has antiinflammatory effects. It was developed for the treatment of liver disease,^[1] and has been granted fast track designation by the FDA for development after positive results in Phase II clinical trials for non-alcoholic fatty liver disease.^[2]^[3] Emricasan is the first caspase inhibitor developed for clinical use, and this novel mechanism of action has led to interest in research using emricasan for other potential applications such as an anti-cancer or antiviral drug.^[4]^[5]
