Description Either cancer or hepatitis will get what's coming to it from ItherX Pharmaceuticals. The biotechnology drug development firm has focused its efforts on discovering treatments in two areas: oncology and virology. In the field of virology, ItherX Pharmaceuticals is developing compounds to fight the hepatitis C virus (HCV) at the earliest stages of infection by blocking entry of the virus into healthy cells. The company also has research programs for cell-based oncology therapies. ItherX Pharmaceuticals, formerly Immusol, changed its name in 2008.
