Faldaprevir was an experimental drug for the treatment of hepatitis C (HCV). It was being developed by Boehringer-Ingelheim and reached Phase III clinical trials in 2011.^[1] Boehringer announced in 2014 that it would not pursue approval of the drug any more because of better HCV treatments having become available.^[2]

Mechanism of action

Faldaprevir is a hepatitis C virus protease inhibitor.^{[citation needed]}

Studies

Faldaprevir was tested in combination regimens with pegylated interferon and ribavirin, and in interferon-free regimens with other direct-acting antiviral agents including deleobuvir.^{[citation needed]}

Data from the SOUND-C2 study, presented at the 2012 AASLD Liver Meeting, showed that a triple combination of faldaprevir, deleobuvir, and ribavirin performed well in HCV genotype 1b patients.^[3]
