A fixed-dose tablet comprising the NS5A inhibitor ombitasvir, the NS3/4A inhibitor paritaprevir and ritonavir (ombitasvir/paritaprevir/ritonavir) (Technivie(®), Viekirax(®)) is available for use, in combination with ribavirin, for the treatment of chronic hepatitis C virus (HCV) genotype 4 infection. High sustained virological response rates at 12 weeks post-treatment (SVR12) were achieved in treatment-naive or -experienced patients with chronic HCV genotype 4 infection, including patients without cirrhosis who received ombitasvir plus paritaprevir and ritonavir in combination with ribavirin for 12 weeks (SVR12 100 %) (PEARL-I trial), patients with compensated cirrhosis who received ombitasvir/paritaprevir/ritonavir plus ribavirin for 12 or 16 weeks (SVR12 97 and 98 %) (AGATE-I trial), or Egyptian patients without cirrhosis who received ombitasvir/paritaprevir/ritonavir plus ribavirin for 12 weeks (SVR12 94 %) or with compensated cirrhosis who received ombitasvir/paritaprevir/ritonavir plus ribavirin for 12 or 24 weeks (SVR12 97 and 93 %) (AGATE-II trial). Ombitasvir/paritaprevir/ritonavir was generally well tolerated in patients with chronic HCV genotype 4 infection without cirrhosis or with compensated cirrhosis in clinical trials. There have been postmarketing reports of hepatic decompensation and hepatic failure, which mainly occurred in patients with advanced cirrhosis who received regimens containing ombitasvir/paritaprevir/ritonavir. In conclusion, ombitasvir/paritaprevir/ritonavir is a valuable option for use in patients with chronic HCV genotype 4 infection without cirrhosis or with compensated cirrhosis.
