A Phase IV Trial of Paritaprevir/Ritonavir, Ombitasvir, Dasabuvir for Chronic Hepatitis C Genotype 1 Virus Infection

Summary

A total of 100 people with chronic HCV and recent injection drug use or recipients of opioid substitution therapy will be enrolled in 5 countries and 21 study sites. Participants with genotype 1a infection or cirrhosis will receive 12 weeks of open-label paritaprevir/ritonavir/ombitasvir and dasabuvir ("3D"), and twice-daily ribavirin. Participants with genotype 1b infection without cirrhosis will receive 12 weeks of open-label "3D". The study consists of a screening phase (6 weeks), treatment phase (12 weeks) and follow-up phase (96 weeks) to evaluate treatment response and reinfection.
