Effectiveness of Paritaprevir/r - Ombitasvir, ± Dasabuvir, ± Ribavirin in Patients With Chronic Hepatitis C in Canada

This was a prospective, multi-center observational study in participants receiving the interferon-free ABBVIE REGIMEN ± RBV in Canada. The prescription of a treatment regimen was at the discretion of the physician in accordance with local clinical practice and label, was made independently from this observational study and preceded the decision to offer the participant the opportunity to participate in this study. Adults chronically infected with HCV, receiving the interferon-free ABBVIE REGIMEN, were offered the opportunity to participate in this study during a routine clinical visit at the participating sites. Follow-up visits, treatment, procedures, and diagnostic methods followed physicians' routine clinical practice. Data were collected at the following time windows: baseline, early on-treatment visit, mid-treatment visit (for participants with a treatment duration of 24 weeks), end of treatment (EoT), early post-treatment and 12 and 24 weeks after the end of treatment (representing sustained virologic response 12 weeks after the end of treatment \[SVR12\] and sustained virologic response 24 weeks after the end of treatment \[SVR24\]).
