Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
The primary objectives of the study are to evaluate the efficacy, safety, and tolerability of treatment with sofosbuvir/velpatasvir/voxilaprevir (Vosevi®; SOF/VEL/VOX) fixed-dose combination (FDC) for 12 weeks and of sofosbuvir/velpatasvir (Epclusa®; SOF/VEL) FDC for 12 weeks in direct-acting antiviral (DAA)-experienced adults with chronic hepatitis C virus (HCV) infection with or without cirrhosis who have not received prior treatment with a regimen containing an inhibitor of the HCV NS5A protein.
