What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Sustained virological response (SVR)
Time Frame: 36 months
|
The primary outcome measure is the occurence (yes or no) of sustained virologic response (SVR), defined as HCV RNA < the lower limit of quantitation (LLOQ; ie, 15 IU/mL) in serum at least 3 months after stopping therapy.
Point estimates and confidence intervals will be calculated to describe the frequency of SVR in various patients receiving IFN or DAAs based treatment.
|
36 months
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Treatment persistence
Time Frame: 36 months
|
Treatment persistence will be the duration of treatment measured from the first dose of medication until treatment is discontinued.
Reasons for premature discontinuation of treatment will be recorded.
|
36 months
|
Virological breakthrough
Time Frame: 36 months
|
The occurrence of virological breakthrough defined as an increase of HCV RNA by at least 1-log over nadir or to >100 IU if previously undetectable.
|
36 months
|
Liver disease progression
Time Frame: Post treatment 10 years
|
Liver disease progression is a composite endpoint measured by laboratory parameters (alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin, albumin, platelets, prothrombin time (PT) and α-fetoprotein) and observed or reported clinical signs and symptoms.
|
Post treatment 10 years
|
Proportion of participants who develop hepatocellular carcinoma (HCC) through Year 10 by treatment regimen
Time Frame: Post treatment 5 years
|
Post treatment 5 years
