Real World Evidence of the Effectiveness of Paritaprevir/r - Ombitasvir, ± Dasabuvir, ± Ribavirin and Patient Support Program in Patients With Chronic Hepatitis C (3DUTCH)
Real World Evidence of the Effectiveness of Paritaprevir/r - Ombitasvir, ± Dasabuvir, ± Ribavirin in Patients With Chronic Hepatitis C - An Observational Study in The Netherlands (3DUTCH)
The interferon-free combination regimen of paritaprevir/r - ombitasvir with or without dasabuvir (ABBVIE REGIMEN) ± ribavirin (RBV) for the treatment of chronic hepatitis C (CHC) has been shown to be safe and effective in randomized controlled clinical trials with strict inclusion and exclusion criteria under well controlled conditions.
This observational study is the first effectiveness research examining the ABBVIE REGIMEN ± RBV, used according to local label, under real world conditions in the Netherlands in a clinical practice patient population.

Paritaprevir/Ritonavir + Ombitasvir ± Dasabuvir ± Ribavirin
Participants in this observational study received treatment with paritaprevir/ritonavir (r) and ombitasvir with or without dasabuvir ± ribavirin (RBV) for 12 or 24 weeks for the treatment of chronic hepatitis C (CHC), according to hepatitis C virus (HCV) genotype/subtype and stage of liver disease. The prescription of 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 patient the opportunity to participate in this study. |
What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of Participants Achieving Sustained Virological Response 12 Weeks Post-treatment (SVR12)
Time Frame: 12 weeks after the last dose of study drug (week 24 or 36 depending on the treatment regimen)
|
Sustained virologic response was defined as hepatitis C virus ribonucleic acid (HCV RNA) levels less than 50 IU/mL 12 weeks after the last dose of study drug.
Participants with missing HCV RNA were counted as virological failure.
|
12 weeks after the last dose of study drug (week 24 or 36 depending on the treatment regimen)
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of Participants Achieving Virological Response at End of Treatment
Time Frame: End of treatment (week 12 or 24 depending on the treatment regimen)
|
Virologic response was defined as hepatitis C virus ribonucleic acid (HCV RNA) levels less than 50 IU/mL.
|
End of treatment (week 12 or 24 depending on the treatment regimen)
|
Percentage of Participants With Relapse
Time Frame: End of treatment (week 12 or 24 depending on the treatment regimen) and up to 24 weeks after the end of treatment.
|
Relapse was defined as participants with a virologic response (VR; HCV RNA < 50 IU/mL) at end of treatment (EOT) followed by HCV RNA ≥ 50 IU/mL at any time after the end of treatment.
|
End of treatment (week 12 or 24 depending on the treatment regimen) and up to 24 weeks after the end of treatment.
|
Change From Baseline in EuroQol 5 Dimension 5 Level (EQ-5D-5L) Index Score
Time Frame: Baseline, end of treatment (week 12 or 24 depending on the treatment regimen), and at 12 and 24 weeks after end of treatment
|
The EQ-5D-5L is a health state utility instrument that evaluates preference for health status. The 5 items in the EQ-5D-5L comprise 5 dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) each of which are rated on 5 levels of severity (1: indicating no problem, 2: indicating slight problems, 3: indicating moderate problems, 4: indicating severe problems, 5: indicating extreme problems), and a separate visual analog scale (VAS). Responses to the 5 dimension scores were combined and converted into a single preference-weighted health utility index score by applying country-specific weights.The range for EQ-5D-5L index score is 0 to 1 where '0' is defined as a health state equivalent to being dead and '1' is full health.The higher the score the better the health status. |
Baseline, end of treatment (week 12 or 24 depending on the treatment regimen), and at 12 and 24 weeks after end of treatment
|
Change From Baseline in Work Productivity and Activity Impairment (WPAI): Absenteeism
Time Frame: Baseline, end of treatment (week 12 or 24 depending on the treatment regimen), and at 12 and 24 weeks after end of treatment
|
The WPAI Hepatitis C V2.0 is an HCV specific questionnaire used to measure work absenteeism, work presenteeism, and daily activity impairment. Respondents were asked about time missed from work and time while at work during which productivity was impaired in the past seven days. Results of WPAI are expressed as a percentage of impairment from 0 to 100, with higher percentages indicating greater impairment and less productivity. Absenteeism indicates the percentage of work time missed due to health problems. |
