Primary

MeasureTime frameDescription
Percentage of Participants Achieving Sustained Virological Response 12 Weeks Post-treatment (SVR12)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.

MeasureTime frameDescription
Change From Baseline in Work Productivity and Activity Impairment (WPAI): PresenteeismBaseline, end of treatment (week 12 or 24 depending on the treatment regimen), and at 12 and 24 weeks after end of treatmentThe 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. Presenteeism indicates the percentage of impairment while working due to health problems.
Percentage of Participants With Sufficient Follow-up Who Achieved Sustained Virological Response 24 Weeks Post-treatment (SVR24)24 weeks after the last dose of study drug (week 36 or 48 depending on the treatment regimen)Sustained virologic response was defined as hepatitis C virus ribonucleic acid (HCV RNA) levels less than 50 IU/mL 24 weeks after the last dose of study drug. The Core population with sufficient follow-up data regarding SVR24 included all core population participants who * had evaluable HCV RNA data ≥ 126 days after the last actual dose of the ABBVIE REGIMEN * or a HCV RNA value ≥ 50 IU/mL at the last measurement post-baseline * or had HCV RNA \< 50 IU/mL at the last measurement post-baseline, but no HCV RNA measurement ≥ 126 days after the last actual dose of the ABBVIE REGIMEN due to reasons related to safety (e.g. dropped out due to adverse event) or virologic failure.
Percentage of Participants Achieving Virological Response at End of TreatmentEnd 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.
Percentage of Participants With RelapseEnd 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.
Number of Participants With Breakthrough12 or 24 weeks (depending on the treatment regimen)Breakthrough was defined as at least one documented HCV RNA \< 50 IU/mL followed by HCV RNA ≥ 50 IU/mL during treatment.
Percentage of Participants in Each Non-response Category 12 Weeks Post-treatment12 weeks after the last dose of study drug (week 24 or 36 depending on the treatment regimen)SVR12 non-response was categorized according to the following: * On-treatment virologic failure (breakthrough \[at least one documented HCV RNA \< 50 IU/mL followed by HCV RNA ≥ 50 IU/mL during treatment\] or failure to suppress \[each measured on-treatment HCV RNA value ≥ 50 IU/mL\]); * Relapse, defined as HCV RNA \< 50 IU/mL at EOT followed by HCV RNA ≥ 50 IU/mL post-treatment in patients who completed treatment (not more than 7 days shortened); * Death; * Premature treatment discontinuation with no on-treatment virologic failure; * None of the above criteria or missing SVR12 data
Percentage of Participants With Adherence to the ABBVIE Regimen, by Adherence CategoryFrom first dose of study drug to end of treatment, 12 to 24 weeks depending on the treatment regimen.Adherence to the ABBVIE treatment regimen is expressed as a percentage of the target dose and was calculated as: Cumulative dose taken / (initial prescribed dose \* planned duration) \* 100 The ABBVIE regimen consists of paritaprevir/r and ombitasvir with or without dasabuvir.
Percentage of Participants With Adherence to Ribavirin by Adherence CategoryFrom first dose of study drug to end of treatment, 12 to 24 weeks depending on the treatment regimenAdherence to ribavirin is expressed as a percentage of the target dose, and was calculated as: Cumulative dose taken / (initial prescribed dose \* planned duration) \* 100
Percentage of Ribavirin Treatment Days in Relation to the Target Number of Ribavirin Treatment DaysFrom first dose of study drug to end of treatment, 12 to 24 weeks depending on the treatment regimen.

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). The VAS assesses overall health on a scale from 0 (worst health imaginable) to 100 (best health imaginable). The higher the score the better the health status.

Percentage of Participants Achieving Sustained Virological Response 12 Weeks Post-treatment (SVR12)

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.

Time frame: 12 weeks after the last dose of study drug (week 24 or 36 depending on the treatment regimen)

Population: The Core population, defined as enrolled participants who were adequately treated according to the standard of care and within local label recommendations for their specific disease characteristics (cirrhotic status, genotype).

Sustained virologic response was defined as hepatitis C virus ribonucleic acid (HCV RNA) levels less than 50 IU/mL 24 weeks after the last dose of study drug. The Core population with sufficient follow-up data regarding SVR24 included all core population participants who * had evaluable HCV RNA data ≥ 126 days after the last actual dose of the ABBVIE REGIMEN * or a HCV RNA value ≥ 50 IU/mL at the last measurement post-baseline * or had HCV RNA \< 50 IU/mL at the last measurement post-baseline, but no HCV RNA measurement ≥ 126 days after the last actual dose of the ABBVIE REGIMEN due to reasons related to safety (e.g. dropped out due to adverse event) or virologic failure.
