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 20, 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.

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.
Number of Participants in Each Non-response Category 12 Weeks Post-treatment12 weeks after the last dose of study drug (week 20, 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; * Insufficient virological response reported or HCV RNA ≥ 50 IU/mL post-EOT and none of the above criteria * Missing SVR12 data and/or none of the above criteria.

Change From Baseline in EuroQol 5 Dimension 5 Level (EQ-5D-5L) Index ScoreBaseline, end of treatment (week 8, 12, or 24 depending on the treatment regimen), and at 12 and 24 weeks after end of treatmentThe 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.

The VAS assesses overall health on a scale from 0 (worst health imaginable) to 100 (best health imaginable).

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.

Change From Baseline in Beliefs Medication Questionnaire - (18-item BMQ)Baseline and end of treatment (week 8, 12, or 24 depending on the treatment regimen)The BMQ consists of 2 sections and 18 questions to screen for patients' beliefs, attitudes and concerns about their medication. The BMQ-Specific section comprises two 5-item subscales assessing the necessity of and concerns about the prescribed medication (Specific-Necessity and Specific-Concerns). The BMQ-General section comprises two 4-item subscales assessing beliefs that medicines are harmful and overused by doctors in general (General-Harm and General-Overuse). The 18 items are rated on a Likert scale from 1 (strongly disagree) to 5 (strongly agree). Each subscale score ranges from 1 to 5. High scores in the Specific-Concerns scale represent the notion that adverse reactions are potentially harmful when taking medication on a regular basis, and high scores in the Specific-Necessity scale indicate the patient's need to adhere to medication to maintain health. High scores in the General-Harm and General-Overuse scales represent an overall negative perception of medication.
Change From Baseline in Patient Activation Measure 13 (PAM-13)Baseline and end of treatment (week 8, 12, or 24 depending on the treatment regimen)PAM 13 is a measure used to assess the patient knowledge, skill, and confidence for self-management, consisting of 13 questions. Each of the 13 items can be answered with one of four possible response options, which are disagree strongly (1), disagree (2), agree (3), agree strongly (4). Scores were summed to calculate the overall raw score, then transformed to a scale with a theoretical range 0 to 100, based on calibration tables, with higher PAM scores indicating higher patient activation.
Number of Participants With Outpatient Consultations Due to Liver Disease by CategoryFrom first dose of study drug through 30 days after last dose (12 to 28 weeks depending on treatment regimen). The median (minimum, maximum) duration of treatment was 84 (4, 167) days.

The FIS consists of 40 items, each of which is scored 0 (no problem) to 4 (extreme problem), providing a total score from of 0 to 160, where a lower score = less fatigue impact

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 20, 24, or 36 depending on the treatment regimen)

Population: The Core population includes 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).

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. Total activity impairment (TAI) indicates the percentage of general (non-work) activity impairment due to health problems.

Time frame: Baseline, end of treatment (week 8, 12, or 24 depending on the treatment regimen), and at 12 and 24 weeks after end of treatment

Population: The Core population with available data at baseline and each time point.
