Outcomes

Primary Outcome Measures

Percentage of Participants With Sustained Virologic Response 12 Weeks After Discontinuation of Therapy (SVR12)
SVR12 was defined as HCV RNA < the lower limit of quantitation (LLOQ) 12 weeks following the last dose of study drug.
Percentage of Participants Who Permanently Discontinued Any Study Drug Due to an Adverse Event

Secondary Outcome Measures

Percentage of Participants With Sustained Virologic Response 4 Weeks After Discontinuation of Therapy (SVR4)
SVR4 was defined as HCV RNA < the LLOQ 4 weeks following the last dose of study drug.
Percentage of Participants With HCV RNA < LLOQ on Treatment
HCV RNA Change From Baseline
Percentage of Participants With Virologic Failure
Virologic failure was defined as On-treatment virologic failure HCV RNA ≥ LLOQ after having previously had HCV RNA < LLOQ, while on treatment, > 1 log10 IU/mL increase in HCV RNA from nadir while on treatment, HCV RNA persistently ≥ LLOQ through 8 weeks of treatment (ie nonresponse) Relapse HCV RNA ≥ LLOQ during the posttreatment period having achieved HCV RNA < LLOQ at end of treatment, confirmed with 2 consecutive values or last available posttreatment measurement
Change From Pretreatment Assessment in Health-related Quality of Life as Evaluated by Short Form (SF-36) Health Survey Scale- Physical Component Score
The SF-36 Health Survey is a self-reporting, multi-item scale measuring 8 health concepts: 1) physical functioning, 2) role limitations due to physical health problems, 3) bodily pain, 4) general health, 5) vitality (energy/fatigue), 6) social functioning, 7) role limitations due to emotional problems and 8) mental health (psychological distress and psychological well-being). The first 6 concepts constitute the physical component summary. The total score is an average of the individual question scores, which are scaled 0-100 with lower scores representing more disability and higher scores representing less disability.

The SF-36 Health Survey is a self-reporting, multi-item scale measuring 8 health concepts: 1) physical functioning, 2) role limitations due to physical health problems, 3) bodily pain, 4) general health, 5) vitality (energy/fatigue), 6) social functioning, 7) role limitations due to emotional problems and 8) mental health (psychological distress and psychological well-being). The last 5 concepts constitute the mental component summary. The total score is an average of the individual question scores, which are scaled 0-100 with lower score representing more disability and higher scores representing less disability.
Change From Pretreatment Assessment in Health-related Quality of Life as Evaluated by Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F)
The FACIT-Fatigue score was measured using a 40-item questionnaire that assesses self-reported fatigue and its impact upon daily activities and function. Participants scored each item on a 5-point scale from 0 (Not at all) to 4 (Very much). The FACIT-F total score was calculated by taking the sum of all 40 individual scores and ranged from 0-160, with higher scores indicating better quality of life.
