Percentage of Participants With Sustained Virologic Response 12 Weeks Post-treatment (SVR12)
Tidsramme: 12 weeks after the last actual dose of study drug
|
SVR12 was defined as plasma hepatitis C virus ribonucleic acid (HCV RNA) level less than the lower limit of quantification [<LLOQ]) 12 weeks after the last dose of study drug.
Participants with missing data were counted as failures.

Hepatitis C Virus Patient-Reported Outcomes Instrument (HCV-PRO) Total Score: Change From Baseline to 12 Weeks After the Last Dose of Study Drug
Tidsramme: Day 1 (Baseline), 12 weeks after the last actual dose of the study drug
|
The HCV-PRO has been developed to capture the function and well-being impact of HCV conditions and treatment and contains 16 items important to HCV-infected patients; items were totaled to a summary score.
Scores range from 0 to 100.
A higher HCV-PRO score indicates a better state of health and a decrease from baseline represents worsening.
If a participant answered at least 12 of the 16 items, the missing items were imputed with the mean score of the answered items; if a participant did not answer at least 12 of the items, the total score was considered missing.

Short-Form 36 Version 2 Health Survey (SF-36v2) Physical Component Summary (PCS) Scores: Change From Baseline to 12 Weeks After the Last Dose of Study Drug
Tidsramme: Day 1 (Baseline), 12 weeks after the last actual dose of the study drug
|
The SF-36v2 is a non-disease specific Health Related Quality of Life (HRQoL) instrument.
The SF-36v2 comprises 36 total items (questions) targeting a subject's functional health and well-being in 8 domains (physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotional and mental health) with a recall period of four weeks.
Domain scores are aggregated into a Physical Component Summary (PCS) score and a Mental Component Summary (MCS) score.
SF-36v2 scores range from 1-100: higher scores indicate a better state of health and a decrease from baseline represents worsening.
If a participant answered at least 50% of the items in a multi-item scale of the SF-36v2, the missing items were imputed with the average score of the answered items in the same domain.
In cases where the participant did not answer at least 50% of the items, the score for that domain was considered missing.
The SF-36v2 MCS and PCS scores were not computed if any domain
