What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentages of Participants With Sustained Virologic Response 12 Weeks Post-Treatment (SVR12) in Group 1 and in Group 2
Time Frame: 12 weeks after the last actual dose of study drug
SVR12, defined as HCV RNA < lower limit of quantification (LLOQ) in the SVR12 window (12 weeks after the last actual dose of study drug) without any confirmed quantifiable (≥ LLOQ) post-treatment value before or during that SVR window. Flanking imputation: for participants with missing HCV RNA at a visit who have an undetectable HCV RNA or unquantifiable HCV RNA at the preceding visit and the succeeding visit, the missing value was imputed as undetectable or unquantifiable. For SVR analyses, if there was no value in the window after the flanking imputation but there was an HCV RNA value after the window, then it was imputed into the SVR window. After above imputations were applied, if there was still no value in the window but there was an HCV RNA value from a local laboratory present, then it was imputed into the SVR window. Otherwise, participants with missing data were counted as failures. The 95% confidence interval was calculated using the Wilson score method.
12 weeks after the last actual dose of study drug

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With SVR12 in Group 3
Time Frame: 12 weeks after the last actual dose of study drug
SVR12, defined as HCV RNA < LLOQ in the SVR12 window (12 weeks after the last actual dose of study drug) without any confirmed quantifiable (≥ LLOQ) post-treatment value before or during that SVR window. Flanking imputation: for participants with missing HCV RNA at a visit, who have an undetectable HCV RNA or unquantifiable HCV RNA at the preceding visit and the succeeding visit, the missing value was imputed as undetectable or unquantifiable. For SVR analyses, if there was no value in the window after the flanking imputation but there was an HCV RNA value after the window, then it was imputed into the SVR window. After above imputations were applied, if there was still no value in the window but there was an HCV RNA value from a local laboratory present, then it was imputed into the SVR window. Otherwise, participants with missing data were counted as failures.
12 weeks after the last actual dose of study drug
Percentage of Participants With SVR12 Non-Response Due to Experiencing On-Treatment Virologic Failure
Time Frame: Up to 24 weeks during treatment
On-treatment virologic failure was defined as: confirmed HCV RNA ≥ LLOQ after HCV RNA < LLOQ during treatment; confirmed increase from nadir in HCV RNA (two consecutive HCV RNA measurements > 1 log˅10 IU/mL above nadir) at any time point during treatment; or HCV RNA ≥ LLOQ persistently during treatment with at least 6 weeks (≥ 36 days) of treatment. The 95% confidence interval was calculated using Wilson score method. SVR12 was defined as HCV RNA < LLOQ in the SVR12 window (12 weeks after the last actual dose of study drug) without any confirmed quantifiable (≥ LLOQ) post-treatment value before or during that SVR window.
Up to 24 weeks during treatment
Percentage of Participants With SVR12 Non-Response Due to Experiencing Relapse˅12
Time Frame: Up to 12 weeks after the last actual dose of study drug
Relapse˅12 was defined as confirmed HCV RNA ≥ LLOQ between end of treatment and 12 weeks after last actual dose of active study drug (up to and including the SVR12 window) for a participant with HCV RNA < LLOQ at final treatment visit who completes treatment and has post-treatment HCV RNA data. Completion of treatment was defined as a study drug duration ≥ 77 days for participants assigned to 12 weeks of treatment or ≥ 154 days for participants assigned to 24 weeks of treatment. SVR12 was defined as HCV RNA < LLOQ in the SVR12 window (12 weeks after the last actual dose of study drug) without any confirmed quantifiable (≥ LLOQ) post-treatment value before or during that SVR window. The 95% confidence interval was calculated using the Wilson score method.
Up to 12 weeks after the last actual dose of study drug
Percentage of Participants With Improvement From Baseline to Post-Treatment Week 12 in Hepatic Function Tests
Time Frame: Up to post-treatment Week 12

Improvement was defined as:

  • increase of more than 0.2 g/L from baseline to post-treatment Week 12 in albumin
  • decrease of more than 0.3 µmol/L from baseline to post-treatment Week 12 in bilirubin
  • decrease of more than 5 ng/mL from baseline to post-treatment Week 12 in alpha-fetoprotein
  • increase of more than 15*10^9/L from baseline to post-treatment Week 12 in platelet count
  • decrease of more than 0.2 from baseline to post-treatment Week 12 in international normalized ratio.
Up to post-treatment Week 12
Percentage of Participants With Improvement From Baseline to Post-Treatment Week 12 in FibroTest
Time Frame: Up to post-treatment Week 12
The FibroTest score is used to assess liver fibrosis. Scores range from 0.00 to 1.00, with higher scores indicating a greater degree of fibrosis. Improvement was defined as a decrease of more than 0.2 from baseline to post-treatment Week 12.
Up to post-treatment Week 12
Percentage of Participants With Improvement From Baseline to Post-Treatment Week 12 in Chld-Pugh Score
Time Frame: Up to post-treatment Week 12
The The Child-Pugh score uses five clinical measures of liver disease (3 laboratory parameters and 2 clinical assessments) to measure severity of cirrhosis. Scores range from 5 to 15, with higher scores indicating more severity. Improvement was defined as a decrease of 1 or more from baseline to post-treatment Week 12.
Up to post-treatment Week 12
Percentage of Participants With Improvement From Baseline to Post-Treatment Week 12 in Model for End-Stage Liver Disease (MELD) Score
Time Frame: Up to post-treatment Week 12
MELD is a scoring system for assessing the severity of chronic liver disease. Scores range from 6 to 40, with higher scores indicating more severity. Improvement was defined as a decrease of 1 or more from baseline to post-treatment Week 12.
Up to post-treatment Week 12
