Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Incident rate of drug-related adverse events (pruritus, headache, nausea, fatigue, elevated bilirubin, and elevated ALT) For evaluation of adverse events, we use "Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 (Japanese version)" | — |
Secondary
| Measure | Time frame |
|---|---|
| [Secondary outcomes of efficacy] As secondary outcomes of efficacy, we evaluate the percentage of subjects achieving a 12-week sustained virologic response (SVR12), the percentages of subjects with on-treatment virologic failure, the percentages of subjects with post-treatment relapse, the percentage of subjects achieving a SVR4 and quality of life (QOL) score of subjects. [Secondary outcomes of safety] As secondary outcomes of safety, we evaluate the discontinuation rate due to adverse events. For evaluationof adverse events, we use "Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 (Japanese version)". | — |
