Developmental phase



Assessment

Primary outcomes

Negative results of qualitative HCV RNA test at weeks 4, 12, 24, and 48 during treatment and 24 weeks after terminating therapy.

Key secondary outcomes

1. Normalization of alanine aminotransferase levels at weeks 24 and 48 during treatment and 24 weeks after terminating therapy.
2. Adverse event and laboratory abnormality (changes in neutrophil count, platelet count, and hemoglobin concentration).
3. The incidence rates of completion of therapy, dose reduction, and discontinuation of therapy.
4. Assessment of quality of life.
5. HCV Core and NS5A ISDR amino acid replacement and virological response.

Interventions/Control_1

Starting with a standard dose of ribavirin in combination with peginterferon alpha-2a, followed by ribavirin reduction by 200 mg/day upon a decline of hemoglobin concentration by 2 g/dL or more from baseline at week 2 of therapy.

Interventions/Control_2

Starting with a ribavirin dose according to the ribavirin apparent clearance in combination with peginterferon alpha-2a, followed by stepwise dose-escalation by 100 mg/day in cases starting with a lower dose of ribavirin and hemoglobin concentration at or above 12 g/dL at week 4 and 8 of therapy.
