Outcome Measures

Primary Outcomes (1)

  • Sustained Virologic Response Depending on the Dosage of Peginterferon Alfa 2a

    We investigate whether the SVR between 100% and 80% group of peginterferon alfa 2a is not different.

    post treatment 24 weeks

Secondary Outcomes (1)

  • IL28B Polymorphism Effect on SVR

    post treatment 24 weeks

Study Arms (2)

80% dosage group of peginterferon alfa 2a

EXPERIMENTAL

This group patients will treated the same full dose (180ug/week) of peginterferon alfa 2a during the first 12 weeks and then reduce the 75% dose (135ug/week) of peginterferon alfa 2a during remnant 36 weeks. At a result, these patients treated with 80% dosage of originally prescribed peginterferon alfa-2a for standard 48 weeks of treatment.

Drug: peginterferon alfa 2a (pegasys)

100% dosage group of peginterferon alfa 2a

ACTIVE COMPARATOR

These group patients would be treated with standard dose 180 ug/week for 48 weeks.

Drug: peginterferon alfa-2a (pegasys)

Interventions

dosage form; 180ug/week during first 12 weeks and then 135 ug/week during 36 weeks otherwise unremarkable

Also known as: Roche
80% dosage group of peginterferon alfa 2a

These patients would be treated with standard dose 180ug /week for 48 weeks. In general, the patient with CHC genotype 1is guided with treatment with pegasys 180ug /week and ribavirin 1000-1200 mg/day for 48 weeks. We do not make intervention of ribavirin dose.

Also known as: Roche
100% dosage group of peginterferon alfa 2a
