About
The purpose of this study is to evaluate the effect of PEGASYS® (peginterferon alfa-2a 40KD) plus Robatrol® (ribavirin) combination therapy given for 36 weeks versus 48 weeks on the clearance of HCV viremia 24 weeks after treatment end
Full description
Pegylated interferon plus ribavirin brings a good therapeutic response and curability. However, the adverse effects and sufferings are lots. Response-guided, personalized treatment is current principle. In patients of CHC, GT1 PR treatment for 24 weeks is established in rapid virologic responders (RVR) who have low viral load before treatment. As to patients with RVR but high viral load (HVL), the treatment duration is 48 weeks that is the same as patients with complete early virologic response (cEVR). Is a shorter duration of treatment feasible for those with a good virokinetic response? The ideal treatment duration for patients of chronic hepatitis C, GT-1, high viral load with RVR has had no enough data yet. Is it really necessary to double the treatment duration (48 weeks) for patients of chronic hepatitis C, GT-1, high viral load with RVR? Is 36-week adequate for them? A multicenter trial of INDIV-2 was presented at EASL 2010. They treated CHC patients of naïve GT1 HVL and RVR for 30 weeks and got similarly good SVR as those treated for 48 weeks (85% vs. 82%).
Therefore, investigators design a randomized controlled study to investigate the SVR rates between treatment for 36 weeks and for 48 weeks in patients of CHC, GT1, HVL and RVR.

Severe psychiatric disease is defined as treatment with an antidepressant medication or a major tranquilizer at therapeutic doses for major depression or psychosis, respectively, for at least 3 months at any previous time or any history of the following: a suicidal attempt, hospitalization for psychiatric disease, or a period of disability due to a psychiatric disease
History of a severe seizure disorder or current anticonvulsant use
History of immunologically mediated disease, chronic pulmonary disease associated with functional limitation, severe cardiac disease, major organ transplantation or other evidence of severe illness, malignancy, or any other conditions which would make the patient, in the opinion of the investigator, unsuitable for the study
Evidence of severe retinopathy (e.g. CMV retinitis, macula degeneration) or clinically relevant ophthalmological disorder (e.g. due to diabetes mellitus or hypertension)
