Eligibility Criteria

18 Years - 80 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Male and female patients >18 years of age
  • Patients have never been treated with traditional interferon plus ribavirin or peginterferon plus ribavirin
  • Serologic evidence of chronic hepatitis C infection by an anti-HCV antibody test
  • Detectable serum HCV-RNA

  • All fertile males and females receiving ribavirin must be using two forms of effective contraception during treatment and during the 6 months after treatment end

Exclusion Criteria:

  • Women with ongoing pregnancy or breast feeding
  • Present therapy with any systemic anti-neoplastic or immunomodulatory treatment (including supraphysiologic doses of steroids and radiation) within 6 months prior to the first dose of study drug
  • Any investigational drug 6 weeks prior to the first dose of study drug
  • Co-infection with active hepatitis A, hepatitis B and/or human immunodeficiency virus (HIV)

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, or any other conditions which would make the patient, in the opinion of the investigator, unsuitable for the study
  • History of thyroid disease poorly controlled on prescribed medications, elevated thyroid stimulating hormone (TSH) concentrations with elevation of antibodies to thyroid peroxidase and any clinical manifestations of thyroid disease
  • Evidence of severe retinopathy (e.g. CMV retinitis, macula degeneration)
  • Evidence of drug abuse (including excessive alcohol consumption>40 g/day) within one year of study entry

  • Hgb <11 g/dL in women or <12 g/dL in men at screening
  • Any patient with major thalassemia
  • Patients with documented or presumed coronary artery disease or cerebrovascular disease should not be enrolled if, in the judgment of the investigator, an acute decrease in hemoglobin by up to 4 g/dL (as may be seen with ribavirin therapy) would not be well-tolerated
  • Evidence or history of hepatocellular carcinoma
  • Local or Systemic malignancy unstable status

5. Study Description

Brief Summary
Our previous collaborative studies has developed a molecular diagnosis tool, which is characterized with a prediction model consisting single nucleotide polymorphisms (SNPs), for assessing the efficacy of interferon combined therapy for chronic hepatitis C (CHC) patients prior to treatment. Aims of this project: To analyze and validate the gene expression profiling dependent of treatment response to peg-interferon-α plus ribavirin combination therapy in CHC genotype-1 patients. To select the candidate genes and establish a monitoring model assessing the efficacy of interferon treatment.
Detailed Description
A combination of pegylated-interferon (PEG-IFN) with ribavirin has been the choice for treating chronic hepatitis C (CHC) patients. In addition to the high cost, the treatment takes 6 to 12 months and often brings significant adverse reactions to some patients. It would therefore be beneficial to include a pre-treatment evaluation and post-treatment monitoring system to maximize the efficacy of CHC therapy. We have established a molecular diagnosis tool for assessing the efficacy of interferon combined therapy for CHC patients prior to treatment. This diagnostic tool is characterized with a prediction model consisting single nucleotide polymorphisms (SNPs) strongly associated with interferon efficacy in treating CHC patients. The prediction model has been validated by hepatitis C samples in Taiwan, and it achieved 80 % accuracy, higher than the current efficacy rates. Supplemented with the viral genotype information would further increase the prediction accuracy to 85%. In this project, we aim to analyze patients' gene expression profiling during the treatment. The current study will focus on 30 PEG-IFN and ribavirin treated patients with HCV genotype 1 infection. After the responding status of those patients has been confirmed, we will compare gene expression profiling among the different responses before and during treatment. By using this information, we can properly select the candidate genes, and establish a monitoring model with these biomarkers. This monitoring model can thus be applied to assess the efficacy of PEG-IFN plus ribavirin combination treatment.
