简要总结
Chronic hepatitis C infection is one of the leading causes of chronic liver disease in the United States. Approximately one-third of patients with hepatitis C infection develop cirrhosis of the liver, which can lead to liver failure or liver cancer. The current treatment for hepatitis C infection in previously untreated patients is successful in only about half of patients. There is no established therapy for non-responders.
This is a randomized, double-blinded, multicenter trial to determine the effectiveness of thymosin alpha 1 (thymalfasin) 1.6 mg twice weekly plus PEGinterferon alfa-2a 180 ug/wk compared to placebo plus PEGinterferon alfa-2a in adults with chronic hepatitis C without cirrhosis who are non-responders to previous treatment with interferon or interferon plus ribavirin. The definition of non-response requires a positive HCV RNA test at the end of a course of at least 12 weeks of therapy. Patients will receive treatment for 12 months, and will be followed-up for a further 6 months after the end of therapy.

入选标准
- •Signed written informed consent.
- •Age over 18 years old.
- •Presence of HCV RNA measured by qualitative PCR.
- •Nonresponder to a previous course of therapy with either IFN alone or IFN plus ribavirin. The patient must have been treated for at least 12 weeks.
- •Washout period of at least 6 months from previous therapy with IFN alone or IFN plus Ribavirin.
- •Liver biopsy consistent with chronic hepatitis C within the last 12 months before treatment starts, and at least 6 months after the end of the prior failed therapy.
- •No clinical or histological evidence of cirrhosis (METAVIR fibrosis score 0 to 3).
- •Compensated liver disease with prothrombin time prolonged less than 3 seconds over control, serum albumin stable and within normal limits, total bilirubin < 2 mg/dl, and no history of hepatic encephalopathy, esophageal varices or ascites.
- •Ultrasound, CT scan, or MRI of the liver within 3 months of entry negative for HCC.
- •Hematocrit > 30%, platelet count > 100 x 109/L, WBC > 3 x 109/L, and polymorphonuclear white cell count > 1.5 x 109/L.
- •Adequate renal function as demonstrated by serum creatinine level < 2.0 mg/dL.
- •Normal TSH or adequately controlled thyroid function.
- •If the patient is a woman, she is using a definitive method of birth control in consultation with her physician, or is surgically sterile or post-menopausal.
排除标准
- •Use of systemic corticosteroids within 6 months of entry.
- •Current use of any drug known to be hepatotoxic, any drug (other than the study drugs) known to have or suspected of having therapeutic activity in hepatitis C or of any immunosuppressive drug (including corticosteroids).
- •Any other liver disease including hepatitis B, hepatitis delta, alcoholic liver disease, drug-induced liver injury, primary biliary cirrhosis, sclerosing cholangitis, autoimmune hepatitis, hemochromatosis, alpha 1-antitrypsin deficiency, or Wilson's disease.
- •Alpha-fetoprotein > 200 ng/mL.
- •Current or past diagnosis of cirrhosis.
- •Evidence of portal hypertension either by Doppler ultrasonography or gastrointestinal endoscopy.
- •Decompensated liver disease based on a history of hepatic encephalopathy, esophageal varices, or ascites.
- •HIV infection diagnosed by HIV seropositivity and confirmed by Western blot.
- •Concomitant or prior history of malignancy other than curatively treated skin cancer or surgically cured in situ carcinoma of the cervix.
- •Active infectious process other than HCV that is not of a self-limited nature (eg. TB or AIDS).
- •Rheumatoid arthritis or other autoimmune disease (serum ANA > 1:160).
- •Pregnancy as documented by a urine pregnancy test.
- •Alcohol or intravenous drug abuse within the previous 1 year.
- •Chronic use of methadone.
- •Patients who are poor medical risk or who have any non-malignant systemic disease that, in the opinion of the investigator, would make it unlikely that the patient could complete the protocol.
- •Patients with a history of severe depression that required either hospitalization or electroshock therapy; or depression associated with suicide attempt.
- •Patients with significant pre-existing cardiac or pulmonary disease.
- •Any indication that the patient would not comply with the conditions of the study protocol.
- •Previous treatment with thymosin alpha
- •Patients with known hypersensitivity to IFNa.
- •Simultaneous participation in another investigational drug study, or participation in any clinical trial involving investigational drugs with 3 months before study entry.
- •Family history of intracerebral hemorrhage.
