Brief Summary:

Treatment with a nucleoside analogue and subsequent viral decline has shown to partially restore immune hyporesponsiveness in chronic hepatitis B patients. Recent pilot studies investigating whether the effect of lowering viral load with nucleoside analogue therapy prior to the initiation of peginterferon results in higher sustained off-treatment responses showed contradictory findings.

The aim of this study is to investigate sustained off-treatment response to peginterferon alfa-2b in chronic HBeAg-positive hepatitis B patients who are pretreated with nucleos(t)ide analogues, thereby lowering viral load

Exclusion Criteria:

  • Treatment with any investigational drug within 30 days of entry to this protocol
  • Severe hepatitis activity as documented by ALT>10 x ULN
  • History of decompensated cirrhosis (defined as jaundice in the presence of cirrhosis, ascites, bleeding gastric or esophageal varices or encephalopathy)
  • Pre-existent neutropenia (neutrophils <1,800/mm3) or thrombocytopenia (platelets <90,000/mm3)
  • Co-infection with hepatitis C virus, hepatitis D virus or human immunodeficiency virus (HIV)

  • Alpha fetoprotein > 50 ng/ml
  • Hyper- or hypothyroidism (subjects requiring medication to maintain TSH levels in the normal range are eligible if all other inclusion/exclusion criteria are met)
  • Immune suppressive treatment within the previous 6 months
  • Contra-indications for alfa-interferon therapy like suspected hypersensitivity to interferon or Peginterferon or any known pre-existing medical condition that could interfere with the patient's participation in and completion of the study.
  • Pregnancy, breast-feeding
  • Other significant medical illness that might interfere with this study: significant pulmonary dysfunction in the previous 6 months, malignancy other than skin basocellular carcinoma in previous 5 years, immunodeficiency syndromes (e.g. HIV positivity, auto-immune diseases, organ transplants other than cornea and hair transplant)
  • Any medical condition requiring, or likely to require chronic systemic administration of steroids, during the course of the study
  • Substance abuse, such as alcohol (>80 g/day), I.V. drugs and inhaled drugs in the past 2 years.
  • Any other condition which in the opinion of the investigator would make the patient unsuitable for enrollment, or could interfere with the patient participating in and completing the study
