This study intends to investigate whether addition of PEG-IFN alfa-2a in HBeAg-negative chronic hepatitis B patients who are pretreated with nucleos(t)ide analogues enhances the degree of HBsAg decline.

Condition Intervention Phase

Drug: Peginterferon alfa-2a
Drug: Nucleos(t)ide analogue
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label

  • 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)

  • 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
