E.4 | Principal exclusion criteria |
• Patients who have received any antiviral or IFN based therapy for their chronic hepatitis B before enrolment. • Women with ongoing pregnancy or who are breast feeding. • Evidence of decompensated liver disease including any one of the following: o Serum albumin <3.5 g/L o Prothrombine time ≥4 seconds prolonged o Serum bilirubin > 34 µmol/L o History of encephalopathy o History of variceal bleeding o Ascites • Co-infection with active hepatitis A, hepatitis C, hepatitis D and/or human immunodeficiency virus (HIV) • History or other evidence of a medical condition associated with chronic liver disease other than viral hepatitis (e.g., hemochromatosis, autoimmune hepatitis, metabolic liver disease, alcoholic liver disease, toxin exposures, thalassemia) • Previous or current hepatocellular carcinoma • History of or other evidence of bleeding from oesophageal varices or other conditions consistent with decompensate liver disease • Alpha-fetoprotein levels of > 100 ng/ml.

Current uncontrolled psychiatric disease, especially depression 2. Previous documented suicide attempts 3. Any patient with history of hospitalization for psychiatric disease, or current antidepressant medication or major tranquilizer should be reviewed by consultant psychiatrist regarding suitability for interferon therapy. • 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 • Thyroid disease uncontrolled by prescribed medications • Evidence of severe retinopathy (e.g. CMV retinitis, macular degeneration) • Evidence of drug abuse within one year of study entry • Alcohol intake of more than 3 standard drinks per day for men and 2 standard drinks for women (1 standard drink contains 10 g alcohol) • Patients included in another trial or having been given investigational drugs within 12 weeks prior to screening • Inability or unwillingness to provide informed consent or abide by the requirements of the study, including scheduled blood tests and clinic appointments.

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
Enrolment will be open until the sites have enrolled 45 patients, but not more then 1 year. It is estimated that the first patient could be recruited in December 2006 and the last one in June 2007, but enrolment period will be prolonged, if the targeted number of patients will not be reached by the initially estimated date. End of the study is planned at the end of the year 2008. |
