History of Changes

Purpose

The outcome of treatment of chronic hepatitis B is determined by viral and host interaction, thus the combination therapy of immunomodulator (PEG-IFN) and potent antiviral drug (entecavir) should improve the response rate. In addition, the simultaneous assessment of viral and host genetic factors associated with SVR may help to identify predictors of treatment outcomes, which will in turn significant reduce the cost/effect of therapy

Condition	Intervention
Chronic Hepatitis B	Drug: PEG-IFN and entecavir

Primary Outcome Measures:

To determine whether a combination of PEG-IFN and entecavir improves the rate of sustained response and HBsAg clearance in patients with HBeAg-negative chronic hepatitis B [ Time Frame: 24 weeks post treatment ]

Secondary Outcome Measures:

To determine host factors and viral factors associated with response to PEG-IFN alone or PEG-IFN plus entecavir treatment [ Time Frame: 24 weeks post treatment ]


Estimated Enrollment:	126
Study Start Date:	March 2011
Estimated Study Completion Date:	December 2013
Estimated Primary Completion Date:	May 2013 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Active Comparator: drug combination	Drug: PEG-IFN and entecavir The patients will be randomized in approximately 1:1 ratio into one of 2 treatment regimens; to receive PEG-IFN alpha-2b (1.5 microgram/kg/week) plus entecavir (0.5 mg/day) or PEG-IFN alpha-2b (1.5 microgram/kg/week) alone for 48 weeks by using pre-generated randomization schedule.

Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

Men and women 18 to 65 years of age
Patients with HBeAg-negative chronic hepatitis B
Positive for HBsAg for at least 6 months, negative for anti-HBs and HBeAg
Serum HBV DNA levels ≥ 2,000 IU/mL at screening
Increased alanine aminotransferase (ALT) levels [greater than the upper limit of normal (ULN) and less than 10xULN}
No signs or symptoms of advanced liver disease
Patient has had a liver biopsy within 1 year of screening

Exclusion Criteria:

Patient had previous treatment with IFN, peg-IFN, and/or entecavir
Patient has evidence or history of chronic hepatitis not caused by HBV, including but not limited to nonalcoholic steatohepatitis (NASH), drug-induced hepatitis, and autoimmune hepatitis
Patient has co-infection with hepatitis C virus and/or human immunodeficiency virus
Patients with liver cancer
Female patient is pregnant, lactating, expecting to conceive or donate eggs, or is of childbearing potential throughout treatment.
Patient has any other condition that is contraindicated for treatment with PEG-IFN or entecavir
Patient has any condition or pre-study laboratory abnormality, or history of any illness, which in the opinion of the investigator, might confound the results of the study or pose additional risk in administering the study drug
