Detailed Description:
This multicenter, randomized, controlled study will be conducted by the pediatric centers within the NIDDK-sponsored Hepatitis B Research Network (HBRN). Children age 3-<18 years with immunotolerant chronic hepatitis B (CHB) infection who fulfill the entry criteria will be randomized in a 1:1 ratio to one of two groups. The treated group will receive entecavir as monotherapy for 8 weeks and then combination therapy with entecavir and pegylated interferon by weekly subcutaneous injection until week 48. Children in the control group will receive standard of care which is no active treatment. All children will be followed for 96 weeks which is 48 weeks after discontinuation of therapy in the treatment group. Those children initially randomized to the control group will be offered compassionate combination therapy once all data for the primary outcome are analyzed if combination therapy is shown to be efficacious for the primary outcome.
Assessment in the treatment group will be undertaken at baseline, weeks 4, 8, 10, 12, 14, 16 then every 4 weeks until week 48, and then at week 52, 56, 60, 72, 84 and 96. Assessments in the control group will be undertaken at baseline, weeks 8, 12, 20, 32, 48, 72, and 96. Data collected will describe baseline demographics, symptoms of liver disease, intercurrent illnesses, and findings on physical examination. Blood work will be drawn to measure markers of viral and liver disease status, assessment of drug adverse effects, and for storage.
Participants in the treatment group will continue on therapy until week 48 and complete the full study follow-up protocol thereafter, including those who undergo seroconversion to anti-HBe or anti-HBs before reaching week 48. Participants in either group who experience a sustained elevation of ALT will be eligible to receive treatment as recommended by their hepatologist and will continue to complete the study follow-up protocol. Participants who exhibit adverse effects of therapy will undergo dose adjustment or discontinuation of therapy as detailed in the protocol, and will continue to complete the study follow-up protocol.
Eligibility| Ages Eligible for Study: | 3 Years to 18 Years |

Inclusion Criteria:
- Enrolled in and completed the baseline evaluation in NCT01263600
- 3 to <18 years at time of randomization (day 0).
- Documented chronic HBV infection as evidenced by detection of HBsAg in serum for ≥ 24 weeks prior to randomization or positive HBsAg and negative anti-HBc IgM within 24 weeks of randomization.
- Presence of HBeAg in serum at the last screening visit within 6 weeks of randomization AND ≥24 weeks prior to randomization.
- Serum HBV DNA level >107 IU/mL on at least two occasions at least 12 weeks apart during the 52 weeks before randomization. The HBV DNA level from the last of the screening visits (within 6 weeks of randomization) must be used to meet this criterion.
- ALT ≤60 IU/l in males or ≤40 IU/l in females, measured on at least 2 occasions, at screening and at another time that is at least 12 weeks prior to the screening visit in the 52 weeks before randomization with no ALT values >60IU/l in males or >40 IU/l in females within the 48 weeks.
- Compensated liver disease, with normal total bilirubin (except if Gilbert's syndrome), direct bilirubin ≤0.5 mg/dL, INR ≤1.5, and serum albumin ≥3.5 g/dL.
- Creatinine clearance 90 ml/min.
- Absence of hepatocellular carcinoma on liver ultrasound in the past 48 weeks.
Exclusion criteria:
- Presence of infection at screening with HCV-RNA or anti-HCV, anti-HDV, or HIV.
- Presence of another cause of liver disease or HCC (serum alpha-fetoprotein >50ng /ml).
- Evidence of decompensated liver disease (Childs B-C).
- History or other evidence of a medical condition associated with chronic liver disease (e.g., hemochromatosis, autoimmune hepatitis, alcoholic liver disease, toxin exposures).
- Females who are pregnant or breastfeeding.
- Adolescent females unwilling or unable to use an acceptable method of contraception if sexually active during the treatment period.
- Children currently breastfeeding while their mother is taking lamivudine, or those who were exposed to lamivudine for ≥24 weeks via maternal lamivudine treatment during pregnancy and/or while breastfeeding.
- Previous liver or other organ transplantation including engrafted bone marrow transplant.
- Hematological abnormalities during the screening period that contraindicate full dosing with study drugs, e.g absolute neutrophil count < 1.5 x 109 cells/L or platelet count < 120 x 109 cells/L.
- Known allergy to study drugs; peginterferon alfa-2a or entecavir.
- Treatment with systemic acyclovir or famciclovir within the previous 6 months.
- Need for ongoing use of any antivirals with activity against HBV during the course of the study or history of receiving treatment for HBV.
- Any use of illegal drugs OR use of alcoholic beverages which in the opinion of a study physician is sufficient to prevent adequate compliance with study procedures or increase the risk of pancreatitis or hepatotoxicity.
- History of immunologically mediated disease (e.g. inflammatory bowel disease, idiopathic thrombocytopenic purpura, lupus erythematosus, autoimmune haemolytic anemia, scleroderma, severe psoriasis, rheumatoid arthritis).
- History or other evidence of bleeding from esophageal varices or consistent with decompensated liver disease.
- History or other evidence of chronic pulmonary disease associated with functional limitation.
- History of significant cardiovascular diseases.
- History of a severe seizure disorder or current anticonvulsant use.
- History or other evidence of severe retinopathy.
- History of thyroid disease poorly controlled on prescribed medications. Participants with elevated thyroid stimulating hormone concentrations with elevation of antibodies to thyroid peroxidase and any clinical manifestations of thyroid disease are excluded.
- Concomitant use or use during ≤ 6 months prior to the first dose of study drug of anti-neoplastic, immunosuppressive, nephrotoxic or hepatotoxic medication, methadone, theophylline or medications that may affect renal excretion or hepatic metabolism are not permitted.
- Concomitant use of complementary or alternative medications purported to have antiviral activity.
- During the treatment phase of the study, a participant may not be co-enrolled in another clinical trial where an investigational drug is administered.
- Any other condition or situation that in the opinion of a study physician would make the participant unsuitable for enrollment or could interfere with the participant participating in and completing the study.
