Chronic Hepatitis B
About this trial
This is an interventional treatment trial for Chronic Hepatitis B focused on measuring Chronic hepatitis B, pediatrics, antiviral treatment, telbivudine
Eligibility Criteria
Key Inclusion Criteria:
- Clinical history compatible with compensated chronic hepatitis B
Documented compensated chronic hepatitis B defined by the following:
- Positive serum HBsAg at screening and at least one other documentation of HBsAg positive at least 6 months prior to screening
- For HBeAg positive patients at screening, significant biologic and/or histologic signs of disease activity following EASL guidelines recommendations for CHB pediatric patients (serum HBV DNA level ≥ 5 log10 copies/mL (or 20 000 IU/mL) (COBAS Taqman®) at screening ; serum ALT ≥ 1.5×ULN and < 10×ULN (pediatric ULN) for two times during the screening period or within 6 months prior to screening
- For HBeAg negative patients at screening, significant biologic and/or histologic signs of disease activity following EASL guidelines recommendations for CHB pediatric patients (serum HBV DNA level ≥ 4 log10 copies/mL (or 2 000 IU/mL) (COBAS Taqman®) at screening) ; serum ALT ≥ 1.0 ×ULN and < 10×ULN (pediatric ULN) for two times during the screening period or within 12 months prior to screening)
Key Exclusion Criteria:
- Patients with acute or chronic infection of HCV, HDV, HIV, or with acute infection of HAV, HEV, CMV, EBV, or HSV.
- Patient has received treatment of interferon or any other immunomodulatory agents within the last 12 months prior to screening or any nucleoside or nucleotide drugs or other anti-CHB treatment (approved or investigational) at any time before screening
- Patient has a medical condition that requires frequent use of systemic acyclovir or famciclovir, systemic corticosteroids, potentially hepatotoxic drugs or nephrotoxic drugs or chemotherapy
- Patient has one or more additional known primary or secondary causes of liver disease, other than CHB; has a decompensated liver disease ; is a Liver transplant recipient or organ or bone marrow transplant recipient.
- History of any other acute or chronic medical condition (that in the opinion of the investigator would make the patient unsuitable for inclusion into the study.
- Patient has a history of myopathy, myositis, persistent muscle weakness or persistent high serum CK levels (≥7×ULN), any muscular disease
- Patient receiving any drugs potentially associated with myopathy within 3 months prior to screening
- Any other clinical significant disease, condition or abnormality, unrelated to their HBV infection at screening, as assessed by the investigator
