Who can join

Age: 16 and older, up to 70. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Patients must give written informed consent before any assessment is performed.
• Male or female, 16 to 70 years of age.
• Black/African American race and/or Hispanic/Latino ethnicity
• Documented compensated chronic hepatitis B defined by all of the following:
• Clinical history compatible with compensated chronic hepatitis B.
• Positive serum HBsAg at least 6 months prior to study entry
• HBeAg-positive or HBeAg-negative at the Screening visit.
• Detectable serum HBsAg at the Screening visit.
• Serum ALT level > or = 1.3 and <10x ULN at the Screening visit.
• Serum HBV DNA level > or = 5 log10 copies/mL as determined by the COBAS™ Amplicor HBV PCR assay at the central study laboratory
• Willing and able to comply with the study drug regimen and all other study requirements.

You may not qualify if…

• Subject is pregnant or breastfeeding. Women of childbearing potential must have a negative serum beta-human chorionic gonadotropin (β-HCG) at Screening.
• Subject is of reproductive potential (men and women) and unwilling to use double barrier method of contraception. It is required that double barrier method of contraception be used (i.e. condom with spermicide or diaphragm with spermicide) by subjects of reproductive potential (men and women) regardless of whether a hormonal agent is also used as a method of contraception.
• Subject is co-infected with hepatitis C virus (HCV), hepatitis D virus (HDV), or human immunodeficiency virus (HIV-1 or HIV-2). Patients will be tested for antibodies to HCV, HDV, and HIV at the Screening visit in assessments performed at the central laboratory.
• Subject previously received lamivudine, adefovir dipivoxil, entecavir, telbivudine or an investigational anti-HBV nucleoside or nucleotide analog at any time. Precluded therapies include, but are not limited to, the following: any previous exposure to lamivudine, adefovir or other PMEA analogs (tenofovir, MCC-478), lobucavir, entecavir, emtricitabine (FTC), L-FMAU, L-Fd4C, or other investigational anti-HBV nucleosides/nucleotides.
• Subject has received interferon or other immunomodulatory treatment for HBV infection in the 12 months before Screening for this study. Precluded therapies include, but are not limited to, interferon agents (alpha-, beta- or gamma-interferons), thymosin, IL-12, or other putative systemic immunomodulators.
• Subject has a history of or clinical signs/symptoms of hepatic decompensation such as ascites, variceal bleeding, hepatic encephalopathy, or spontaneous bacterial peritonitis.
• Subject has a medical condition that requires prolonged or frequent use of systemic acyclovir or famciclovir (e.g., for recurrent herpes virus infections, etc). Prolonged use means episodic treatment with these agents for periods exceeding 10 days every 3 months, or chronic suppressive therapy.
• Subject has a history of hepatocellular carcinoma (HCC) or findings suggestive of possible HCC, such as suspicious foci on imaging studies or elevated serum alpha-fetoprotein (AFP) levels. In patients with such findings, HCC must be ruled-out prior to Screening for the present study.
• Subject has one or more additional known primary or secondary causes of liver disease, other than hepatitis B (e.g., alcoholism, autoimmune hepatitis, malignancy with hepatic involvement, hemochromatosis, alpha-1 antitrypsin deficiency, Wilson's Disease, other congenital or metabolic conditions affecting the liver, congestive heart failure or other severe cardiopulmonary disease, etc.). Gilbert's syndrome and Dubin-Johnson syndrome, two benign disorders associated with low-grade hyberbilirubinemia, will not exclude patients from participation in this trial.
• Subject has a history of clinical or laboratory evidence of pancreatitis or demonstrates a clinical or laboratory course consistent with pancreatitis within 12 weeks of study screening.
• Subject is currently abusing alcohol or illicit drugs, or has a history of alcohol abuse or illicit substance abuse within the preceding two years. For the purposes of the present study, alcohol abuse is arbitrarily defined as frequent consumption of alcoholic beverages with an average daily intake of more than 40g of ethanol or 3 beers or the equivalent. Patients currently on methadone maintenance treatment programs are NOT eligible for this study due to potential interference with the study evaluations.
• Subject has a medical condition that requires frequent or prolonged use of systemic corticosteroids (e.g., severe asthma, severe arthritis or autoimmune conditions, organ transplantation, adrenal insufficiency, etc).
• Subject has any other concurrent medical or social condition likely to preclude compliance with the schedule of evaluations in the protocol, or likely to confound the efficacy or safety observations of the study (e.g., concurrent malignancy; history of unstable angina or repeated myocardial infarction; uncontrolled asthma or diabetes; unstable thyroid disease or other significant hormonal condition; frequent or uncontrolled seizure disorder; severe psychiatric disorder requiring psychotropic medication; active tuberculosis, pneumonia, or other severe infection under current treatment; lives in a country other than that of the investigative site; or has other medical or social circumstances likely to interfere with the schedule of evaluations).
• A history of treated malignancy (other than hepatocellular carcinoma) is allowable if the subject's malignancy has been in complete remission, off chemotherapy and without additional surgical intervention, during the preceding 3 years.
• Subject has a history of myopathy, myositis, or persistent muscle weakness or peripheral neuropathy (polyneuropathy).
• Subject has a known history of allergy to nucleoside analogues.
• Subject is enrolled or plans to enroll in another clinical trial of an investigational agent while participating in this study.
• Subject has any of the following laboratory values at Screening:
• Absolute neutrophil count (ANC) <1500/mm3
• Hemoglobin <11.0 g/dL (men) or <10.0 g/dL (women)
• Platelet count <75,000/mm3
• ALT (SGPT) >10x ULN
• Serum creatinine >1.5x ULN
• Total bilirubin >2.0x mg/dL
• Prothrombin time >2.0 seconds above ULN
