Detailed Description:
This study GS-US-320-0108 is an international study planned to enroll participants in global countries, including China. However, due to the review timeline difference in China, full enrollment was reached in the main study before China was able to participate. Therefore, details for the China cohorts were registered separately (NCT02836236) on ClinicalTrials.gov as these cohorts will not be part of the main study analysis.
  Eligibility

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Ability to understand and sign a written informed consent form, which must be obtained prior to initiation of study procedures
  • Adult males and non-pregnant, non-lactating females
  • Documented evidence of chronic HBV infection
  • Hepatitis e antigen (HBeAg)-negative, chronic hepatitis B with all of the following:

    • HBeAg-negative and hepatitis B e antibody (HBeAb) positive at screening
    • Screening HBV DNA ≥ 2 x 10^4 IU/mL
    • Screening serum alanine aminotransferase (ALT) level > 60 U/L (males) or > 38 U/L (females) and ≤ 10 x the upper limit of the normal range (ULN)
  • Treatment-naive participants (defined as < 12 weeks of oral antiviral treatment with any nucleoside or nucleotide analogue), OR treatment-experienced participants (defined as participants meeting all entry criteria [including HBV DNA and serum ALT criteria] and with ≥ 12 weeks of previous treatment with any nucleoside or nucleotide analogue)
  • Previous treatment with interferon (pegylated or non pegylated) must have ended at least 6 months prior to the baseline visit.
  • Adequate renal function
  • Normal ECG

Exclusion Criteria:

  • Females who are breastfeeding
  • Males and females of reproductive potential who are unwilling to use an "effective", protocol-specified method(s) of contraception during the study
  • Co-infection with hepatitis C virus, HIV, or hepatitis D virus
  • Evidence of hepatocellular carcinoma

  • Individuals receiving ongoing therapy with drugs not to be used with tenofovir alafenamide or tenofovir disoproxil fumarate or individuals with a known hypersensitivity to study drugs, metabolites, or formulation excipients
  • Current alcohol or substance abuse judged by the investigator to potentially interfere with participant compliance
  • Any other clinical condition or prior therapy that, in the opinion of the Investigator, would make the participant unsuitable for the study or unable to comply with dosing requirements
