NCT01940341

Brief Summary

The primary objective of this study is to compare the efficacy, safety, and tolerability of tenofovir alafenamide (TAF) versus tenofovir disoproxil fumarate (TDF) in treatment-naive and treatment-experienced adults with hepatitis B e antigen (HBeAg)-negative chronic hepatitis B virus (HBV) infection.

Outcome Measures

Primary Outcomes (1)

  • Percentage of Participants With Hepatitis B Virus (HBV) DNA < 29 IU/mL

    The primary efficacy endpoint was determined by the achievement of HBV DNA \< 29 IU/mL at Week 48.

    Week 48

Secondary Outcomes (3)

  • Percent Change From Baseline in Hip Bone Mineral Density (BMD) at Week 48

    Baseline, Week 48

  • Percent Change From Baseline in Spine BMD at Week 48

    Baseline, Week 48

  • Change From Baseline in Serum Creatinine at Week 48

    Baseline, Week 48

Other Outcomes (1)

  • Percentage of Participants With Treatment-emergent Proteinuria by Urinalysis (Dipstick) Through Week 48

    Up to 48 weeks

Study Arms (3)

TAF 25 mg

EXPERIMENTAL

TAF + TDF placebo for 96 weeks (per amendment 1 \& 2) or 144 weeks (per amendment 3).

Drug: TAFDrug: TDF Placebo

TDF 300 mg

ACTIVE COMPARATOR

TDF + TAF placebo for 96 weeks (per amendment 1 \& 2) or 144 weeks (per amendment 3).

Drug: TDFDrug: TAF Placebo

Open-label TAF

EXPERIMENTAL

All participants who complete the double-blind period (96 weeks or 144 weeks) will be eligible to receive open-label TAF until Week 384 of the study. After the end of study treatment, participants can either switch to commercially available anti-HBV treatments in their country or will be followed every 4 weeks, for up to 24 weeks off treatment (treatment-free follow-up (TFFU)) for safety assessment.

  • 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 Baseline.
  • Adequate renal function.
  • Normal electrocardiogram (ECG).

You may not qualify if:

  • 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, human immunodeficiency virus (HIV), or hepatitis D virus.
  • Evidence of hepatocellular carcinoma.

  • Abnormal hematological and biochemical parameters, including aspartate aminotransferase (AST) \> 10 x ULN
  • Received solid organ or bone marrow transplant.
  • History of malignancy within the past 5 years, with the exception of specific cancers that are cured by surgical resection; individuals under evaluation for possible malignancy are not eligible.
  • Currently receiving therapy with immunomodulators (eg, corticosteroids), investigational agents, nephrotoxic agents, or agents capable of modifying renal excretion.
  • 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.
