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
EXPERIMENTALTAF + TDF placebo for 96 weeks (per amendment 1 \& 2) or 144 weeks (per amendment 3).
TDF 300 mg
ACTIVE COMPARATORTDF + TAF placebo for 96 weeks (per amendment 1 \& 2) or 144 weeks (per amendment 3).
Open-label TAF
EXPERIMENTALAll 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.
Interventions
25 mg tablet administered orally once daily
Eligibility Criteria
You may qualify if:
- 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 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.
- Any history of, or current evidence of, clinical hepatic decompensation.
- 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.
