HIV, HBV
About this trial
This is an interventional treatment trial for HIV focused on measuring HIV, HBV, Coinfection
Eligibility Criteria
Key Inclusion Criteria:
Both Cohorts 1 and 2:
- The ability to understand and sign a written informed consent form, which must be obtained prior to initiation of study procedures
- HIV/HBV co-infected adult males and non-pregnant and non-lactating females
No evidence of hepatocellular carcinoma (HCC) or clinical or imaging evidence of cirrhosis (ascites, variceal bleeding, encephalopathy).
--- Subjects should have documentation of an abdominal ultrasound in the 12 months prior to screening, or an abdominal ultrasound at screening, demonstrating the absence of cirrhosis and HCC.
- Acute Hepatitis A virus (HAV) immunoglobulin M (IgM) negative
- Hepatitis C virus (HCV) Ab negative, or HCV Ab positive with negative HCV RNA
- Hepatitis D virus (HDV) Ab negative, or HDV Ab positive with negative HDV RNA
- Estimated glomerular filtration rate (eGFR) ≥ 50 mL/min according to the Cockcroft-Gault formula
- CD4+ count of > 200 cells/μL
Chronic HBV infection as defined by
- HBsAg positive for ≥ 6 months Or
- HBsAg positive at screening and either hepatitis B e antigen (HBeAg) or HBV DNA positive ≥ 6 months Or
At screening: positive total hepatitis B core antibody (HBcAb) and negative immunoglobulin M antibody to hepatitis B core antigen (HBcIgM) antibody, and
- HBsAg positive, or
- HBeAg positive, or
- HBV DNA positive
Cohort 1 (HIV and HBV treatment naive) only:
- No current or prior anti-HIV treatment, including antiretroviral medications received for prevention (PrEP), or post exposure prophylaxis (PEP)
- No current or prior anti-HBV treatment
- Plasma HIV-1 RNA level ≥ 500 copies/mL at screening
- Screening HBV DNA ≥ 3 log10 IU/mL and < 9 log10 IU/mL
Cohort 2 (HIV suppressed) only:
- Receiving current antiretroviral regimen for at least 4 consecutive months
- No current or prior regimen containing 3 active anti-HBV agents (i.e. cannot be on tenofovir alafenamide (TDF)/emtricitabine (FTC)/Entecavir or TDF/lamivudine(3TC)/Entecavir)
- Maintained plasma HIV-1 RNA < 50 copies/mL for 6 consecutive months prior to and at the time of the screening visit. Unconfirmed virologic evaluation of ≥ 50 copies/mL after previously reaching viral suppression (transient detectable viremia, or "blip") and prior to screening is acceptable
- Documented positive HIV antibody test
- Screening HBV DNA < 9 log10 IU/mL
Key Exclusion Criteria:
- Females who are breastfeeding
- Positive serum pregnancy test (female of childbearing potential)
- Have an implanted defibrillator or pacemaker
- Current alcohol or substance use
- A history of malignancy within the past 5 years (prior to screening) or ongoing malignancy other than cutaneous Kaposi's sarcoma (KS), basal cell carcinoma, or resected, non-invasive carcinoma.
- Received solid organ or bone marrow transplant
- Any history of, or current evidence of, clinical hepatic decompensation (e.g., ascites, encephalopathy or variceal hemorrhage).
- Significant bone disease (e.g., osteomalacia, chronic osteomyelitis, osteogenesis imperfecta, osteochondroses), or multiple bone fractures
- Active, serious infections (other than HIV-1 infection) requiring parenteral antibiotic or antifungal therapy within 30 days prior to Day 1
- Subjects on hemodialysis, other forms of renal replacement therapy, or on treatment for underlying kidney diseases (including prednisolone, and dexamethasone)
- Any other clinical condition or prior therapy that, in the opinion of the Investigator, would make the subject unsuitable for the study or unable to comply with the dosing requirements
- Investigational agents (unless approved by Gilead Sciences). Participation in any other clinical trial without prior approval from the sponsor is prohibited while participating in this trial
Note: Other protocol defined Inclusion/Exclusion criteria may apply.
