What the trial was testing
The trial enrolled 124 patients with hepatitis b. The study was sponsored by Gilead Sciences and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was initial testing (phase 2). Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.
What the results showed
Nearly 100% kept the virus suppressed after switching to tenofovir alafenamide.
The Lancet Gastroenterology & Hepatology · 2024 · NCT03180619
These findings — that after switching to tenofovir alafenamide in hepatitis B with kidney or liver impairment — were published in the The Lancet Gastroenterology & Hepatology and represent the headline result of the study.
Researchers tracked outcomes across 124 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with hepatitis b, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
Tenofovir alafenamide (Vemlidy) is FDA-approved and available now for chronic hepatitis B. It is the preferred form when kidney or bone health is a concern. Ask a liver specialist about switching from older tenofovir disoproxil if you have kidney or bone issues.
Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

The Role and Regulatory Mechanism of Germinal Center Immune Response in Hepatitis B Virus Infection
The purpose of this observational study is to investigate the structure and composition of germinal centers in individuals with chronic HBV infection. The primary questions it aims to address are: What are the phenotypes, functions, and complexity of B cell clones of the immune cells within the germinal centers of chronic HBV-infected individuals? Do chronic HBV-infected individuals have ectopic germinal centers in the liver? This will be studied by collecting peripheral blood and discarded liver, lymph node, and tonsil tissues from chronic HBV patients undergoing lymph node surgery, hepatectomy, and tonsillectomy.
Acceptability and Feasibility of Simultaneous Screening for Viral Hepatitis B, C and HIV Among Drug Users and Vulnerable Populations, in Non-conventional Structures "Outside the Walls" by Dual Screening Method RTDs and FibroScan®
The "Scanvir" concept aims to achieve barriers to HCV screening and treating of marginalized patients. The concept is applicable to other various populations and territories and should effectively improve HCV patient's health outcomes. The main objective of the SCANVIR project was to evaluate the feasibility, acceptability and reproducibility of a "test, treat and cure" strategy for PWIDs and vulnerable populations during dedicated days in addiction care centers.
