About this study

Official title: Characterization of Molecular Signature Associated With T-cell Dysfunction Observed During Chronic HBV Infection

Chronic hepatitis B (CHB) infection remains an important public health with more than 240 million people chronically infected despite the existence of an effective vaccine. Cirrhosis and hepatocellular carcinoma (HCC) are major complications of CHB infection and are responsible for more than 600,000 deaths each year. These complications are strongly related to the function of the immune system. Indeed, the persistence of HBV and the progression of liver disease are mainly due to the development of an ineffective immune response to HBV. Therefore, the clinical outcome depends on the complex interaction between HBV replication and adaptive immune responses.

The ultimate goal of antiviral treatments is the elimination of HBsAgHBs and the appearance of anti-HBs antibodies without detectable PCR replication. Current treatments are effective at lowering viral DNA levels, but they are not able to permanently eliminate chronic HBV infection, due to the persistence of cDNA in the nucleus of infected hepatocytes. This therapeutic goal is rarely achieved and new therapeutic approaches are needed. In this sense, Immunotherapy represents a very promising new therapeutic approach that could lead to the cure of chronic HBV infection. Indeed, HBV infection is characterized by a progressive depletion of T lymphocytes which results in a progressive loss of function, associated with a sustained positive regulation of inhibitory control molecules.

Thus, the objective of this study is to define the immune signature and the main control pathways associated with T-cell depletion in patients chronically infected with HBV, by analyzing immune cells isolated from these patients at phenotypic , transcriptional and functional levels

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Phenotypic analyze of exhausted T-cells (CD4 and CD8)

    a blood sample will be analysed to see the impact of chronic HBV infection on T cell dysfunction.

    Measured: Day 0

  2. Transcriptional analyze of exhausted T-cells (CD4 and CD8)

    a blood sample will be analysed to see the impact of chronic HBV infection on T cell dysfunction.

    Measured: Day 0

Secondary outcomes (1)
  1. Response to functional T-cells stimulation tests

    This response will be evaluated by functional T cell stimulation tests in the presence or absence of immunomodulatory molecules targeting immune checkpoint receptors such as PD1, but also Tim-3, LAG3 or others.

    Measured: Day 0

Questions about this trial

What is this clinical trial studying?

A study testing Additional blood sampling (100 ml) in people with Chronic Hepatitis B Virus, run by University Hospital, Strasbourg, France at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 16 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 29 Oct 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact François HABERSETZER, MD (3 69 55 10 09 ext. 0033, francois.habersetzer@chru-strasbourg.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phenotypic analyze of exhausted T-cells (CD4 and CD8) (time frame: Day 0). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Oct 2021; AzTrials last refreshed its copy on 27 Oct 2026.
