About this study

Official title: Assessment of Hepatitis B Virus Intra-host Population and Host-specific Immune Marker Diversity With Next-generation Sequencing: From Chronic Infection to End-stage Liver Disease and Liver Cancer

In this project proposal, the investigators will investigate the genetic alterations of Hepatitis B Virus (HBV) strains circulating in Belgian patients who developed end stage liver disease. Additionally, the investigators will compare and link these data sets with three genetic factors involved in immune system response.

Read the detailed description

This project proposes to identify and characterize the genetic alterations associated with intra-host evolution of HBV from a chronically infection status to an end-stage liver disease status.

What is being measured

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

  1. genetic variants of Hepatitis B

    Virus variants will be identified by amino acid or nucleotide variations (insertions or deletions) in different Open Readind Frames (ORFs) of the HBV genome by using next-generation sequencing.

    Comparison of virus variants within one patient Comparison of virus variants between patients with end stage liver disease and patients with a chronic Hepatitis B infection.

    Determination of the viral load by quantitative Polymerase Chain Reaction (PCR).

    Measured: 6 months

Secondary outcomes (1)
  1. genetic variation in host-specific immune markers

    Amplification of HLA-A, HLA-B, HLA-C class I and HLA class II using PCR methods and next-generation sequencing

    Amplification of KIR genes: 2DS1, 2DS2, 2DS3, 2DS4, 2DS5, 3DS1 and 1D, 2DL1 2DL2, 2DL3, 2DL5 and 3DL1 using PCR methods and next-generation sequencing

    Amplification of SNPs in TNF alfa, TGF beta1 and IFN-R using PCR methods and next-generation sequencing

    Measured: at day of enrollment

Questions about this trial

What is this clinical trial studying?

An observational study of Hepatitis B and Hepatitis B, Chronic, run by Universitaire Ziekenhuizen KU Leuven at 1 site in Belgium.

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 7 inclusion and 2 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 28 May 2014. 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 Belgium. 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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

genetic variants of Hepatitis B (time frame: 6 months). 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 28 May 2014.
