About this study

Official title: COntrolled Interruption of Nucleos(t)Ide Analogue Treatment in Chronic Hepatitis B Infections

In this study we will prospectively stop NA in both Caucasian and non-Caucasian patients matched for gender and age, to validate the observed host and viral parameters for future roll-out of this treatment strategy.

Read the detailed description

An estimated 290 million people worldwide are chronically infected with the Hepatitis B Virus (HBV). One fourth of untreated patients develop progressive liver damage and are at risk of liver-related death, which can be prevented by treatment with Nucleos(t)ide Analogues (NA). These drugs efficiently suppress viral replication, but seroclearance of the virus, defined as loss of Hepatitis B surface Antigen (HBsAg), is predicted to require an average of 36 to 52 years of treatment. Cessation of NA after long-term viral suppression in patients without HBV seroclearance might reduce costs and may even increase the chance of subsequent HBsAg loss. We have recently shown in a retrospective multicentric international study, that Caucasian ethnicity and off-treatment viral control are associated with HBsAg loss after NA cessation. In this study we will prospectively stop NA in both Caucasian and non-Caucasian patients matched for gender and age, to validate the observed host and viral parameters for future roll-out of this treatment strategy.

Questions about this trial

What is this clinical trial studying?

A study testing Cessation of ongoing treatment in people with Chronic Hepatitis B, run by University Hospital, Antwerp at 26 sites 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 6 inclusion and 6 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 24 Jun 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 26 sites 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?

Viral control (time frame: 72 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04779970, which also lists 1 linked publication.

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 24 Jun 2024.
