About this study

Official title: Determinants of Sustained Virological Response After Discontinuation of Long-term Nucleoside Analogue Therapy in Chronic Hepatitis B Patients

Evaluation of the rate of sustained virological response among HBeAg-negativechronic hepatitis B patients who discontinue long-term NA therapy.

During this study participants will cease their prescribed medications, this will occur with immediate effect once enrolled into the study. The duration of cessation will be indefinite, unless clinically indicated for NA therapy re-start. Participants will be monitored as per protocol following cessation, monitoring will be by clinic visit and through blood test to monitor virological response. Clinical visits will be at the intervals of week 2, week, 4, week 8, week 12, week 18, following this they will be every 3 months out to 2 years when the participant will have completed the trial. Once the participant has completed the trial they will not commence again, the aim is for an indefinite cessation of NA therapy.

What is being measured

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

  1. The primary aim of this study is to evaluate the rate of sustained virological response among HBeAg-negative chronic hepatitis B patients who discontinue long-term NA therapy. The outcome is to be assessed by serum assay.

    Measured: Patients will be closely followed for 2 years prospectively, at the following time points; 2 weeks post cessation, 4 weeks, 8 weeks, 12 weeks, 18 weeks, then from 6 months the visits will be 3 monthly out to two years, to observe for virological changes.

Secondary outcomes (1)
  1. To identify novel immunological determinants of SVR, the assessment will be by serum assay.

    Measured: Patients will be closely followed for 2 years prospectively, at the following time points; 2 weeks post cessation, 4 weeks, 8 weeks, 12 weeks, 18 weeks, then from 6 months the visits will be 3 monthly out to two years.

Questions about this trial

What is this clinical trial studying?

A study testing Nucleoside Analogue therapy in people with Chronic Hepatitis B., run by St Vincent's Hospital Melbourne at 1 site in Australia.

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 12 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 14 Oct 2016. 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 Australia. 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 Gareth Burns, MD (+61309231 3581, gareth.burns@svha.org.au), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The primary aim of this study is to evaluate the rate of sustained virological response among HBeAg-negative chronic hepatitis B patients who discontinue long-term NA therapy. The outcome is to be assessed by serum assay. (time frame: Patients will be closely followed for 2 years prospectively, at the following time points; 2 weeks post cessation, 4 weeks, 8 weeks, 12 weeks, 18 weeks, then from 6 months the visits will be 3 monthly out to two years, to observe for virological changes.). 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 NCT02581033, which also lists 3 linked publications.

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 14 Oct 2016; AzTrials last refreshed its copy on 8 Nov 2026.
