About this study

Official title: Development of Read-outs to Detect and Characterise the Early and Adaptive Immune Responses in Healthy, Hepatitis B Virus Naive Adults Vaccinated With the Hepatitis B Surface Antigen in Combination With a GSK Biologicals' Adjuvant System

This study aims to develop innovative immunological read-outs and new technologies in order to further characterise the early immune response and its kinetics as well as the adaptive immune responses to adjuvanted vaccines.

This study will also evaluate the reactogenicity in healthy, hepatitis B virus naive adults vaccinated with the hepatitis B surface antigen in combination with a GSK Biologicals' Adjuvant System.

Read the detailed description

This study will be conducted in 2 steps with 2 study groups in each step. The entire study period for Step 1 is from Day -30 to Day 210 (240 days) The entire study period for Step 2 is from Day 0 to Day 180 for Group C and from Day 0 to Day 330 for Group D.

Subjects will be blinded up to Day 60 in Step 1 and will be unblinded at the end of their Day 60 visit. Step 2 will be conducted in an open-label manner.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Adjuvanted Hepatitis B surface antigen (HBsAg) candidate vaccine GSK2231392A. and EngerixTM-B in people with Hepatitis B, run by GlaxoSmithKline 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 11 inclusion and 33 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: finished, as of the sponsor's last update on 4 Jan 2019. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 4 Jan 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Concentrations of Cytokines and Chemokines - Step 1 (time frame: At Day -30 prior to placebo administration). The study lists 40 primary outcomes in all. 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 NCT01777295, 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 4 Jan 2019.
