Trial summary

The purpose of this study is to find out if a new investigational hepatitis B virus vaccine, HEPLISAV™, is safe and effective compared with Engerix-B® vaccine in subjects 11-55 years old. The primary hypothesis is that the seroprotective immune response of HEPLISAV™ is at least as good as that of Engerix-B®. Read more about this study

About this study

Official title: A Phase III Safety and Efficacy Study to Compare Immune Responses Following Injection With Either Two Doses of HEPLISAV™ or Three Doses of Engerix-B®

The purpose of this study is to find out if a new investigational hepatitis B virus vaccine, HEPLISAV™, is safe and effective compared with Engerix-B® vaccine in subjects 11-55 years old. The primary hypothesis is that the seroprotective immune response of HEPLISAV™ is at least as good as that of Engerix-B®.

Read the detailed description

This study will evaluate the safety and efficacy of two injections of HEPLISAV™, compared with three injections of a commercially available hepatitis B virus (HBV) vaccine, Engerix-B®, in subjects 11 to 55 years old. About 2,400 subjects will be included in the study. Once subjects are consented, screened, and randomized to treatment, all subjects will receive a total of three injections over a 24-week period, with a follow-up visit at 28 weeks. Subjects randomized to Engerix-B® will receive 3 injections of active vaccine, while subjects randomized to HEPLISAV™ will receive 2 injections of active vaccine plus 1 injection of placebo. Safety and tolerability will be evaluated by occurrence of adverse events, periodic laboratory tests, vital signs, and local/systemic reactogenicity.

Comparison: Subjects will receive treatment with either HEPLISAV™ or the comparator vaccine, Engerix-B®.

What is being measured

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

  1. Percentage of Subjects With Seroprotective Immune Response

    Percentage of subjects who have a seroprotective immune response (anti-HBsAg ≥ 10 milli-international unit (mIU)/mL) after the final active injection in each treatment group (Week 12 for HEPLISAV™ and Week 28 for Engerix-B®)

    Measured: Week 12 for HEPLISAV and Week 28 for Engerix-B

Secondary outcomes (1)
  1. Percentage of Participants With Local and Systemic Reactions to Injections

    Measured: Within 7 days post-injection for Post Injection Reactions

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Engerix-B in people with Hepatitis B, run by Dynavax Technologies Corporation at 18 sites in 2 countries.

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 2 inclusion and 8 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 20 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 18 sites in Canada, Germany. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 13 Feb 2018). 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?

Percentage of Subjects With Seroprotective Immune Response (time frame: Week 12 for HEPLISAV and Week 28 for Engerix-B). 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 20 Mar 2019.
