About this study

Official title: A Phase I Trial of the Safety and Immunogenicity of an Adjuvated TB Subunit Vaccine (Ag85B-ESAT6 + LTK63) Administered at 0 and 2 Months

The purpose of this study is to determine whether a subunit tuberculosis vaccine given as two nasal immunizations composed of a hybrid protein antigen from M. tuberculosis virus mixed with a toxoid adjuvant, causes untoward adverse reactions when administered to healthy adult volunteers. Both subjects who have not received Bacillus Calmette-Guerin (BCG) and subjects who have already received BCG will be enrolled. An initial evaluation of immune responses to the vaccine will also be undertaken.

The purpose of this study is to determine whether a subunit tuberculosis vaccine given as two nasal immunizations composed of a hybrid protein antigen from M. tuberculosis virus mixed with a toxoid adjuvant, causes untoward adverse reactions when administered to healthy adult volunteers. Both subjects who have not received BCG and subjects who have already received BCG will be enrolled. An initial evaluation of immune responses to the vaccine will also be undertaken using flow cytometry to enumerate antigen specific IFNg containing T cells; ELISPOT to determine IFNg secreting antigen specific T cells; serology and nasal wash antibody.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Ag85B-ESAT6 fusion protein H1 in people with Tuberculosis, run by St George's, University of London at 1 site in United Kingdom.

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 10 inclusion and 19 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: stopped early, as of the sponsor's last update on 3 Nov 2008. 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 United Kingdom. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

The study was stopped early (reason given: Safety Issues). 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?

To evaluate the safety profile (medical examinations, adverse events and laboratory safety tests) of a nasal TB subunit vaccine with and without adjuvant given as two doses with 2 months interval. (time frame: 8 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 3 Nov 2008.
