About this study

Official title: A Phase I, Open Label, Parallel Group Trial To Evaluate Safety And Immunogenicity Of Three Nasal Immunisations Using A Fixed Dose-Level Of HIV gp140 V2 Loop Deleted Protein Adjuvanted With LTK63 Followed By Intramuscular Boosting With HIV gp140 V2 Loop Deleted Protein Adjuvanted With MF59 When Administered To Healthy Adults

The purpose of this study is to determine whether an HIV vaccine given as three nasal immunisations with a protein from HIV virus mixed with a toxoid adjuvant, followed by two intramuscular immunisations with the same protein mixed with a liquid adjuvant, causes untoward adverse reactions when administered to healthy adult volunteers. An initial evaluation of immune responses to the vaccine will also be undertaken.

The purpose of this study is to determine whether an HIV vaccine given as three nasal immunisations with a protein from HIV virus mixed with a toxoid adjuvant, followed by two intramuscular immunisations with the same protein mixed with a liquid adjuvant, causes untoward adverse reactions when administered to healthy adult volunteers. An initial evaluation of immune responses to the vaccine will also be undertaken by measuring gp140- and LTK63-specific IgG and IgA in cervical secretions, vaginal secretions, serum and nasal wash. IFNg secretion of T cells in response to gp140 peptide stimulation will be undertaken along with neutralising assays.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Human Immunodeficiency Virus glycoprotein 140 (vaccine), HIV glycoprotein 140 + Labile Toxin mutant LTK63 adjuvant and Labile Toxin mutant LTK63 adjuvant in people with HIV Infections, 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 4 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: stopped early, as of the sponsor's last update on 15 Apr 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 determine the frequency of vaccine-related local and systemic adverse events after nasal immunisation up to week 32 (time frame: 32 weeks). 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 15 Apr 2008.
