Trial summary

It is probable that a mucosal approach is necessary for a prophylactic HIV vaccine protecting against sexually transmitted infection. Mucosal immune responses have been almost non-existent in trials of HIV vaccine candidates in which the antigen was delivered systemically. Read more about this study

About this study

Official title: Phase I Study Evaluating the Systemic and Mucosal Safety and Immunogenicity of a Recombinant HIV-1 Gp 160 (MN/LAI) Administered by Transmucosal (Nasal or Vaginal) Routes, Alone or Formulated With DC-Chol, in HIV Negative Volunteers (ANRS VAC14)

It is probable that a mucosal approach is necessary for a prophylactic HIV vaccine protecting against sexually transmitted infection. Mucosal immune responses have been almost non-existent in trials of HIV vaccine candidates in which the antigen was delivered systemically. This study will test the safety and immune response of a recombinant HIV-1gp160 by nasal and mucosal routes alone or formulated with DC-Chol in healthy volunteers.

Read the detailed description

It's probable that a mucosal approach is necessary for prophylactic HIV vaccine protecting against sexually transmitted infection. Although mucosal immune responses have been almost non-existent in trials of HIV vaccine candidates in which the antigen was delivered systematically.

Several animal models have also demonstrated the importance or a mucosal IgA response for protection against viral infections. Mucosal S IgA are essential effectors having different mechanisms of action agglutination of pathogens, interaction with cellular receptor, transcytosis of immune complexes, intracellular clearance of virus.

Gp 160 induces the majority of neutralizing Abs activity in patients serum and the immunogenicity of gp 160 can be improved by using and adjuvant such as DC-chol because of its properties to increase the permeation of the nasal epithelium and to facilitate systemic delivery of the vaccine antigen.

Before beginning mucosal vaccine trial, we previously tested and validated procedures to collect and process secretion fluids on 6 HIV-1 infected women (K. Petitprez et al, 4th European mucosal immunology group meeting, Lyon France, 8-10 october 2004).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing HIV-1 gp 160 and DC-Chol in people with HIV Infections, run by French National Agency for Research on AIDS and Viral Hepatitis at 1 site in France.

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 5 inclusion and 1 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 11 Nov 2005. 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 France. 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. 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?

Systemic and mucosal safety evaluated by 3 independent physicians at week 0, 4, 6 and 48 and 2 days after each mucosal administration. 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 11 Nov 2005.
