About this study

To evaluate the safety and immunogenicity of ALVAC-HIV MN120TMG (vCP205) in comparison to ALVAC-RG rabies glycoprotein (vCP65) as a control when administered in HIV-1 negative volunteers.

ALVAC-HIV vCP205 is a second generation candidate vaccine that can be used to induce a humoral and cellular response against several antigens. This recombinant construct is based on the canarypox vector termed ALVAC and expresses gp120 of the HIV MN strain, plus the transmembrane portion of the LAI strain as well as gag and protease.

Volunteers are randomized to receive doses of ALVAC-HIV vCP205 or ALVAC-HIV vCP65 control or both according to varying schedules over 12 months (was 6 months, amended 11/17/95) with a 12 month follow up. [AS PER AMENDMENT 5/29/98: One additional follow-up visit is required at 30-36 months.]

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ALVAC-HIV MN120TMG (vCP205), ALVAC-RG Rabies Glycoprotein (vCP65) and rgp120/HIV-1 SF-2 in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 6 sites in United States.

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 6 inclusion and 28 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 Nov 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00001055, which also lists 10 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 Nov 2021.
