About this study

To evaluate the safety and immunogenicity of high-titered ALVAC-HIV MN120TMG (vCP205) given sequentially or simultaneously with rgp120/HIV-1SF2 in MF59 adjuvant emulsion in HIV-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. vCP205 expresses proteins from two strains of HIV (MN and LAI). rgp120/HIV-1SF2 expresses proteins from a different strain of HIV. This study will help to show how the immune system responds to proteins from more than one strain of virus.

ALVAC-HIV vCP205 is a second-generation candidate vaccine that can be used to induce a humoral and cellular response against several antigens. vCP205 expresses proteins from two strains of HIV (MN and LAI). rgp120/HIV-1SF2 expresses proteins from a different strain of HIV. This study will help to show how the immune system responds to proteins from more than one strain of virus.

Six groups of 25 volunteers each are randomized to receive simultaneous or sequential doses of ALVAC-HIV vCP205 and SF2 rgp120 or control vaccines (ALVAC-RG rabies glycoprotein vCP65 or BIOCINE Placebo Vaccine 2). In each group, 21 volunteers receive vaccine and 4 receive control vaccines. Volunteers are stratified by lower or higher risk sexual behavior. Immunizations are given to three groups at months 0, 1, 3, 6, 9, and 12, and to the other three groups at months 0, 1, 6, 9, and 12. Volunteers are followed for 24 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 12 inclusion and 29 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 NCT00000847, which also lists 7 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.
