About this study
To expand the available data regarding the safety and immunogenicity of 2 HIV-1 vaccine strategies: canarypox vector vCP205, or vCP205 with SF-2 rgp120. [AS PER AMENDMENT 7/2/98: To obtain immunogenicity and safety data on gp120 subunits that may induce enhanced neutralizing antibody response to primary isolates of HIV-1 in the context of previous immunization with a canarypox vector expressing HIV antigens (vCP205). To evaluate cytotoxic T lymphocyte responses at 1 and 2 years after initial vaccination with vCP205 plus rgp120 SF-2 or vCP205 alone.] In previous ALVAC vCP205/SF-2 rgp 120 studies, patients have developed antibodies that neutralize homologous laboratory strains; over 50% of patients have developed CD8+ cytotoxic T-lymphocyte responses to HIV env and gag epitopes at some point in the study. This Phase II study seeks to confirm these results among persons at lower or higher risk for HIV infection with a new lot of ALVAC vCP205, at a dose that is suitable for potential large-scale trials. [AS PER AMENDMENT 7/2/98: Addition of AIDSVAX B/B or AIDSVAX B/E boosts starting at least 12 months after receiving rgp120 or ALVAC vaccines may induce enhanced neutralizing antibody response as deemed from prior studies and thus is planned as "follow-up" therapy.]

This Phase II study seeks to confirm these results among persons at lower or higher risk for HIV infection with a new lot of ALVAC vCP205, at a dose that is suitable for potential large-scale trials.

Volunteers are recruited and screened; those who are enrolled are then stratified by their risk status into 2 groups: individuals having lower-risk behavior for HIV and individuals having higher-risk behavior for HIV. Volunteers are then randomly assigned to arm A, B, or C and receive immunizations at months 0, 1, 3, and 6 as follows:
Group A- ALVAC vCP205 plus SF-2 rgp120 in MF59. Group B- ALVAC vCP205 plus saline placebo. Group C- Placebo-ALVAC plus saline placebo. [AS PER AMENDMENT 7/2/98: Beginning 12-18 months after initial vaccination, then 2, 6, and 12 months later, 10 volunteers from group A receive saline placebo, while 50 volunteers each from groups B and C are rerandomized within their respective groups, and are treated as follows.
Group B (subgroup 1) - AIDSVAX B/B. Group B (subgroup 2) - AIDSVAX B/E. Group B (subgroup 3) - alum placebo. Group C (subgroup 1) - AIDSVAX B/B. Group C (subgroup 2) - AIDSVAX B/E. Group C (subgroup 3) - alum placebo.] Volunteers are followed for 2 years and are tested for humoral immune response to HIV-1. Neutralizing activity to HIV-1 is performed on a subset of volunteers monitored for CTL response. [AS PER AMENDMENT 7/2/98: Volunteers receiving AIDSVAX B/B and AIDSVAX B/E will additionally be studied for formation of various neutralizing antibodies and parameters of cellular immunity.] [AS PER AMENDMENT 4/30/99: Because the subunit boosts that were added in version 3.0 are not available, the subunit boost portion of version 3.0 is cancelled.]

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing MN rgp120/HIV-1 and GNE8 rgp120/HIV-1, MN rgp120/HIV-1 and A244 rgp120/HIV-1 and ALVAC-HIV MN120TMG (vCP205) in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 18 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 4 inclusion and 26 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 18 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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 NCT00000871, which also lists 5 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.
