About this study
Part A: To evaluate the safety and immunogenicity of ALVAC vCP125 HIV-1 gp160 MN live canarypox recombinant vaccine (ALVAC gp160 MN) versus a recombinant canarypox expressing the rabies glycoprotein (ALVAC rabies glycoprotein) as a control in healthy, HIV-1 uninfected adult volunteers.
Part B: To evaluate the schedule of two immunizations with ALVAC gp160 MN for optimal immunogenicity.
Read more
Amendment: 12/22/93: To determine whether ALVAC gp160 MN in combination with SF-2 rgp120 subunit protein is capable of generating humoral and cellular immune responses of greater intensity and longer duration than either vaccine administered alone.
A canarypox-vectored vaccine (ALVAC) that expresses the gp160 antigen of the HIV-1 MN strain might satisfy many criteria for an affordable HIV vaccine. Per 12/22/93 amendment: Cellular responses have been augmented by the combination of two recombinant vaccines, especially in vaccinia naive individuals.

A canarypox-vectored vaccine (ALVAC) that expresses the gp160 antigen of the HIV-1 MN strain might satisfy many criteria for an affordable HIV vaccine. Per 12/22/93 amendment: Cellular responses have been augmented by the combination of two recombinant vaccines, especially in vaccinia naive individuals.
In Part A, 28 healthy volunteers (15 vaccinia-immune and 13 vaccinia-naive) are randomized to receive intramuscular injections of ALVAC gp160 MN at a dose of 1 million TCID50 or ALVAC rabies glycoprotein as a control at months 0 and 2. In Part B, 90 healthy volunteers (60 vaccinia immune and 30 vaccinia naive) are randomized to receive ALVAC gp160 MN at a dose of 10 million TCID50 or ALVAC rabies glycoprotein control, on an immunization schedule of either month 0 and 1 or 0 and 2. For Part B, half of the patients receiving ALVAC gp160 MN, as well as approximately half of those receiving control vaccine, will receive booster immunizations with SF-2 rgp120 subunit protein, if available, at months 9 and 12; the other half will receive booster immunizations with the same preparation as they received for their first two immunizations. In Part A, all control volunteers except one within each control group receive SF-2 rgp120 subunit protein at months 9 and 12. An additional group of 10 volunteers will receive four injections of SF-2 rgp120 subunit protein at months 0, 1, 6 and 12. Part B will begin whenever the higher dose of ALVAC gp160 MN becomes available (at least 4 weeks after initiation of Part A). Volunteers are followed for at least 18 months. Per 06/10/94 addendum, volunteers will be contacted once or twice per year for at least 5 years to check on health status.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing ALVAC-HIV gp160MN (vCP125), 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 1 site 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 11 inclusion and 25 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 1 site 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 NCT00000813, which also lists 4 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.
