Safety and Effectiveness of Anti-HIV Vaccines in HIV-Negative Adults
A Phase 1 study testing ALVAC(2)120(B,MN)GNP (vCP1452), gp160 MN/LAI-2 and ALVAC(1)120(B,MN)GNP (vCP1433) in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 6 sites in United States.
Trial summary
The purpose of this study is to find out whether three different anti-HIV vaccines are safe and whether they help prevent HIV infection. These vaccines are called vCP205, vCP1433, and vCP1452. Some patients also receive another anti-HIV vaccine, gp160. Read more about this study

About this study
Official title: A Phase I Trial to Compare the Safety and Immunogenicity of the Live Recombinant Canarypox ALVAC-HIV Vaccines, vCP205, vCP1433, and vCP1452, in HIV-1 Uninfected Adult Volunteers
The purpose of this study is to find out whether three different anti-HIV vaccines are safe and whether they help prevent HIV infection. These vaccines are called vCP205, vCP1433, and vCP1452. Some patients also receive another anti-HIV vaccine, gp160. The vaccines are made up of small pieces of HIV, which help the body learn to recognize and destroy HIV. You cannot get HIV from these vaccines.
There are two different ways a vaccine can protect the body from infection. First, a vaccine may help the immune system make antibodies, which are proteins that recognize invading viruses or bacteria. Second, a vaccine may help the body make immune cells that destroy infected cells. The second type of vaccine is more powerful against HIV. In this study, doctors will see whether vCP205, vCP1433, vCP1452, and gp160 are good vaccines by seeing whether they help the body make immune cells.
Read the detailed description
Previous studies in humans have shown that immunization with certain vaccine combinations (that is, ALVAC-HIV construct and an envelope subunit vaccine) can elicit CTL activity, antibody-dependent cellular toxicity (ADCC), neutralizing antibodies, and other antibody responses more often and at higher levels than either vaccine alone. This study examines improved vaccine candidates that can elicit broader, longer-lasting CTL activity in the majority of vaccine recipients.
Volunteers are randomized to one of four groups. Group I receives vCP205. Group II receives vCP1433. Group III receives vCP1452. Group IV receives an ALVAC rabies vaccine, as a control. Immunizations are administered at Months 0, 1, 3, and 6. At Months 3 and 6, patients in Groups I, II, and III also receive gp160 MN/LAI-2, the subunit boost vaccine. Group IV receives another placebo vaccine. Participants have regular clinic visits and blood is drawn to determine humoral and cellular immune responses to the vaccines. [AS PER AMENDMENT 10/23/98: A cell-mediated immunity substudy has been added at selected institutions following the fourth vaccination at 6 months; this study will assess the newer assays of CD8+ T cells and the kinetic response following immunization. The 6-month immunization may be rescheduled by up to 14 days to accommodate clinical, laboratory, or volunteer scheduling issues.] [AS PER AMENDMENT 6/17/99: Three study arms are added. Group V receives vCP1452 at Months 0,1,3, and 6. Group VI receives vCP205 at Months 0,1,3, and 6. Group VII receives placebo at Months 0,1,3, and 6. Patients in Groups V, VI, and VII do not receive the subunit boost, gp160 MN/LAI-2. Consenting volunteers enrolled in the three new groups at Johns Hopkins University undergo PET scanning as part of an ancillary study.]

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing ALVAC(2)120(B,MN)GNP (vCP1452), gp160 MN/LAI-2 and ALVAC(1)120(B,MN)GNP (vCP1433) 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 12 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 NCT00000904, which also lists 2 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.
