About this study
To determine the safety of vaccinia-derived HIV-1 recombinant envelope glycoprotein (gp160) in human volunteers; to evaluate the immunogenicity of this preparation in human volunteers. Although recent advances have been made in antiviral therapy against AIDS, there is currently no cure for AIDS. It is likely that ultimate control of the disease depends on the development of safe and effective vaccines against HIV.
Read the detailed description
Although recent advances have been made in antiviral therapy against AIDS, there is currently no cure for AIDS. It is likely that ultimate control of the disease depends on the development of safe and effective vaccines against HIV.
Healthy, adult volunteers without identifiable high-risk behavior for HIV-1 infection are vaccinated. In phase 1, at each participating unit, four volunteers receive a dose of gp160 (12.5 mcg); two volunteers receive placebo. Volunteers are monitored 1 month before proceeding to the second phase. In phase 2, four volunteers receive gp160 (50 mcg); two volunteers receive placebo. Primary immunization and two booster immunizations at day 30 and day 180 are done in an outpatient setting. Volunteers are closely monitored for the first 2 weeks postimmunization (primary and boosters), and extensively followed for a minimum of 2 years. Volunteers may be offered an additional boost of the same preparation at 18 months. Per 07/28/92 amendment, 18 volunteers will receive 200 mcg gp160 in an unblinded study. Volunteers in phase 2 who received four doses of 50 mcg gp160 receive an additional boost of 200 mcg gp160 at 18-19 months post initial vaccination. Per 05/13/94 amendment, volunteers in phase 2 who received the additional 200 mcg boost receive another 200 mcg boost 18-24 months after the last injection (St. Louis University site only).

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing gp160 Vaccine (Immuno-AG) 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 3 inclusion and 19 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 NCT00000968, 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.
