About this study
To determine the safety and immunogenicity of vaccinia-derived HIV-1 recombinant envelope glycoprotein (gp160) in asymptomatic HIV-infected adult volunteers. To compare safety and immunogenicity of two different schedules of gp160 administration. To examine the effects of gp160 and hepatitis B vaccine (Engerix-B) on various markers of viral load and on selected immune parameters.
Potentiation of a patient's immune response to HIV might possibly prolong the period of clinical latency and protect the patient indefinitely. Preliminary results from a study of Immuno-AG recombinant gp160 vaccine in healthy volunteers not infected with HIV suggest that the vaccine is safe and produces antibodies against the virus. Because another previous study failed to demonstrate a specific anti-HIV response in patients injected with a recombinant vaccinia virus containing HIV-1 genes, this study is also testing the immunotherapeutic role of other immunizations (such as hepatitis B vaccination) that would be expected to induce a nonspecific immune response in HIV-infected persons.

Fifty-five healthy HIV-positive volunteers are randomly assigned to one of the following treatment arms: six injections (arm I) or four injections (arm II) of HIV-1 gp160 vaccine, four injections of hepatitis B vaccine as a non-HIV viral vaccine control (arm III), or six placebo injections consisting of the adjuvant vehicle used for the gp160 vaccine (arm IV). Immunizations or placebo are given at 4-week intervals for 5 months. To maintain blinding, adjuvant vehicle placebo is administered on days 84 and 112 to those volunteers receiving four instead of six vaccine injections (arms II and III). Volunteers are followed at 4-month intervals for 2 years.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing gp160 Vaccine (Immuno-AG) and Hepatitis B Vaccine (Recombinant) in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 2 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 7 inclusion and 17 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 2 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 2 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 NCT00000633, 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 2 Nov 2021.
