HIV InfectionsPhase 1NCT00001096
A Phase I, Multicenter, Randomized, Double-Blind, Placebo-Controlled Trial to Evaluate the Safety and Immunogenicity of HIV-1 MN rsgp120 and Bivalent AIDSVAX B/E (HIV-1 MN rgp120/A244 rgp120) in Combination With QS-21 With or Without Alum in Healthy HIV-1 Uninfected Adults
A Phase 1 study testing MN rgp120/HIV-1 and A244 rgp120/HIV-1, QS-21 and rgp120/HIV-1MN in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 4 sites in United States.
Trial summary
To assess the safety and immune response to two experimental vaccines when formulated with QS-21 or QS-21 plus alum. To determine whether the new preparation of QS-21 in polysorbate 80 is less reactogenic than the QS-21 formulation used in AVEG Protocols 016, 016A, and 016B. Read more about this study

About this study
To assess the safety and immune response to two experimental vaccines when formulated with QS-21 or QS-21 plus alum. To determine whether the new preparation of QS-21 in polysorbate 80 is less reactogenic than the QS-21 formulation used in AVEG Protocols 016, 016A, and 016B. To examine whether QS-21 is immunologically equivalent to that used in 16B. To determine if QS-21, when given with low doses of antigen, induces measurable HIV-1-specific CTL activity. To evaluate if the QS-21 dose-sparing effect extends to an antigen dose of 0.5 micrograms. To determine if the bivalent vaccine gives responses equivalent to the monovalent product or if a broadening of the HIV-1-specific binding and neutralizing antibody responses occurs.
An effective vaccine to prevent HIV-1 infection may need to generate diverse and multifaceted immunologic responses. Required parts of the immune response may include: humoral antibodies, which broadly neutralize non-syncytium-inducing strains of HIV-1; T cell help provided by both CD4 and CD8 positive subsets; and a class I-restricted cytotoxic lymphocyte response. Other effector responses, such as the generation of antibody-dependent cellular cytotoxicity, cytokines, chemokines, or other antiviral factors may also be critical in mounting protective immunity. Given the lack of a surrogate immunologic marker, the most practical approach for possible efficacy trials would be to evaluate a candidate vaccine that elicits as many of these responses as possible.

Volunteers in each of 5 groups receive vaccine or placebo by intramuscular injection at Months 0, 1, and 6. All patients receive one of two doses of QS-21 along with vaccine or placebo and some groups receive alum as follows:
Group 1: low-dose MN rsgp120/HIV-1 plus QS-21 (13 volunteers). Group 2: high-dose MN rsgp120/HIV-1 plus QS-21 (13 volunteers). Group 3: AIDSVAX B/E (injection contains each of the two vaccine components, HIV-1 MN rgp120 and A244 rgp120/HIV-1) plus QS-21 plus alum (13 volunteers).
Group 4: high-dose MN rgp120/HIV-1 plus QS-21 plus alum (13 volunteers). Group 5: placebo plus QS-21 (8 volunteers). Volunteers will be closely monitored after each immunization and followed for a minimum of 12 months after the initial immunization.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing MN rgp120/HIV-1 and A244 rgp120/HIV-1, QS-21 and rgp120/HIV-1MN in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 4 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 27 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 4 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 NCT00001096, which also lists 1 linked publication.
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.
