Clinical Trials associated with A244 rgp120/HIV-1(NIAID)A Phase III Trial to Determine the Efficacy of AIDSVAX B/E Vaccine in Intravenous Drug Users in Bangkok, Thailand
The purpose of this study is to determine if the vaccine, AIDSVAX B/E, will protect intravenous drug users from becoming infected with HIV.
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
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.
Phase I/II Trial to Evaluate the Safety and Immunogenicity of AIDSVAX B/B and B/E Vaccines in the United States
The purpose of this study is to see if it is safe and effective to give AIDSVAX B/B or AIDSVAX B/E, two potential HIV vaccines, to HIV-negative volunteers.
