To evaluate the safety and immunogenicity of ALVAC-HIV MN120TMG (vCP205) in comparison to ALVAC-RG rabies glycoprotein (vCP65) as a control when administered in HIV-1 negative volunteers. ALVAC-HIV vCP205 is a second generation candidate vaccine that can be used to induce a humoral and cellular response against several antigens. This recombinant construct is based on the canarypox vector termed ALVAC and expresses gp120 of the HIV MN strain, plus the transmembrane portion of the LAI strain as well as gag and protease.
NCT00001031
To evaluate the safety and immunogenicity of SF-2 rgp120 vaccine in MF59 versus MN rgp120 vaccine in alum in volunteers who are seronegative for HIV-1. AS PER AMENDMENT 07/02/97: To determine the ability of immunization with MN rgp120/HIV-1 in combination with alum or SF-2 rgp120 in combination with MF59 to induce an HIV-1 envelope-specific delayed-type hypersensitivity (DTH) response in volunteers who receive rsgp120/MN skin testing. The amino acid sequence of HIV-1 gp120 can vary as much as 40 percent from isolate to isolate. Thus, the identification of an immunogen that can elicit broadly neutralizing antibodies to HIV-1 is a major challenge in AIDS vaccine development. Two candidate vaccines, recombinant envelope subunit proteins from the SF-2 and MN isolates of HIV-1, have shown immunogenicity and good tolerance in healthy immunocompetent adults. This study will expand testing into a larger population base, particularly targeting individuals at high risk for HIV infection.
