A Phase I Safety and Immunogenicity Trial of Live Recombinant Canarypox ALVAC-HIV (vCP205) in HIV-1 Uninfected Adult Volunteers

Summary

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.
