Summary

To evaluate the safety and immunogenicity of live recombinant canarypox ALVAC-HIV vCP205 in combination with recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF) at 80 microg and 250 microg. \[AS PER AMENDMENT 4/30/99: To study the safety of following 4 ALVAC immunizations with a nucleic acid gag/pol HIV-1 immunogen (APL-400-047, Wyeth-Lederle). To assess the ability of this sequence of immunization to boost the LTL, T-helper cell, and antibody response.\] ALVAC-HIV candidate vaccines have induced HIV-specific CTL responses in more than half of recipients in some protocols. Depending on the HIV-1 gene products expressed by the particular ALVAC-HIV candidate vaccine, volunteers have generated anti-Envelope (vCP125, vCP205, and vCP300), anti-Gag (vCP205 and vCP300), and anti-Nef (vCP300) CTL activity. Although 3 to 4 immunizations with the different ALVAC-HIV experimental vaccines induce anti-HIV-1 neutralizing antibodies in a portion, often the majority, of volunteers, the geometric mean titers of these antibodies are modest, usually less than 50. This study will determine whether there is an increase in the anti-HIV antibody titers when GM-CSF is used as an adjuvant with ALVAC-HIV vCP205 and will also examine the kinetics and magnitude of the HIV-specific CTL response.
