Clinical Trial Summary

To determine the safety and immunogenicity of 200 mcg MN rgp160 vaccine (Immuno-AG) versus placebo, administered on two immunization schedules to healthy volunteers. Per 06/15/94 amendment, to determine the safety and immunogenicity of 800 versus 200 mcg given as a fourth immunization at 9 or 11 months after the third injection (i.e., at month 17). A gp160 vaccine developed from the IIIB strain of HIV-1 has been found to be safe and immunogenic in healthy adults. Since the MN strain of HIV-1 is representative of a larger proportion of HIV-1 isolates in the United States than is the IIIB strain, evaluation of a gp160 vaccine derived from the MN strain is important.


Description:

A gp160 vaccine developed from the IIIB strain of HIV-1 has been found to be safe and immunogenic in healthy adults. Since the MN strain of HIV-1 is representative of a larger proportion of HIV-1 isolates in the United States than is the IIIB strain, evaluation of a gp160 vaccine derived from the MN strain is important. Volunteers are randomized to receive 200 mcg MN rgp160 or placebo at months 0, 1, and 6 or at months 0, 2, and 8. For each immunization schedule, ten volunteers receive vaccine and two volunteers receive placebo. Per amendment, volunteers receive a fourth immunization of 800 or 200 mcg (or placebo) at 9 or 11 months after the third injection (i.e., at month 17) and are followed for 6 months afterward.
