A Phase I Safety and Immunogenicity Trial of UBI Microparticulate Monovalent HIV-1 MN Peptide Immunogen in HIV-1 Seronegative Human Subjects

Summary

To evaluate the safety and immunogenicity of a new microparticulate formulation of an HIV-1 MN PND peptide for oral administration in healthy, HIV-1 seronegative adult volunteers at low risk for infection. Vaccine formulations of synthetic peptides adsorbed to alum may not provide other requisite characteristics of an effective HIV vaccine, such as induction of mucosal immunity, production of cytotoxic T cells, and ease of administration. An oral microparticulate vaccine containing a prototype synthetic peptide has been developed. The microparticles can be degraded over time, inducing both secretory and systemic immune responses.
