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

Phase 1

Completed

• Conditions: HIV Infections

• Registration Number: NCT00000798
• Lead Sponsor: National Institute of Allergy and Infectious Diseases (NIAID)

Brief 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.

Detailed Description

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.

Twelve volunteers per dose regimen will receive oral microparticulate multivalent HIV-1 peptide vaccine at months 0, 1, and 6, either daily as a low dose for 3 days or a single higher dose. Additionally, four volunteers per regimen will receive placebo. Volunteers are followed for 1 year. They will be contacted once or twice yearly for 5 years to check on health status.
