Clinical Trial Summary

This study is designed to evaluate the safety of the FLSC vaccine and will be a randomized, placebo-controlled, modified double-blinded dose escalation study in 60 healthy adult volunteers (Human Immunodeficiency Virus-1 uninfected).


Clinical Trial Description

This is a Phase 1 randomized, placebo-controlled, modified double-blinded dose escalation study in 60 healthy adult volunteers who are Human Immunodeficiency Virus-1 (HIV-1) uninfected. Participants in the study will receive 4 injections at 0, 4, 8 and 24 weeks and will be followed for an additional 24 weeks. The total study duration will be 48 weeks. As this is a Phase 1 trial, the primary objective is to document safety of the Full Length Single Chain (FLSC) gp120-CD4 complex vaccine with a secondary objective to evaluate immune responses induced by the vaccine. This vaccine is being evaluated as it is constructed so that the gp120 and CD4 moieties form a stable intra-chain binding interaction that forms a transition state structure that presents conserved, conformational domains involved in the early HIV replication process. It is hypothesized that antibodies directed to these epitopes would be highly cross-reactive and potentially useful for HIV vaccine development. ;
