Repeated DermaVir Immunizations in HIV-1 Infected Treatment-naïve Patients

Summary

DermaVir is a synthetic pathogen-like nanomedicine. The active pharmaceutical ingredient is a single plasmid DNA expressing fifteen HIV antigens that assemble to HIV-like particles. These particles are safe; replication, integration and reverse transcription deficient. DermaVir is targeted to Langerhans cells by topical administration with DermaPrep. Langerhans cells with DermaVir migrate to lymph nodes and induce HIV-specific T cells that can kill HIV-infected cells. GIEU006 is a Phase II randomized, placebo-controlled, dose-finding, double-blinded, multicenter study to assess the safety, tolerability, immunogenicity, and preliminary antiretroviral activity of DermaVir in antiretroviral therapy naïve adults with HIV-infection.
