A Safety and Immunogenicity Study of a Plasmid DNA Prime and MVA Boost Vaccine in HIV-1 Infected Adults on ART

HIV-1 Infection Clinical Trial

Official title:
A Phase 1 Clinical Trial to Evaluate the Safety and Immunogenicity of pGA2/JS7 DNA and MVA/HIV62B in HIV-infected Adults With Suppressed Viremia Who Started ART Within 18 Months of a Negative HIV Antibody Test

Clinical Trial Summary

GV-TH-01 is an open label Phase 1 study of 9 HIV-1 infected adults with suppressed viremia who started anti-retroviral therapy (ART) within 18 months of a negative HIV antibody test. This study has 3 phases. The first phase is the vaccination phase, where patients are vaccinated with pGA2/JS7 (JS7)DNA and MVA62B vaccines on a prime/boost regimen. The second phase of the study is a treatment interruption phase, whereby ART is interrupted for a 12 week period approximately 8 weeks following the last vaccination. The third phase occurs after the 12 week treatment interruption phase and is called the treatment reinstitution phase, because subjects reinstitute ART and are followed for an additional 24 weeks. The primary objective is to evaluate the safety of the vaccines during the three phases of the study. A secondary objective is to evaluate the immunogenicity of the vaccines during the vaccination phase of the study.

Clinical Trial Description

GV-TH-01 is an open label Phase 1 study of 9 HIV-1 infected adults with suppressed viremia who started anti-retroviral therapy (ART) within 18 months of a negative HIV antibody test. This study has 3 phases. The first phase is the vaccination phase, where patients are vaccinated with pGA2/JS7 (JS7)DNA and MVA62B vaccines on a prime/boost regimen at weeks 1 and 9 (JS7 DNA vaccine) and weeks 17 and 25 (MVA62B). Both vaccines express Gag, Pol, and Env. The second phase of the study is a treatment interruption phase, whereby ART is interrupted for a 12 week period approximately 8 weeks following the last vaccination. The third phase occurs after the 12 week treatment interruption phase and is called the treatment reinstitution phase, because subjects reinstitute ART and are followed for an additional 24 weeks. The primary objective is to evaluate the safety of the vaccines during the three phases of the study. A secondary objective is to evaluate the immunogenicity of the vaccines during the vaccination phase of the study. ;
