Tamovac I

A Phase I/II trial to assess safety and immunogenicity of intradermal (ID) DNA priming, intramuscular (IM) MVA and IM rgp140/GLA-AF boosting in healthy volunteers in Tanzania and to develop further HIV vaccine trial capacity building in Tanzania.

The aim of the Tamovac I trial is to further explore the optimal method for delivery of HIV-1 DNA priming.

What is this study about?

HIV is a significant health problem globally, but especially in developing countries. Efforts towards a safe, affordable and efficacious vaccine have seen the development of partnerships between the North and South in the search for an HIV vaccine.

The primary objectives of this study are:

-to determine the safety and immunogenicity of vaccination with HIVIS-DNA at 2 doses delivered ID and boosted with proteins MVA-CMDR and rgp140/GLA-AF.

The secondary objectives are:

-to compare the immunogenicity of HIVIS-DNA at a dose of 600 µg given as combined plasmid pools or separate plasmid pools ID.

-to explore the safety and immunogenicity of boosting with two doses of rgp140 in the adjuvant GLA-AF, administered IM.

-to build and sustain expertise and the capacity to conduct HIV vaccine trials in Tanzania.
