The HIVconsv gene was constructed by assembling the 14 most conserved regions of the HIV-1 proteome into one chimaeric protein. This gene has been inserted into 2 leading non-replicating vaccine vectors: an attenuated chimpanzee adenovirus serotype 63 (ChAdV63) and a modified vaccinia virus Ankara (MVA) to construct the ChAdV63.HIVconsv and MVA.HIVconsv HIV-1 candidate vaccines. The present study is named ChAd-MVA.HIVconsv-BCN01 and it is a phase I, multicenter primary/booster therapeutic vaccination study to evaluate the safety and immunogenicity of ChAdV63.HIVcons and MVA.HIVconsv HIV-1 vaccines, delivered intramuscularly according to a 0-8 weeks or a 0-24 weeks schedule to recently HIV-1 infected individuals with early viral suppression 6 months after initiation of Tenofovir/Emtricitabine plus Raltegravir.
