A clinical trial to assess the safety and tolerability of THV01, a therapeutic treatment against HIV composed of two vaccines, in HIV-infected patients treated by antiretroviral treatment. Three doses will be assessed and a control group of patients who will receive a placebo (non-active product) is included. The immune response generated by the THV01 treatment will also be assessed.
