| Main Objective: To evaluate viral evolution of patients failing maraviroc;Secondary Objective: Viral evolution will be evaluated as: 1) Proportion of patients that switch viral tropism at EOS compared to baseline. 2) Frequency and change of mutations in the V3 region of Env associated with resistance to maraviroc at EOS compared to baseline 3) Change of viral tropism of the V3 region of Env between screening and baseline 4) Change of mutational pattern of the V3 region of Env between screening and baseline 5)Immunological impact of maraviroc will be evaluated as: -Change in the absolute number of CD4+ T cells from baseline. -Change in the percentage of CD4+ T cells from baseline. -Change in the percentage activated T cells (CD38+ HLA-DR+ CD4+ and CD8+ cells) CCR5+ and CXCR4+ Naïve and Memory cells, from baseline.;Primary end point(s): Proportion of patients with an increase of at least 0.5 Log10 in HIV-1 RNA at W12. | — |
