Autologous CD4 T-Cells in HIV (C34-CXCR4)

all participants will receive a single infusion of C34-CXCR4-modified CD4+ T-cells at one of 3 dose levels. The first 3 subjects will receive dose level 1 of 0.8-1x109 transduced CD4+T-cells. Provided no dose limiting toxicity (DLT) is seen at the first dose level, the next 3 subjects will receive infusion at the 2nd dose level of 2.4-3x109 transduced CD4+ T-cells. If no DLT occurs at that dose, the final 3 subjects will receive the 3rd dose level of 0.8-1x1010 transduced CD4+ T-cells. In the event of a DLT (grade 3 or higher unexpected, related AE) recruitment will be paused pending DSMB decision
