Primary Outcome Measures
NameTimeMethod
The safety and feasibility of introducing Cal-1 gene-transduced CD4+ lymphocyte and CD34+ bone marrow stem cells following chemotherapy conditioning with intravenous busulfan in HIV-1-infected adults receiving effective ART.<br><br>This is a composite outcome, assessing adverse events and correlations with the Cal-1 gene-transduced CD4+ lymphocyte and CD34+ bone marrow stem cell product dose and characteristics. This outcome is assessed by physical examinations and vital signs, complete blood counts, serum biochemistry, lymphocyte phenotyping, HIV-1 plasma viral load, and HIV-1 ART resistance genotype testing.[48weeks after receipt of the Cal-1-modified cells]
