At the University of Washington in Seattle, investigators will enroll 5 study participants who have been on ≥2 years of suppressive ART. Study participants will be followed closely for at least 22 months with safety labs and serial measurements of the HIV reservoir (specifically, cell-associated HIV DNA and mRNA (ca-DNA & ca-RNA), quantitative viral outgrowth assay (QVOA), and single copy plasma viral load (scVL)). A "go/no-go" decision will occur after 12 months based on pre-defined thresholds of reduction in the HIV reservoir measured with ca-DNA.
