|Condition or disease||Intervention/treatment||Phase|
|HIV-1-infection||Drug: There are no disallowed treatments||Phase 1|
Subjects infected with HIV who have received therapy with SB-728-T or SB-728mR-T and have completed 3 years of post-infusion follow-up will be eligible to participate in this trial. There will be no treatment in this long-term follow-up study. Subjects who choose to enroll into this extension study will be evaluated for a total of 12 years.
An optional leukapheresis may be performed upon sponsor request.

Experimental: Cohort 1
Long-term follow-up of HIV-infected subjects who received SB-728-T or SB-728mR-T in a previous trial.
Drug: There are no disallowed treatments
Genetic: SB-728-T or SB-728mR-T No study drug is administered in this study. Subjects who received SB-728-T or SB-728mR-T in a previous trial will be evaluated in this trial for long-term safety and efficacy.
- Long-term safety of treatment with SB-728-T or SB-728mR-T [ Time Frame: 12 years ]Number of subjects with delayed adverse events associated with administration of SB-728-T or SB-728mR-T, autologous T-cells genetically modified at the CCR5 gene by zinc finger nucleases.
- Long-term persistence of SB-728-T or SB-728mR-T [ Time Frame: 2 years ]Long-term persistence of SB-728-T or SB-728mR-T will be measured by serial measurement of CCR5 gene modification.
- Change in HIV reservoirs [ Time Frame: 2 years ]Change in HIV reservoirs will be measured by serial measurement of HIV-1 RNA, HIV proviral DNA and HIV Co-receptor Tropism
