Summary

Patients who have Human Immunodeficiency Virus-1 (HIV-1) infection, who also had a stem cell transplant may have achieved cure of their HIV infection. Once the patients blood shows no detectable levels of HIV virus in their blood collected from a process called leukapheresis, they will be closely monitored while discontinuing their HIV treatment which is know as antiretroviral therapy or, ART. They will be tested regularly and monitored for up to 52 weeks at which point they may be considered cured of their HIV.

Detailed description

On week -1, a HIV VL and CD4 count will be drawn. If VL remains undetectable, at study week 0, and no other exclusion criteria noted, subject will discontinue ART and enter ATI phase of the study. HIV-1 plasma VL will be monitored every 2 weeks for 52 weeks, then patient returns under the care of their HIV provider. CD4 T cell count will be monitored every 4 weeks. Depressions symptom check with PHQ-9 check monthly with study visits. Since patients might be cured and at risk of acquiring HIV during the period of treatment interruption, they will be offered Prep on Demand (Truvada) to be used no more than once a month (with notification of study PI when it happens). When Prep on Demand is used, we will ask patient to come in for ART drug level measurement same week. If patient meets any of the restart ART criteria during the interruption phase, they will discontinue the ATI phase of study and re-start ART and enter the follow up ART phase. If subject maintains undetectable plasma HIV VL (assay quantification threshold 20 copies/mL), they will remain off ART and continue to be monitored until restart criteria are met. If patient meets the restart criteria, they will be followed for 12 months post re-initiation of therapy by their HIV provider. The first month post restart of therapy will require weekly visits, followed by monthly visits thereafter until HIV VL is back \<50 copies/mL. Leukapheresis (per previously approved protocol that patient consented to) will be performed at 6 months and 12 months post ATI if in continued viral remission.
