High levels of HIV infection within blood monocyte/macrophages (a type of white cells in the bloodstream) increases risk of dementia in HIV-infected individuals. Maraviroc (Selzentry) is a HIV medication that works by blocking the entry of HIV in cells including monocytes/macrophages that use a receptor called CCR5. The study hypothesis is that the addition of Maraviroc to a HIV antiretroviral regimen in HIV-infected individuals with high levels of HIV-infected monocyte/macrophages will lead to a decrease in the levels of infected monocyte/macrophages and to decrease in brain inflammation as studied by magnetic resonance spectroscopy (MRS, a form of MRI study).
Drug: maraviroc (Selzentry)
||Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
||Pilot Study of the Effect of Maraviroc Intensification on Peripheral Blood Monocyte HIV DNA Levels When Given to HIV-Infected Subjects Stable on Highly Active Antiretroviral Therapy With Undetectable Plasma HIV RNA
Primary Outcome Measures:
- Change in peripheral blood monocyte HIV DNA (HIV DNA within CD14+ PBMCs) [ Time Frame: week 24 of study ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
- Safety and tolerability of intensification with maraviroc [ Time Frame: 24 weeks ] [ Designated as safety issue: Yes ]
- Change in HIV DNA overall in PBMCs and in CD14- cells [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
- Change in plasma HIV RNA and CD4 count [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
- Change in neuropsychological testing parameters [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
