Maraviroc Intensification and Peripheral Blood Monocyte HIV DNA Levels
February 1, 2017 updated by: University of Hawaii
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
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).

Description
Inclusion Criteria:
- HIV-1 infection as documented by ELISA and confirmed by either Western blot, HIV-1 culture, HIV-1 antigen, plasma HIV-1 RNA by RT-PCR or bDNA at any time prior to study entry.
- Receipt of ARV medication uninterrupted for > 1 year leading up to the screening period with demonstrated HIV RNA < 50 copies/ml for a period of 1 year."
- Willingness for both males and females of childbearing potential to utilize 2 effective contraception methods (2 separate forms, one of which must be an effective barrier method), be non-heterosexually active or have a an exclusive vasectomized partner from screening throughout the duration of the study treatment and for 30 days following the last dose of study drugs.
- Age >18 years.

- Estimated creatinine clearance > 60 mL/min.
- HIV DNA within peripheral blood mononuclear cells > 100 copies/mL
- Not currently receiving Maraviroc as part of ARV regimen
Exclusion Criteria:
- Past or present HIV opportunistic infection of the brain, learning disability, head injury with prolonged loss of consciousness or cognitive sequelae, or other non-HIV risk factor that may impact cognitive performance.

- Any vaccination within 30 days of study entry.
- Requirement for acute therapy for other AIDS-defining illness or other serious medical illnesses (in the opinion of the site investigator) within 14 days prior to study entry.
- Other chronic illnesses including diabetes, autoimmune diseases, and endocrinopathies, except subjects on stable physiologic replacement therapy for low testosterone or thyroid levels
- Known hypersensitivity to Maraviroc
- Any condition which, in the opinion of the investigator, would compromise the subject's ability to participate in the study
- Current active substance or alcohol dependence
- Pregnancy or breast-feeding, intent to become pregnant during the course of the study.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline to 24 Weeks in Neuropsychological Performance As Measured by Age- and Education-Adjusted Z-Scores
Time Frame: Baseline to 24 Weeks
|
The Z-score represents the number of standard deviations away from the mean, with positive Z-scores representing better neuropsychological performance and negative Z-scores representing poorer neuropsychological performance.
Z-scores have been adjusted based on age- and education-matched norms.
