Purpose

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).

HIV Infections

Drug : maraviroc (Selzentry)
Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: 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

Further study details as provided by University of Hawaii:

Primary Outcome Measures

  • Change From Baseline to 24 Weeks in HIV DNA (Log-10 Copies/10^6 Cells) as Measured by HIV DNA Within CD14+ Peripheral Blood Mononuclear Cells [ Time Frame: Baseline to 24 weeks ]
    Week 24 minus baseline
Secondary Outcome Measures:
  • 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.

Enrollment: 15
Study Start Date: January 2010
Study Completion Date: August 2013
Primary Completion Date: November 2012 (Final data collection date for primary outcome measure)

  • 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
