Maraviroc and NeuroAIDS Pathogenesis

August 27, 2021 updated by: University of Hawaii
Maraviroc is an antiretroviral medication that may help in improving mental function in HIV infected patients with mental problems by decreasing inflammatory tendencies. We will test this in a clinical trial of 42 HIV infected individuals with some mild to moderate mental problems who are already on HIV medications and doing well. We will add Maraviroc or a sugar pill to their HIV medications and see if mental function improves over 48 weeks. This study will be conducted at 2 sites in Hawaii and Puerto Rico.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

We hypothesize that maraviroc (MVC) will lead to improved cognition as assessed by improvement in neuropsychological (NP) performance. We hypothesize that MVC therapy leads to (1) decrease in HIV infection of monocytes (MO), particularly of CD16-expressing MO and (2) phenotypic and functional secretory changes suggestive of decrease in MO immune activation, and that these changes will lead to less HIV infected activated MO trafficking to the CNS, less CNS inflammation and neuronal damage, and ultimately improved cognition. We will test this in a 48 week trial in 42 HIV infected individuals on suppressive antiretroviral therapy (ART) with mild to moderate cognitive dysfunction. These individuals will be randomized to intensify their ART in double-blind fashion to MVC vs placebo. The primary endpoint will be change in NPZglobal. Magnetic resonance spectroscopy (MRS)/magnetic resonance spectroscopic imaging (MRSI) will be conducted to assess potential alterations in inflammatory and neuronal brain chemicals.

Phase

Phase

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
