Detailed Description:

HIV-associated neurocognitive disease (HAND), particularly in its milder form, is estimated to occur in greater than 30% of HIV infected individuals in the era of potent antiretroviral therapy. As even mild disease leads to functional consequences with decreased ability to live independently, HAND is of substantial public health concern. HIV-induced immune activation/inflammation of monocytes (MO) may be primarily responsible for the development of HAND.

Cenicriviroc is a combined CCR5 and CCR2 chemokine co-receptor antagonist. The investigators hypothesize that dual CCR5 and CCR2 blockade with the use of CVC will lead to measurable reductions in MO activation and lead to cognitive improvement by decreasing HIV infection of MO and by interrupting the trafficking of such MO into the central nervous system.

The investigators propose a single arm, 24-week trial of CVC in 24 subjects with HIV-1 infection suppressed on ART (plasma HIV RNA < 50 copies/ml) for 1 year or more with mild to moderate cognitive impairment.

Inclusion Criteria:

  • On ARV medication uninterrupted for > 1 year leading up to the screening period
  • Screening plasma HIV RNA < 50 copies/ml within 3 months of entry
  • Willingness for 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 to 70 years
  • Ability and willingness to provide written informed consent
  • Mild to moderate cognitive impairment with global neuropsychological (NP) test (NPZglobal) score of < -0.5 or a neurocognitive abnormality (<-0.5) in at least one cognitive domain known to be typically affected by HIV.
  • On antiretroviral (ARV) therapy consisting of nucleoside reverse transcriptase inhibitors, atazanavir with/or without ritonavir, darunavir plus ritonavir, dolutegravir, raltegravir or efavirenz.

Exclusion Criteria:

Adequate treatment meets current recommendations of the Center for Disease Control, NIH and the HIV Medicine Association of the Infectious Diseases Society of America (IDSA) guidelines or other Center for Disease Control recommendations if patient was treated before the current recommendations or before coinfection with HIV.
  • Prior/current diagnosis with other intracellular pathogens (Listeria monocytogenes, Toxoplasma gondii, and Cryptococcus neoformans).
