History of Changes


The study hypothesis is that cenicriviroc will improve cognition in HIV infected individuals with cognitive impairment. The investigators will study the effect of cenicriviroc on cognition in 24 subjects over a 24 week period.

Primary Outcome Measures

  • Change from baseline to week 24 in Neuropsychological Performance utilizing a battery of neuropsychological tests [ Time Frame: baseline, week 24 ]
    To assess 24 week change in global and domain-specific neuropsychological performance following CVC intensification
Secondary Outcome Measures:
  • Number of participants who experience temporary or permanent study drug discontinuation due to intolerability [ Time Frame: Up to 24 weeks ]
  • Cenicriviroc plasma drug levels [ Time Frame: week 2 ]
    plasma levels on dosage selected for patient
  • Change in plasma HIV RNA from baseline to week 24 [ Time Frame: Baseline, week 4, week 24 ]
  • Change in CD4 count from baseline to week 24 [ Time Frame: Baseline, week 24 ]
  • Change in fasting metabolic parameters (glucose, insulin, total, LDL and HDL cholesterol, triglycerides) [ Time Frame: baseline, week 24 ]
  • Number of participants who experience grade 2 or higher adverse events [ Time Frame: Up to 28 weeks ]
  • Change in total numbers of activated monocytes by flow cytometry phenotype [ Time Frame: baseline to week 24 ]
    Activated monocytes, defined by flow cytometry as blood cells bearing the CD14 surface receptor (indicating monocytes) and bearing the CD16 surface receptor (indicating activation)

Enrollment: 20

Other Name: TBR-652

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.



Ages Eligible for Study: 18 Years to 70 Years

Inclusion Criteria:

  • Documentation of HIV-1 infection by an FDA approved test at any time prior to study entry
  • 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 OR unimpaired
  • On antiretroviral (ARV) therapy consisting of nucleoside reverse transcriptase inhibitors, atazanavir with/or without ritonavir, darunavir plus ritonavir, dolutegravir, raltegravir or efavirenz.

Exclusion Criteria:
  • Receiving or used a CCR5 antagonist within 6 months of study entry
  • Plasma HIV RNA > 100 copies/ml within 6 mo. of screening
  • HIV-2
  • Chronic hepatitis B (positive hepatitis B surface antigen)
  • Chronic hepatitis C (positive hepatitis C antibody), except with proof of viral clearance and normal liver function tests
  • Active or chronic liver disease
  • Active or inadequately treated tuberculosis infection, or inadequate treatment for a positive purified protein derivative test. 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).
  • Uncontrolled seizures
  • Current or past malignancies excluding basal cell cancer and Kaposi's sarcoma (skin).
  • Immunomodulator, HIV vaccine, any other vaccine, or investigational therapy within 30 days of entry.
  • Requirement for acute therapy for AIDS-defining or other serious medical illnesses within 14 days of entry.
  • Other chronic illnesses including hematologic, pulmonary, autoimmune diseases and endocrinopathies, except for stable controlled diabetes or cardiovascular disease in the view of the investigator and stable testosterone or thyroid therapy.
  • Known hypersensitivity to CVC or its excipients
  • Anticipated need for prescription medication not allowed in the study. Unwilling to stop eating grapefruit or using St. John's wort).
