Study summary

This project will investigate the ability of a novel MRI contrast agent to identify and quantitate ongoing monocyte/macrophage (M/MΦ)-mediated inflammation in the brains of HIV-infected individuals.

Read the detailed description

HIV-associated neurocognitive disorders (HAND) continue to be prevalent despite effective combination antiretroviral therapy (cART) and have a significant impact on morbidity and quality of life. Monocytes/macrophages (M/MΦ) are believed to play a critical role in the pathogenesis of HAND. Neuroimaging HIV research has not focused on assessing M/MΦ-mediated inflammation in the brain. Currently, no neuroimaging modality exists that can define the extent of active inflammation due to M/MΦ in HAND either as a clinical diagnostic tool or to assist in defining objective improvement in clinical trials addressing HAND. Ferumoxytol is an ultra-small iron oxide MRI contrast agent avidly taken up by circulating M/MΦ. The investigators hypothesize that ferumoxytol-based imaging can identify ongoing inflammation due to perivascular M/MΦ which is believed to represent a key pathologic correlate of HAND.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Age 40-65 years
  • Plasma RNA \< 48 copies/ml (HIV+ subjects only)
  • On stable cART >= 1 year (HIV+ subjects only)
  • Global neuropsychological (NP) score \<-0.5 in at least one cognitive domain known to be affected by HIV (neurocognitively impaired subjects only)
  • Documentation of negative HIV infection by an FDA approved test (HIV- subjects only)

Exclusion criteria

Exclusion Criteria:

  • Active substance use
  • History of myocardial infarct or stroke
  • Diabetes
  • Chronic virus (HCV) infection
  • Uncontrolled major affective disorder, active psychosis, central nervous system disease that affects the brain structure, or other uncontrolled chronic medical condition that in the opinion of the investigator may impact NP testing or the study outcome
  • Psychoactive or other medications which may impact NP testing
  • Factors that preclude MRI
  • Known to ferumoxytol
  • History of laboratory measurements consistent with an iron overload syndrome
  • Medical conditions that require frequent blood transfusions
  • Taking oral iron supplements
  • Elevated iron levels
  • Any condition, which in the opinion of the investigator, would compromise the subject's ability to participate
  • Multiple drug allergies that may pose a greater risk of anaphylaxis associated with ferumoxytol
  • Pregnant, unwillingness to practice , or breastfeeding
  • Unable to give
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • Experimental
    HIV+ with neurocognitive disorder

    All subjects will receive neurocognitive testing. Subjects will have a brain MRI prior to drug infusion. A one-time ferumoxytol IV infusion will be given at a dose of 4mg Fe/kg up to a maximum of 510mg of elemental iron delivered at a rate of 1ml/sec. A second brain MRI will be completed post-infusion

    Drug: Ferumoxytol

  • Active comparator
    HIV+ without neurocognitive impairment
