About this study

Official title: Neuroimaging Correlates of Monocyte/Macrophage Infiltration in HIV-infected Individuals: A Cross-sectional Pilot Study Using IV Ferumoxytol

The purpose of this study is to describe the radiologic findings on brain MRI after ferumoxytol administration in HIV-infected patients with cognitive impairment.

Read the detailed description

The continued existence of cognitive dysfunction in HIV infected individuals in the era of effective antiretroviral therapy may be, in part, secondary to the failure of current antiretroviral regimens to eradicate the pool of HIV-infected and activated monocytes within the bloodstream. Trafficking of such HIV infected and activated blood monocytes into the brain parenchyma is believed to introduce HIV into the brain and precipitate immune activation and inflammation, ultimately leading to neuronal degeneration.

Ferumoxytol is an ultrasmall superparamagnetic iron-oxide (USPIO), which is FDA-approved for intravenous iron-replacement therapy in anemic patients with chronic kidney disease. The paramagnetic properties of ferumoxytol also allow it to be used as a MRI contrast agent. Ferumoxytol is avidly taken up by circulating monocytes and reactive astrocytes, microglia, and dendritic cells within the brain, making it potentially a novel biomarker for HIV-associated cognitive impairment given the role of monocytes in its pathogenesis.

This proposal intends to investigate the possible use of ferumoxytol (a new MRI contrast agent) as a biomarker for HIV-associated cognitive impairment and to assess the safety and tolerability of ferumoxytol in HIV-infected individuals.

Hypotheses to be tested:

  • HIV-infected subjects with undetectable plasma HIV RNA levels and detectable levels of HIV DNA in CD14+ peripheral blood mononuclear cells (PBMCs) and impairment on neurocognitive testing will demonstrate ferumoxytol contrast enhancement in the perivascular regions of the brain consistent with monocyte/macrophage infiltration in these regions.
  • Ferumoxytol can be safely administered to HIV-infected subjects.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • FerumoxytolDrug

    Also called FERAHEME

    A dose of 4 mg/kg of ferumoxytol up to a maximum of 510 mg of elemental iron will be administered.

Study groups in NCT01665846
Study groupRoleWhat they receive
FerumoxotyolExperimentalBrain MRI will be performed before and 48 +/- 8 hours after ferumoxytol administration.
Receives: Drug: Ferumoxytol

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Post-ferumoxytol enhancement on Brain MRI

    The location and extent of ferumoxytol enhancement within the brain will be described.

    Measured: 48 hour following administration of a dose of 4 mg/kg of feruomoxytol up to a maximum of 510 mg of elemental iron

Secondary outcomes (1)
  1. Safety

    The rate of overall grade > 2 toxicities (categorized by the NIAID Division of AIDS adverse events table) during ferumoxytol infusion and 1 month post-ferumoxytol infusion will be assessed.

    Measured: 1 hour and 1 month following administration of a dose of 4 mg/kg of ferumxotyol up to a maximum of 510 mg of elemental iron

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Ferumoxytol in people with HIV Dementia, run by University of Hawaii at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Post-ferumoxytol enhancement on Brain MRI (time frame: 48 hour following administration of a dose of 4 mg/kg of feruomoxytol up to a maximum of 510 mg of elemental iron). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01665846, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Jun 2018.
