Trial summary

Aging is the primary risk factor in aging-related dementia. An important initiating factor for the development and progression of cognitive impairment is disruption of the blood-brain barrier (BBB). BBB plays an important role in maintaining normal brain homeostasis and protecting neural tissues from toxins. Read more about this study

  • Ages 20 to 85 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: Healthy cognitively normal control subjects of both age cohorts will be recruited by the study coordinator from (i) a pool of established volunteer subjects at NYU Langone Health who previously participated in research and who have agreed to be contacted about future research, (ii) Health Insurance Portability and Accountability Act of 1996 (HIPAA)-compliant databases such as RedCap and DataCore, and (iii) individuals who have contacted NYU to express interest in participating in research as a healthy volunteer. Subjects with aMCI will be recruited by Dr. Wisniewski from an ongoing NIH-funded large grant at NYU Barlow Center.

Who may be able to join

  • Subjects that have been diagnosed with aMCI ages 65-85

Who cannot join

  • Pregnant, planning to get pregnant, or nursing.
  • Claustrophobia

  • Intracranial clips, metal implants, unremovable jewelries, metal in eyes.
  • History or presence of any other major medical, neurologic or psychiatric conditions, such as Alzheimer's diseases, Parkinson's diseases, and stroke.
  • Renal or liver disease as this may cause concerns related to Gad-based contrast agent

About this study

Official title: Developing Advanced Blood-Brain Barrier Permeability Imaging for Early Alzheimer's Disease

Aging is the primary risk factor in aging-related dementia. An important initiating factor for the development and progression of cognitive impairment is disruption of the blood-brain barrier (BBB). BBB plays an important role in maintaining normal brain homeostasis and protecting neural tissues from toxins. It is hypothesized that such changes known to be common in aging and can be an early process that precedes Alzheimer's Disease (AD). The microvascular changes related to subtle BBB disruption can be measured with permeability-surface area (PS) derived from GRASP DCE-MRI acquired less than 10 minutes, and the patterns of increased PS in normal and abnormal aging are different.

Being tested
GRASP Dynamic Contrast-Enhanced (DCE) MRI, 3T Brain Scan, Gadolinium-based Contrast Agent (GBCA) for MRI

What participants receive

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

  • GRASP Dynamic Contrast-Enhanced (DCE) MRIDevice

    Golden-angle Radial Sparse Parallel (GRASP) DCE MRI is an MRI sequence designed to improve spatial and temporal resolution while enabling retrospective reconstruction with flexible temporal resolution.

  • 3T Brain ScanDevice

    Up to 60 minutes, a portion of which uses the GRASP DCE-MRI sequence.

  • Gadolinium-based Contrast Agent (GBCA) for MRIDrug

    Also called Gadavist/Gadobutrol

    Gadavist/Gadobutrol is a gadolinium-based contrast agent indicated for intravenous use in diagnostic magnetic resonance imaging (MRI) in adults and children (2 years of age and older) to detect and visualize areas with disrupted blood brain barrier (BBB) and/or abnormal vascularity of the central nervous system.

What is being measured

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

  1. Permeability Surface Area (PS) as Measured by GRASP DCE-MRI Sequence

    PS is measured by quantifying the contrast agent flow through blood vessel walls per unit volume of brain while accounting for the blood flow rate in the vessel.

    Measured: Up to 21 Minutes

  2. Blood-Brain Barrier (BBB) Permeability as Measured by GRASP DCE-MRI Sequence

    Golden-angle Radial Sparse Parallel (GRASP) dynamic contrast-enhanced (DCE) MRI sequence will be collected for the quantification of subtle BBB leakage throughout the brain.

    Measured: Up to 21 Minutes

Questions about this trial

What is this clinical trial studying?

An observational study of Alzheimer Disease, run by NYU Langone Health 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 1 inclusion and 7 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 30 Jan 2024. 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.

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?

Permeability Surface Area (PS) as Measured by GRASP DCE-MRI Sequence (time frame: Up to 21 Minutes). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 30 Jan 2024.
