Trial summary

This study is being done in order to see how gadolinium-based MRI contrast (Magnevist) travels through the central nervous system (CNS) when injected through the spinal column, and to compare differences between two age groups (age 20-50, and 51-80). Read more about this study

About this study

Official title: Evaluation Of Brain Glymphatic Kinetics Following Intrathecal Administration Of Gadolinium In Healthy Adult Volunteers

This study is being done in order to see how gadolinium-based MRI contrast (Magnevist) travels through the central nervous system (CNS) when injected through the spinal column, and to compare differences between two age groups (age 20-50, and 51-80). This will allow investigators to evaluate how much contrast has crossed into the tissue surrounding the brain. Such information will help investigators determine whether this kind of contrast can be used to model how other drugs might travel through the CNS and evaluate its use as an illustrative imaging marker that mirrors the glymphatic system.

Read the detailed description

This is a prospective, longitudinal study of MR imaging of intrathecally delivered gadolinium contrast (Magnevist, Gd-DTPA) in healthy adult male and female subjects. Subjects will be divided into two groups (20-50 years old and 51-80 years old) both of which will receive intrathecal injection of the drug Magnevist (Gd-DTPA), followed by serial MR imaging over the course of 10-12 hours. The purpose of the study is determine the transport kinetics of Central Nervous System (CNS) exposure to gadolinium contrast injected into the lumbar intrathecal space (lower back) and evaluate changes with age. This will allow investigators to evaluate the brain parenchymal penetration of gadolinium as an illustrative imaging marker that mirrors the glymphatic system. Investigators hypothesize the exposure and penetration patterns of the neuraxis to neurotherapeutic drugs can be modeled using gadolinium intrathecal contrast administered in the lumbar intrathecal space.

Questions about this trial

What is this clinical trial studying?

A study testing MR Imaging and CT-guidance in people with Healthy, run by Weill Medical College of Cornell University 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 8 inclusion and 13 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 12 Feb 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.

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?

Drug distribution over time (time frame: 6 time-points over 12 hours). 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 12 Feb 2018.
