Trial summary

Multiple sclerosis (MS) is an immune-mediated chronic inflammatory demyelinating disease of the central nervous system. Its main feature is progressive demyelination, which ultimately leads to axon damage and neuron loss. MR is the main imaging technique in the current diagnostic criteria of MS.

About this study

Official title: Hybrid PET/MR Imaging to Assess Demyelination and Axonal Injury in Multiple Sclerosis

Multiple sclerosis (MS) is an immune-mediated chronic inflammatory demyelinating disease of the central nervous system. Its main feature is progressive demyelination, which ultimately leads to axon damage and neuron loss. MR is the main imaging technique in the current diagnostic criteria of MS. The conventional MR sequence recommended in this diagnostic criteria has high sensitivity for detecting demyelination and axon damage, but has poor specificity, which makes disease modification therapy (DMT) blind, and it is also difficult to accurately determine the long-term prognosis.

PET is a non-invasive molecular imaging technology that can quantitatively monitor physiological or pathological processes in vivo. 18F-labeled thioflavin derivative probe (18F-florbetapir) can bind to myelin basic protein in the white matter, providing quantitative assessment of myelin content. Our preliminary studies have confirmed that the uptake of 18F-florbetapir in MS lesions is significantly related to the myelin content measured by histological staining. Therefore, 18F-florbetapir PET may be a very effective myelin imaging technology.

Advanced MR sequence such as magnetic resonance spectroscopy (MRS) can evaluate axonal damage by analyzing neuronal activity marker N-acetyl aspartate (NAA). The new whole-brain fast 3D MRS sequence breaks through the bottleneck of low signal-to-noise ratio and spatial resolution of the current MRS sequence, and provides a reliable method for obtaining neuronal activity markers in the three-dimensional space of MS sporadic lesions in the whole brain.

Integrated PET/MR makes PET detector implant in the MR magnet, which realizes the simultaneous acquisition of PET and MR in one scan, ensuring the high consistency of the two modes. This makes it possible to simultaneously analyze PET and MRS quantitative parameters in multiple and different sizes of MS lesions, that is, to obtain two different pathological features of demyelination and neuronal damage. Separating these two pathological changes will help to more accurately and quantitatively evaluate the efficacy of DMT, program selection and prognostic judgment.

This project intends to recruit 30 MS patients between 18-65 years old, and 30 healthy volunteers with matched age and sex as normal controls. PET/MR imaging, serological examination and cerebrospinal fluid testing and scale evaluation will be performed. The aim of this project is to planned to establish a new imaging evaluation technology for accurate diagnosis and prognosis evaluation of MS.

Questions about this trial

What is this clinical trial studying?

A study testing 18F-florbetapir PET+MRSI in people with Multiple Sclerosis, run by Ruijin Hospital at 1 site in China.

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 6 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 25 Oct 2022. 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 China. 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. Some participants in this study may receive a placebo. 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?

Distribution Volume Ratio (DVR) (time frame: Baseline). The study lists 9 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 25 Oct 2022.
