Brief Summary:
While both conventional and advanced MRI techniques offer important insights into MS pathophysiology, important aspects of this inflammatory disorder are undetectable with existing MRI technology. In Multiple Sclerosis (MS), there is growing interest in PET as an imaging modality that can increase the investigator's understanding of the disease processes and may add to an understanding of MS phenotype, particularly when combined with advanced MRI techniques such as myelin water imaging.

Condition or disease
Multiple Sclerosis

Detailed Description:

This is an exploratory study. PBR28 PET scan is new, promising and exploratory endpoints in MS clinical trials, making sample size estimation difficult.

A separate pre-screening consent form will be issued for the TSPO rs6971 polymorphism and eGFR blood samples, a separate pre-screening step. Eligible participants, according to their TSPO rs6971 polymorphism will be presented a separate study consent form to continue into the clinical trial.

Study Assessments include 1 PET scan, 1 MRI scan, OCT, EDSS exam, physical exam, cognitive questionnaires, etc.

Estimated Study Completion Date : September 2020

Resource links provided by the National Library of Medicine

Multiple Sclerosis (MS) patients
3 Primary Progressive MS patients on no disease modifying therapy and 3 Relapsing-Remitting MS patients on no disease modifying therapy
Healthy Controls (HC)
3 Healthy volunteers aged between 18-60 years of age

Primary Outcome Measures :
  1. Whole Brain PBR28 binding [ Time Frame: January 2020 ]
    To show an increase in 11C-PBR28 binding in all sub-types of MS compared to healthy controls.

Secondary Outcome Measures :
  1. Myelin Water Imaging by MRI [ Time Frame: January 2020 ]
    To quantitatively measure the brain levels of water located within myelin

  2. Optical Coherence Tomography [ Time Frame: January 2020 ]
    To correlate brain levels of inflammation measured by 11C-PBR28 with Retinal Nerve Fiber Layer (RNFL) thickness on Optical Coherence Tomography (OCT).

  3. MS Spectroscopy [ Time Frame: January 2020 ]
    To correlate brain levels of inflammation and myelin measured by PET with cognitive dysfunction in MS patients.
