Hyperpolarized Carbon Metabolic Imaging in Multiple Sclerosis

This study is looking at a new way to image multiple sclerosis (MS) using a special MRI scan. It involves an injection of HP 13C pyruvate during an MRI to see how MS lesions, white matter, and the whole brain use energy. The goal is to see if this imaging method can predict how well people with relapsing-remitting MS (RRMS) will respond to anti-CD20 therapy. You might be able to join if you are 18 or older, have RRMS, haven't taken disease-modifying therapies (DMTs) for at least two years, and plan to start anti-CD20 therapy. The study aims to enroll 40 participants.

Study design
This is an interventional study planning to enroll 40 participants with relapsing-remitting MS. It is a single-arm study, meaning all participants will receive the same intervention.
What's involved
You would receive HP 13C pyruvate injections during MRI scans. Some participants will have a second injection for a repeatability study. You will also have blood draws and standard MS clinical assessments over approximately one year.
Compensation
Not stated in the trial record.
Follow-up
The primary endpoint measures changes up to 1.5 months after starting treatment, with overall study follow-up from initiation to up to 15 months after the last subject is enrolled.

  • To determine the percent changes in MS lesions, white matter, and whole brain HP 13C pyruvate metabolism measures between the pre-treatment scan and the scan obtained 1.5-months following treatment initiation.From study initiation to up to 15 months after enrollment of last subject.

    Percent changes in lesion HP 13C pyruvate metabolism measures. The following metabolism measures will be assessed at baseline and at 1.5-months following treatment initiation * Peak HP 13C lactate/pyruvate and bicarbonate/pyruvate signal-to-noise ratio * HP 13C lactate/pyruvate and bicarbonate/pyruvate AUC ratio * Metabolic rate constants kPL and kPB in inverse seconds.
