Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18-65 with a diagnosis of progressive multiple sclerosis and documented evidence of disability progression.

Probably not a fit

Patients with relapsing forms of multiple sclerosis or those with certain comorbidities may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the safety and efficacy of Nicotinamide riboside (NR) in patients with progressive multiple sclerosis. Participants will be randomly assigned to receive either NR or a placebo for a duration of 30 months. The primary objective is to determine whether NR can delay disability progression in individuals diagnosed with progressive forms of MS. The study employs a double-blind design to ensure unbiased results.

Why it matters

Potential benefit: If successful, this treatment could slow down the progression of disability in patients with progressive multiple sclerosis.

How similar studies have gone: While the use of nicotinamide riboside is a novel approach in this context, similar studies targeting metabolic pathways in MS have shown promise.
