Understanding Multiple Sclerosis Clinical Trials

With over 20 FDA-approved disease-modifying therapies (DMTs) — from interferon beta to highly effective B-cell depleting agents like ocrelizumab (Ocrevus) and ofatumumab (Kesimpta) — multiple sclerosis treatment has advanced dramatically through clinical trials over the past three decades. Yet significant unmet needs remain, particularly for progressive forms of MS where treatment options are limited, and for repair of existing nerve damage. Clinical trials today are pursuing the next frontier: remyelination therapies that aim to restore lost neurological function, not just prevent further damage.

Why Consider a Clinical Trial?

While current DMTs can reduce relapses and slow disability accumulation in relapsing MS, no approved therapy can repair myelin damage that has already occurred or effectively halt progression in most patients with primary or secondary progressive MS. Clinical trials are the only route to accessing remyelination agents, neuroprotective compounds, and advanced cell therapies that target these unmet needs. Even for patients with relapsing MS who are doing well on current therapy, trials may offer access to treatments with better safety profiles, more convenient dosing (such as longer intervals between infusions or oral alternatives to injections), or combination strategies that address both inflammation and neurodegeneration simultaneously. Participation also provides access to advanced MRI monitoring and biomarker tracking that can detect disease activity with greater sensitivity than routine clinical care.

Frequently Asked Questions

Common questions about Multiple Sclerosis clinical trials

It depends on the trial. Some trials allow concurrent DMTs, particularly those studying add-on therapies or symptom management. Others require a washout period from your current DMT before starting the investigational treatment. The washout requirements and timing vary based on which medication you are currently taking and the trial protocol.

Yes. There is a growing number of trials focused on primary progressive MS (PPMS) and secondary progressive MS (SPMS). These trials test BTK inhibitors, neuroprotective agents, remyelination therapies, and combination approaches. Progressive MS trials are a high priority for the research community because effective treatments remain limited.

Most MS trials include MRI scans at screening, baseline, and then every 3 to 6 months during the treatment period. Some trials require more frequent scanning in the early months. These scans are covered by the trial sponsor and use advanced protocols that may detect changes not visible on routine clinical MRI.

Remyelination trials test drugs that aim to repair the protective myelin coating around nerves that is damaged in MS. Unlike current DMTs that reduce inflammation, remyelination therapies could potentially restore lost function. These trials typically measure outcomes using specialized MRI, visual evoked potentials, and functional assessments over 6 to 12 months or longer.
