Multiple sclerosis trials now focus beyond relapsing-remitting disease to address the progressive forms (PPMS and SPMS) where anti-inflammatory approaches have shown limited efficacy. Remyelination — regenerating the myelin sheath stripped away by the autoimmune attack — is the most transformative target in current MS research, with several promising candidates entering Phase 2.
Active trials evaluate BTK inhibitors (tolebrutinib, fenebrutinib) for progressive forms, remyelinating agents (PIPE-307, CNM-Au8), high-efficacy induction therapies (cladribine, alemtuzumab) in early aggressive disease, and CAR-T cell approaches for treatment-resistant cases. Optical coherence tomography (OCT) and neurodegeneration biomarkers are advancing as trial endpoints.
Frequently Asked Questions — multiple sclerosis Clinical Trials
How many clinical trials are currently recruiting for multiple sclerosis?
ClinicalMetric currently tracks 9 actively recruiting clinical trials for multiple sclerosis, sourced in real time from ClinicalTrials.gov. The total number of registered studies—including those not yet enrolling or in active follow-up—is 9. Trial availability changes daily as new studies open enrollment and existing ones reach capacity.
What trial phases are available for multiple sclerosis?
multiple sclerosis research spans multiple clinical trial phases. Phase 1 studies evaluate safety and dosing in small groups, Phase 2 studies assess preliminary efficacy in 100–300 participants, and Phase 3 trials compare the new treatment against the standard of care in 300–3,000+ patients. Phase 4 post-approval studies monitor long-term outcomes in real-world populations.
How do I find out if I qualify for a multiple sclerosis clinical trial?
Eligibility criteria for multiple sclerosis trials vary by study and typically specify age range, disease stage or severity, prior treatment history, and specific diagnostic or laboratory parameters. Each listing on ClinicalMetric links to the full protocol on ClinicalTrials.gov, where inclusion and exclusion criteria are documented. Contact the sponsoring site's research coordinator directly to confirm your eligibility—your treating physician or specialist can also help identify the most appropriate trial based on your medical history and current treatment status.
