Multiple sclerosis affects about 1 million people in the United States. Treatment now includes more than 20 disease-modifying therapies, ranging from injections to pills to twice-yearly infusions. Many people with relapsing MS now go years without new attacks, and research is shifting attention to progressive forms and to repairing damage already done.
What's actually going on in research
Trials are testing BTK inhibitors that may reach progressive MS, remyelinating drugs that aim to repair the damaged nerve coating, stem cell transplant for aggressive disease, and new approaches to fatigue and cognitive symptoms. Researchers are also studying the role of Epstein-Barr virus, which appears to trigger MS in many people, and testing higher-potency drugs earlier in disease.
BTK inhibitors
A new class of pills crosses into the brain and may calm MS at a deeper level than current drugs. Trials are testing whether they can slow progressive forms of MS where options have been limited.
Remyelination therapies
Several drugs aim to rebuild the myelin coating damaged by MS. If successful, they could restore function rather than just prevent new attacks.
Stem cell transplant
Hematopoietic stem cell transplant is being tested for aggressive MS. Early studies suggest it may reset the immune system and stop disease activity for years in select patients.
What to know before you search
Eligibility often depends on MS type (relapsing or progressive), recent relapse or MRI activity, prior treatments, disability level measured by EDSS score, and time since diagnosis.
What types of trials are currently open
- Disease-modifying trials — Testing new MS medications, often pills or longer-acting infusions, to see if they prevent relapses and slow disability progression better than current drugs.
- Progressive MS trials — Testing drugs aimed at slowing or stopping primary or secondary progressive MS, where treatment options have historically been limited.
- Repair and recovery trials — Testing drugs that aim to repair myelin damage or restore nerve function, potentially reversing existing disability.
- Symptom management trials — Testing treatments for fatigue, walking problems, bladder issues, cognitive symptoms, and spasticity that interfere with daily life.
- Observational studies — Following people with MS over time to learn how the disease progresses, what predicts response to treatment, and how lifestyle factors affect outcomes.
Recently added Multiple Sclerosis trials
A Study of IMS001 in Patients With Multiple Sclerosis
This study will evaluate the safety and tolerability of IMS001 and explore its possible effects in adults with multiple sclerosis. IMS001 is an investigational cell therapy consisting of mesenchymal-like stem cells derived from human embryonic stem cells. The study plans to enroll 4 adults aged 18 to 65 years with relapsing-remitting or secondary progressive multiple sclerosis in China. Each participant will receive a single infusion of IMS001 into a vein. All participants will receive IMS001, and both participants and the study team will know which treatment is given. Participants will undergo screening for up to 4 weeks before treatment. After the infusion, they will be assessed over 12 months for side effects and changes in multiple sclerosis, including relapses, disability, brain magnetic resonance imaging (MRI) findings, vision, movement, and thinking abilities. Participants will then enter an additional 24-month follow-up period to monitor long-term safety, including serious side effects and possible tumor development. Total participation may last up to 37 months, including screening.
Investigating the Impact of Treadmill-integrated Virtual Reality Training on Walking Outside the Clinic
This study will test whether a treadmill-based virtual reality walking program is safe, practical, and helpful for people with multiple sclerosis (MS). Participants will complete a 6-week training program and wear smart socks that measure how they walk before, during, and after the program. The study will also track changes in balance, fatigue, fall risk, fear of falling, confidence with walking, and overall quality of life.
