Chronic progressive multiple sclerosis

This phase 3 trial compares two drugs for primary progressive multiple sclerosis (PPMS), a form of MS that steadily worsens. About 985 adults with PPMS will receive either daily oral fenebrutinib or intravenous ocrelizumab (plus matching placebos) to see which better delays disab…

This UK trial tests whether cladribine tablets, taken for just 8-10 days a year over two years, can slow the loss of hand function in people with advanced multiple sclerosis (MS). The study includes 204 participants with significant disability (EDSS 6.5-8.5). Half receive cladrib…

This early-phase trial tests a single dose of YTB323, a CAR-T cell therapy, in 28 adults with non-active progressive multiple sclerosis. The study aims to check safety and track disability changes over time. Participants must be 18–60 and able to undergo lumbar punctures and MRIs…

This study tests the long-term safety of the drug tolebrutinib in 2,500 adults with relapsing or progressive multiple sclerosis. Participants previously took part in earlier trials and will continue taking tolebrutinib or a placebo for up to several years. The goal is to see if t…

This phase 3 trial tests whether rituximab, a cheaper drug, works as well as ocrelizumab for active multiple sclerosis. About 600 adults with relapsing or progressive MS will receive one of the two drugs. The main goal is to see if rituximab can prevent new brain lesions as effec…

This early-stage trial is testing a new way to give ocrelizumab (Ocrevus) for multiple sclerosis — as a simple shot under the skin instead of a long IV infusion. About 75 adults with MS will receive increasing doses to see if the new form is safe and tolerable. If it works, it co…

This early-stage trial tests a new treatment called KYV-101 for people with progressive multiple sclerosis (MS) that hasn't improved with standard treatments. KYV-101 is a CAR T-cell therapy made from a patient's own immune cells, designed to attack the cells causing inflammation…

This early-stage trial tests a new treatment called CC-97540, which uses a patient's own immune cells engineered to target and destroy harmful immune cells. The study includes 120 people with relapsing or progressive multiple sclerosis or refractory myasthenia gravis. The main go…

This Phase 3 trial is testing whether a higher dose of the drug ocrelizumab (Ocrevus) can better slow disability progression in people with primary progressive multiple sclerosis (PPMS). About 769 adults with PPMS are receiving either the standard approved dose or a higher dose b…

This study is testing the drug ocrelizumab in 927 people with progressive multiple sclerosis (MS), a form of the disease that steadily worsens. Participants receive infusions every 24 weeks for about 4 years. The main goal is to see if the drug can stop or slow disability progres…

This early-stage study tests an experimental cell therapy called P-CD19CD20-ALLO1 in 60 adults with multiple sclerosis. The main goal is to see if it is safe and how the body handles it. Researchers will also measure how long the cells last and how they affect the immune system.

This study tests the drug ocrelizumab in 60 Chinese adults with two forms of multiple sclerosis (MS): relapsing MS and primary progressive MS. The goal is to see if it reduces relapses and controls disease activity. Participants receive ocrelizumab infusions, and researchers trac…

This phase 2a trial tests a nasal spray called foralumab in 54 people with non-active secondary progressive multiple sclerosis (SPMS). The spray contains an antibody that aims to calm overactive immune cells in the brain. Participants will receive either a low dose, a high dose, …

This study aimed to test a new treatment called CABA-201, a CAR T-cell therapy made from a patient's own immune cells, for people with multiple sclerosis (MS). The goal was to see if it was safe and could control the disease by targeting and resetting the immune system. However, …

This phase 3 trial tests whether the oral drug masitinib can slow disability worsening in people with progressive multiple sclerosis who do not have relapses. About 800 participants will receive either masitinib or a placebo for 96 weeks. The main goal is to see if masitinib dela…

This study tests whether N-acetyl cysteine (NAC), a supplement, can protect the brain in people with progressive multiple sclerosis (MS). About 98 adults with primary or secondary progressive MS will receive either NAC or a placebo for 15 months. Researchers will measure brain sh…

This early-phase trial tests whether a patient's own bone marrow stem cells, injected into the spinal fluid, can repair nerve damage caused by progressive multiple sclerosis. The study involves 18 adults with secondary or primary progressive MS. Researchers will measure changes i…

This phase 3 trial tests whether ocrelizumab (Ocrevus) can slow disability progression in adults with primary progressive multiple sclerosis (PPMS). Over 1,000 participants receive either the drug or a placebo. The main goal is to see if the drug delays worsening of hand function…

This study aimed to test whether stem cells from amniotic fluid, injected into the spinal fluid, could safely help people with progressive multiple sclerosis (MS). The trial was designed for adults aged 18–60 with primary or secondary progressive MS. However, the study was withdr…

This program provides access to siponimod, a medication that helps control active secondary progressive multiple sclerosis (SPMS). It is for adult patients who have no satisfactory treatment options. Doctors can request the drug for eligible patients through a compassionate use p…

This study looks at people with relapsing-remitting multiple sclerosis who switched from the drug MabThera to a similar, lower-cost medicine called Rixathon. Researchers want to see if the switch changes signs of nerve damage, new brain lesions, relapses, or disability. They will…

This study looks at whether improving diet quality and reducing calories can help physical function, thinking, pain, fatigue, mood, and anxiety in 100 adults with relapsing-remitting or secondary progressive multiple sclerosis. Participants receive prepared meals and behavioral s…

This early-stage study tests whether a novel light therapy, designed to reset the body's internal clock, is safe and can reduce fatigue in people with progressive multiple sclerosis. Twenty participants will receive the light therapy while researchers monitor side effects and mea…

Researchers are sequencing the gut microbiomes of people with a wide range of conditions, from autism and Alzheimer's to Crohn's disease and multiple sclerosis, to see whether bacterial patterns differ by disease. The study also enrolls healthy participants for comparison. By mat…

This observational study follows about 2,400 people with relapsing-remitting multiple sclerosis (MS) across Germany for up to six years. It asks whether loss of volume in the thalamus—a deep brain region—tracks with worsening disability, measured by the EDSS scale. Using standard…

This study looks at whether combining a special breathing technique (called acute intermittent hypoxia, or AIH) with mild electrical stimulation of leg muscles can boost brain-to-muscle signals in people with relapsing forms of multiple sclerosis. About 40 participants will have …
