In people with multiple sclerosis (MS), lesions that get slowly bigger over time, potentially due to chronic inflammation, are associated with more myelin loss throughout the brain, a study found. Loss of myelin was observed in these slowly expanding lesions, in other types of lesions, and also in regions…

Note: This story was updated March 6, 2025, to clarify the specific disability measures and results assessed in each trial. Sanofi’s experimental BTK inhibitor tolebrutinib may be more effective at reducing the risk of disability accumulation in people with multiple sclerosis (MS) who have evidence of paramagnetic…

Treatment with Ocrevus (ocrelizumab) may have a beneficial effect on paramagnetic rim lesions — known as PRL, these are a type of chronic inflammatory lesion — in people with multiple sclerosis (MS), according to a newly shared analysis. PRLs, a form of nerve damage seen in MS, have…

The presence of paramagnetic rim lesions (PRLs), which represent areas of damage in the brain and spinal cord with chronic active inflammation, may help identify people with multiple sclerosis (MS) who are more likely to have cognitive decline over time. That’s according to four-year data presented by Hannah Schwartz,…

A more pro-inflammatory diet is associated with a higher risk of relapses and more inflammatory brain lesions for multiple sclerosis (MS) patients in the years following their first disease attack, according to a recent study. However, dietary intake did not impact disability progression or the volume of lesions with…

Smoking is associated with lower brain volume, more brain lesions, and greater disability and attention deficits among people with relapsing-remitting multiple sclerosis (RRMS) after 10 years, according to a study in Norway. “The findings imply that patients should be advised and offered aid in smoking cessation shortly after diagnosis, to…

An MRI technique called quantitative susceptibility mapping (QSM) can be used to accurately identify remyelinated brain lesions in people with multiple sclerosis (MS), a research team has discovered. Remyelinated lesions are those in which the myelin sheath — the protective coating around nerve fibers that is progressively lost…

Among people with nervous system damage indicative of multiple sclerosis (MS), but who don’t yet have the disease — a condition known as radiologically isolated syndrome or RIS — the risk of progressing to full-fledged MS is higher for those who are younger, have spinal cord lesions, and have…

Nerve tissue scars associated with multiple sclerosis (MS) show marked differences from those of similar neurodegenerative disorders, according to a recent study. MS-associated inflammation causes brain and spinal cord lesions (nerve tissue scarring) that often are bigger and last longer than those of two other demyelinating diseases: myelin oligodendrocyte…

Mavenclad (cladribine) reduces the number and volume of lesions in patients at risk of multiple sclerosis (MS) after a first clinical demyelinating event, a study based on Phase 3 trial data found. A demyelinating event occurs when myelin — the protective coating around nerve fibers — experiences damage; this…

Asymptomatic damage to spinal nerves occurs even in clinically stable cases of multiple sclerosis (MS) and carries an increased risk for further lesions, a recent study suggests. Although a firm link between the asymptomatic loss of myelin in the spine and worsening disability remains to be found, this work…

A novel medication targeting the protein folate receptor-beta (FR-beta) decreased inflammation and brain damage in a rat model of multiple sclerosis (MS). The findings were published in the Journal of Neuroinflammation, in the study “Efficacy and tolerability of folate-aminopterin therapy in a rat focal model of…

Studied for the first time, Aubagio (teriflunomide) slowed the loss of cortical grey matter and whole-brain volume in people with clinically isolated syndrome (CIS) during two years of therapy, a study found. The treatment was especially effective in those without brain lesions before treatment.

Adults with active relapsing-remitting multiple sclerosis (RRMS) treated with Tysabri (natalizumab) had fewer new and accumulated lesions, and a lower relapse rate than those treated with Gilenya (fingolimod) for 24 weeks, according to…

Before signs of neurodegeneration in the brain and spinal cord are evident in mice with experimental autoimmune encephalomyelitis (EAE) — which resembles human multiple sclerosis (MS) — signs can first be found in the network of nerves innervating the gastrointestinal (GI) tract, a study reports. Additional research is needed…

Low doses of rituximab, an anti-inflammatory medication used off-label to treat multiple sclerosis (MS), are safer and as effective as higher doses at reducing the frequency of relapses and the number of MS lesions, a clinical study shows. The study findings were presented at MSVirtual2020 by Luciana…

Immunic Therapeutics‘s IMU-838, a selective immune system modulator, can safely lower the number of brain lesions in people with relapsing-remitting multiple sclerosis (RRMS), top-line Phase 2 clinical trial data suggest. Findings show the trial met its primary goal with statistical significance — a reduction in active lesions (gadolinium…

More than half of people with brain imaging changes akin to multiple sclerosis (MS) go on to develop the disease within 10 years, a global study of those with radiologically isolated syndrome reported. Progression to MS appears to be more likely in those who are younger, have spinal…

Biogen has released new data on several of its therapies for multiple sclerosis (MS), including Vumerity (diroximel fumarate), Tecfidera (dimethyl fumarate), and Tysabri (natalizumab). The data — six presentations — originally were to be presented at the 2020 annual conference of the American…

In the brains of people with advanced multiple sclerosis (MS), memory immune cells reside in the brain tissue rather than entering through the bloodstream, a new study suggests. The study, “Tissue-resident memory T cells invade the brain parenchyma in multiple sclerosis white matter lesions,” was published…

The investigational anti-CD20 antibody ublituximab effectively depletes B-cells in people with relapsing forms of multiple sclerosis (MS), reducing the appearance of brain lesions and the risk of relapses, a study into clinical trial results suggests. Findings further suggest that the…

Janssen has submitted an application to the U.S. Food and Drug Administration (FDA) asking for ponesimod to be approved as an oral treatment for adults with relapsing multiple sclerosis (MS). Ponesimod, formerly ACT-128800, is an experimental treatment that targets the protein sphingosine-1-phosphate…

Multiple sclerosis (MS) patients with depression are more likely to have worsening neurological function compared with those who do not have the mood disorder, results from a real-world study show. The findings were presented Feb. 27 by Jenny Feng, MD, in an oral presentation — titled “…

Using brain tissue from people with multiple sclerosis (MS) and mouse models of MS, scientists identified a key pathway that drives astrocytes to promote inflammation in the brain and spinal cord. The study, “MAFG-driven astrocytes promote CNS inflammation” published in the journal Nature, uncovered potential therapeutic targets that may be…

An magnetic resonance imaging (MRI) scan can be an odd experience for those who have never had one before. Knowing what to expect beforehand can calm the nerves, so this week, I’m sharing what my first MRI was like. For people with multiple sclerosis (MS), frequent MRI scans are…

The experimental BTK inhibitor SAR442168 showed an acceptable safety profile and met its primary endpoint — a significant reduction in the number of new lesions visible on a brain imaging scan — in a Phase 2 trial in people with multiple sclerosis (MS), study results show. SAR442168,…

With the help of 7 Tesla magnetic resonance imaging (MRI), investigators discovered that leptomeningeal enhancement — a radiographic finding indicative of brain inflammation — is more common than previously thought in people with relapsing-remitting multiple sclerosis (RRMS), and is tied to lesions in specific regions of the brain.

Interferon therapy (brand names Avonex, Betaseron, and others) is more effective than glatiramer acetate (sold as Copaxone, Glatopa and other generics) for reducing relapses…

A protein known as nuclear factor I-A (NFIA) is key for spinal cord repair and timely remyelination by astrocytes — the most abundant cells in the brain and first responders to sites of injury, findings in a mouse model of multiple sclerosis (MS) suggest. In brain lesions, NFIA is…

Actelion‘s ponesimod, an investigational oral treatment, is superior to Sanofi‘s Aubagio (teriflunomide) in lessening the frequency of relapses and easing fatigue symptoms in adults with active, relapsing multiple sclerosis (MS), results of the OPTIMUM trial show.
