ECTRIMS 2023: Vidofludimus calcium lowers RRMS nerve damage

Six months of treatment with the experimental oral therapy vidofludimus calcium (IMU-838) led to significant reductions in a marker of nerve damage among people with relapsing-remitting multiple sclerosis (RRMS), according to a new analysis of data from a Phase 2 clinical trial. Previous data indicated the therapy significantly reduced…

Most disability worsening on Ocrevus not tied to relapses: Study

Among multiple sclerosis (MS) patients treated with Ocrevus (ocrelizumab), most of the disability worsening they experience is not associated with any relapse activity, according to an analysis of real-world data. “We present real-world data from our multiple sclerosis center underlining that in a typical population of relapsing MS…

Lemtrada controlled RRMS disease activity more than a decade

Over more than a decade of treatment with Lemtrada (alemtuzumab), relapse rates were low and about half of people with relapsing-remitting multiple sclerosis (RRMS) remained free of confirmed disability worsening, according to final results from the open-label TOPAZ clinical trial. “To our knowledge, this report represents the longest…

Neurologists share treatment preferences for older adults with MS

For older adults with multiple sclerosis (MS) who have highly active disease, most neurologists recommend starting treatment with a high-efficacy therapy, according to a survey study. Neurologists also generally agreed that patients with MS should continue on treatment into the latter decades of life, and that older MS patients…

Taking sugar molecule supplements may help ease inflammation in MS

Taking supplements of the sugar molecule N-acetylglucosamine, known as GlcNAc, was found to decrease markers of inflammation in people with multiple sclerosis (MS) in a small clinical trial. Moreover, nearly a third of trial participants reported less severe disability following a month of daily GlcNAc supplements. However, because this…

Is Aubagio still ethical to use as comparator in MS trials?

Noting that Aubagio (teriflunomide) continues to have “a robust impact on disability progression” in multiple sclerosis (MS) despite being eclipsed by newer MS treatments in trials, an international team of researchers are now arguing that it is, in fact, still ethical to use the older therapy as a…

Diagnosing primary progressive MS difficult, despite guidelines

Diagnosing primary progressive multiple sclerosis (PPMS) can be challenging, with obstacles ranging from ruling out other disorders to differentiating between PPMS and other types of multiple sclerosis (MS). These difficulties were highlighted in the study, “Real-world challenges in the diagnosis of primary progressive multiple sclerosis,” published…

Sugar molecule found to promote myelin repair in cell model

Treatment with polysialic acid, a sugar molecule naturally made in the body, may be a promising approach to boost myelin repair in people with multiple sclerosis (MS), according to a new study in lab-grown brain samples. Findings show that the molecule increased myelin repair, or remyelination, in the cell…
