Vumerity Approved for RRMS in European Union

The oral medication Vumerity (diroximel fumarate) has been approved by the European Commission to treat adults with relapsing-remitting multiple sclerosis (RRMS). “This approval is a significant step forward in improving treatment adherence for people living with relapsing MS, which can make a meaningful difference on treatment…

sNfL Levels Linked to Relapse-free Disability Progression, Move to SPMS

Measuring levels of the protein serum neurofilament light chain (NfL) can help to identify people with relapsing-remitting multiple sclerosis (RRMS) at higher risk of relapse-free disability progression or conversion to secondary-progressive disease, according to a study from Germany. The study, “NfL predicts relapse-free progression in a longitudinal…

Study Sheds Light on How Tecfidera Kills Immune Cells

The multiple sclerosis (MS) treatment Tecfidera (dimethyl fumarate) triggers immune cell death by interacting with a protein called Keap-1, a new study reveals. The study, “Wdr1 and cofilin are necessary mediators of immune-cell-specific apoptosis triggered by Tecfidera,” was published in Nature Communications. Tecfidera is widely…

Ocrevus Still Top Therapy for Progressive MS Forms, Report Finds

Ocrevus (ocrelizumab) continues to be the most commonly prescribed therapy for progressive forms of multiple sclerosis (MS), including primary progressive MS (PPMS) and secondary progressive MS (SPMS), according to an analysis from the market intelligence firm Spherix Global Insights. However, other therapies are “gaining traction” among…

Canadians Prepare for 2021 Women Against MS Gala

This year’s Women Against Multiple Sclerosis (WAMS) Gala, which aims to raise funds for multiple sclerosis (MS) research, will take place Nov. 5. In order to keep participants safe in the setting of the ongoing pandemic, the MS Society of Canada‘s initiative will feature three events held…

Cold Eases Inflammation, Disease Severity in MS Mouse Model

Colder ambient temperatures may ease the inflammation that drives multiple sclerosis (MS), early research in a mouse model suggests. Animals whose environment for two weeks was set at 10 C (about 50 F) had a “pronounced attenuation” of disease severity and other benefits compared with those kept at a…

Hydroxychloroquine Shows Potential to Treat PPMS in Phase 2 Trial

Treatment with hydroxychloroquine, an anti-malaria medication, appeared to help slow disability progression among people with primary-progressive multiple sclerosis (PPMS) in a small, proof-of-concept clinical trial. Hydroxychloroquine “is a promising treatment candidate for PPMS and should be investigated further in randomized controlled clinical trials,” its researchers wrote. Results of the study…

Oct. 4 Online Conference Offers Latest Insights Into Progressive MS

An upcoming conference focused on progressive multiple sclerosis (MS) will offer the latest insights about the underlying biology of the disease, and treatment and clinical strategies in development. The one-day conference, “Emerging Research & Trial Strategies for Progressive Multiple Sclerosis,” is taking place virtually on Oct. 4,and is…

Cognitive Rehab ‘Effective, Low-risk’ in Treating Difficulties Due to MS

Cognitive rehabilitation is an effective therapy for cognitive problems brought on by multiple sclerosis (MS), a review study highlights. “Clinicians should consider this low-cost, low-risk, yet effective treatment approach for their patients,” its researchers wrote. The study, “Neurological update: cognitive rehabilitation in multiple sclerosis,” was published…

Cancer Researchers’ Discovery May Benefit MS Studies

In an unexpected discovery, scientists working to understand the biological underpinnings of brain tumors found that increasing the activity of a protein receptor called PDGFRA reduces the production of myelin — the fatty coating that is lost in multiple sclerosis (MS) — in the nervous system. “We saw that…

Tecfidera May Reduce Relapse Rate More Than Other RRMS Therapies

First-line treatment with Tecfidera (dimethyl fumarate) leads to a lower rate of relapses in people with relapsing-remitting multiple sclerosis (RRMS) than does treatment with Aubagio (teriflunomide) or injectable immunomodulators, according to an analysis of insurance data from France. “These data will be useful to feed into physician…

MS Tied to Increased Risk After Colorectal Cancer Diagnosis

People who develop colon cancer are more likely to die in the first year, from that cancer or other causes, if they also have multiple sclerosis (MS), a new study indicates. MS disability seems to contribute to this association. “These results warrant further investigation to determine what factors may…

Anti-CD20 Therapies Show Similar Safety, Efficacy in RRMS

Anti-CD20 antibody therapies that target B-cells are highly effective for reducing the risk of relapses in people with relapsing-remitting multiple sclerosis (RRMS), a new analysis confirms. The analysis did not find any significant differences in efficacy or safety among the anti-CD20 therapies currently approved to treat RRMS, though…
