Imaging of Retina Can Help in Monitoring Nerve Cell Damage in MS

An imaging technique called optical coherence tomography (OCT) could be useful for monitoring nervous system damage in people with multiple sclerosis (MS), especially early on in the disease, a study in patients reports. The study, “Optical coherence tomography in multiple sclerosis: A 3-year prospective multicenter study,”…

National MS Society Funds 13 New Research Projects

The National MS Society has announced it is funding 13 new research projects that seek to better understand the risk factors involved in multiple sclerosis (MS) development and progression. The funding — nearly $7 million in total — also will go to “rescue” 22 MS-related research projects that…

Report: Tecfidera, Aubagio Preferred RRMS Treatments in Canada

Tecfidera (dimethyl fumarate) and Aubagio (teriflunomide) are the preferred disease-modifying treatments for managing relapsing-remitting multiple sclerosis (RRMS) in Canada, according to a report from Spherix Global Insights. The report was part of Spherix’s RealTime Dynamix: Multiple Sclerosis (Canada) service, which collects data on market trends of MS…

Worsening of Disability Evident in Older Patients Who Stop DMTs

While older multiple sclerosis (MS) patients whose conditions are stable commonly stop using disease-modifying therapies (DMTs), a study indicates this decision can shortly lead to a marked disease worsening in a substantial portion of them. “Our results raise important questions about the accepted practice of discontinuing medications once MS…

Some Cell Therapies Work by Dying, New Research Shows

Certain cell therapies that hold promise for treating autoimmune diseases like multiple sclerosis might work not because of the way the cells live in the body during treatment, but because of how they die. A better understanding of how these cell therapies work “is important in designing treatment protocols…

1st Patient Enrolled in ENSURE Trials of IMU-838 in RRMS

Immunic Therapeutics has enrolled the first participant in its Phase 3 ENSURE clinical trial program, which is testing the company’s investigational treatment IMU-838 (vidofludimus calcium) in people with relapsing-remitting multiple sclerosis (RRMS). “Enrollment of the first patient in ENSURE … marks an important inflection point for Immunic as we…

Cholesterol Made by Nerve Cells Repairs Myelin Damage in Mice

Cholesterol made by neurons is crucial for repairing long-term damage to the myelin sheath, the fatty coating around nerve fibers that is damaged in multiple sclerosis (MS), according to a new report based on experiments done on mice. The finding suggests that increasing neuronal cholesterol synthesis may be helpful…

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…
