Trial of Metformin-Clemastine Combo Enrolls First Patient

The first participant has been enrolled in a new clinical trial that is testing whether an antihistamine in combination with a diabetes medication might promote the repair of the myelin sheath in people with multiple sclerosis (MS). The trial’s first participant, Annabelle, was diagnosed with relapsing MS over a…

#AAN2022 ā€“ More Patients Given Ublituximab Relapse-free in Trials

More relapsingĀ multiple sclerosisĀ (MS) patients givenĀ ublituximabĀ remained relapse-free over the two-year long Phase 3 ULTIMATE clinical trials, compared to those givenĀ AubagioĀ (teriflunomide), new data show. “The prevention of relapses represents an important goal of disease-modifying therapy with the potential for a marked impact on the accumulation of disability,” Lawrence Steinman,…

Data Is Lacking on Safety of MS Treatments During Breastfeeding

There is minimal data available on the safety of most disease-modifying therapies for multiple sclerosis (MS) when used during breastfeeding, a new review indicates. The study “Disease-Modifying Drugs and Breastfeeding in Multiple Sclerosis: A Narrative Literature Review,” was published inĀ Frontiers in Neurology. Disease-modifying therapies, or DMTs,…

Equal DMT Use Found in Norway Despite Socioeconomic Status: Study

People newly diagnosed with multiple sclerosis (MS) in Norway have in recent years received disease-modifying therapies (DMTs) independent of their socioeconomic status, according to a new analysis. These findings do not support previous reports indicating that fewer DMTs are prescribed for the most socially deprived MS patients, the…

Vumerity Added to NHS of England for People With Active RRMS

The National Institute for Health and Care Excellence (NICE) has added oralĀ Vumerity (diroximel fumarate), approved to treatĀ relapsing-remitting multiple sclerosisĀ (RRMS) in the U.K., to the list of medications available through the public health program for England. Because the therapy has been recommended through a fast track appraisal process, Vumerity…

#AAN2022 ā€“ Ublituximab Bests Aubagio on Disability Measures

Ublituximab, an experimental therapy for relapsing multiple sclerosis (MS) patients, outperformed Aubagio on a number of disability-related outcomes in the ULTIMATE clinical trials, new data show. The findings were presented in a series of posters at the 2022 American Academy of Neurology (AAN) Annual Meeting, being held in…

No Link Between Herpes Infection and MS Risk in Genetic Study

Infection with the herpes simplex virus does not increase the risk of multiple sclerosis (MS), according to a new analysis based on genetic data. The study, ā€œMendelian Randomization Analysis Suggests No Associations of Herpes Simplex Virus Infections With Multiple Sclerosis,ā€ was published in Frontiers in…

STAT5 Protein Complex Implicated in MS Autoimmunity in Mice

A four-protein complex, or tetramer, of the protein STAT5 is involved in the development of multiple sclerosis (MS)-like autoimmune disease in mice, a new study shows. The findings point to this protein complex and its signaling pathway as a potential treatment in MS and other autoimmune conditions, scientists noted.

Scientists Review State of Cannabis Research in MS

Treatment with cannabis-based medications may ease muscle spasms, decrease pain, and aid in sleep for people with multiple sclerosis (MS), but more research is needed to evaluate the potential benefits of cannabis use. That is the finding of a team of U.S. researchers who published a review paper,Ā “…

MS Doctors, Nurses in UK Struggle With Marking Transition to SPMS

Among healthcare providers in the U.K., considerable variation exists in marking the transition from relapsing-remitting multiple sclerosis (RRMS) to secondary progressive multiple sclerosis (SPMS), a study based on interview responses reports. Neurologists and nurses with MS specialties also expressed a reluctance to label patients as having progressed to…

BCG Vaccine for TB Not Linked to MS Risk: Large Canadian Study

Getting the Bacillus Calmette-Guerin (BCG) vaccine to protect against tuberculosis (TB) ā€” an immunization often given to infants and small children in countries where TB is common ā€” does not decrease a person’s risk of developing multiple sclerosis (MS), according to a new study. “Within a large birth cohort…

Novantrone Lowers Relapses, Eases Disability in Highly Active RRMS

Initial treatment with Novantrone (mitoxantrone) can reduce the risk of relapses and worsening disability in people with highly active relapsing-remitting multiple sclerosis (RRMS), according to a 10-year study from France. “Our results support the short-term use of [Novantrone], followed by a maintenance therapy for patients with early highly…

Worsening Disability in Absence of Relapses ‘Underestimated’ in MS

A substantial amount of disability worsening happens independently of relapses in people with multiple sclerosis (MS), including those in earlier stages of relapsing-remitting disease, a study in a large patient database reported. While its findings “confirm relapses contribute to the accumulation of disability, primarily early in multiple sclerosis,” data…

#ACTRIMS2022 ā€“ Blood NfL Levels May Help Quantify Relapse Severity

Measuring levels of the neurofilament light chain (NfL) protein in blood may be a way to “quantify” relapse severity and predict future disability in people with relapsing-remitting multiple sclerosis (RRMS). “Higher [blood] NfL levels during periods of active inflammation predicted more [brain] atrophy,” researchers wrote in an abstract titled…
