Vumerity Added to NHS of England for People With Active RRMS

The National Institute for Health and Care Excellence (NICE) has added oral Vumerity (diroximel fumarate), approved to treat relapsing-remitting multiple sclerosis (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 – 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…

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, “…

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) — an immunization often given to infants and small children in countries where TB is common — 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 – 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…

#ACTRIMS2022 – Cognitive Training Paired With tDCS Aids Patients

Electrically stimulating the brain while doing at-home cognitive training games can help to prevent a decline in cognition for people with multiple sclerosis (MS), particularly those with more advanced disability, a study indicates. “This could lead to a therapy that can remediate cognitive impairment, we just need to optimize”…

#ACTRIMS2022 – Tolebrutinib More Potent Than Other BTK Blockers

Tolebrutinib, an investigative inhibitor of Bruton’s tyrosine kinase (BTK) being developed by Sanofi to treat all forms of multiple sclerosis (MS), shows the potential to be more potent than other BTK inhibitors also in advanced clinical trials, scientists reported. The findings, based on preclinical data, were shared at the Americas…

#ACTRIMS2022 – Algorithm Predicts Relapse Risk Using EHR Data

Using a two-step machine learning strategy, researchers have developed an algorithm to predict the risk of multiple sclerosis (MS) relapse based on data gleaned from electronic health records. “The two-step machine learning model predicts a patient’s future one-year MS relapse risk with clinically actionable accuracy, comparable to other clinical…
