#ACTRIMS2022 ā€“ Tolebrutinib More Potent Than Other BTK Blockers

Tolebrutinib, an investigative inhibitor of Brutonā€™s tyrosine kinase (BTK) being developed byĀ SanofiĀ to treat all forms ofĀ 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 ā€“ 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…

#ACTRIMS2022 ā€“ In New Mouse Model, Evobrutinib Shows Efficacy

Researchers developed a new mouse model that more closely captures a specific type of inflammation characteristic of progressive multiple sclerosis (MS) ā€” and found, in experiments, that treatment with an oral medicationĀ called evobrutinibĀ can lessen disease activity. This new mouse model may help scientists in MS to better study…

Eating Beans, Vegetables May Reduce MS Risk

Eating a lot of green leafy and other vegetables, beans, nuts and berries seems to significantly lower the likelihood of developing multiple sclerosis (MS), according to a study from Iran. The findings also suggest that the chances of developing the disease may be higher in people who eat more…

Vumerity Added to NHS of Scotland for People With Active RMMS

Note: An earlier version of this story stated the Scottish Medicines Consortium approved Vumerity for RRMS patients in that country. The consortium decides to add a medicine to Scotlandā€™s National Health Service; the MHRA approves treatments for England, Scotland, and Wales. The Scottish Medicines Consortium has approved adding the…

Atara, Fujifilm Enter Deal to Produce Cell Therapies

Atara Biotherapeutics has reached an agreement withĀ Fujifilm Diosynth Biotechnologies for the production of its cell therapy pipeline, including ATA188, an experimental therapy being investigated for the treatment of progressive multiple sclerosis (MS). Under the agreement, Fujifilm will acquire Ataraā€™s T-Cell Operations and Manufacturing (ATOM) facility in Thousand…

How Vitamin D Modulates Immune System Activity Detailed in Study

Vitamin D can influence the immune system’s tolerance to certain proteins by changing how DNA is packaged in specific immune cells called dendritic cells, according to a new study. Its findings could have implications for treating diseases like multiple sclerosis (MS) that are characterized by the immune system attacking…

Imaging Brain Metabolites May Help Diagnose, Monitor MS

A new imaging technique called magnetic resonance spectroscopic imaging, or MRSI, could be useful for diagnosing and monitoring multiple sclerosis (MS), according to a small study. “If confirmed in longitudinal clinical studies, this new neuroimaging technique could become a standard imaging tool for initial diagnosis, for disease progression and…

Study Probes Why Some Don’t Experience Placebo Effect

Differences in the physical architecture of the brain may explain why some people with multiple sclerosis (MS), but not others, experience a placebo effect, according to a new study. The results suggest that MS itself may make some individuals unable to experience the benefits of a placebo. “Our findings…
