Kesimpta (ofatumumab) may be more effective at reducing relapse rates than other disease-modifying therapies (DMTs) in Japanese adults with relapsing forms of multiple sclerosis (MS), according to a review of clinical trial data. Although the differences were not statistically significant, the study provided comparative evidence that may help…

Gilenya (fingolimod) and Tysabri (natalizumab) were more effective at lowering relapse rates in children with multiple sclerosis (MS) than interferon-beta, according to a recent meta-analysis. Findings like these can be leveraged for better clinical trial design, the researchers wrote. If used to determine “historical” relapse rates that…

Cannabis ‘Highly Effective’ Against MS Symptoms, Some Users Report I would’ve expected many users to report that cannabis has been highly effective at treating MS symptoms, not just some. But comments about this study on the MS News Today Facebook page indicate that people have mixed results. Even…

Tysabri (natalizumab) given every six weeks was found to be similarly effective as the standard four-week dosing schedule at stopping nervous system damage in people with relapsing-remitting multiple sclerosis (RRMS). That’s according to the full results of the Phase 3b NOVA clinical trial, which compared Tysabri dosing schedules…

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…

The majority of multiple sclerosis (MS) patients who stop taking Tysabri (natalizumab) before or when they become pregnant experience a disease relapse during pregnancy or shortly thereafter, according to a study out of Germany. In more than one out of every 10 cases, relapses were so severe that…

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…
