A new artificial intelligence (AI) algorithm could help identify people at risk of developing multiple sclerosis (MS). “Our model’s performance suggests that AI-based prediction models could identify the risk for multiple sclerosis years before neurological symptoms appear,” Raj Gopalan, MD, a scientist at Siemens Healthineers, Tarrytown, New York, said…

The Committee for Medicinal Products for Human Use (CHMP), an arm of the European Medicines Agency, has recommended that PB006, a biosimilar version of Tysabri (natalizumab), be approved to treat adults with highly active relapsing-remitting multiple sclerosis (RRMS). The recommendation comes about a year after the regulatory agency…

In multiple sclerosis (MS), inflammation leads to less energy production in nerve fibers by reducing the levels of enzymes in a key molecular pathway, called the TCA cycle, that cells use to generate energy, a new study shows. These findings imply that boosting activity of the TCA cycle might…

Synaptogenix is teaming up with Cleveland Clinic for a Phase 1 clinical trial involving people with multiple sclerosis (MS) that will test the company’s lead candidate, bryostatin-1 — a therapy designed to prevent cognitive deficits in MS patients. “We are moving forward with our clinical development plans for…

A first-of-its-kind study is aiming to determine whether older adults with multiple sclerosis (MS) can safely stop taking disease-modifying therapies, also known as disease-modifying agents (DMAs). The project is being led by scientists at the new P-HOPER Center, officially the Population Health Outcomes and Pharmacoepidemiology Education and Research…

With a planned merger in the works, Frequency Therapeutics is no longer advancing its remyelination therapies for multiple sclerosis (MS), and instead is exploring “strategic alternatives for the program,” the company has announced. The regenerative medicine company, which had aimed to develop a new approach to treating MS…

Since their launch in the 2010s, the use of oral disease-modifying treatments (DMTs) for multiple sclerosis (MS) has increased substantially, while injectable DMTs have become less popular, according to a study based on U.S. commercial health insurance data. “While two injectable therapies known as platform injectables, were once the…

A new formulation of Ocrevus (ocrelizumab), given as a 10-minute under-the-skin injection, was comparable to the approved intravenous version of the therapy in people with multiple sclerosis (MS), according to top-line results from a Phase 3 clinical trial. The medication’s developer, Roche, is planning to submit data from…

Inflammation in the membranes around the brain may trigger an inflammatory response that can spread into nearby brain tissue, a new study in a mouse model of multiple sclerosis (MS) shows. Researchers say these findings may help to advance scientists’ understanding of the mechanisms that underlie brain damage in…

The biopharmaceutical company Imcyse has signed on to a new project that aims to use artificial intelligence (AI) to develop tools that can be used to better track the progression of multiple sclerosis (MS). The project’s goal is to help guide treatment decisions for MS patients. Called Clinical…

Treatment with estriol, a hormone that’s produced during pregnancy, reduced disease severity and promoted myelin repair in the cortex — a key brain region affected in multiple sclerosis (MS) — in a mouse model of the disease. Those are the main findings of the study, “Neuroprotection in cerebral…

The PoNS device — officially the Portable Neuromodulation Stimulator, designed to help improve walking ability in people with multiple sclerosis (MS) — has been granted the accreditation needed for Medicare and Medicaid coverage in the U.S., according to Helius Medical Technologies, which makes the device. That designation, called…

Ocrevus (ocrelizumab) appears to be more effective than rituximab at reducing relapse activity in people with relapsing-remitting multiple sclerosis (RRMS), but disability progression outcomes are comparable between the therapies, an observational study of patients reported. “Study findings suggest that the effectiveness of rituximab on MS relapses was…

It’s been three decades since the first treatment for multiple sclerosis (MS) was approved. In that time, the field has made substantial advances — including the approval of over two dozen medications — but there’s still a long way to go to improve care for progressive forms of…

The protein DDX39B is a master regulator of immune tolerance, or the immune system’s ability to distinguish self from potentially harmful nonself molecules, and helps to control the development of immune cells that are key for this process, a new study shows. Findings suggest that activating DDX39B with small molecules…

For people with multiple sclerosis (MS), all forms of exercise are likely to be beneficial for physical fitness, but certain forms of exercise may be better than others at improving specific measures of fitness, according to a review of multiple clinical trials. Results suggest that resistance training — pushing…

Disease-associated inflammatory activity of microglia — a type of immune cell with a central role in the development of multiple sclerosis (MS) — is driven in part by molecular mechanisms that are activated when microglia try to clear the corpses of dead myelin-making cells. That’s according to a new…

People with relapsing multiple sclerosis (MS) who experienced disease activity while on oral therapies had less disease activity after switching to Kesimpta (ofatumumab), according to an analysis of data from the Phase 3 ARTIOS clinical trial.
