Aubagio (teriflunomide) can significantly reduce the risk of developing multiple sclerosis (MS) among adults with signs of MS-like brain damage who don’t yet have any disease symptoms, according to findings from a clinical trial. The results were presented earlier this year at the American Academy of Neurology…

Researchers have shed new light on the molecular mechanisms that help immune cells get into the brain to drive inflammation in multiple sclerosis (MS). Two proteins called MMP-9 and MMP-2 were found to break down some components of the barrier that keeps immune cells out of the brain, helping…

People who experience a first attack of multiple sclerosis (MS)-like disease are less likely to experience long-term disability progression if they start  treatment within the first few months, a new study reports. “When it comes to MS treatment, the earlier the better,” Alvaro Cobo-Calvo, MD, PhD, co-author of the…

A higher quality diet is associated with reductions in certain types of brain lesions in multiple sclerosis (MS), but no link was seen between a good diet and the risk of MS relapses or disability progression, a new study from Australia indicates. The study, “Higher…

Immune cells in the skull’s bone marrow show distinct molecular profiles from those of other bones throughout the body, and they may provide critical clues into how immune cells drive inflammation in neurological disorders like multiple sclerosis (MS) a study reports. “These findings carry profound implications, suggesting a far…

An antibody biomarker may help to distinguish people with a disease that resembles multiple sclerosis (MS), but may actually be its own clinical disorder, according to a new study. The biomarker was present in about 1% of MS patients and in 6% of those with a related demyelinating condition…

A new imaging technique was able to detect inflammation in a mouse model of multiple sclerosis (MS) before disease symptoms appeared, and to monitor the animals’ responses to treatment, a study reports. “With this new non-invasive imaging approach, we can detect toxic inflammation that could help us better understand…

Estimates of the prevalence of sexual dysfunction with multiple sclerosis (MS), as well of its risk factors, differ depending on the specific cutoffs used to assess sexual health on a standardized test, a study highlights. Regardless of the cutoff given, however, findings suggest that patients with poorer cognition tend…

In people with relapsing forms of multiple sclerosis (MS), relapses that occur in the first few years after the disease develops have a strong impact on rates of disability worsening — but after about 2.5 years, more relapses don’t consistently result in a greater worsening of disability, according to…

Pro-inflammatory immune cells that can target the brain may be activated in a specific region of the intestine by certain gut bacteria before migrating to the brain, according to a new study done in mice. Researchers say these findings provide a proof of concept for how some immune cells may…

Octave Bioscience has raised $30 million in financing to help accelerate commercialization efforts for its precision care program for people with multiple sclerosis (MS). “We have made significant progress in deploying our solution for multiple sclerosis patients,” William Hagstrom, founder and CEO of Octave, said in a…

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.
