Diagnosing primary progressive MS difficult, despite guidelines

DiagnosingĀ primary progressive multiple sclerosis (PPMS) can be challenging, with obstacles ranging from ruling out other disorders to differentiating between PPMS and other types of multiple sclerosis (MS). These difficulties were highlighted in the study, “Real-world challenges in the diagnosis of primary progressive multiple sclerosis,” published…

Sugar molecule found to promote myelin repair in cell model

Treatment with polysialic acid, a sugar molecule naturally made in the body, may be a promising approach to boost myelin repair in people with multiple sclerosis (MS), according to a new study in lab-grown brain samples. Findings show that the molecule increased myelin repair, or remyelination, in the cell…

Octave raises $30M to speed commercialization of care program

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

AI model is able to predict MS risk years before disease onset

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…

Phase 1 trial of bryostatin-1 in MS expected by year’s end

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 ā€” a therapy designed to prevent cognitive deficits in MS patients. ā€œWe are moving forward with our clinical development plans for…

Can elderly MS patients safely stop treatment? Study aims to find out.

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 Korro Bio merger in works, Frequency stops program for MS

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…

Use of oral DMTs grew substantially since their launch: US study

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. ā€œWhile two injectable therapies known as platform injectables, were once the…

Pregnancy hormone estriol promotes myelin repair in MS mice

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

PoNS device wins accreditation needed to be covered by Medicare

The PoNS device ā€” officially the Portable Neuromodulation Stimulator, designed to help improve walking ability in people with multiple sclerosis (MS) ā€” 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 appears to be better than rituximab at preventing MS relapses

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…
