More, earlier damage seen in primary progressive MS vs SPMS

People with primary progressive multiple sclerosis (MS) may experience more severe inflammatory activity and nerve damage early on in the course of their disease as compared with individuals who have secondary progressive MS, a new study indicates. The results also suggest that primary progressive MS patients tend to have…

Treatments with electrical nerve stimulation ease pain in small trial

Transcutaneous electrical nerve stimulation (TENS) and interferential currents (IFC) — both interventions apply electrical stimulation through electrodes placed on the skin — can help to ease pain in people with multiple sclerosis (MS), according to results from a small clinical trial. Results suggested that, while both treatments can reduce…

ACTRIMS 2023: TG aims to make Briumvi accessible to patients

Briumvi (ublituximab-xiiy) recently became the third anti-CD20 monoclonal antibody to be approved by the U.S. Food and Drug Administration (FDA) as a treatment for relapsing forms of multiple sclerosis (MS). TG Therapeutics, the therapy’s developer, is now aiming to make Briumvi the most accessible therapy in its…

ACTRIMS 2023: CNM-Au8 bound for Phase 3 testing after positive data

Treatment with the experimental oral suspension therapy CNM-Au8 led to improvements in measures of vision, cognitive and motor function, and brain health for people with multiple sclerosis (MS), according to data from the proof-of-concept VISIONARY-MS trial. Bolstered by these positive results, Clene Nanomedicine is planning to launch a…

Omega-3 fatty acid reduced disease severity in MS mouse model

Treatment with docosahexaenoyl ethanolamide (DHEA), an omega-3 fatty acid found in fish oil, reduced inflammation and disease severity in a mouse model of multiple sclerosis (MS). These findings suggest that “an increase of omega-3 consumption may be beneficial to patients diagnosed with MS,” researchers said. “We believe our findings…

CNM-Au8 preserves white matter in RRMS patients’ brains: Phase 2 trial

Treatment with CNM-Au8, an experimental oral liquid therapy, led to statistically significant improvements in the health of connections between brain regions for people with stable relapsing-remitting multiple sclerosis (RRMS). That’s according to new MRI data from the Phase 2 VISIONARY-MS trial (NCT03536559), which tested CNM-Au8 against a placebo in…

‘Mini-brain’ models point to poorer oligodendrocyte growth in PPMS

Using stem cells derived from people with multiple sclerosis (MS), researchers developed cerebral organoids, or “mini-brains,” to better study the cellular and molecular mechanisms leading to the neurodegenerative disorder. Initial analysis showed that patient-derived stem cells, especially those from people with primary progressive MS (PPMS), tend to be…

Berberine, plant compound, eases disease severity in MS mouse model

Treatment with berberine, a compound found in many plants, eased disease severity and showed anti-inflammatory effects in a mouse model of multiple sclerosis (MS), a new study reports. “These results confirmed that treatment with berberine efficiently improved the disease in the animal model of MS,” the researchers wrote, noting…

Biosimilar Comparable in Safety, Efficacy to Tysabri in Phase 3 Trial

PB006, a biosimilar to Biogen’s approved treatment Tysabri (natalizumab), showed similar safety and efficacy as the original medication in people with relapsing-remitting MS (RRMS), according to data from a Phase 3 clinical trial. “The Antelope trial reported equivalence between [PB006 and Tysabri] treatment across efficacy, safety, and secondary…
