New hope: Drug candidate that helps repair myelin in MS

Key Takeaway

A repurposed drug called bavisant helped protect nerves and supported myelin repair in multiple lab and mouse tests, making it a promising candidate to slow disability in MS.

What They Found

Researchers screened over 1,500 existing drugs by computer methods to see which might help rebuild myelin (the protective sheath around nerve fibers) and protect nerve cells. From that list they focused on about 273 drugs, then narrowed to 160 that looked likely safe, and finally found 32 that helped both myelin-producing cells and neurons in lab tests. One drug, bavisant, which blocks a specific histamine receptor (a protein that responds to a chemical called histamine), was tested more deeply in several mouse models that mimic MS damage. In those mouse experiments bavisant increased remyelination (the rebuilding of the myelin sheath) and reduced nerve damage after different kinds of injury. Tests also included human cells and a special mouse with human myelin cells, and bavisant showed benefit there too, supporting the idea it could work in people with MS.

Who Should Care and Why

People with MS and their caregivers should care because the main problem in progressive MS is loss of myelin and nerve damage, which current treatments do not reliably reverse; bavisant aims to help repair that damage. Think of myelin like insulation on electrical wires—if insulation is repaired, the wire works better; this drug seems to help the body rebuild that insulation. Neurologists and MS care teams will be interested because a therapy that promotes remyelination and neuroprotection could be added to existing treatments to better preserve function. Caregivers may notice this could mean fewer new symptoms or slower worsening over time if the results translate to people. People considering clinical trials might look for studies of bavisant as a possible new option focused on protecting nerves and restoring myelin rather than only reducing inflammation.

Important Considerations

These results come from computer screening, lab tests, and mouse models, not from human clinical trials, so we don’t yet know how safe or effective bavisant is in people with MS. Animal and cell model success does not always predict human benefit because human biology and disease course can be more complex. Future clinical trials are needed to confirm whether bavisant truly helps people with MS, what dose is safe, and who would benefit most.

Early Research Treatment Updates Clinical Trials

Whether you’ve recently been diagnosed with Multiple Sclerosis (MS) or are seeking to broaden your understanding of this complex, neurodegenerative disease, navigating the latest research can feel overwhelming. Studies published in respected medical journals like Science translational medicine often range from early-stage, exploratory work to advanced clinical trials. These evidence-based findings help shape new disease-modifying therapies, guide symptom management techniques, and deepen our knowledge of MS progression.

However, not all research is created equal. Some clinical research studies may have smaller sample sizes, evolving methodologies, or limitations that warrant careful interpretation. For a more comprehensive, accurate understanding, we recommend reviewing the original source material—accessible via the More Details section above—and consulting with healthcare professionals who specialize in MS care.

By presenting a wide range of MS-focused studies—spanning cutting-edge treatments, emerging therapies, and established best practices—we aim to empower patients, caregivers, and clinicians to stay informed and make well-informed decisions when managing Multiple Sclerosis.
