MS Trial Alert: Investigators Recruiting for Phase 3 Trial of Experimental Tolebrutinib in Primary Progressive MS
December 14, 2020
SUMMARY: Investigators in the U.S. and abroad are recruiting 1440 people with primary progressive MS for a study comparing investigational oral tolebrutinib with placebo. This study – also called PERSEUS – is sponsored by Sanofi .
DETAILS
Rationale: Tolebrutinib inhibits an enzyme called “Bruton’s tyrosine kinase,” reducing the activation of B cells, which are immune cells that play a role in the response that affects the brain and spinal cord in MS. Tolebrutinib also penetrates the brain and spinal cord and inhibits immune cells in the brain called microglia, which have been linked to MS progression. Tolebrutinib is one of several “BTK” inhibitors being tested in the MS pipeline.
Eligibility and Details: Participants should be 18 to 60 years old, and diagnosed with
primary progressive MS.
Participants will be randomly assigned to once daily treatment with either tolebrutinib or a placebo for a treatment duration of 24-48 months. The primary outcome of both studies will compare how treatment affects the time it takes for disability to progress using the EDSS scale. Secondary outcomes include safety, walking speed, cognitive function, disease activity on MRI scans, quality of life, and laboratory biomarkers of immune and nervous system activity. The study involves up to 16 visits to the study site, and will involve MRI scans, blood draws, clinical exams, and questionnaires.
Please note: This study requires in-person visits to the study site. Precautions are being taken to reduce the on-site risks of exposure to COVID-19.

Multiple sclerosis is an unpredictable disease of the central nervous system. Currently there is no cure. Symptoms vary from person to person and may include disabling fatigue, mobility challenges, cognitive changes, and vision issues. An estimated 1 million people live with MS in the United States. Early diagnosis and treatment are critical to minimize disability. Significant progress is being made to achieve a world free of MS.
The National MS Society, founded in 1946, is the global leader of a growing movement dedicated to creating a world free of MS. The Society funds cutting-edge research for a cure, drives change through advocacy and provides programs and services to help people affected by MS live their best lives.
