Tolebrutinib, a Brain-penetrant Bruton's Tyrosine Kinase Inhibitor, for the Modulation of Chronically Inflamed White Matter Lesions in Multiple Sclerosis
NCT04742400 · View on ClinicalTrials.gov ↗
Study Summary
Background: Some multiple sclerosis (MS) lesions stay inflamed for very long periods of time. This type of inflammation is not affected by any MS medications. These lesions can lead to slow worsening of MS symptoms. Researchers want to see if a new drug can help. Objective: To see if tolebrutinib can help clear inflammation in MS brain lesions. Eligibility: Adults ages 18 and older with MS who are on an anti-CD20 therapy. Design: Participants will be screened under protocol #89-N-0045. Participants will have a medical history. They will have physical and neurological exams. They will have blood and urine tests. The progression of their MS will be assessed. Participants will have MRIs of the brain. The MRI scanner is shaped like a cylinder. It uses a magnetic field and radio waves to take pictures of the body. During the MRIs, participants will lie on a table that slides in and out of the scanner. Soft padding or a coil will be placed around their head. Participants may have electrocardiograms to measure the heart s electrical activity. Participants may have lumbar punctures ( spinal taps ). A small needle will be inserted into the spinal canal in the lower back. Fluid will be collected. Some participants will take tolebrutinib pills by mouth once a day for at least 96 weeks. They will stop their anti-CD20 therapy. They will have at least 10 study visits. Some participants will not take tolebrutinib. They will stay on their anti-CD20 therapy. They will have 5 study visits. Participation will last at least 96 weeks.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04742400
The ClinicalTrials.gov registry entry for NCT04742400 describes a study currently listed as active not recruiting. It is categorized as Phase 2, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 12 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Neurological Disorders and Stroke (NINDS), which has 339 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Multiple Sclerosis appearing as the primary indexed condition, and to 2 interventions — of which tolebrutinib 60mg is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04742400 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
