AI Technical Summary
Current methods for diagnosing and treating multiple sclerosis (MS) are inadequate in accurately identifying disease progression and determining effective treatment options, particularly due to the lack of reliable biomarkers for monitoring and prognosis.
Detection of biomarkers such as CXCL13, CXCL10, CD27, NEFL, CCL4, and CCL3 in cerebrospinal fluid, combined with the administration of tolebrutinib and potentially other therapies like anti-CD20 therapy, to provide precise diagnostic and therapeutic strategies for MS.
Enables accurate monitoring of MS progression and personalized treatment options by identifying specific biomarkers in CSF, thereby improving diagnostic accuracy and therapeutic efficacy.
