Multiplex proteomic biomarker panels are redefining how we understand and monitor multiple sclerosis (MS) by capturing interconnected pathways in a single sample. Hear from Dr. Raphael Schneider as he explores how these tools could inform prognosis, risk stratification, and clinical trial design, which he spoke about at the 2026 ACTRIMS Forum. Dr. Schneider is a neurologist and researcher at the BARLO MS Centre at St. Michael’s Hospital as well as an Assistant Professor and the Elizabeth S. Barford Early Career Professor in Multiple Sclerosis in the Department of Medicine at the University of Toronto.
