CAMBRIDGE, Mass.--(BUSINESS WIRE)--Xanthus Pharmaceuticals, Inc. presented preclinical results from the Company’s FLT3 autoimmune program that describe a novel mechanism of action for achieving prolonged disease attenuation in an animal model for multiple sclerosis (MS). The experiments showed that Symadex™, the lead compound from Xanthus’ FLT3 autoimmune program, directly targets macrophages and monocytes, key cells responsible for driving the autoimmune response. Stephen J. Karlik, Ph.D., Professor of Diagnostic Radiology at the University of Western Ontario, London, Ontario, described these findings in an oral presentation at the 23rd Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) in Prague, Czech Republic.
