Amiselimod (MT-1303) is a selective sphingosine 1-phosphate 1 (S1P1 ) receptor modulator which is currently being developed for the treatment of various autoimmune diseases. Unlike some other S1P receptor modulators, amiselimod seemed to show a favourable cardiac safety profile in preclinical, phase I and II studies. Amiselimod may be potentially useful for treatment of multiple sclerosis; inflammatory diseases; autoimmune diseases; psoriasis and inflammatory bowel diseases. Amiselimod is currently being developed by Mitsubishi Tanabe Pharma Corporation.
