All currently available therapeutic options for multiple sclerosis have to be administered parenterally. Several oral substances are currently in the late clinical development stage. One of them, FTY720 (also known as fingolimod) is highlighted in this review. The biological effects of FTY720 are presented as well as animal data and first clinical data from a phase II trial in multiple sclerosis patients. The effects of FTY720 are based on an innovative approach and apparently target several key elements in the pathogenesis of multiple sclerosis. The first clinical data with FTY720 show very promising results, with a relapse reduction of over 50% compared to placebo and an acceptable safety profile. These results currently await confirmation in two international phase III studies which are recruiting patients worldwide.
