It is being clinically tested on PPMSers at Johns Hopkins, my neuro is doing trial. I've always wanted to try it (maybe it's the old name - Fingolimod I like) My ex old neuro who moved away was in charge of trial until he moved and tried to get me in it. Now my new neuro is in charge but rejected me quickly (I am 6.5, you had to be 6.0. I really liked my ex-neuro, he was out of the box if you know what I mean. The new one is younger and a rule follower.
