Wotcha,
I was participating on a drug trial testing the efficacy of Tysabri in cases of SPMS. I just had a phone call from the clinic telling me that the trial has been cancelled with immediate effect. I do not know why, and presume that it is a commercial decision. This could mean a zillion different things. Rather than speculate (which can set hares running in all directions) please can you let me know if you have any info.
Cheers Mick
