Know its been approved for its opening day in March. If anyone goes on it, will you contact me either on the post or by PM and let me know what the "going" price is with insurance. I can't find it anywhere on Medicare D formulary lists so don't have a clue and don't want to switch programs until I know. I have just finished my first year on Tysabri and want to consider options for later but they won't give you prices until you have switched.......grrr
