I have a very mixed reaction to this news - withholding this drug directly affects many people, including a few I know personally, who see this as a 2nd or 3rd line treatment, having failed on others. I have been on record as to how Campath/Lemtrada has been groomed to create huge profits for Genzyme/Sanofi.
In this case I do wish the FDA had approved Lemtrada, and left the final INFORMED decision up to the person with MS and their medical team.
