Sorry, I just read your profile. I understand that you had a first round of alemtuzumab some years ago (it’s a good drug but which came with second autoimmunity like you know…). Did you have only one round of it? Normally, it is given for 2 (separated by one year between them) or even 3 rounds when needed.
Do you have relapses in the last years? Do you have annual MRI?
