Well...today is the neuro appointment where I'm going to give in and start the process to switch from Tysabri to Ocrevus. I've posted about this before because it seems like a Solomon's choice and I hate that that Ocrevus isn't a clearly better option. (I'm saying this because of the incidence of cancer during the trials, the low volume of patients in the trials, no one over 55 in the trials, and that it hasn't been out in the wild enough for anyone to say definitively what the PML risk is.) I'm JVC+ with a high index and have been on Tysabri for 5+ years so my risk of PML is in the higher category at least while on Tysabri. This has been weighing on me. The only viable option for me, if I want to stay on DMT, is Ocrevus.
I'm nervous about switching to be honest because of that one patient who switched from Tysabri to Ocrevus and got PML. It doesn't matter to me that they are blaming the PML on Tysabri...I'm freaked out because it happened at all!
