DMT: Ocrelizumab

Ocrevus was the most recent medication brought up to me when the great Dr. K last talked about finding a Tysabri alternative. Once again, Tysabri is working absolutely great for me, and I’m in no hurry to switch off it. But given all the safety issues, It’d be remiss to not even consider an alternative. The great Dr. K hasn’t yet given me the efficacy rate of Ocrevus (or I forgot), probably as it’s so new, however he did mention that it is proving very effective for those who take it. Something to consider, but I have that old school ‘if it ain’t broke, don’t fix it’ attitude (unless it’s involving technology).

Ok, so what is Ocrevus? It is a humanized anti-CD20 monoclonal antibody. Yeah, what? Again? I don’t make this stuff up. I’m not that familiar with it, but here is what I take. Ocrevus binds to immune B cells via the CD20 receptor and kills them.  Wait? That can’t be good? Except when your own immune system is attacking your CNS, it’s probably a very good thing. And it is proably why I saw all those mentions of being immunosuppresed  for a bit while starting it.

As for frequency, that is where this drug seems to shine.  You only need to receive Ocrevus twice-a-year. Every six months sounds rather nice. I’ve mentioned before, many times actually, my needle anxiety and this would make for four less infusions per year.  Better than the six infusions per year, which isn’t a problem for me – anymore at least. The post-infusion danger zone seems to be longer on Ocrevus (24 hours observation) versus Tysabri (one hour observation). On Tysabri, they have me sit in the ambulatory infusion center room for an additional hour to insure I have no reaction (should happen for everyone on Tysabri, unless your nuero says you don’t have to be observed). With Ocrevus, I imagine they send you home on self-watch for reaction symptoms after a bit of observation. Though, I am not yet sure if they keep you for a period after infusion.

Ocrevus does carry the same brain destroying risk as Tysabri: PML. Since it also has a PML risk, I will stay on the miracle MS drug Tysabri for as long as possible. It is working great for me, I barely realize I have MS because of it. But if I ever need to switch to another medication, it will probably be Ocrevus. At this point in time anyway.
