I had an appointment with my neurologist today and he gave me an update on this drug, also known as ocrelizumab. It supposed to be approved any day according to my dr, but there are questions about how the drug will be labelled and who will be able to get it. As I understand it, this has to do with the way the clinical trials were designed and the question about where SPMS fits into the spectrum of MS.
This does not mean people with SPMS won't be able to get the drug, it depends on the labeling and how your dr has classified you. My dr was curious himself to see how the label would read.
As for my condition, my dr saw very little change in 6 months by his testing, although I am aware of continued progression. I was told to "keep up the good work" - diet exercise, Ampyra, Biotin, etc. I guess I'll stick with it, as I think I'm doing pretty well compared to many others.
