MBP is not yet out, is it? That certainly might be at issue.
I have taken copaxone since it came out and progressed from jogging to edss 6. The heck of it was I was considered benign because I was 6years from diagnosis and still jogging. I went on cop and 11 years later here I am SPMS and a 6. I am frankly really unimpressed by the idea that copaxone will make a huge difference based on that experience, so if something else is possible to offer I'm all for it!
My MRI, BTW was inflammation and enhancement free. We're checking the spine now; I am thinking we might well find atrophy there, a hallmark of SPMS. I am not a good rev candidate, but will be keeping my ears to the ground for developments.
