Many of us forget that the normal MS patient will be on these drugs for decades, so by far one of the most important features of these products are their safety profiles.
BG-12 is dimethyl-fumarate which has been used for psoriasis in Europe since mid 1994. The side effects are well known (GI, Flushing) at its present dosage (360-480mg) and the physicians titrate the dose to ease the side effects.
Todays BG-12 trial used 240mg BID or TID, and without Biogen explaining the side effects we have to use caution going forward.
Lastly, in the end, I think they will take the safest oral and combine in with a safe injection (copaxone) and end up with wonderful, tolerable results.
