Re: BG-12 safety record
BIIB’s two fumaric-acid derivates—BG-12 and Fumaderm—are not identical. The difference is that Fumaderm* contains both dimethyl fumarate and monoethyl fumarate, while BG-12 contains dimethyl fumarate only. This distinction probably isn’t consequential from a safety standpoint, but I don’t think one can say for sure.
This post was prompted by an assertion on another board that BG-12 has a longstanding safety record, which is not quite correct.
