Best to go to the Sanofi forum. Idk why genzyme still has it's own separate one. Then again, not like you will get real answers most of the time. I'm not with that division, but what I know is it sells itself and is a blockbuster drug. It is what is holding Sanofi together overall. I believe it still has a few more indications to release eventually. So if you have relationships, I would say it's a good spot to be for now.
