Multi-center could be Japan, Germany, and Australia, all with protocols approved by the U.S. and funded primarily by their individual governments.
That is correct except for the latter part...obtaining funding from the individual governments would be extraordinarily unusual and exceedingly unlikely.
IMO, AVXL doesn't have enough evidence to get any other entity interested in funding or partnering with them. They will be funding the P2/3 through sale of stock...which will be greeted here with joyful cries of "isn't it great they don't have to share any profits"...but its not a good thing.
