Pointed out before the 2-73 stands as both a threat and an opportunity to Biogen's future business.
As appreciative as Anavex was when Biogen showed an interest almost a year ago I doubt they signed away the farm on the first date.
There could be a few interested party’s watching from the sidelines contemplating the future with and without Anavex as part of their pipeline. No one willing to stick their neck out until further developments spell out a clearer picture.
The negatives of going forward without Anavex may outweigh the normal reservations in an environment without everything laid out.
We have the skeptics here to keep us distracted but could have many more science fans in the wings, waiting and watching.
