Is it because they've run out of money, or might it be because the drug companies do not want cures to be discovered for some diseases????? When something looks to be as promising as this intranasal GDNF, if it truly were the money... what about a foundation such as the Michael J. Fox Foundation picking up where the study left off?? I am very apprehensive... think there may just be a whole lot more to promising studies dead ends that what the general public is aware...
