did 60 minutes or one of the other news related programs cover the GDNF controversy awhile ago? seems to me, the news program showed footage of the vice president of Amgen at an Amgen conference stating that the delivery system for GDNF was too expensive and that there were not enough surgery suites manned by neurosurgeons to perform all the catheter implants required if the drug was marketed and used as in the trials. that another delivery system had to be developed, thus the drug was going to be pulled out of the trials. or am i making all this up???madelyn
