Still one of the most promising treatments in development, inspite of all the barriers placed in its way. Truths about the amgen trial now are finally being discussed and reported -- GDNF didn’t fail, but the trial design did. Dr. Clive Svendsen, a highly repected neuroscientist is quoted saying about the Amgen phase II trial "That trial was basically designed to fail," says Clive Svendsen, a neuroscientist who was a consultant to Amgen on the study. Amgen chose a catheter that was thicker than Gill's (used in the phase I trials), dripping GDNF into the brain rather than delivering it under pressure. Consequently, the GDNF solution simply refluxed up the outside of the catheter, says Svendsen, now director of the Regenerative Medicine Institute at Cedars-Sinai Medical Center in Los Angeles. Amgen declined to comment about the trial for this story. In 2004, amid a huge spate of negative publicity, it mothballed its GDNF project." It was a “business decision” so much time has been wasted! The article also discusses ArmaGen's (a small biotech) research on a non-surgical treatment that passes thru the BBB to deliver GDNF. They had . promising pre-clinical results but they might run out of ,money before it gets thru the cliunical trial process and they haven’t found more funding. Will we loose out again due to “business decisions? Also discuses Ceregene's research with neurturin and other upcoming trials for gene therapy and stem cell delivery method. There are of course disagreements about which delivery method will work best.
