I received notificzation from Amgen in mid October/97 concerning clinical trials. Their phone number is 1-800-772-6436. When I called them in November they said that they MIGHT be into clinical trials late in the first quarter of 1998 and suggested I call them at that time. I have some literature - press releases - from Guilford that I received last year. If you would like a copy send me an e-mail with your mailing address and I will forward you copies. Eldon Green
