Rexin G was posted 08/21/2006 11:25 pm by Mook Message Text: The Mayo Clinic in Minnesota currently is doing a clinical trial on Rexin-G. It's still open and they are recruiting. So far they've only enrolled 4 people, with mixed results. They've seen density changes in the tumor - it appears to become more cystic. But, as the primary researcher told me, it's not a ''slam dunk.'' It is a Phase I/II clinical, and I believe they are in discussions with the FDA to change the dosing schedule to see if they can get a better response.
