I believe that the trial with Z and dendritic cells was to have started in 2001. It was very experimental and a last ditch effort in very sick patients (as stated in one conference call a while back) and my guess was that nothing panned out so they dropped talk of it like so many other things. I can tell you that there was definately a start to it but what happened to it after that is anyone's guess. Do you remember that character that posted under the handle of "homersimpson" or someting like that? He also posted something about it. He started by saying "a little birdie told me..." That is all I have to say on the subject.
