I can't answer about the sites, but I do know that my research coordinator has a meeting about the upcoming trial on April 11th. We will be called in for further screening -they can only accept 10-and then start sometime in May. So, you may still have time to get in if you find a center in your area.
Keep us posted-if we both get in we can compare notes.

did you not go to a doc in Boston????Ask them
Most sites don't post on the clinical trials list. You have to call all the major medical centers near you and ask for the research coordinator for the GI department. That is how I got into prove 3.
If you live near a major city, you will probably find a center that is participating.
Good luck,
