Tom,

NCI has a very nice discussion of the different kinds of trials on its
gopher.

CLINICAL TRIALS FOR PHYSICIANS
CLINICAL TRIALS FOR PATIENTS

Get to the NCI gopher, then PDQ INFOMATION/OTHER PDQ INFORMATION.

I use these in my classes on research methods for fellows.

These publications are  also available by e-mail and ftp.

Let me know if you have trouble getting them.
