This is a website associated with a very nice book on the pragmatic aspects of running a clinical trial. I came across this site because I was looking for a simple example of a letter to doctors asking them to help recruit patients for a clinical trial. This was in an appendix along with other nice examples of things like case report forms, serious adverse event forms, HIPAA consent template, etc. You can download a free PDF version of this book or you can buy a paper copy.
