Thanks to readers’ comments, I learned about a few more super helpful resources for tracking down clinical trials…
This one is on the Livestrong site – very easy to use. I found five matches: http://www.livestrong.org/site/c.khLXK1PxHmF/b.4169727/k.9BEA/Clinical_Trials/apps/s/link.asp
This one is extremely comprehensive: http://clinicaltrials.gov/ct2/search
And this site lists clinicaltrials.gov and many others: http://www.centerwatch.com/clinical-trials/listings/
Many thanks to Jodi & Duckie for the links!
