Here are a few resources which I’m sure some of you already know about:

@todrobbins really useful. Would you have any further info on each of these. E.g. description, size, openness.

Also see clinicaltrials.gov (fact sheet: http://www.nlm.nih.gov/pubs/factsheets/clintrial.html) – they have a pretty good API.

There is also recent(ish) legislation to require studies to publish not only enrollment status but also results – see FDAAA 801 and the Final Rule - ClinicalTrials.gov
