Clinical trial sites in North America
Clinical trial sites: one pin for each physical site that hosts trials, placed from the address on the trial registration.

Showing the 40,000 busiest of 336,207 located sites. The map holds only the first 40,000, so narrow the filters to see the rest.
Each pin is one trial site, placed on the map from the address on the trial registration, so it shows part of where trials are run, not all of it. A site with no located address has no pin. A site with a public page on Pharma Observatory links to it; other sites show name, place and trial count only.
