Clinical Trials in Colorado

Every industry-sponsored study on the ClinicalTrials.gov registry that lists a US site and is open, about to open, active-but-closed, or enrolling by invitation. This deliberately excludes academic and other non-industry sponsors — the full US registry across all sponsors runs to over 22,000 recruiting studies alone.
