Clinical Trials in London

Every industry-sponsored study on the ClinicalTrials.gov registry that lists a UK site and is open, about to open, active-but-closed, or enrolling by invitation. This deliberately excludes academic and other non-industry sponsors โ€” the full UK registry across all sponsors is far larger. UK studies may also be registered separately on ISRCTN.
