Clinical Trials in Bristol, 2026
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 — the full UK registry across all sponsors is far larger. UK studies may also be registered separately on ISRCTN.
About this register
This register is built from ClinicalTrials.gov, the trial registry run by the U.S. National Library of Medicine. It includes every industry-sponsored study on the registry that lists at least one investigative site in the UK and is recruiting, not yet recruiting, active but no longer recruiting, or enrolling by invitation: 2,883 studies in total at the last sync on 24 Oct 2026, 03:15 UTC. Academic and other non-industry sponsors are out of scope by design. The full list can be downloaded as CSV or queried as JSON through the register API.
This page shows the 10 of those studies with a site in Bristol that also match the filters currently applied.
