Clinical Trials in London, 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: 2,878 studies in total at the last sync on 07 Nov 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 2,026 of those studies with a site in London.

How many clinical trials are recruiting in London?

983 of the 2,026 studies on this page are recruiting new participants as of the 07 Nov 2026, 03:15 UTC sync. A further 26 have not yet opened recruitment, 956 are active but closed to new participants, and 61 are enrolling by invitation only. Eligibility for any study is decided by its study team.

Listing here is informational and not medical advice; eligibility is determined by each study team. Compare pay for the teams running these studies in the UK Pharma Salary Guide, or see the Ireland, EU and USA registers.
