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 study on the registry that lists at least one investigative site in Norway and is recruiting, not yet recruiting, active but no longer recruiting, or enrolling by invitation: 1,262 studies in total at the last sync on 14 Nov 2026, 03:18 UTC. The full list can be downloaded as CSV or queried as JSON through the register API.

This page shows the 730 of those studies with a site in Oslo.

How many clinical trials are recruiting in Oslo?

393 of the 730 studies on this page are recruiting new participants as of the 14 Nov 2026, 03:18 UTC sync. A further 33 have not yet opened recruitment, 273 are active but closed to new participants, and 31 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. See also the Ireland, UK, EU, USA and China registers.
