ISRCTN is the UK's only WHO-recognised primary clinical study registry, accepting registration of interventional and non-interventional studies at any stage (proposed, ongoing, or completed). All records are freely searchable and openly accessible, supporting UK transparency requirements effective April 2026 that mandate prospective registration and results publication within 12 months.
