ISRCTN registry
We’ve updated our website!
We’re excited to announce that the ISRCTN website has been refreshed to improve your experience. As part of this update, we’ve made several enhancements to both the application form and the update your record form.
These changes are designed to make the registration process quicker and easier, helping you submit and manage your study information more efficiently.
If you’ve already started an application using the previous version of the form, don’t worry — your saved progress is still available and can be completed as usual.
We hope you find the new features helpful and welcome any feedback you may have at info@isrctn.com

The ISRCTN registry is a primary clinical study registry recognised by the World Health Organisation (WHO) and the International Committee of Medical Journal Editors (ICMJE) that accepts all clinical research studies (whether proposed, ongoing or completed), providing content validation and curation and the unique identification number necessary for publication. All study records in the database are freely accessible and searchable.
ISRCTN supports transparency in clinical research, helps reduce selective reporting of results and ensures an unbiased and complete evidence base.
The registry aims to include all interventional and non-interventional clinical studies that prospectively involve UK participants and evaluate biomedical or health-related outcomes.
Studies conducted outside the UK or considered to be non-clinical studies (e.g. public health studies) can be registered on ISRCTN.
Studies should ideally be registered prospectively (before recruitment starts). ISRCTN also accepts studies registered retrospectively once they are underway or after completion.
