ISRCTN registry

20th Anniversary

ISRCTN is a clinical trial registry recognized by the WHO and ICMJE that accepts planned, ongoing or completed studies of any design. ISRCTN is committed to supporting research transparency. The first ISRCTN numbers were issued in 2000, so we are celebrating 20 years of ISRCTN in 2020.

New dashboard view

As part of our ongoing development of the ISRCTN website, we are looking at introducing a dashboard-style view of the registry database, which can be used to see an overview of the activity and transparency status of studies. You can filter the results to see studies that are relevant to you (e.g. sponsored or funded by a particular institution). To see the prototype dashboard and to give us your valuable feedback, please click here. There is a link to provide your feedback on the dashboard, alternatively you can access the feedback form here.
