Knowing which countries to submit clinical trial results summaries to is the easy part. What becomes difficult is learning the intricacies and transparency requirements of every clinical trial registry globally, including the International Standard Registered Clinical/Social Study Number Registry (ISRCTN). Here is an overview of this registry:
Year established: 2000
Points of interest:
- The ISRCTN is a freely accessible and searchable primary clinical trial registry that accepts proposed, ongoing, or completed clinical trials
- The ISRCTN complies with international guidelines and pools its data in the International Trial Search Portal initiated by the World Health Organization, and it is recognized by the ICMJE
- Any study designed to assess the efficacy of health interventions in a human population, including both observational and interventional trials, is covered by the ISRCTN.
- The ISRCTN is controlled by its Board of Directors, who delegate day-to-day management of the registry and database to the editorial team, with additional advice from an international advisory group
- The main purpose of the ISRCTN is to register clinical trials, assign each trial with a unique identifying number, and make records publicly accessible
- The ISRCTN is the preferred partner of the United Kingdom’s Department of Health
- It is never too early or too late to register a study on ISRCTN, but it is suggested to register before patient enrollment begins
- This registry is not funded by governmental grants and those registering will incur a fee to assist in funding the ISRCTN; payment details can be found here: https://www.isrctn.com/page/faqs#payment
