To apply for an ISRCTN trial ID

The CCT Editorial Team will confirm by email that we have received your application and discuss any point that requires clarification. We will assign your trial ID and add your trial to the ISRCTN register once payment has been confirmed. Please note that the number on your application is NOT your registration number (internal reference only).

  1. Log on. You will need to be logged on to the Current Controlled Trials website before you can apply for an ISRCTN. To sign up and log on, please visit my details. Signing-up for access to the CCT website is free and will enable you to register your trial for an ISRCTN and to choose to receive updates from CCT or CCT’s sister company, BioMed Central.
  2. Enable cookies. The ISRCTN online application form uses session cookies. The CCT server sends cookies to your computer during the application process. If you have set your browser not to accept cookies, you may experience problems and may be redirected to the ISRCTN Register page.
  3. Complete the whole application form. To successfully complete the application form, you will have to complete all four sections of the application in one session. You cannot save one section and return to it later. Please read the information on the ISRCTN data set, the lay summary guidance notes and the FAQ before submitting your application form. Please do not enter your trial details in capital letters as this slows the application.
  4. Arrange payment. There is a one-off charge of £210 (+VAT when applicable) for registering a trial with an ISRCTN. US$ and € prices are given on request. ISRCTNs are issued once payment has been confirmed. For more information, see our FAQs about the fee.
