To meet WHO requirements, all trials must be updated at least once a year – even if no changes have occurred.

Important scenarios before you start

  • Annual update required (keep your ‘Up to date’ label)

To maintain the ‘Up to date’ label:

  • Go to ‘Review and submit’ page
  • Check all mandatory fields are complete, especially check Step 7: Recruitment
  • Click 'Submit' (even if no changes)

Trials registered before 25 October 2018 (not updated since)

  • Complete step 11 (data sharing plan) and step 12 (trial results)
  • No reason is required – these are new mandatory fields
  • These additions will not affect prospective/retrospective registration status

Steps to update a study

Step 1: log in and select the trial to update

  • Log in to your ANZCTR account
  • Click 'My trials' (top-right)
  • Find your trial, click 'Update trial'

Step 2: make changes

  • Tick the ‘Update’ box next to the data field(s) you need to change
  • Depending on the field, you may be asked to provide:
    • New information – this replaces the existing entry
    • Reason for the update – include when and why the change was made

Step 3: submit the changes

  • Click ‘Next step’ at the bottom of each page until you reach 'Review & submit'
  • Review your updates
  • Click 'Edit' to make changes, if needed
  • When all content is correct, click 'Submit'
  • Expect an on-screen message and email confirming receipt of your update
  • ANZCTR Staff will review your update and may contact you if there are queries
  • Once approved, your updates will appear on the public site with an 'Up to date' tag

Notes & tips

  • Fields marked * are mandatory
  • You cannot edit a trial record if it has been submitted for review to the ANZCTR
  • To delete information: tick ‘Update’, click ‘Delete’ and enter reason if asked
  • To cancel an update: click ‘Cancel’ or untick the ‘Update’ box
