The ANZCTR is an online registry of clinical trials being
undertaken in Australia, New Zealand and elsewhere.

*Note that due to a higher than usual number of registration and update submissions, there may be delays in processing.*
Thank you for your patience and apologies for any inconvenience.

Searching for a trial?


The search function allows you to conduct either a basic search or an advanced search of clinical trials available on the ANZCTR database. Once you find a relevant trial, you will be able to contact the person listed as the 'public contact' on the trial record for more information.

Want to register a trial?


In order to fulfil the prospective registration requirement, i.e. obtain registration number (ACTRN) prior to enrolment of the first participant, we recommend that Australian and New Zealand registrants commence the registration process at least three weeks prior to the anticipated recruitment start date. All other registrants should allow substantially longer.
