Important considerations before submitting a trial for registration with ANZCTR

Are you responsible or authorised to register a trial?

Only the trial's primary sponsor or their authorised representative should register the trial. If, for example, you are the site manager of a multi-centre trial, you should not register the trial - the trial's lead investigator, primary sponsor or overall trial coordinator should register the trial. Please contact the person responsible for the trial's overall management to check if you are authorised to register the trial before proceeding further.

Has the study already been registered on ANZCTR?

Your trial should only be registered once on the ANZCTR. Please check that the trial has not already been registered on the ANZCTR by searching the ANZCTR database before proceeding further.

Note: Preferably, a trial should be registered on only one Registry, but registering with more than one Registry is possible if required by an ethics committee or other regulatory body.

Is there a more appropriate Primary Registry in the WHO Registry Network for you to register the trial with?

Before submitting your trial for registration with ANZCTR you should consider if there is a more appropriate registry. For example, if you are a researcher based in China and your trial is going to be conducted in China, it would be more appropriate for you to register your trial on the Chinese Clinical Trial Registry (ChiCTR).

Is the trial eligible for prospective registration?

In order to obtain prospective registration, the registration process must be completed and the trial must have a trial registration number (ACTRN) issued before enrolment of the first participant.
