We are experiencing 4 week turn-around time in review of submissions and resubmissions. We recommend commencing this process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission. We currently do not have the capacity to expedite reviews.

Note also there are delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers
