Please be advised that due to the high volume of submissions, the ANZCTR is currently experiencing delays in processing submissions from those outside of Australia and New Zealand. As the ANZCTR is funded by Australia and New Zealand, we must prioritise submissions from these countries first, therefore international submissions should allow additional time for registration or updates to registration records. Apologies for any inconvenience caused.

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
