Australian New Zealand Clinical Trials Registry

The Australian New Zealand Clinical Trials Registry (ANZCTR) operates as a free, online register that accepts, maintains and displays information about clinical trials conducted in Australia, New Zealand and other countries. Researchers, trial sponsors, ethics committees and members of the public can use the service to register new trials, update existing trial details and search for trial data that is made publicly available. The registry supports the submission of structured data fields that cover trial identification, design, interventions, outcomes and contact information, thereby facilitating transparency and accessibility of clinical research. By providing a searchable database, ANZCTR enables stakeholders to identify ongoing studies, avoid unnecessary duplication and inform evidence‑based decision making in healthcare. The service is offered without charge to users, reflecting its commitment to open science and the dissemination of trial information.

ANZCTR holds the status of a primary register within the World Health Organization’s International Clinical Trials Registry Platform, which underscores its role in global trial registration standards. The registry contains thousands of trial records that are accessed by users worldwide, indicating a broad international reach despite its regional focus. Its distinguishing attributes include a specialised focus on clinical trial transparency, a regulatory alignment with national health department initiatives aimed at improving research governance, and a sector positioning as a not‑for‑profit partnership between academic and government entities. Notable competencies of the organisation encompass rigorous data validation processes, multilingual support for users and seamless integration with other clinical trial registries to enhance data interoperability. Structurally, ANZCTR is hosted by the University of Sydney and receives funding from the Australian Government Department of Health, operating as an independent, not‑for‑profit service without a defined parent or subsidiary relationship.
