NHMRC Clinical Trials Centre at the University of Sydney

The NHMRC Clinical Trials Centre at the University of Sydney is an academic research unit affiliated with both the University of Sydney and the National Health and Medical Research Council, located in Australia. It hosts the Australian New Zealand Clinical Trials Registry (ANZCTR) website, which provides a platform for registering clinical trials, updating trial details, and managing user accounts. The centre’s primary function is to maintain a transparent and accessible registry that supports researchers, sponsors, and regulators in tracking clinical study information. By offering this service, the centre contributes to the national and international clinical trials infrastructure, promoting openness and compliance with registry standards. Its affiliation with NHMRC underscores its role in supporting high-quality health research within the Australian context.

In February 2025, the ANZCTR website hosted by the centre experienced a cybersecurity breach that led to its temporary deactivation, halting trial registration, updates to trial details, and user account modifications. Affected users received an email from the University of Sydney outlining additional information and required actions, and the university apologized for the disruption. The university stated that restoration timelines would be posted on the website once they were determined. The incident disrupted the ability of researchers and sponsors to register new trials or modify existing entries. The centre’s ongoing efforts focus on restoring the website’s full functionality as communicated by the university.
