Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

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

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
Yes
What data in particular will be shared?
Seqirus supports the release of anonymized subject-level and study-level data in compliance with regulatory requirements, including Clinical Documents which are part of the CTD modules submitted to regulatory agencies for public release.

Summary results disclosure is either in document form (e.g., ICH E3 Clinical Study Report synopsis) or structured data form (such as summary results in ClinicalTrials.gov (United States) or eudract.ema.europa.eu (EU Clinical Trial Registry \[EU CTR\]).

Supporting document/s available: Study protocol, Statistical analysis plan (SAP)
When will data be available (start and end dates)?
Seqirus aims to disclose these results from clinical studies within twelve (12) months of the Study Completion unless otherwise mandated by local law or regulation.
Available to whom?
All requests will be fully vetted and data to be released approved, prior to distribution. Seqirus does not release subject-level data and study-level data if the requester's purpose is to conduct a re-analysis of the study data, as opposed to a meta-analysis.

While the URL link below does not outline the data sharing policy per se, it does present a high-level view of how the organization partners with external collaborators
