The Australian Teletrial Program (2022) provides the following definition:
A teletrial is a group of clinical trial sites that work together to conduct a clinical trial under the supervision of a Primary Site.
A teletrial uses telehealth technology to communicate between the Primary Site and Satellite Site/s and enables delivery of aspects of a clinical trial closer to home for patients, particularly in regional, rural and remote locations. A Principal Investigator supervises Associate Investigator/s to conduct a clinical trial at a Satellite Site which is geographically remote from the Principal Investigator’s Primary Site.
The Principal Investigator remains responsible for the trial. A detailed Supervision Plan is required, in addition to a Delegation Log required by ICH GCP for all Satellite Sites regardless of experience. Trial participants may have trial visits at both the Primary and Satellite Sites, as determined by the Protocol and Supervision Plan.
Teletrials are considered a 'sub-branch' or type of Decentralized Clinical Trial (DCT). The term DCT is commonly used by sponsors.
The DCT model does not typically specify the difference between a Primary and Satellite Site but conceives of a spectrum of activities that may be interpreted according to sponsors' and clinicians' needs. Essentially very similar to Teletrials but there are not enough published examples yet to determine fixed models.

A fully virtual clinical trial is one that is completely technology-based and can include those run by registry searches and data mining. That means there are no traditional sites, no physical locations used, and no face-to-face interactions. Actual participants may be involved but their interaction is all via web sites, phones, apps, watches, and e-diaries.

The Australasian Teletrial Model released in September 2016 was developed by the Clinical Oncology Society of Australia (COSA) Regional and Rural Group in consultation with clinical trial sponsors, clinicians, health administrators and regulatory bodies.

The term teletrial was codified in the National Principles for Teletrials in Australia in 2021.
