All trials registered and results reported

The AllTrials campaign has published a detailed plan on how all clinical trials can be registered and all results reported. This document sets out more information about achieving a situation globally where all trials are registered and results reported. It is an achievement that will involve regulators and registries, clinical trial funders, universities and institutes, professional and learned societies and medical journals, patients and researchers.

The document sets out four levels of information in clinical trial reporting: (1) knowledge that a trial has been conducted, from a clinical trials register; (2) a brief summary of the trial’s results; (3) full details about the trial’s methods and results; (4) individual patient data from the trial, and discusses the first three in detail. The AllTrials campaign is not calling for individual patient data to be made publicly available

This document is part of a continuing discussion which many different organisations are working on elaborating further over coming weeks and months. Please email views and contributions to: alltrials@senseaboutscience.org

Study and protocol registration

Planned clinical trials should be registered, with a summary of the trial protocol, before the first participant is recruited. Past trials that were not registered should now be registered retrospectively. This is essential if the trial was on medicines or interventions that we currently use (this includes some trials conducted before registries were established).

Summary results reporting

A summary of results should be publicly available where the trial was registered, within one year of completion of the trial. Summary results from all past trials of medicines currently in use should be made publicly available on a register now. Summary results include information on the primary and any secondary outcomes measured and statistical analysis. This is part of the structured information that global registries should support. 

A full report

Trial sponsors or others who produce a full report for marketing authorisation or any other purpose should make this publicly available. The narrative reports of adverse events and individual patient data in a full report can be redacted and available on request to researchers, in the same way that reports of adverse incidents currently are, with a commitment that no reasonable request will be refused.
