Thank you to all Site teams, Participants and Everyone Involved for a Successful 2025

Trial Update

The full amendment pack for Substantial Amendment 05 is now available. Please access the password protected area of this website. The Substantial Amendment 05 Document Pack file is located under the Essential Documents page.

The team have also put together a short slide set outlining the changes which should help to reduce workload at sites. This is titled Substantial Amendment 05 Training and is accessible via the same section of the Essential Documents page.

Please note we have allowed additional time (2nd February 2026) for sites to implement the changes but sites can come on board to Protocol 8 as soon as local and CTU approvals have been received.

The trial source data worksheets and database will also be updated and released in January 2026.

Thank you for all your hard working.
