The University of Oxford (UoO) and GRAIL Bio UK Ltd are joint controllers. The processors are GRAIL Limited Liability Company (GRAIL LLC), Amazon Web Services (AWS) UK and AWS, Inc (USA). This audit focussed on GRAIL LLC and AWS USA.

The UoO and GRAIL LLC have access to pseudonymised record-level data linked against a cohort of individually consented patients recruited to SYMPLIFY, a study designed to assess GRAIL’s Galleri multi-cancer early detection (MCED) test in individuals referred with signs and symptoms of cancer. GRAIL LLC receive pseudonymised record-level NHS England data from the UoO. AWS USA supply IT infrastructure for GRAIL LLC and are therefore listed as data processors. AWS USA supply support to the system, but do not access data.

Enrolled participants consent to the transfer of their pseudonymised health data to GRAIL LLC in the US, for purposes permitted by the study participant consent form. There are 6,240 consenting SYMPLIFY participants.

As the audit was conducted remotely, the Audit Team was unable to review or assess the physical environment.

The findings are based on evidence and information provided during the interviews or supplied after.

The interviews during the audit were conducted through video conferencing. This is an exception report based on the criteria expressed in the Data Sharing Audit Guide version 4.
