AgeX Trial Data Privacy Notice

Version 2.0 May 2023

1. What is the purpose of this Notice?

The University of Oxford is committed to protecting the privacy and security of your personal information (‘personal data’). 

This privacy policy describes how we collect and use your personal data during your participation in the AgeX trial) in accordance with the UK General Data Protection Regulation (GDPR). 

It is important that you read this policy, together with any other privacy policy we may provide on specific occasions when we are collecting or processing information about you, so that you are aware of how and why we are using your information. We may update this policy at any time.

2. Glossary

Where we refer in this policy to your ‘personal data’, we mean any recorded information that is about you and from which you can be identified. It does not include data where your identity has been removed (anonymous data).

Where we refer to the ‘processing’ of your personal data, we mean anything that we do with that information, including collection, use, storage, disclosure or retention. 

3. Who is using your personal data?

The University of Oxford (the University’s legal title is the Chancellor, Masters and Scholars of the University of Oxford) is the “data controller” for the information that we obtain from you or others as part of the Age Extension (AgeX) Trial. This means that we decide how to use it and are responsible for looking after it in accordance with the UK GDPR. 

Access to your data will be provided to designated members of our staff who need to view it as part of their work in carrying out the purposes set out in section 5. We also share it with the third parties described in section 6. 

4. The types of data we hold about you and how we obtained it

The information we collect when you are randomised into the trial includes personal details about you including your name, NHS number and date of birth provided via the NHS Breast Screening Programme and NHS England. 

We also collect additional information from third parties including from NHS England. This information includes special category (sensitive) data concerning your health, such as information on cancer registrations, cancer screening and hospital admissions. NHS England also provides us with information about people who have passed away, which includes date of death and cause of death. 

5. How the University uses your data

The NHS routinely offers breast screening every three years to all UK women aged 50-70. We combine all the information described in section 4 to study the effects of offering an additional screen to women aged 47-49 and, separately, of offering an additional screen to women after aged 71-73. For example, we use linked cancer registration data to compare the number of women who develop breast cancer according to whether or not they were offered an additional screen. 

The legal basis for the processing of your personal data for the AgeX trial is that it is ‘a task in the public interest’ (Article 6(1)(e) UK GDPR). In addition, a required condition under the UK GDPR to process your special category (sensitive) personal data is met as it is necessary for archiving purposes in the public interest, scientific or historical research purposes or statistical purposes (Article 9(2)(j) UK GDPR). 

We will only process your personal data for the purposes for which we collected it. This also includes using personal details such as name, NHS number and date of birth to link with the data providers described in section 4. We do not use your personal data for any form automated decision making or public profiling. 

Please note that we may process your data without your knowledge or consent, in compliance with the above rules. The law that permits us to perform this is Section 251 of the NHS Act. 

6. Who has access to your data?

Access to your data within the University will be provided to those who need to view it as part of their work in carrying out the purposes described above. The people who analyse the information will not be able to identify you and will not be able to find out your name, NHS number or your contact details. 

In order to perform our research and other legal responsibilities or purposes, we will, from time to time, need to share your information with the following: 

  • collaborating research organisations working with us
  • external organisations providing services to us, including those who provide us with data; and
  • external regulatory bodies. 

Where information is shared with third parties, we will seek to share the minimum amount necessary, including pseudonymising your data where possible. This means we remove your identity and replace it with a code before sharing the information. Only we have access to the ‘key’ linking the code to your identity. 

All our third-party service providers that process data on our behalf are required to take appropriate security measures to protect your data in line with our policies. We do not allow them to use your data for their own purposes. We permit them to process your data only for specified purposes and in accordance with our instructions. 

7. Transfer of your data outside of the European Economic Area (EEA)

Your data is stored on our secure servers and/or in our premises within the UK. It will not be transferred to anyone outside the UK. 

8. Retention Period

The AgeX Trial is a long term trial, still under active follow-up. We hope to continue follow-up until the early 2030s and we will retain your data for as long as we need it to meet our purposes, including our medical research and any relating to legal, accounting, or reporting requirements. 

9. Security

Your data will be held securely in accordance with the University’s policies and procedures. Further information is available on the University’s Information Security webpages

10. Your rights

Data protection regulation provides you with control over your personal data and how it is used. When your information is being used in research, however, some of those rights may be limited in order for the research to be reliable and accurate. Further information about your rights with respect to your personal data is available on the Oxford University Compliance webpages

If you want to exercise any of the rights described above or are dissatisfied with the way we have used your information, please contact the University’s Information Compliance Team. The same address can be used to contact the University’s Data Protection Officer. If you remain dissatisfied, you have the right to lodge a complaint with a supervisory authority. In the UK, this is the Information Commissioner’s Office (ICO). A complaint to the ICO can be made by visiting their website or by calling their helpline on 0303 123 1113. 


We reserve the right to update this privacy notice at any time, and will seek to inform you of substantial updates. We may also notify you in other ways from time to time about the processing of your personal data.
