Plain English summary of protocol
Background and study aims
Diabetes is a life-long condition that causes a person’s blood sugar to become uncontrolled and too high. This condition usually forms while someone is young. There are similarities in the presentation of type 1 diabetes, for example, similarities in some symptoms, but there are also many differences. An up-to-date picture of type 1 diabetes at onset in children and adults in modern and diverse Britain is needed to improve understanding of these similarities and differences. There are other studies that are investigating ways of preserving beta cell function soon after diagnosis, but finding people to take part in these studies can be challenging. The aim of this study is to help to put people interested in taking part in research in touch with researchers running studies. It also supports other research by making the anonymous information blood and DNA samples collected in the study, available to other researchers.
Who can participate?
Children aged from 5 years and adults of any age who have had type 1 diabetes for less than 6 months. Siblings without diabetes can also participate.
What does the study involve?
Participants have an interview with a researcher to collect information about medication, medical history and family history and onset of diabetes (not siblings). An optional blood sample for testing and storage of blood and DNA is taken from participants. Participants allow the study team to collect health information from medical records and from central NHS systems. Participants are asked to consent to being contacted about other diabetes research, but are under no obligation to take part in other research. They are also asked to consent to the sharing of their anonymous information and biological samples for other research relevant to diabetes.
What are the possible benefits and risks of participating?
There is no direct benefit to participants. An improved understanding of type 1 diabetes at onset may lead to benefits for people with type 1 diabetes in the future. Giving a blood sample has a risk of bruising and discomfort.
Where is the study run from?
This study is being run by Imperial College London (UK) and takes place in hospitals across the UK.
When is the study starting and how long is it expected to run for?
July 2010 to April 2025
Who is funding the study?
Diabetes UK (UK)
(Note: Juvenile Diabetes Research Foundation Limited (JDRF) (UK) funded between July 2010 to December 2018)

| Scientific title | An incident and high risk type 1 diabetes research cohort - After Diagnosis Diabetes REsearch Support System-2 (ADDRESS-2) |
| Study acronym | ADDRESS-2 |
| Study objectives | The aim of this study is to characterise new-onset type 1 diabetes in the modern and diverse UK population. To link people wanting to participate in type 1 diabetes research with researchers and studies. To support other type 1 diabetes research via an open access repository of data and biological samples. |
| Ethics approval(s) | Approved 03/10/2010, South Central – Berkshire NHS Research Ethics Committee (Bristol HRA Centre, Bristol, BS1 2NT, United Kingdom; +44 (0)207 104 8178; berkshire.rec@hra.nhs.uk), ref: 10/H0505/85 |
| Health condition(s) or problem(s) studied | Type 1 diabetes mellitus |
| Intervention | Demographic, clinical and routine laboratory data are collected via interview with participants and from their medical records at a single study visit. An optional blood sample is collected for the measurement of islet autoantibodies (markers of autoimmune activity in type 1 diabetes), extraction and storage of DNA and storage of blood. Within the first year of diagnosis, follow-up data are collected from medical records to confirm or record a change in diabetes sub-type. |
| Intervention type | Other |
| Primary outcome measure(s) |
Autoantibody status is measured in a single laboratory using established radiobinding assays at baseline and characteristics at presentation are measured using patient interviews, medical records and pathology systems at baseline. |
| Key secondary outcome measure(s) |
There are no secondary outcome measures. |
