UK islet autoantibody registry for early Type 1 diabetes

UK Islet Autoantibody Registry

Observational University of Oxford · NCT07125365

This UK registry collects health and antibody information from people with one or more islet autoantibodies to track who develops Type 1 diabetes and to connect them with monitoring or prevention options.

What this trial studies

This is an observational registry that enrolls people aged 6 months to 70 years living in the UK who have at least one confirmed islet autoantibody (insulin, GAD, IA-2, or ZnT8). Participants' clinical data and antibody results are recorded and followed over time to document progression between preclinical stages and clinical Type 1 diabetes. The registry links with existing cohort initiatives (such as ADDRESS-2) and includes opportunities for qualitative interviews about living with a positive antibody result. No investigational treatments are given as part of the registry, but the collected data support earlier detection of progression and help identify candidates for future prevention trials.

Who should consider this trial

Good fit: Ideal candidates are UK residents aged 6 months to 70 years with at least one laboratory-confirmed islet autoantibody and who are not currently insulin-dependent.

Not a fit: People who already require ongoing subcutaneous insulin (established clinical Type 1 diabetes), those outside the age range, or those living outside the UK are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the registry could enable earlier identification and monitoring of people at high risk of Type 1 diabetes, reduce emergency presentations like diabetic ketoacidosis, and speed recruitment into prevention studies.

How similar studies have performed: Large longitudinal cohorts have already shown that having two or more islet autoantibodies strongly predicts progression to clinical Type 1 diabetes (over 80% within 15 years), so this registry builds on established predictive findings.
