Type 1 Diabetes Clinical Trials in the UK: A Complete Guide for 2026
Everything you need to know about type 1 diabetes in the UK, including immunotherapy to preserve beta cells, artificial pancreas systems, stem cell therapies, and islet cell transplantation. This guide covers what is being tested, who can participate, and how to find trials near you.
Why Type 1 Diabetes Clinical Trials Matter
Clinical trials are essential for developing new treatments for type 1 diabetes. They test whether new drugs, devices, or approaches are safe and effective before they become widely available. In the UK, the NHS actively participates in trials across hundreds of hospitals and research centres, making it one of the best places in the world to access cutting-edge treatments.
For type 1 diabetes patients, trials can offer access to treatments that are not yet available on the NHS, close monitoring by specialist teams, and the opportunity to contribute to medical knowledge that helps future patients.
Current Treatment Landscape
Standard treatment for type 1 diabetes follows established pathways based on disease stage and individual patient factors. For newly diagnosed, the standard approach is immunotherapy, anti-cd3 (teplizumab), anti-thymocyte globulin, low-dose anti-il-2. For established — insulin therapy, the standard approach is multiple daily injections, insulin pump, hybrid closed-loop systems. For complications, the standard approach is ace inhibitors, sglt2 inhibitors, screening and specialist referral. For advanced — islet/cell therapy, the standard approach is islet cell transplant, stem cell-derived beta cells, encapsulation therapies.
What Types of Trials Are Available?
Immunotherapy
Trials testing drugs like teplizumab and anti-thymocyte globulin to slow or stop the immune attack on insulin-producing beta cells, particularly in newly diagnosed patients.
Artificial Pancreas
Closed-loop insulin delivery systems (hybrid and fully automated) that use continuous glucose monitors and algorithm-driven pumps to manage blood sugar without manual input.
Stem Cell Therapy
Vertex VX-880 and similar stem cell-derived islet cell therapies aim to restore natural insulin production. Early trial results have been groundbreaking.
Islet Transplantation
Donor islet cells are transplanted into the liver to restore insulin production. Available on the NHS for severe hypoglycaemia unawareness.
Who Can Join a Type 1 Diabetes Trial?
Eligibility criteria vary between trials, but common factors include:
- A confirmed diagnosis of type 1 diabetes
- Being at a specific disease stage or treatment line
- Age requirements (most adult trials accept 18+)
- No conflicting medical conditions or medications
- Willingness to attend regular hospital visits

Frequently Asked Questions
Can I join a type 1 diabetes trial if I was diagnosed years ago?
Yes. While some trials target newly diagnosed patients (within 3 months), many focus on established type 1 diabetes — testing new insulin delivery technology, complications treatments, and cell therapies for people at any disease duration.
What is the artificial pancreas (closed-loop system)?
A closed-loop system combines a continuous glucose monitor with an insulin pump, controlled by an algorithm that automatically adjusts insulin delivery. Several UK trials are testing next-generation fully automated systems.
Are stem cell cures for type 1 diabetes available in trials?
Yes. Vertex VX-880 (stem cell-derived islet cells) has shown remarkable early results in US trials, and UK sites are expected to participate in later-phase studies. Several other stem cell approaches are also in clinical testing.
Do type 1 diabetes trials pay participants?
Most therapeutic trials do not pay participants, but cover trial-related costs and travel. Healthy volunteer Phase 1 trials (often for new insulins or devices) may offer payment. Check each trial listing for details.
