The Changing Landscape of Diabetes Research in the UK
Britain has quietly become a global hub for diabetes trials, with studies running across England, Scotland, Wales and Northern Ireland. The NHS treats roughly 5.6 million people for diabetes, and that scale gives researchers something rare: access to a diverse, stable patient population with a single care record system.
The direction of travel has shifted noticeably. A decade ago, most trials focused on new drugs. Today, researchers are equally interested in technology, lifestyle programmes and care models. The NHS "soups and shakes" programme, formally known as the Type 2 Diabetes Path to Remission programme, showed what happens when diet becomes part of the research conversation. Published in The Lancet Diabetes and Endocrinology, the study found that one in three participants who completed the programme and were measured twice put their type 2 diabetes into remission, with an average weight loss of nearly 16kg among those who achieved remission.
Technology has moved just as quickly. The NHS has been rolling out hybrid closed loop systems, often called artificial pancreas technology, for people with type 1 diabetes. A pregnancy-specific version was introduced in 2025 to protect mothers and babies. These aren't theoretical gadgets; they are being tested and delivered inside the NHS itself.
For people living with type 1 diabetes, trials now ask bigger questions. The ADDRESS-2 study, running through NHS trusts, examines the characteristics of people recently diagnosed with type 1 diabetes and looks at their siblings, helping researchers understand who develops the condition and why. Meanwhile, international studies sponsored by companies like Eli Lilly are recruiting at sites across Birmingham, Blackpool, Bristol, Bromborough and Newcastle.
What Types of Trials Are Actually Recruiting
1. Remission and Lifestyle Trials
The most talked about UK research isn't a drug at all. The NHS Type 2 Diabetes Path to Remission programme uses total diet replacement products for roughly 12 weeks, followed by a structured reintroduction of food. Research showed average weight loss of over 10kg in one year for those who started early, and the programme now covers all of England.
How it works: Participants receive nutritionally complete, low-calorie soups, shakes and bars for about 12 weeks, then follow a stepped reintroduction plan supported by healthcare professionals.
Who can join: Adults with type 2 diabetes diagnosed within the last few years, referred by their GP or local diabetes team. Eligibility criteria vary by area.
2. Continuous Glucose Monitoring Trials
A 2026 ISRCTN-registered study led by Dexcom is examining whether the Dexcom ONE+ continuous glucose monitoring system, already approved and CE marked for use in the UK, improves blood sugar control when used in routine primary care. The trial is recruiting adults with type 2 diabetes who have been on the condition for at least three months, currently use insulin, and receive most of their care in general practice.
Why this matters: Most CGM research has focused on type 1 diabetes. This study asks whether the same technology helps people with type 2 diabetes who manage insulin in primary care settings, which describes a large slice of the UK population.
3. Drug Development Trials
Phase 2 and Phase 3 studies continue to run across the UK. A current example is the Eli Lilly study of an investigational agent compared with placebo in participants with type 2 diabetes already on a stable dose of semaglutide or tirzepatide, recruiting in Birmingham, Blackpool, Bristol, Bromborough and Newcastle.
In Bradford, the NIHR Bradford and West Yorkshire Commercial Research Delivery Centre launched two investigational trials in 2026 evaluating a weekly injectable treatment for adults living with obesity or overweight, with and without type 2 diabetes. Participants need to be 18 or over with at least one weight-related health condition.
4. Type 1 Diabetes Prevention and Preservation Studies
Organisations like Breakthrough T1D UK (formerly JDRF) coordinate access to trials aimed at preserving beta cell function in people recently diagnosed with type 1 diabetes. Some look for adults aged 18-44 who started insulin within the past few weeks. Others examine family members, as the ADDRESS-2 study does with siblings.
How to Find and Join a Trial Near You
Finding the right trial takes a little effort, but the UK has an unusually organised system for it.
Step 1: Check the Official Registries
The two main sources are ClinicalTrials.gov and the ISRCTN registry. Both are searchable by condition, location and phase. The ISRCTN registry is particularly strong for academic and NHS-led studies, while ClinicalTrials.gov captures many industry-sponsored trials. Neither requires a referral to browse.
Step 2: Use NHS and Charity Portals
The National Institute for Health and Care Research (NIHR) runs the "Be Part of Research" website, which lets you search current studies across the UK by postcode and condition. Diabetes UK also maintains research pages and frequently shares recruitment calls through its regional networks.
If you live in Scotland, NHS Research Scotland runs a dedicated Diabetes Register. Signing up means you can be matched with type 1 diabetes related trials and studies, mostly in your health board area, though questionnaire-based studies you can complete from home sometimes appear too. Registration is not a commitment; it simply allows researchers to contact you when an opportunity matches your profile.
Step 3: Ask Your Clinical Team
Your GP or specialist diabetes nurse is often the fastest route. NHS hospitals with research departments hold waiting lists of trials and can flag ones matching your HbA1c, treatment history and postcode. Many people discover opportunities this way without ever searching online.
Step 4: Prepare the Right Questions
Before you agree to anything, ask the research team these questions:
- What exactly will I be asked to do, and for how long?
- Will my usual diabetes care change during the study?
- What happens to my results and data?
- Are travel expenses covered for appointments?
- What happens at the end of the trial if the treatment works for me?
Weighing Participation: A Comparison of Common Trial Types
| Trial Type | Typical Focus | Time Commitment | Best For | Potential Benefits | Things to Consider |
|---|
| Lifestyle / remission | Diet replacement, weight loss | 12 months plus follow-up | Recently diagnosed type 2 diabetes | Possible remission, structured support | Requires significant commitment to meal plans |
| CGM technology | Glucose monitoring in everyday care | Several months | Type 2 diabetes on insulin | Better blood sugar insight, fewer finger pricks | Wearing a sensor, data sharing with team |
| Drug development | New medications vs placebo | 6 months to 2 years | Type 2 or type 1 diabetes, obesity | Access to newer treatments early | Chance of placebo, extra monitoring visits |
| Beta cell preservation | Protecting insulin-producing cells | 1 to 2 years | Recently diagnosed type 1 diabetes | May slow disease progression | Newly diagnosed window only, often strict criteria |
Regional Resources Worth Knowing
Research infrastructure varies by area, so it helps to know what exists where you live.
England: The NIHR network covers every region. Commercial Research Delivery Centres, like the one at Bradford Teaching Hospitals, have been expanding since 2025 to broaden access to industry trials beyond the big teaching hospitals.
Scotland: The NHS Research Scotland Diabetes Register is a standout resource. It handles the matching process for you, which suits people who prefer not to hunt for studies themselves.
Wales and Northern Ireland: Health and Care Research Wales and the HSC Research and Development Division in Northern Ireland both run searchable study finders. Local diabetes clinics in Cardiff, Swansea, Belfast and Derry regularly host national trials.
Practical Considerations Before You Sign Up
Participation is always voluntary, and you can withdraw at any time without affecting your NHS care. That is worth repeating, because some people worry that leaving a trial will complicate their treatment. It will not. Your diabetes care continues exactly as before.
Travel is the most common practical hurdle. Some trials reimburse reasonable travel expenses, but not all do, so confirm this early. Time off work is another factor; appointment frequency varies, with some studies needing monthly visits and others only a few per year.
Data and privacy deserve attention too. Research teams are required to explain how your information is stored and who can access it. The consent process exists to protect you, so use it to ask every question you have, however small it seems.
A Realistic View of What Trials Can and Cannot Offer
Trials give some people access to treatments years before they reach the market. The artificial pancreas technology now being rolled out through the NHS was itself tested in trials before becoming standard care. For others, the appeal is the structured attention: regular reviews, detailed feedback on glucose trends, and a team that takes a close interest in your numbers.
But trials are not a fast track to a cure. They carry uncertainty, extra appointments, and in drug studies, the possibility of receiving a placebo. The honest framing is that you are helping future patients as much as yourself. The data collected in Bradford, Birmingham and Bristol will shape how diabetes is managed for years.
Sarah, a 54-year-old practice nurse from Leeds with type 2 diabetes, took part in a CGM study through her local trust after her diabetes nurse mentioned it at a routine review. She told the team that wearing the sensor showed her patterns no finger-prick test ever had, and she kept using the insights long after the study ended. Stories like hers are common, but they start with one conversation.
How to Take the First Step This Week
Start small. Spend ten minutes on the NIHR Be Part of Research website entering your postcode and condition. Bookmark ClinicalTrials.gov and the ISRCTN registry. Then raise the subject at your next diabetes appointment. Ask your specialist nurse whether any local studies are recruiting and whether your profile fits.
You do not need to commit to anything today. You only need to know what exists. For the roughly 5.6 million people managing diabetes in the UK, trials represent a genuine opportunity to shape both their own care and the care of everyone who comes after them. The research system is there, the studies are recruiting, and the first step is simply asking the question.
