Diabetes Remission Clinical Trial

DiRECT 2023 Update

The main task for 2023 has been to complete analyses on the DiRECT Extension Study, after all data collection finished in 2022.

For the DiRECT Extension study low-intensity support was provided to try to help maintain weight loss and remission for all the remaining DiRECT Intervention group participants, for 3 more years after the 2-year randomised trial ended. The preliminary 5-year results were presented at the annual UK Association of Physicians meeting, and also at the Diabetes UK Professional Meeting, both in Liverpool. A full paper has been written and submitted for publication.

Several secondary analyses from the original 2-year DiRECT trial have also been completed, and the DiRECT data have been shared with other research groups in collaborations to examine how genetic markers of coronary heart disease risk predict clinical events, and how metabolomic markers (small peptides, and parts of proteins which are associated with diabetes and cardiovascular disease) in the bloodstream improve with the DiRECT intervention. Links to the publications are in the Publications section of this website.

The impacts of the DiRECT trial continues to grow, both within Britain and internationally. New clinical guidelines in several countries, and from the European Association for the Study of Diabetes, now recommend weight loss and remission as a primary management target for people with type 2 diabetes. In both Scotland and England, the National Health Services have established strategies to divert resources and provide effective weight management in national-level Diabetes Remission programmes. People living with type 2 diabetes across the world are asking for treatment and support to achieve remission, and large numbers have been successful. Importantly, the STANDby trial, using the same Counterweight intervention as DiRECT, showed that people of South Asian ancestry, who have very high rates of type 2 diabetes at lower BMI and younger ages, can achieve remission, with loss of ectopic liver fat, just like people of European heritage.

Further afield, Type 2 Diabetes Remission projects based on DiRECT have been conducted in many other countries, notably including Australia and New Zealand. Pilot food-based intervention projects based on DiRECT are also running in Lower and Middle Income Countries such as Nepal, where the personal risks and community burdens from Type 2 Diabetes are much greater, but modern drug treatments are unavailable or unaffordable.

DiRECT 2021 Update

In 2020 and 2021, we are continuing to collect data from participants in DiRECT, into their 4th and 5th years of support and follow-up. Covid 19 has made both weight-loss maintenance and data collection difficult, but the Glasgow and Newcastle University research teams have continued to analyse the 2-year results. Important new papers from DiRECT have been published, on the predictors of success for weight loss and remission, the cost-effectiveness of the treatment (it saves healthcare money!) and on the detailed mechanisms behind repairing the pancreas and restoring insulin production.

Now that providing the DiRECT intervention has been shown to save NHS costs, it is now becoming widely available in UK. All Scottish Health Boards received the training to provide the DiRECT/Counterweight-Plus intervention for remission of type 2 diabetes in NHS Scotland by December 2019. In September 2020, a programme was launched to introduce the intervention for 5000 people with type 2 diabetes in selected areas of England.

Diabetes UK 2019 Panel

On the 5th December 2017 the 12 month primary outcome results of the Diabetes Remission Clinical Trial (DiRECT) were presented at the International Diabetes Federation Congress hosted in Abu Dhabi. Talks were delivered by both Professor Roy Taylor and Professor Mike Lean, with both pictured here with Professor Naveed Sattar enjoying some refreshments following the event.

Trial description

DiRECT is a research study investigating whether offering an intensive programme for weight loss and weight loss maintenance would be advantageous for people with Type 2 diabetes. Specifically, this programme aims to increase the number of people who can become non-diabetic. Participants are recruited only via NHS General Practices which are taking part in the study, and individuals cannot be accepted in DiRECT. General Practices are randomly allocated to offer their patients one of two treatments. Each treatment has already been shown to be effective, and the question of DiRECT is whether one is better than the other. All participants will be followed for at least 2 years, to see how many remain diabetic under each treatment, and how that relates to their weight. Some participants will also undergo detailed tests concerning the amount of fat in their liver and pancreas.

DiRECT is the largest research study, to date, ever supported by the charity Diabetes UK. Additional support is provided by Cambridge Weight Plan pro bono but with no input into study design, execution or analysis. It is being conducted in NHS primary care practices in Scotland and in Tyneside, the intervention being delivered by NHS staff in routine practice. Defined training for these staff is being provided using the Counterweight Plus approach. The NHS “sponsor” is NHS Greater Glasgow and Clyde

Study Protocol DiRECT Protocol

What is diabetes?

There are several types of diabetes. All are metabolic disorders which can result in progressive damage to the main organs in the body. Diabetes especially damages the heart, brain, feet and legs, eyes, kidneys and nerves. There are two main types of diabetes: Type 1 (caused by an immune attack destroying the pancreas cells which make insulin), and Type 2 (caused by being overweight and resistant to the effect of insulin, with gradual loss of ability to make enough insulin). DiRECT is researching the treatment of Type 2 diabetes, which is the most common type, and the most expensive for health services.

Why is DiRECT important?

Some people with Type 2 diabetes can become non-diabetic again, at least for a period. That is called a remission of diabetes. A remission of diabetes will allow the patient to stop taking anti-diabetic drugs. This is important as the drugs are inconvenient and can cause side-effects. Also these drugs cost the NHS around £800million per year. If diabetes remission is long term this would prevent or delay the long-term damage which diabetes causes in different body-organs. The mechanisms underlying the return of normal glucose control will also be examined in the Tyneside cohort. Detailed tests using magnetic resonance scans and insulin secretion tests will be carried out.
A new treatment programme which helps to produce remissions in type 2 diabetes could therefore be advantageous for people with diabetes, and also save treatment costs. For people who achieve a long term remission, the effect upon their future health and well being could be very great indeed.
