The NHS in England and Wales has begun offering teplizumab, the first treatment shown to delay the onset of type 1 diabetes.
Teplizumab is an immunotherapy given before symptoms appear. By easing the immune system’s attack on the insulin-producing cells in the pancreas, it can give people around three extra years before they develop symptoms and need to begin lifelong insulin. It can be given from the age of eight, as a daily infusion over 14 consecutive days.
The National Institute for Health and Care Excellence (NICE), which recommended the drug, estimates around 1,100 children and adults could be eligible in the first year. Because it must be given before symptoms develop, patients first need a blood test showing the immune system has started to attack the pancreas. Routine screening is not yet available on the NHS, so most people currently learn they are at risk through other tests or family history.
Earlier research that helped make the drug possible was funded by the charity Breakthrough T1D, with several further immunotherapies now in development. In Scotland, the Scottish Medicines Consortium expects to issue its advice in early 2027.
Treatments like teplizumab only reach patients because people take part in research. If you, or someone in your family, would like to get involved in type 1 diabetes research in the UK, you can register your interest with us.
