The ability to recruit enough patients can make or break a trial – not enough participants and the trial will be dead in the water before it has even begun.

Type 1 diabetes, the disease that I mainly focus on, is relatively common in the UK – around one in 300 people in the UK alone are affected by it and face multiple daily insulin injections. So one might imagine we would have no problem recruiting patients for the trial of an exciting potential new treatment that could mean an end to those injections in the future.
As you may know already, type 1 diabetes is an autoimmune disease – the immune system mistakes cells in the pancreas as harmful and attacks them. When these cells are damaged the pancreas is unable to produce enough insulin, which plays an essential role in transferring glucose out of the bloodstream and into cells to be converted into energy. This is why patients have to regularly inject themselves with insulin to compensate.
Type 1 diabetes is a genetically complex disease – there is no single gene that causes it, but rather dozens of genes that increase the risk of developing the disease. But we do know of one particular set of genes – interleukin-2, or IL-2 – which plays a prominent role, helping regulate the immune system. We wanted to see whether IL-2 in the form of a drug called aldesleukin could halt the damage to the pancreas in people with newly diagnosed type 1 diabetes and, if so, what dose of the drug gives the best results.
The problem, of course, is that not everyone with type 1 diabetes is aware of these essential studies and the ability to recruit enough patients can make or break a trial – not enough participants and the trial will be dead in the water before it has even begun. The solution is the internet, which provides a direct communication route to individuals with type 1 diabetes allowing them to find out about studies and then immediately with ease connect to the specialist teams running these studies. To get our message out on the web we turned to our funders and the University of Cambridge.
