Scientists launch study to decode why diabetes affects people differently
NCT ID NCT07670871
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
The EXPAND study is a research project that will enroll 440 adults with and without pancreatic conditions to understand why type 2 diabetes varies so much from person to person. Researchers will collect data on metabolism, genetics, and pancreas health to identify distinct diabetes subtypes. This is an observational study, meaning no new treatments are being tested, but the findings could pave the way for more personalized diabetes care in the future.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could lead to better ways to classify and treat different types of diabetes based on individual biology.
- What could go wrong
- This is an observational study, not a treatment trial, so it won't directly benefit participants. Results may take years to influence clinical practice.

Who is studied
Participants will be recruited from patients receiving care at Fondazione Policlinico Universitario A. Gemelli IRCCS (Rome, Italy). The study population includes adults with and without pancreatic disease, including individuals undergoing pancreatic resection, patients with chronic or previous pancreatitis, subjects at increased risk of type 2 diabetes mellitus, and individuals with newly diagnosed type 2 diabetes mellitus.
