NCT ID NCT02734277
First seen Jun 27, 2026 · Last updated Sep 18, 2026 · Updated 3 times
Summary
This study follows people who previously took part in type 1 diabetes trials to see how long their bodies continue to produce insulin. Researchers will also look at how immune system changes relate to insulin production. The goal is to gather information that could lead to better treatments in the future. About 111 participants will be observed over time.
