About this study
In plain language
This study follows people who took part in certain Immune Tolerance Network (ITN) studies for newly diagnosed type 1 diabetes. Those earlier studies used drugs that change how the immune system works. This study does not test a new treatment; it tracks how long people keep making insulin and how immune system changes relate to this.
This is a multi-center, prospective, non-interventional study that focuses on the long- term effects following participation in selected ITN new-onset Type1 Diabetes Mellitus studies with immunomodulatory agents (T1DM, T1D). This observational study will: * follow participants to determine how long they continue to produce insulin, and * will also assess how changes in the immune system over time relate to the ability to produce insulin. This information could help design better therapies for type 1 diabetes in the future.
Compensation is read from the study's own description and may be missing — always confirm with the study team.
Eligibility
