Type 1 Diabetes Extension Study

Summary

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.

Detailed Description

Depending upon a participant's level of insulin production, participation may be as short as one return visit or a maximum of five years. Evaluation visits will include: * Overall health assessments * Blood and urine collections * Mixed meal tolerance test (MMTTs) for certain participants, per protocol.
