Type 1 Diabetes Extension Study

National Institute of Allergy and Infectious Diseases (NIAID) · NCT02734277

What this trial studies

This observational study follows participants who previously took part in selected Type 1 Diabetes Mellitus studies involving immunomodulatory agents. It aims to assess how long these individuals continue to produce insulin and how changes in their immune system over time relate to insulin production. Participants may have follow-up visits ranging from one to five years, which will include health assessments, blood and urine collections, and mixed meal tolerance tests for certain individuals. The findings could inform the development of improved therapies for Type 1 Diabetes in the future.

Who should consider this trial

Good fit: Ideal candidates are individuals who have previously participated in an Immune Tolerance Network approved Type 1 Diabetes study.

Not a fit: Patients with medical conditions that could interfere with the trial or those unable to comply with the study schedule may not benefit.

Why it matters

Potential benefit: If successful, this study could lead to better understanding and therapies for managing Type 1 Diabetes.

How similar studies have performed: Other studies involving immunomodulatory treatments in Type 1 Diabetes have shown promise, suggesting potential for success in this approach.
