TrialNet Pathway to Prevention of T1D
Recruiting
Rationale: The accrual of data from the laboratory and from epidemiologic and prevention trials has improved the understanding of the etiology and pathogenesis of type 1 diabetes mellitus (T1DM). Genetic and immunologic factors play a key role in the development of T1DM, and characterization of the early metabolic abnormalities in T1DM is steadily increasing. However, information regarding the natural history of T1DM remains incomplete. The TrialNet Natural History Study of the Development of T... Read More

Acetazolamide in Persons With Type 1 Diabetes - Crossover Trial
Recruiting
The goal of this study is to learn about the effect of the study drug acetazolamide in individuals with Type 1 Diabetes. Specifically, whether acetazolamide provides benefits to the kidneys while minimizing any side effects of the drug. These changes will be measured by laboratory tests that tell us how well the kidneys are functioning.

Extended Bolus for Meals in a Closed-loop System
Recruiting
This study aims to evaluate whether the use of an extended bolus will improve glucose control with high-fat high protein meals using a closed-loop system. The new knowledge gained from this study may provide a method to allow for the proper administration of insulin over an extended period to mitigate the risk of prolonged hyperglycemia or early hypoglycemia.

Sotagliflozin to Slow Kidney Function Decline in Persons With Type 1 Diabetes and Diabetic Kidney Disease
Recruiting
Powerful new drugs that can prevent or delay end stage kidney disease (ESKD) - so called sodium-glucose cotransporter-2 inhibitors (SGLT2i) - are now available for patients with type 2 diabetes. Whether these drugs have similar effects in patients with type 1 diabetes (T1D) remains unknown because of the few studies in this population, due to concerns about the increase in risk of diabetic ketoacidosis (DKA, a serious, potentially fatal acute complication of diabetes due to the accumulation of s...

Commercial or Open Source Closed Loop Impact on Pregnancy Study
Recruiting
The goal of this observational study is to better understand what happens when pregnant people with type 1 diabetes (T1D) use automated insulin delivery (AID) systems. The main questions this study aims to answer are: * What are the maternal and neonatal outcomes with AID system use in pregnancy? * What are the glycemic outcomes with AID system use in pregnancy? * What are the behavioral and emotional outcomes with AID system use in pregnancy? Researchers will compare pregnant people who use c... Read More

BEAD-T1D: Building the Evidence to Address Disengagement in Type 1 Diabetes
Recruiting
Youth with public insurance underutilize diabetes care, particularly diabetes technology which is associated with improvement in diabetes-specific outcomes. Thus, we urgently need studies to understand and increase diabetes technology utilization. This proposed research will (1) improve representation of youth in the literature, (2) address the gap in knowledge of barriers and promoters in youth, and (3) identify and address factors associated with diabetes technology uptake and utilization.

Food Insecurity Reduction & Strategy Team
Recruiting
This study seeks to address the multifaceted challenges posed by food disparities and their negative consequences on health outcomes, via a comprehensive community health intervention program. Study objectives include: 1. To describe the social-demographic and clinical factors associated with food insecurity in the hospitalized diabetic population. 2. To design, implement and evaluate a nutrition program targeting the hospitalized diabetic population. The investigators will prospectively random... Read More

Type 1 Diabetes Extension Study
Recruiting
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... Read More
