Condition: Diabetes
Investigator: Robin Goland, MD
Status: Currently Recruiting
A future without Type 1 Diabetes (T1D) starts with you. Get screened! Thanks in large part to T1D family members, we understand T1D as a disease that progresses in three distinct stages. This new definition in conjunction with TrialNet's Pathway to Prevention screening, allows for earlier detection and intervention.

Condition: Diabetes
Investigator: Joshua Cook, MD, PhD
Status: Currently Recruiting
We are conducting a research study on how insulin controls blood sugar in both healthy people and those at risk of type 2 diabetes.

Participants will undergo a…
Condition: Diabetes
Investigator: Jacqueline Lonier, MD
Status: Currently Recruiting
In PRECIDENTD, we hope to learn which diabetes medications work best to reduce the risk of heart and kidney disease in people with type 2 diabetes. People with type 2 diabetes are twice as likely to have heart disease or a stroke compared to someone who does not have diabetes, and they are likely to have heart disease or stroke at a younger age. People with…

Investigator: Joshua Cook, MD, PhD
Status: Currently Recruiting
We are recruiting volunteers, aged 18-70, for a research study on the buildup of excessive liver fat ("fatty liver disease") in people with or at risk for type 2 diabetes because their bodies are resistant to the actions of the blood sugar-lowering hormone, insulin. To do this, we seek to temporarily induce or accentuate insulin resistance in 14…
