External shot of Yale

Yale is one of twenty-two Type 1 Diabetes TrialNet International Clinical Centers at the forefront of type 1 diabetes research. Led by our Clinical Center Director and Principal Investigator, Kevan Herold, MD, the TrialNet team at Yale is dedicated to preventing type 1 diabetes and stopping disease progression by preserving insulin production before and after diagnosis.

Kevan Herold, MD

My background and research are in translational immunology. I am interested in understanding the basis for autoimmune diseases and developing new therapies based on our understanding of disease mechanisms. My focus has largely been in the field of autoimmune Type 1 diabetes. The work encompasses basic laboratory work understanding the regulation of autoreactive T cells to clinical trials that involve novel therapeutics. As part of these studies I have also been very interested in analysis of beta cell function in Type 1 diabetes.

Research Studies

Risk Screening Risk Screening for Relatives

If you have a relative with T1D, you may be eligible for risk screening that can detect the early stages of T1D years before symptoms appear. More

Monitoring Monitoring

Depending on your risk screening results, you may be eligible for monitoring. We’ll monitor you for disease progression and let you know if you become eligible for a study. More

Prevention Study ATG Prevention Study (STOP-T1D)

TrialNet is testing a low dose of the immunotherapy drug anti-thymocyte globulin (ATG) to see if it can delay or prevent type 1 diabetes (T1D) in people ages 12 up to 35 who have a 50% risk of clinical diagnosis (Stage 3) within 2 years. Risk is defined by having two or more autoantibodies and abnormal blood sugar (Stage 2), plus at least one high-risk marker (based on test results). In an earlier TrialNet study for people newly diagnosed with T1D, low-dose ATG preserved insulin production and improved blood sugar control for 2 years. Details

Long Term Long-Term Follow-up

If you are diagnosed with T1D while participating in one of our prevention studies, we’re still here for you. You can continue to receive personal monitoring while helping us learn more. More

Newly Diagnosed Tolerance Using Plasmid (TOPPLE) Study: Phase 1

TrialNet is testing the safety of a new treatment, NNC0361-0041, in adults diagnosed with type 1 diabetes (T1D) in the past 48 months. This is a Phase 1 study, which means it is the first time this treatment is being tested for safety in people. If this study results in no safety concerns, we plan to conduct a larger study to see if this same treatment can slow down or stop T1D in people at high risk, before clinical diagnosis. More

Newly Diagnosed JAK Inhibitors Newly Diagnosed Study (JAKPOT T1D)

TrialNet researchers are testing two different treatments – abrocitinib and ritlecitinib – to see if either or both can preserve insulin production in people (ages 12-35) newly diagnosed with type 1 diabetes (Stage 3 T1D). Abrocitinib and ritlecitinib are in a new class of autoimmune treatments called Janus kinase (JAK) inhibitors. Details

Newly Diagnosed Rituximab-pvvr / Abatacept Newly Diagnosed Study (T1D RELAY)

TrialNet is testing rituximab-pvvr and abatacept in people (ages 8-45) who were newly diagnosed with type 1 diabetes (T1D) to learn if using both treatments, one after the other, maintains the body’s ability to make insulin. By adding abatacept after rituximab-pvvr, researchers predict more people will experience prolonged beta cell function during and possibly after treatment. Details
