September 22, 2026 — Type 1 Diabetes TrialNet (TrialNet), the world’s leading international research network dedicated to type 1 diabetes prevention, has launched the ASCEND T1D Study.

June 1, 2026 – Type 1 Diabetes TrialNet (TrialNet), the world’s leading international research network dedicated to the prevention of type 1 diabetes, today announced the appointment of Michael Haller, MD, as Chair and Carmella Evans-Molina, MD, PhD, as Vice Chair.

A new clinical study is testing rezpegaldesleukin to see if it can help people recently diagnosed with type 1 diabetes continue to make insulin by resetting the body's natural immune balance. Rezpegaldesleukin has already shown promising results in clinical trials for other autoimmune diseases, including atopic dermatitis and lupus.

As we begin a new year, we are excited to share TrialNet’s progress in 2025 and our plans for the year ahead.

We also want to take this opportunity to thank our participants, their families, and our research teams. Your commitment helps us learn more about how T1D progresses and contributes to advances in preventing and delaying type 1 diabetes (T1D).

From camper to director of the largest camping association serving people with diabetes

When Lisa Gier attended her first diabetes camp at Camp Hodia (a mix of Idaho and diabetes) at age 10, she had no idea she would build an amazing career in camping.

As we begin a new year, it’s the perfect time to celebrate our accomplishments. We recently spoke with TrialNet Chair Kevan Herold, MD, to get his insights on the past year and plans for the year ahead. Dr. Herold is a professor of immunobiology and medicine at Yale University, one of 17 TrialNet Clinical Centers at the forefront of type 1 diabetes research.
