What it reported doing in 2025
ResearchClinical Research Type 1 DiabetesSansum Diabetes Research Institute (SDRI) is a nonprofit organization dedicated to improving the lives of people impacted by diabetes through clinical research, education, and specialized patient care. During 2025, SDRI initiated 13 clinical research trials involving 197 individual participants. These studies evaluated new technologies, medications, and treatment approaches intended to improve diabetes management and health outcomes.Research activities included automated insulin delivery systems, continuous glucose monitoring, inhaled insulin therapies, GLP-1 medications, ketone and lactate monitoring, digital health tools, and other emerging diabetes technologies. SDRI collaborated with leading diabetes technology and pharmaceutical companies to conduct research that supports the development of safer and more effective treatments for people living with diabetes.During 2025, SDRI also launched Screen & Support, a community-based type 1 diabetes early detection program. Through autoantibody screening, education, monitoring, and follow-up care, the program identifies children and adults at increased risk for developing type 1 diabetes before symptoms occur. Earlier identification helps reduce the likelihood of diagnosis during diabetic ketoacidosis (DKA), provides families with education and support, and expands access to therapies that may delay progression to insulin-dependent disease. SDRI also continued leading the California Type 1 Diabetes Screening Collaborative to expand early detection efforts throughout California.Clinical Research Type 2 DiabetesSDRI continued research designed to improve treatment options and clinical outcomes for individuals living with type 2 diabetes. During 2025, the SDRI participated in studies evaluating automated insulin delivery systems, continuous glucose monitoring technologies, and emerging therapeutic approaches intended to improve glycemic control while reducing the burden of diabetes management.Research findings contributed to the growing body of evidence supporting advanced diabetes technologies for adults with type 2 diabetes and included participation from diverse populations to improve the applicability of study findings across communities.
Operating model

- Mixed. Its operating money came from several sources; no one source provided a clear majority.
- Distribution model
- Direct operator. The filing allocates 100% of reported program-service expenses outside its grant, affiliate-payment, and member-benefit lines. This expense classification does not rule out separately announced grant awards.
- Includes noncash contributions: Reported contributions include donated property or goods.
The verdict
STRONG - A large share of available resources goes toward mission work and the filed numbers largely add up. Fundraising costs are high for each dollar raised and expenses are high relative to revenue.
