Dallas Diabetes and Endocrine Center

Dallas Diabetes and Endocrine Center (DDEC) is a premier medical practice and clinical research facility based in Dallas, Texas, specializing in the treatment and study of metabolic disorders. Founded by Dr. Julio Rosenstock, the center is globally recognized for its extensive involvement in pivotal clinical trials for nearly all major diabetes medications approved over the last three decades. DDEC provides comprehensive patient care for endocrine conditions while serving as a high-volume site for Phase 1 through Phase 4 clinical trials. In 2021, the research operations of DDEC were acquired by Velocity Clinical Research, integrating the site into a global network of clinical trial locations. The center remains a critical partner for major pharmaceutical companies in the development of novel GLP-1 receptor agonists, SGLT2 inhibitors, and advanced insulin formulations.
