Clinical Research in Type 1 and Type 2 Diabetes

David Nathan, M.D.

Dr. Nathan directs the MGH Diabetes Clinical Research Center, which focuses on the development and evaluation of innovative therapies for Type 1 and Type 2 diabetes and their complications. The Diabetes Clinical Research Center has played a leadership role in the conduct of several important clinical trials in diabetes, including the Diabetes Control and Complications Trial (DCCT) and its ongoing follow-up study, the Epidemiology of Diabetes Interventions and Complications (EDIC) study, which demonstrated the primacy of intensive metabolic control in preventing the development of complications in Type 1 diabetes; the Diabetes Prevention Program (DPP) which established the means of preventing Type 2 diabetes; the Look AHEAD study which is examining the means of preventing heart disease in Type 2 diabetes; the Immune Tolerance Network Study which explored islet transplantation as a treatment of Type 1 diabetes; the TODAY study, exploring the treatments of type 2 diabetes in children and adolescents, and most recently GRADE, a comprehensive comparative effectiveness study ot type 2 diabetes therapies. Other current single center studies promote the translation of laboratory results into new therapies and new techniques for islet transplantation, the development of an artificial pancreas for the treatment of type 1 diabetes, the immune basis of type 1 diabetes, cardiovascular disease prevention, and means of optimizing the care of Type 2 diabetes by primary care practitioners. Epidemiological studies in collaboration with the Framingham Heart Study, Baltimore Longitudinal Study of Aging, and Nurses and Physicians Health Studies explore the risk factors of diabetes and its complications and in particular the relationship between glycemia and heart disease. A host of genetics and pharmacogenetic and quality improvement studies are also ongoing.
