Phase 1 - Intervention
Some have speculated that the growing epidemic of Type 2 Diabetes (DM2) in children and adolescents may lead to the largest public health crisis of the next generation. To date, no effective treatment strategy has been demonstrated. The U.S. National Institute of Diabetes & Digestive & Kidney Diseases (NIDDK) sponsored TODAY (Treatment Options for Type 2 Diabetes inAdolescents and Youth) to address this need. The Pediatric Diabetes and Endocrinology Section was one of 15 sites in the nation awarded this grant to participate, along with Children's Hospital of Los Angeles, the University of Colorado Health Sciences Center, the University of Texas Health Sciences Center-San Antonio, Baylor University, St. Louis/Washington Universities, Case Western Reserve University, Children's Hospital Pittsburgh, Children's Hospital Philadelphia, State University of New York-Syracuse, Columbia University, Joslin Diabetes Center/Massachusetts General Hospital, and Yale University. Recruitment lasted from March, 2004 through February 2009, and the intervention phase of the study continued through February 28, 2011.
Metformin is currently the only medication approved by the U.S. Food and Drug Administration in the treatment of DM2 in youth. The primary aim of TODAY was to compare the safety and efficacy of three treatment regimens for DM2 in this age cohort: metformin + placebo, metformin + rosiglitazone (approved for DM2 in adults), and metformin + intensive lifestyle intervention. All patients had to meet eligibility criteria, complete a run-in period (which includes standard diabetes education) prior to randomization, and to receive treatment post-randomization for a total of 2-6 years.

Phase 2 - Long-term Outcomes
Recognizing the potential for a fuller understanding of the treatment for DM2 that began in youth, the NIDDK secured funding to transition participants to non-blinded, non-randomized standard diabetes care and management with follow-up through February 28, 2014. During this time, the study leadership will develop a longitudinal follow-up based on findings from the intervention phase of TODAY. We will monitor the effects of the different treatments from TODAY, describe the continued evolution of beta cell function, and describe the development of vascular complications and risk factors for vascular complications.
A separate set of TODAY study protocols relate to collecting blood and phenotypic information from more than 3,200 paticipants diagnosed with DM2 before age 18. Our Section is one of 24 sites collecting this data, which will be used to explore relationships between candidate genes and DM2, obesity, insulin resistance, and cardiovascular complications of insulin resistance.
