Special Diabetes Program: Consortia, Networks & Centers

The Special Diabetes Program has enabled the creation of unique, innovative, and collaborative research consortia and clinical trials networks to advance progress on the prevention, treatment, and cure of type 1 diabetes. These consortia, networks, and centers are programs funded to create communities of researchers focused on answering complicated scientific questions in the field of type 1 diabetes research. The goal of these large, high-impact research efforts is to promote progress in type 1 diabetes research that could not be achieved by a single laboratory.

These efforts span a continuum from basic research to identify promising therapeutic targets and agents, to pre-clinical studies testing agents in animal models, to clinical trials in people with or at risk for type 1 diabetes. These consortia and networks, as well as the research resources that they are generating, expand the scope and power of research efforts by making technological developments and tools available to the broad diabetes scientific community and beyond.

The research consortia, networks, and centers listed on this page are or have been supported, in part or full, by the Special Diabetes Program. For more information on these research programs and other research efforts, and the scientific accomplishments resulting from these efforts, please visit the Reports and Planning page.

Type 1 Diabetes Mouse Resource (T1DR): The goal of the T1DR is to enhance existing investments in animal models of type 1 diabetes research by facilitating the development and sharing of these unique resources. It provides a source for distribution of mouse strains related to type 1 diabetes and its complications to the scientific community.

Clinical Research Consortia and Networks

Clinical Islet Transplantation Consortium: The CIT is developing and implementing a program of single- and/or multicenter clinical studies, accompanied by mechanistic studies, in islet transplantation with or without accompanying kidney transplantation, for the treatment of type 1 diabetes.

Collaborative Islet Transplant Registry (CITR): CITR is expediting progress and promoting safety in islet/beta cell transplantation through the collection, analysis, and communication of comprehensive and current data on all islet/beta cell transplants performed in North America. Annual reports with data from islet transplant programs are available on the CITR website.

Diabetes Research in Children Network (DirecNet): DirecNet is a multicenter clinical research network investigating the use of technology advances in the management of type 1 diabetes in children and adolescents. Study information, protocols, datasets, publications, and slidesets are available on the DirecNet website.

Diabetic Retinopathy Clinical Research Network (DRCR.net): The DRCR.net is a collaborative, nationwide network of eye doctors and investigators conducting clinical research of diabetes-induced retinal disorders. Resources posted on the DRCR.net website include datasets, policies, procedures, publications, and presentations.

Epidemiology of Diabetes Interventions and Complications (EDIC): EDIC is studying the clinical course and risk factors associated with the long-term complications of type 1 diabetes, using the cohort of patients who participated in the landmark Diabetes Control and Complications Trial (DCCT). See the NIDDK Central Repositories website for access to DCCT/EDIC resources: https://www.niddkrepository.org/studies/edic/.

Genetics of Kidneys in Diabetes (GoKinD): GoKinD is a repository of DNA and clinical information from adults with long-term type 1 diabetes, with or without kidney disease. More than 3,500 participants provided blood and urine samples for biochemical and genetic analysis in the first phase of the GoKinD study. See the NIDDK Central Repositories website for access to GoKinD resources: https://www.niddkrepository.org/studies/gokind/.
