Trial to Reduce IDDM in those at Genetic Risk (TRIGR)Pregnant women who: have type 1 diabetes OR the father of this baby has type 1 diabetes OR a full sibling to this baby has type 1 diabetes.

Type 1 Diabetes Genetics Consortium  (T1DGC)The T1DGC has completed enrollment for the affected sibling pair families phase of the study. We would like to thank all of participants worldwide who helped the study reach this monumental goal.

We are continuing to recruit trios (father, mother, and a child with type 1 diabetes), as well as cases (with type 1 diabetes) and controls (no history of type 1 diabetes) from populations with a low prevalence of the disease only as we have adequate numbers of Caucasians of European origins. In Asia Pacific, this includes individuals from countries such as India and Thailand. In North America, this includes Mexican American and African American individuals.

TrialNet-MMF/DZB (TrialNet)This study is no longer recruiting patients. Persons who had developed type 1 (insulin dependent) diabetes within the last three months and who are between the ages of 12 and 35 were eligible to participate.

TrialNet Natural History Study (TrialNet)To participate in the screening phase of the Natural History Study, you must be: (1) 1 to 45 years of age and have a brother, sister, child, or parent with type 1 diabetes; OR (2) 1 to 20 years of age and have a cousin, aunt, uncle, niece, nephew, half-sibling, or grandparent with type 1 diabetes. In general, type 1 diabetes is assumed if it developed before age 40 and required insulin injections within a year of diagnosis.

The Rituximab Study (TrialNet)This study is no longer recruiting patients. People were eligible for this study if they:
  • were diagnosed with type 1 diabetes within the past 3 months.
  • were 12 to 45 years of age.
  • had blood tests that showed that their body was still making insulin.
  • had antibodies in their blood that are present in people with type 1 diabetes.
  • were willing to use birth control and take urine pregnancy tests at every visit (if female and sexually active).
  • agreed to manage their diabetes daily. This means checking blood sugar 3 to 4 times each day and taking multiple insulin injections or using an insulin pump.

Nutritional Intervention to Prevent Diabetes  (TrialNet)This study is no longer recruiting patients. Pregnant women in their third trimester of pregnancy and infants 6 months of age or younger were eligible to enroll if there was a family history of type 1 diabetes.

Oral Insulin Study  (TrialNet)To be screened for the study, you must be: (1) 1 to 45 years of age and have a brother, sister, child, or parent with type 1 diabetes; OR (2) 1 to 20 years of age and have a cousin, aunt, uncle, niece, nephew, half-sibling, or grandparent with type 1 diabetes.

CTLA-4 Ig (Abatacept) in Recent Onset Diabetes (TrialNet)To be screened for the abatacept study, research volunteers need to be: (1) 6 to 45 years old; and (2) diagnosed with type 1 diabetes less than 3 months ago. Screening tests, including blood tests, will help decide who can participate in this study.

Description

Trial to Reduce IDDM in those at Genetic Risk (TRIGR)This randomized, double blinded intervention study will compare the incidence of predictive autoantibodies and clinical diabetes in the two treatment groups. The intervention will compare a casein hydrolysate with a standard cow milk based formula. Breast feeding is encouraged and supported in this study. The baby would be fed the study formula only if mom decides to bottle feed, wean from breast feeding before 8 months of age, or supplements breast feeding with formula.

Type 1 Diabetes Genetics Consortium  (T1DGC)The consortium is a group of diabetes researchers from around the world who have come together to collect samples and information from families with type 1 diabetes.

TrialNet Natural History Study (TrialNet)TrialNet is a network of 18 Clinical Centers working in cooperation with screening sites throughout the United States, Canada, Finland, United Kingdom, Italy, Germany, Australia, and New Zealand. This network is dedicated to the study, prevention, and early treatment of type 1 diabetes. The Natural History Study is one of the studies TrialNet will perform. This study will screen individuals who are close relatives of people with type 1 diabetes to identify those at risk for developing the disease. Individuals at risk will be offered the opportunity for further testing to determine their risk of developing diabetes over the next 5 years and to receive close monitoring for the development of diabetes. Participants in the Natural History Study may be offered the opportunity to enter into prevention or early treatment studies when these become available.

Trial to Reduce IDDM in those at Genetic Risk (TRIGR)This randomized, double blinded intervention study will compare the incidence of predictive autoantibodies and clinical diabetes in the two treatment groups. The intervention will compare a casein hydrolysate with a standard cow milk based formula. Breast feeding is encouraged and supported in this study. The baby would be fed the study formula only if mom decides to bottle feed, wean from breast feeding before 8 months of age, or supplements breast feeding with formula.

TrialNet Natural History Study (TrialNet)TrialNet is a network of 18 Clinical Centers working in cooperation with screening sites throughout the United States, Canada, Finland, United Kingdom, Italy, Germany, Australia, and New Zealand. This network is dedicated to the study, prevention, and early treatment of type 1 diabetes. The Natural History Study is one of the studies TrialNet will perform. This study will screen individuals who are close relatives of people with type 1 diabetes to identify those at risk for developing the disease. Individuals at risk will be offered the opportunity for further testing to determine their risk of developing diabetes over the next 5 years and to receive close monitoring for the development of diabetes. Participants in the Natural History Study may be offered the opportunity to enter into prevention or early treatment studies when these become available.

The Environmental Determinants of Diabetes in the Young  (TEDDY)The primary objective(s) of this multi-center, multi-national, epidemiological study will be identification of infectious agents, dietary factors, or other environmental exposures that are associated with increased risk of autoimmunity and type 1 diabetes. Factors affecting specific phenotypic manifestations such as early age of onset or rate of progression, or with protection for the development of type 1 diabetes will also be identified.

The TEDDY study will recruit and enroll individuals, including obtaining informed consent from parents prior to or shortly after birth, obtain genetic and other samples from neonates and parents, and prospectively follow selected neonates throughout childhood or until development of islet autoimmunity or type 1 diabetes. The clinical center will collect and transmit genetic and other samples and familial and clinical data as delineated in the manual of operation to the Data Coordinating Center.

A cohort of children with elevated genetic risk for type 1 diabetes will be established by screening newborns from the general population and from families with first-degree relatives diagnosed with the disease.
