NCT00419562
Type 1 diabetes (T1D) is an autoimmune disease. This means that the immune system (the part of the body which helps fight infections) mistakenly attacks and destroys the cells that produce insulin (islet cells found in the pancreas). As these cells are destroyed, the body's ability to produce insulin decreases. There is evidence suggesting that repeated oral administration of an autoantigen (the same protein that the immune system is reacting to) may introduce a protective immunity and cause the immune system to stop its attack. An earlier, large scale study was done to see if oral insulin could delay or prevent the development of Type 1 diabetes in relatives at risk for developing Type 1 diabetes. The overall results showed that for the entire study population, oral insulin did not delay or prevent Type 1 diabetes. However, an analysis that was done after the conclusion of the trial suggested a potential beneficial effect in a subgroup of participants. The participants who seemed to benefit from oral insulin had higher levels of insulin autoantibodies which are directed against insulin itself ( called mIAA). The Type 1 Diabetes TrialNet study group will further explore the potential role of oral insulin to delay or prevent Type 1 diabetes in a similar group of people. The study will also include a secondary group of individuals at different levels of risk than those in the primary cohort to gather information for future studies.

NCT01083108
Background: * Bariatric surgery is the most effective way to achieve significant, long-term weight loss. It has also been shown to be an effective therapy for obese individuals with type 2 diabetes: more than 70 percent of patients no longer need medications for diabetes after surgery. This resolution of diabetes is predominately caused by marked weight loss resulting in improved insulin sensitivity. However, the beneficial effects of bariatric surgery on type 2 diabetes cannot be accounted for entirely by weight loss, because many bariatric surgery patients have resolution of diabetes within 1 week following bariatric surgery, even before they lose a clinically significant amount of weight. * One possible reason for the rapid resolution of diabetes after bariatric surgery .is that during the first week after surgery, patients can eat very little (about 300 Calories per day). It is well known that reducing calories to this level improves diabetes. Another possibility is that changes in the flow of food through the intestines may improve diabetes. Evidence for this comes from the observation that patients after gastric bypass have better glucose levels than those who have gastric banding. Researchers are interested in determining how much of the improvement in diabetes in the first week after Roux-en-Y gastric bypass (RYGBP) surgery is due to restricting calories, and how much is due to other factors, such as bypassing the upper part of the small intestine. Objectives: * To determine the change in total body insulin sensitivity after RYGBP compared to caloric restriction without surgery. * To study possible reasons for improvements in diabetes after RYGBP. Eligibility: \- Individuals 18 to 60 years of age who have a body mass index (BMI) greater than 35 and have type 2 diabetes. Design: \- This is not a randomized study, and patients will not receive bariatric surgery as part of this study. Two groups of patients will be studied: those scheduled for RYGBP surgery and those not undergoing surgery. * RYGBP Surgery Participants: * Up to 3 weeks before surgery, participants will spend 2 nights and days at the Vanderbilt University Clinical Research Center or the NIH Clinical Center for testing to learn about how their bodies handle sugar and use energy. During the 5 days prior to these tests, participants will be asked to not take diabetes medications, and will check blood sugar at least twice a day. * From 8 days before surgery, participants will begin an 800 Calorie per day liquid diet to prepare for surgery. * After surgery and discharge, participants will be readmitted to the Clinical Research Center at Vanderbilt or NIH for further tests and diet monitoring. Diabetes medications may be adjusted or stopped altogether based on the results of the tests. * Non-surgery Participants: * Participants will spend 2 nights and days in the NIH Clinical Center for testing to learn about how their bodies handle sugar and use energy. During the 5 days prior to these tests, participants will be asked to not take diabetes medications, and will check blood sugar at least twice a day. * After the tests, participants will begin an 800 Calorie per day liquid diet for 8 days. * After 8 days, participants will be readmitted to the Clinical Center at NIH for 1 week of further tests and a 300 Calorie per day diet. Diabetes medications may be adjusted or stopped altogether based on the results of the tests.

NCT03439072
This is a non-inferiority, multi-center, randomized, controlled, single-blind, two-way crossover efficacy and safety study in subjects with Type 1 diabetes mellitus. The study involves two daytime clinical research center (CRC) visits with random assignment to receive G-Pen™ glucagon 1 mg during one period and Lilly Glucagon 1 mg during the other. Each daytime visit is preceded by an overnight stay in the CRC. In the morning of the inpatient study visit, the subject is brought into a state of hypoglycemia through IV administration of regular insulin diluted in normal saline. After a hypoglycemic state with plasma glucose \< 50 mg/dL is verified, the subject is administered a dose of G-Pen or Lilly Glucagon via subcutaneous injection. Plasma glucose levels are monitored for up to 180 minutes post-dosing, with a value of \>70.0 mg/dL within 30 minutes of glucagon administration indicating a positive response. After 3 hours, the subject is given a meal and discharged when medically stable. After a wash-out period of 7 to 28 days, subjects return to the CRC, and the procedure are repeated with each subject crossed over to the other treatment. A follow-up visit as a safety check is conducted 2-7 days following administration of the final dose of study drug.
NCT01781975
Type 1 diabetes mellitus (T1DM) results from the autoimmune destruction of insulin-producing ß cells. Although exogenous insulin is widely available, it is not possible for affected individuals to consistently achieve euglycemia with current technology, and thus they are at risk for devastating long-term complications. This phase II study is designed to evaluate the safety and efficacy of imatinib mesylate as a novel therapy for new-onset T1DM. Imatinib is a first-in-class tyrosine kinase inhibitor. This study will explore the potential role of short-term therapy with imatinib to induce tolerance and possibly lead to a durable long-term remission of T1DM.
NCT00279305
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks the insulin-producing beta cells in the pancreas. Without these beta cells, the body cannot maintain proper blood glucose levels in response to daily activities such as eating or exercise. With fewer insulin producing cells blood glucose increases, causing hunger, thirst, and unexplained weight loss. By the time these symptoms develop, 80-90% of a person's beta cells have already been destroyed. However, this also means that between 10-20% of these cells remain that continue to produce insulin. Scientists have learned that two types of immune cells, B cells and T cells, are involved in causing type 1 diabetes. T cells are responsible for attacking and destroying the beta cells that make insulin. Although they don't attack insulin producing cells, B cells may be what trigger the T cells to attack. This study will investigate the use of rituximab to see if it can help lower the number of immune B cells thereby preventing the destruction of any remaining insulin producing beta cells that remain at diagnosis. Rituximab is approved by the Food and Drug Administration (FDA) for the treatment of a condition called B-lymphocyte lymphoma. Its effects on the immune system are well understood through its use in organ transplantation. Research has shown that rituximab might be helpful in treating other conditions caused by T cells and B cells, including type 1 diabetes. The goal of this study is to find out if rituximab can preserve residual insulin secretion and prevent further beta cell destruction in type 1 diabetes.
