Type 1 Diabetes Clinical Trials in Boston, MA

T1D Pregnancy \& Me will partner with pregnant participants living with type 1 diabetes (T1D) in the United States to collect real-world data on management of T1D in pregnancy. This is a remote study where participants can complete online surveys and share device data (continuous glucose monitor (CGM) data and insulin data). Through the collection of CGM, insulin, and pregnancy outcome data, the study will provide important information to understand how diabetes is being managed during pregnancy. These data will provide much needed evidence to guide modern management of diabetes during pregnancy with a goal of improving care and outcomes. Read Less

The Gastroparesis Registry 4 (GpR4) is an observational study of patients with symptoms of gastroparesis (Gp) and functional dyspepsia (FD) with either delayed or normal gastric emptying. To better understand these disorders, this registry will capture demographic, clinical, physiological, questionnaire, and patient outcome data to characterize the patients and their clinical course. Participants will complete several questionnaires, complete a nutrient drink test and have a gastric emptying study. Read Less

The goal of this clinical trial is to test the effects of a ketogenic diet on the progression and control of type 1 diabetes in children with newly diagnosed diabetes. The main questions to answer are: * Does a ketogenic diet prolong the honeymoon period of type 1 diabetes? * Does a ketogenic diet improve diabetes control? * Is a ketogenic diet safe, acceptable and sustainable in children with newly diagnosed diabetes? * What are the microbiome, inflammatory and metabolic changes linking diet to β-cell function? Participants will receive a combination of free meals, groceries, micronutrient supplements, and intensive diet and diabetes education for 9 months. * Diabetes care devices will be connected for cloud-based data collection. * Bi-weekly data downloads and remote check-ins will assess dietary intake, satisfaction with diet and study procedures, and possible safety concerns. * During four study visits held at at baseline, 1, 5, and 9 months, an intravenous catheter (IV) will be placed for collection of 5 blood samples before and up to 2 hours after a liquid test meal (protein shake) to assess insulin response. A stool sample will also be collected to assess microbiome changes. * Children and their caregivers may be invited to participate in a semi-structured interview, and online questionnaires to assess their experience with the diet and diabetes care, general well-being and quality of life. * Children and their caregivers may be invited to participate in a follow-up visit to evaluate long-term effects after 24 months. Comparison will be made between a ketogenic vs standard diet. Read Less

The overall goal of the study is to create a standardized, stakeholder-informed system within EMRs, that will enable an equitable and regular prescription and documentation of advanced diabetes technologies. This will reduce racial disparities and generate an understanding of the reasons behind prescription decisions. The study will highlight the development and implementation an EMR-based Best Practice Advisory (BPA). The study will answer whether the EMR-based BPA can effectively reduce disparities. Additionally, it will explore why providers may not prescribe advanced diabetes technologies. Patients will also be surveyed to understand their perspectives on developing the EMR-based BPA.

Rationale: The accrual of data from the laboratory and from epidemiologic and prevention trials has improved the understanding of the etiology and pathogenesis of type 1 diabetes mellitus (T1DM). Genetic and immunologic factors play a key role in the development of T1DM, and characterization of the early metabolic abnormalities in T1DM is steadily increasing. However, information regarding the natural history of T1DM remains incomplete. The TrialNet Natural History Study of the Development of T1DM (Pathway to Prevention Study) has been designed to clarify this picture, and in so doing, will contribute to the development and implementation of studies aimed at prevention of and early treatment in T1DM. Purpose: TrialNet is an international network dedicated to the study, prevention, and early treatment of type 1 diabetes. TrialNet sites are located throughout the United States, Canada, Finland, United Kingdom, Italy, Germany, Sweden, Australia, and New Zealand. TrialNet is dedicated to testing new approaches to the prevention of and early intervention for type 1 diabetes. The goal of the TrialNet Natural History Study of the Development of Type 1 Diabetes is to enhance our understanding of the demographic, immunologic, and metabolic characteristics of individuals at risk for developing type 1 diabetes. The Natural History Study will screen relatives of people with type 1 diabetes to identify those at risk for developing the disease. Relatives of people with type 1 diabetes have about a 5% percent chance of being positive for the antibodies associated with diabetes. TrialNet will identify adults and children at risk for developing diabetes by testing for the presence of these antibodies in the blood. A positive antibody test is an early indication that damage to insulin-secreting cells may have begun. If this test is positive, additional testing will be offered to determine the likelihood that a person may develop diabetes. Individuals with antibodies 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.

The goal of this multi-center, randomized, cross-over study is to evaluate the safety and effectiveness of the Omnipod 5 SmartAdjust 2.0 System in individuals with type 1 diabetes. Study participants will complete about 5 in-person visits and be expected to treat their diabetes per their usual routine using the system at the lowest available target setting. Each participant will begin the study using either the Omnipod 5 SmartAdjust 2.0 System or the Omnipod 5 System for 4 weeks (Period 1) then switch to the opposite system for the next 4 weeks (Period 2). Everyone will use the Omnipod 5 SmartAdjust 2.0 System for the last 4-6 weeks (Period 3). During Period 3, participants will have a goal of administering no more than 3 meal or snack boluses per day.

This is a multi-center, prospective, non-interventional study that focuses on the long- term effects following participation in selected ITN new-onset Type1 Diabetes Mellitus studies with immunomodulatory agents (T1DM, T1D). This observational study will: * follow participants to determine how long they continue to produce insulin, and * will also assess how changes in the immune system over time relate to the ability to produce insulin. This information could help design better therapies for type 1 diabetes in the future. Read Less

Powerful new drugs that can prevent or delay end stage kidney disease (ESKD) - so called sodium-glucose cotransporter-2 inhibitors (SGLT2i) - are now available for patients with type 2 diabetes. Whether these drugs have similar effects in patients with type 1 diabetes (T1D) remains unknown because of the few studies in this population, due to concerns about the increase in risk of diabetic ketoacidosis (DKA, a serious, potentially fatal acute complication of diabetes due to the accumulation of substances called ketone bodies) observed with SGLT2i therapy in T1D. One of the few T1D studies conducted to date showed that implementing an enhanced DKA prevention plan can reduce the risk of DKA associated with the SGLT2i sotagliflozin (SOTA) to very low levels. In the present study, a similar DKA prevention program will be used to carry-out a 3-year trial to test the kidney benefit of SOTA in 150 persons with T1D and moderate to advanced DKD. After a 2-month period, during which diabetes care will be standardized and education on monitoring and minimizing DKA implemented, eligible study subjects will be randomly assigned (50/50) to take one tablet of SOTA (200 mg) or a similarly looking inactive tablet (placebo) every day for 3 years followed by 2-months without treatment. Neither the participants nor the study staff will know whether a person was assigned to taking SOTA or the inactive tablet. Kidney function at the end of the study will be compared between the two treatment groups to see whether SOTA prevented kidney function loss in those treated with this drug as compared to those who took the inactive tablet. The DKA prevention program will include participant education, close follow-up with study staff, continuous glucose monitoring, and systematic ketone body self-monitoring with a meter provided by the study. If successful, this study will provide efficacy and safety data that could be used to seek FDA approval of SOTA for the prevention of kidney function decline in patients with T1D and DKD. Read Less
