Diabetes Paid Clinical Trials in Massachusetts

This study aims to test the effectiveness of an evidence-based eating-disorder prevention program specifically targeted for individuals with Type 1 Diabetes (T1D) compared to an educational control group. The Diabetes Body Project (DBP), is an adaptation of the Body Project which is the only eating disorder prevention program to have repeatedly produced effects when evaluated by independent researchers, produced stronger effects than credible alternative interventions, and affected objective outcomes. DBP has been adapted slightly for individuals with T1D who are at ultra-high risk for eating disorders. The study aims to test the effectiveness of the DBP of reducing body image concerns and reducing eating pathology and improving glycemic control. Read Less

This study will evaluate the safety, tolerability and efficacy of VX-880 infusion in participants with Type 1 diabetes mellitus (T1D) and impaired awareness of hypoglycemia (IAH) and severe hypoglycemia. Read Less

To assess the efficacy of the REST model in facilitating adoption and sustained use of CGM, in older adults with Type 1 diabetes (T1D) or Type 2 Diabetes (T2D) on complex insulin regimens. To examine barriers and enablers for the implementation feasibility of the REST intervention model using a mixed-methods approach. To assess the impact of REST model on economic factors and quality of life measures. The goal of this study is to facilitate the adoption of continuous glucose monitoring (CGM) in older adults (≥65 years) with diabetes mellitus (DM) on complex insulin regimens, and additionally, to build a framework for sustained CGM use over time using a novel patient-centered model - the REST model.

This study is about testing whether exercise will improve fitness and lessen risk factors related to heart disease, diabetes, and obesity in Latina breast cancer survivors. Read Less

The goal of this observational study has the purpose of collecting biological samples from obese patients undergoing evaluation for weight loss by means of medical or endoscopic therapies; and of post bariatric surgery patients presenting with short- and long-term surgical complications. The aim is to enhance the overall understanding of the mechanisms leading to obesity, weight loss, failure to lose weight, and weight regain following treatment. Additional goals are to determine the efficacy of endoscopic and surgical procedures, to identify potential therapeutic targets and disease biomarkers that predict response to therapy. Read Less

The purpose of this study is to investigate if repeat bacillus Calmette-Guérin (BCG) vaccinations can confer a beneficial immune and metabolic effect in new onset pediatric Type 1 diabetes. Read Less

This study is designed to evaluate whether epigenetic markers in overweight men with type 1 diabetes (T1D) or type 2 diabetes (T2D) can be improved with a 3 month lifestyle intervention or program focused in glycemic intervention. Read Less

The PREDICT 3 study will build on previous research in over 2,000 individuals to further refine machine learning models that predict individual responses to foods, with the aim of advancing precision nutrition science and individualized dietary advice. The study incorporates both standardized and controlled dietary intervention, for the purpose of testing postprandial responses to specific mixed meals, in addition to a free-living period with a dietary record for measuring responses to a large variety of meals consumed in a realistic context, where the role of external factors (e.g. exercise, sleep, time of day) on postprandial responses may be determined. For the first time this PREDICT study is built on top of a commercial product which will allow access to a much larger group of participants who are already collecting large amounts of data through digital and biochemical devices that can contribute to science.

The purpose of this study is to conduct a two-arm, parallel-design, pragmatic randomized controlled trial of a patient portal intervention for diabetes, My Diabetes Care (MDC), to evaluate its effect on clinical outcomes. Read Less

Despite major technological advances, management of type one diabetes mellitus (T1D) remains suboptimal, putting millions of people at risk for immediate and long-term complications. After meals, a mismatch between carbohydrate absorption rate and insulin action typically leads to alternating periods of hyper- and hypoglycemia. A conceptually promising approach to control both problems is dietary carbohydrate restriction to reduce postprandial blood glucose changes and insulin needs. In a prior survey study, the investigators documented exceptional glycemic control (HbA1c 5.67%) and low acute complication rates among 316 children and adults with T1D consuming a very-low-carbohydrate diet. To test the feasibility of this approach, the investigators will conduct a randomized-controlled feeding study involving 32 adults and adolescents with T1D. Participants will be randomized to receive a very low carbohydrate vs. standard carbohydrate diet. Participants will be in the study for 12 weeks and receive all their meals by meal delivery.They will share continuous glucose monitoring data with the study team and be in close communication to adjust insulin doses as needed. All participants will have a screening visit, an individual or group education session, and 3 study visits to evaluate diabetes control and metabolic health. Some of these visits will have a fasting blood draw. Two of the visits will also comprise additional metabolic studies to assess glucagon response and brain function during hypoglycemia by magnetic resonance imaging (MRI). Participants will have IV catheters placed and receive IV insulin to drop blood glucose levels to 50 mg/dl for up to 30 minutes. The primary outcome will be HbA1c change from baseline. Secondary outcomes include detailed measures of glycemic variability, metabolic health, and quality of life. Read Less

Despite major technological advances, management of type one diabetes mellitus (T1D) remains suboptimal, putting millions of people at risk for immediate and long-term complications. After meals, a mismatch between carbohydrate absorption rate and insulin action typically leads to alternating periods of hyper- and hypoglycemia. A conceptually promising approach to control both problems is dietary carbohydrate restriction to reduce postprandial blood glucose changes and insulin needs. In a prior survey study, the investigators documented exceptional glycemic control (HbA1c 5.67%) and low acute complication rates among 316 children and adults with T1D consuming a very-low-carbohydrate (VLC) diet. Despite these promising preliminary results, the use of VLC diets for T1D remain controversial, because of their restrictive nature and theoretical concerns regarding growth, ketoacidosis and hypoglycemia risks and efficiency of glucagon treatment for hypoglycemia. Glucagon is used as a rescue medication during severe hypoglycemia and increases blood glucose levels by mobilizing liver glycogen stores. If these stores are depleted during carbohydrate restriction, glucagon response may be inadequate and put individuals at risk for refractory hypoglycemia. A physiologic study has shown a blunted but still adequate response to glucagon in n=10 participants after following a VLCD for 1 week. Longer-term studies have not been done. To test the hypotheses that glucagon response remains adequate while following a VLC diet in the longer term, the investigators will conduct a glucagon challenge in participants who are assigned to the VLC arm of a randomized-controlled feeding study in 32 young adults with T1D who will receive a VLC vs a standard diet for 12 weeks. After an overnight fast, twelve participants in the VLC arm will receive IV insulin to lower blood glucose levels to 60 mg/dL, followed by a glucagon injection and monitoring of blood glucose levels and other metabolic fuels.
