Diabetes Paid Clinical Trials in Massachusetts

The scientific goal of this study is to examine the effects of a ketogenic diet on hypoglycemia tolerance and brain function in people with type 1 diabetes mellitus (T1D) and to clarify the mechanistic role of ketones in this process. Glycemic management of T1D is typified by alternating periods of hyper- and hypo-glycemia. Because brain metabolism under usual conditions depends on glucose, acute hypoglycemia leads to immediate complications including impaired cognitive function and a counter-regulatory hormone response. Recurrent hypoglycemia is associated with functional and structural changes in the brain and contributes to the cognitive decline observed in individuals with diabetes. The state of nutritional ketosis (as it occurs during fasting or when following a ketogenic [very low carbohydrate] diet) may protect against these acute and chronic complications. As the body relies on fat metabolism, ketone bodies build up and provide an alternative fuel for the brain. Studies during hypoglycemia have shown better cognitive function and less hypoglycemia symptoms in the setting of nutritional ketosis or with ketone administration. This physiological benefit may have special relevance for people with T1D who experience hypoglycemia frequently. To date, no mechanistic studies have examined brain effects of nutritional ketosis in T1D; nor have any trials explored the potential relevance of this for diabetes care. Read Less

A Randomized, Multi-Center, Pivotal Efficacy and Safety Study Evaluating the EndoBarrier System for Glycemic Improvement in Patients with Inadequately Controlled Type 2 Diabetes and Obesity, the STEP-1 Study. A multi-center, double-blinded, randomized, sham-controlled trial to evaluate the safety and effectiveness of the EndoBarrier System plus moderate intensity lifestyle and dietary counseling compliant with 2019 ADA Standard of Care as compared to a sham control receiving moderate intensity lifestyle and dietary counseling. Both the treatment and sham group will practice medical management compliant with STEP-1 Study Guidelines. Patients will be randomized 3 (EndoBarrier):1 (Sham). Read Less

The T1D Exchange Registry is a research study, conducted over time, for individuals with type 1 diabetes and their supporters. Participants volunteer to provide their data for research (for example, by answering questions in annual surveys). Once enrolled, Registry participants have the opportunity to sign up for other studies on various topics related to type 1 diabetes. To participate, you will be asked to: Read and sign an online informed consent form Take a survey describing specific demographic and type 1 diabetes management information Update your information annually Periodically opt in for additional research opportunities (if you choose), i.e. taking new surveys or uploading health device data Read Less

A phase 2a trial randomized, double-blind, placebo-controlled, parallel group trial to determine whether NMN administration improves DKD, as indicated by a significantly greater reduction in UACR compared with placebo administration. Eligible participants will be randomized to receive either 1000 mg NMN or placebo twice daily. Read Less

This study is being done to better understand whether meal replacements can be an effective tool for weight loss and treatment of elevated blood sugars in people with obesity/overweight and diabetes/pre-diabetes who have a low income. Read Less

The aim of this study is to determine if suvorexant can help treat the severity of insomnia in midlife women who are pre-diabetic. Read Less

To collect, preserve, and/or distribute annotated biospecimens and associated medical data to institutionally approved, investigator-directed biomedical research to discover and develop new treatments, diagnostics, and preventative methods for specific and complex conditions. Read Less

Canagliflozin is an oral drug which is currently approved for use in patients with type 2 diabetes by the US Food and Drug Administration (FDA). Canagliflozin acts by increasing salt and sugar loss in the urine, and has shown to protect heart, kidney, and blood vessel function in patients with type 2 diabetes. However, it is unknown how canagliflozin protects the kidneys from disease. Therefore, this study plans to learn more about how canagliflozin works to protect against diabetic kidney disease in adults with type 2 diabetes. This study will use state-of-the-art kidney imaging, kidney biopsies and detailed testing of kidney function to determine the mechanisms of protection afforded by canagliflozin. Read Less

This trial will determine the clinical effectiveness of polygenic risk score testing among patients at high genetic risk for at least one of six diseases (coronary artery disease, atrial fibrillation, type 2 diabetes mellitus, colorectal cancer, breast cancer, or prostate cancer), measured by time-to-diagnosis of prevalent or incident disease over 24 months.

RADIANT is a network of 14 clinical sites and several laboratories dedicated to the study of atypical diabetes. The objective of this study is to define new forms of diabetes and the unique mechanisms underlying these forms of atypical diabetes. The specific aims are to: Identify and enroll individuals and families with undiagnosed rare and atypical forms of diabetes. Determine the etiologic basis of the metabolic disorder among individuals and families with novel forms of rare and atypical diabetes. Understand the pathophysiology of individuals and families with novel forms of rare and atypical forms of diabetes. Read Less

The hypothesis for this study is that women with different physiologic subtypes of gestational diabetes (GDM) (insulin secretion deficit vs. insulin sensitivity deficit) will differ in their glycemic responses to meals with different portions of dietary macronutrients. Investigators will determine GDM subtype based on glucose and insulin levels taken at multiple time points during an oral glucose tolerance test. Participants will consume two meals with different macronutrient content while wearing a continuous glucose monitor which will allow investigators to assess the glycemic response to the meals.
