Diabetes Clinical Trials

More than 100 million U.S. adults are now living with diabetes or prediabetes. Investigators still do not fully understand how diabetes develops and how the disease worsens. Insulin is a hormone that helps the body use sugar as a fuel and control blood-sugar levels. People with diabetes have problems making insulin. This is because their insulin-producing beta cells -in the pancreas-are damaged or destroyed. A biomarker is a biological molecule (such as DNA, RNA (the genetic material of cells) or protein) that is a sign of a normal or abnormal process, or of a condition or disease. A biomarker can be measured and found in blood and/or other body fluids (such as saliva and urine). Understanding the biology of beta cells could help find diabetes-related biomarkers. The discoveries from this research could help with early diagnosis of diabetes and lead to the creation of therapies for treating diabetes. Read Less

TACT3a is a double blind, placebo-controlled, randomized trial to test a novel therapy, edetate disodium-based chelation of environmentally acquired toxic metals, to reduce cardiovascular events including amputation in high-risk diabetic patients. Read Less

This study is a platform study designed to efficiently test multiple biomarkers to identify diabetic foot ulcers (DFUs) with a higher potential for healing versus not healing that ultimately could be applied at the point of care to drive personalized management decisions, and to better inform clinical trials of wound healing interventions Read Less

Nitric Oxide (NO) is an important molecule that is produced naturally in the body and that helps maintain healthy blood flow. Low availability of NO contributes to many diseases while administration of NO is therapeutic. In addition to being made naturally in the body, NO can be obtained through the diet via the Nitrate-Nitrite-NO cycle. Nitrate, which is abundant in green leafy vegetables and beetroot juice, is partially converted to nitrite by oral bacteria. The nitrate and nitrite are taken up into the blood and nitrite is converted into NO. Remaining nitrate in the blood is taken back up into the mouth by salivary glands and the cycle continues. Emerging studies suggest that the Nitrate-Nitrite-NO cycle may contribute to cardiovascular health. In addition, there have been many studies where dietary nitrate is given to increase NO and treat various conditions. The current study rests on the premise that the quality of the oral microbiome plays a major role in the Nitrate-Nitrite-NO cycle and hence cardiovascular health and the efficacy of dietary nitrate interventions. Investigators have begun to identify oral bacterial species that are effective nitrite producers as well as though that are nitrite depleters (those that interfere with nitrite production from nitrate). In laboratory experiments, certain bacterial species have been shown to block nitrate to nitrite conversion by other oral bacteria. These nitrite depleting species are found in a commercially available oral probiotic designed to improve oral health. The purpose of this study is to examine if use of the probiotic negatively affects the Nitrate-Nitrite-NO cycle. Nitrate to Nitrite conversion will be assessed by measuring plasma levels of nitrite before and after consumption of nitrate-rich beetroot juice. Dietary nitrate to plasma nitrite conversion will assessed at baseline and after one week of consumption of the probiotic or a placebo (follow-up). The primary hypothesis of this study is that participants that consume the probiotic will have lower nitrate to nitrite conversion at follow-up compared to baseline and that there will be no significant change in nitrate to nitrite conversion between baseline and follow-up for participants who consume the placebo. While this study does not aim to treat any specific disease, it is intended to elucidate a basic physiological function that may be relevant to cardiovascular health and certain NO-based therapeutics.

This study will conduct a two-arm randomized controlled trial to test the efficacy of a culturally tailored version of the NYU Caregiver Intervention (NYUCI) plus enhanced support (ES) through online chat groups (the NYUCI plus WeChat/Kakaotalk \[population social media app for Chinese/Korean\] peer support which we call the NYUCI-ES in reducing health risks for cardiometabolic disease among older Chinese and Korean American adults caring for relatives with ADRD. In collaboration with community organizations across the New York and northern New Jersey metropolitan area, we will enroll 300 caregivers of people with ADRD (150 Chinese and 150 Korean) in this study. Aim 1: Develop culturally adapted informational and educational materials about dementia and caregiving issues for social service providers of the intervention and for family caregivers. Aim 2: Test the hypothesis, H1: A counseling and support intervention (the NYUCI-ES) will significantly improve psychosocial factors such as depression, stress self-rated health and chronic disease management among Chinese and Korean-American ADRD caregivers and these changes will be mediated by improvement in social support. H1a: By the first (6- month) follow-up, the mediators (increases in social support, stress reaction) will improve significantly in the intervention group compared to baseline values and the control group. H1b: These improvements will be maintained, and lead to reduction in depressive symptoms, and improvement in self-reported health and chronic disease self-management by the 12-month follow-up compared to the control group. Aim 3: Test the hypothesis, H2: the NYUCI-ES will reduce biologic risk factors, including metabolic health (glycosylated hemoglobin) and inflammation (Oxidative stress, lipid metabolism, etc.) within 6 months of enrollment compared to baseline and a control group; these changes will be mediated through increases in social support and decreases in depressive symptoms and will be maintained at the 12-month follow-up. The public health significance of these findings will likely have an impact on health care policy for CGs from diverse underserved ethnic and cultural backgrounds, potentially reducing morbidity, and improving their quality of life.

The UAB Cardiovascular Research Biobank (CARBON) will be a resource that contains biological materials, such as DNA samples, in addition to health and personal information on a large number of people over time. It will be set up so that it can be used in the future as a resource for researchers undertaking a wide range of medical research. Read Less

Hypoglycemic complications are a major impediment to the maintenance of healthy glucose levels in persons with diabetes. The investigators recently completed a clinical pilot and feasibility study (GLIMPSE, NCT02690168), which identified a novel biomarker, glial acetate metabolism, that appears to predict the susceptibility to hypoglycemia. By providing an assay to predict hypoglycemic events and therefore diabetic complications, the development of this biomarker could significantly improve the treatment of persons with diabetes. The goal of this study is to determine the efficacy of our biomarker for predicting susceptibility to insulin-induced hypoglycemia. In order to accomplish this goal the investigatiors will pair our 13C magnetic resonance spectroscopy procedure to assess glial acetate metabolism, developed in the GLIMPSE study, with a hyperinsulinemic-hypoglycemic clamp procedure, developed in the HYPOCLAMP study (NCT03839511). The two procedures will be separated by a three day interval. The investigators will then correlate the participants' rates of glial acetate metabolism with their neuroendocrine responses to the hypoglycemic clamp. This proof of concept study will test the hypothesis that glial acetate metabolism is inversely proportional to the neuroendocrine response to hypoglycemia, that is, as glial acetate metabolism increases the neuroendocrine response will decrease.

Skeletal muscle metabolic health is critical for mobility and an underrecognized target of metabolic acidosis in chronic kidney disease. Impaired muscle mitochondrial metabolism underlies poor physical endurance increasing the risk of mobility disability. The proposed project will use precise in vivo tools to study the pathophysiology of poor physical endurance in a clinical trial treating metabolic acidosis among persons living with chronic kidney disease.
