A Study to Evaluate the Effect of 1,25-Dihydroxyvitamin D3 to Treat Insulin Secretion and Muscle Strength in Pre-diabetics
Rochester, MN
The purpose of this study is to assess the effects of 1,25(OH)2D3 on insulin secretion by the pancreas and glucose utilization by skeletal muscle, as well as to determine the effects of 1,25(OH)2D3 on muscle strength in pre-diabetic subjects.

A Study to Evaluate Direct Measurement of Proinsulin Clearance in Humans
Rochester, MN
The purpose of this study is to determine if changes in fasting glucose and FFA concentrations alter 1st phase insulin secretion and proinsulin secretion in non-diabetic and pre-diabetic humans after determining the proinsulin volume of distribution, clearance rate and half-life in humans.

A Study to Evaluate the Effect of Fasting Free Fatty Acids and Fasting Glucose on Postprandial Glucose Metabolism
Rochester, MN
The purpose of this study is to determine if changes in fasting glucose and fasting free fatty acids (FFA) concentrations alter postprandial glucose metabolism in non-diabetic and pre-diabetic humans.

A Pilot Study Examining the Effect of Fasting Free Acid and Glucose Concentrations on Insulin Secretion
Rochester, MN
The purpose of this study is to determine if changes in fasting glucose and FFA concentrations alter 1st phase insulin secretion and proinsulin secretion in non-diabetic and pre-diabetic humans.

A Study of the Effects of a Hormone Called Glucagon in Glucose Metabolism in People with Pre-diabetes
Rochester, MN
The purpose of this study is to understand the effects of a hormone called glucagon in glucose metabolism in people with pre-diabetes.

Plasma Triglyceride Extraction by the Muscle
Scottsdale/Phoenix, AZ
Increased accumulation of fat into the muscles is associated with what is called insulin-resistant state, which is a pre-diabetic state. The purpose of this research is to find out how fat circulating in the blood following fat consumption is taken up by the muscles in healthy people as well as people that are insulin-resistant. The investigators are specifically interested in how a hormone called insulin is involved in this process. Findings from this research will contribute to our understanding of why insulin-resistant people have increased accumulation of fat in their muscles, and ultimately help to design appropriate interventions to prevent ...

Dietary Interventions in Prediabetes
Rochester, MN
Assessment of glucose metabolism and liver fat after 12 week dietary intervention in pre diabetes subjects. Subjects will be randomized to either high fat (olive oil supplemented),high carb/high fiber (beans supplemented) and high carb/low fiber diets. Glucose metabolism will be assessed by labeled oral glucose tolerance test and liver fat by magnetic resonance spectroscopy pre randomization and at 8 and 12 week after starting dietary intervention.

A Study to Evaluate the Effect of Metformin on Frailty in 12 Subjects (6 Metformin/6 Placebo in a Randomized Fashion)
Rochester, MN
The purpose of this study is to test whether chronic metformin administration will improve longevity of the cell, improve its machinery by reducing aging-related biochemical parameters, and improve physical performance as measured by short physical performance battery test.

Pilot Study to Quantify Insulin Synthesis and Secretion In Vivo
Rochester, MN
The purpose of this study evaluates a subset of people with isolated Impaired Fasting Glucose with Normal Glucose Tolerance (i.e., IFG/NGT) believed to have normal β-cell function in response to a glucose challenge, suggesting that – at least in this subset of prediabetes – fasting glucose is regulated independently of glucose in the postprandial period. To some extent this is borne out by genetic association studies which have identified loci that affect fasting glucose but not glucose tolerance and vice-versa.

A Study to Evaluate Molecular Mechanisms of Exercise Benefits in Insulin Resistant People
Rochester, MN
The aim of the study is to investigate the effects of a 3-month resistance exercise program (in people aged 50 to 75) on muscle mass, body composition, muscle strength, brain function and cognition, muscle efficiency processing blood sugar, the body’s ability to build muscle, and fat cells.
Earlier research has shown that exercise has significant benefits in preventing certain diseases and conditions such as diabetes, dementia, heart disease, and more. We also know from other research that resistance exercise (lifting weights) and aerobic exercise (running, biking, walking), improve metabolism through separate ways on the molecular level, also called “molecular pathways.” With ...

A Study to Evaluate the Effectiveness and Safety of Exenatide SR for Diabetes Prevention Following Kidney Transplantation
Rochester, MN; Scottsdale/Phoenix, AZ; Jacksonville, FL
The purpose of this study is to compare the rate of progression from prediabetes at 4 months to frank diabetes at 12 months (as defined by increase in HbA1C or fasting BS to diabetic range based on the ADA criteria) after transplantation in kidney transplant recipients on Exenatide SR + SOC vs. standard-of-care alone.

Dapagliflozin in Type 2 Diabetes or Pre-diabetes, and PRESERVED Ejection Fraction Heart Failure
Rochester, MN
The primary purpose of this study is to evaluate the impact of dapagliflozin, as compared with placebo, on heart failure, disease specific biomarkers, symptoms, health status and quality of life in patients with type 2 diabetes or prediabetes and chronic heart failure with preserved systolic function.

A Study to Evaluate the Effectiveness and Safety of Aramchol Versus Placebo in Subjects With NASH (ARMOR)
Rochester, MN
The purpose of this study is to evaluate the effect of Aramchol as compared to placebo on NASH resolution, fibrosis improvement and clinical outcomes related to progression of liver disease (fibrosis stages 2-3 who are overweight or obese and have prediabetes or type 2 diabetes).
