Clinical Trials

The purpose of this study is to demonstrate the performance of the Guardian™ Sensor (3) with an advanced algorithm in subjects age 2 - 80 years, for the span of 170 hours (7 days).

The study aims to determine if a popular dextrose candy alternative yields a similar glycemic curve compared to the standard oral Dextrose solution used in the Oral Glucose Tolerance Test. Additionally the study aims to determine if substituting the traditional oral dextrose solution used in the Oral Glucose Tolerance Test for a candy alternative yields a higher level of patient satisfaction among children ages 10-21 in the Mayo Clinic Cystic Fibrosis Center. 

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.

The goal of this study is to determine the role of postprandial glucagon suppression and insulin secretion in the progression of glucose intolerance in people with diabetes-associated variation in TCF7L2.
