A Randomised Trial Investigating the Pharmacokinetic and Pharmacodynamic Properties of Faster-acting...
DiabetesDiabetes Mellitus1 moreThis trial is conducted in Europe. The aim of the trial is to investigate the pharmacokinetic (the exposure of the trial drug in the body) and pharmacodynamic (the effect of the investigated drug on the body) properties of faster-acting insulin aspart in subjects with Type 1 diabetes.
Timing of Pre-meal Insulin Versus Accurate Carbohydrate Counting in Youth With Type 1 Diabetes
Type 1 DiabetesThe investigators are hoping to figure out how youth with type 1 diabetes can best control their blood glucose levels after meals, by determining whether accurate carbohydrate dosing or the timing of the bolus is more important. There is evidence to suggest that each strategy is important for blood glucose control. Unfortunately, for some people, prebolusing is difficult, because they may not know how much they are going to eat. To give an exact dose of insulin 20 minutes before a meal can be difficult. In this study, the investigators would like to show that taking even just part of the insulin bolus 20 minutes before the meal is preferable to waiting until mealtime and taking the entire bolus. To do this, the investigators will have 24 patients in the study, who will each spend 4 mornings at The investigators clinic. The order of the visits will be selected randomly. The visits will include: taking full bolus at mealtime, taking full bolus 20 minute before mealtime, taking ½ bolus at mealtime, and taking ½ bolus 20 minutes before mealtime. At each visit, the person will eat the same meal, but the timing and amount of the bolus will be different. The investigators will measure the blood glucose levels with a blood glucose meter, and also with a laboratory test called YSI. The investigators will also be measuring the glucose levels under the person's skin with a continuous glucose monitor. The investigators will compare the area under the curve for the different visits, as well as the glucose levels at different points after the meal.

Performance of Continuous Glucose Monitoring Systems at Altitude
Diabetes MellitusType 110 healthy volunteers will undergo the controlled lowering of their blood glucose level at sea level and a simulated altitude of 8,000 feet, to test the hypothesis that continuous glucose monitoring system measurement of blood glucose is as accurate at altitude as at sea level.
Closed Loop System With Pramlintide Versus Exenatide
Type 1 DiabetesPost-prandial hyperglycemia occurs despite meticulous carbohydrate counting and rapid acting insulin therapy. Furthermore, this occurs even in the setting of the closed loop system. Currently the algorithm used for calculating the glucose-responsive insulin delivery cannot respond in a timely fashion to the glucose absorption resulting from a meal. In diabetes, there is paradoxical immediate post-prandial hyperglucagonemia that results in immediate post-prandial hyperglycemia. Amylin deficiency and/or dysregulated GLP-1 seems to be the etiology. Pharmacologic replacement of these hormones alleviates immediate post-prandial hyperglycemia in diabetes. With this protocol, the investigators would like to optimize treatment of T1DM by physiologic replacement of hormones in addition to insulin and in the process also optimize the insulin algorithm. This is a paired, randomized, and controlled comparison of pramlintide and insulin versus exenatide and insulin Vs insulin monotherapy using the ePID closed-loop system for insulin delivery. The investigators will stratify the study subjects into the following sub-groups of 5 subjects of 22-30 years old, 4 subjects of 18-21 years old, 4 subjects of 16-18 years old. The investigators would also begin the study with the 21-25 year patient sub-group and then transition to the other sub-groups after evaluating all the safety issues. 22-30 year old ones would be considered as an adult subset, 18-21 year olds would be considered pediatric subset according to the guidelines of FDA's Center for Devices and Radiological Health (CDRH) and 16-18 year olds are considered typical pediatric population. At this time, Spanish-speaking subjects will not be recruited because Medtronic Minimed as yet does not have any literature in Spanish that may used in explaining the study to this group of patients. When in the future Medtronic is able to provide us with the appropriate Spanish literature, the investigators will at that time amend the protocol to include this group of subjects.
Use of Exenatide and Pramlintide to Decrease Post-prandial Hyperglycemia
Type 1 DiabetesThe main purpose of the study is to determine the effects of 16 weeks of adjunctive pramlintide or exenatide use on glycemic control in Type 1 Diabetes.
A Pilot Study of Continuous Subcutaneous Pramlintide Infusion Therapy in Patients With Type 1 Diabetes...
IDDMThis research project will investigate the effects of pramlintide (Symlin) given by continuous subcutaneous (under the skin) infusion throughout the day and night, along with meal doses similar to those injected during conventional pramlintide (Symlin) treatment, delivered using a second insulin pump, in subjects with inadequately controlled type I diabetes mellitus who are already using insulin pump therapy. Study participants will wear two pumps for a four month period, taking insulin in their usual manner and pramlintide (Symlin) in a similar basal/bolus fashion. Continuous glucose monitors will be worn on three occasions during the study to assess blood glucose responses to continuous pramlintide (Symlin) treatment.
