Filter by:The purpose of this trial is to assess the performance of an Artificial Pancreas (AP) device using the Portable Artificial Pancreas System (pAPS) platform for subjects with type 1 diabetes using an insulin pump and rapid acting insulin. This proposed study is designed to compare closed-loop control with or without optimization of initialization parameters related to basal insulin infusion rates and insulin to carbohydrate (I:C) ratios for meals and snacks.
This is a two-period study of participants with type 1 diabetes mellitus (T1DM). In each period, participants will receive once daily injections of stable dose LY2605541 or insulin glargine for 28 to 35 days followed by procedures to look at how the body uses or stores fats and sugars. Participants will continue to use meal time insulin throughout the study. Healthy participants will also enroll in the study. They will not receive any study medication.
City of Hope National Medical Center, located in Duarte, CA, is hosting a clinical study on islet cell transplantation, an experimental procedure being evaluated as a treatment for patients with type 1 diabetes. Islet cell transplantation involves taking insulin-producing cells from organ donors and transplanting them into the liver of a patient with diabetes. Once transplanted, the islets produce insulin, which can improve blood sugar control and eliminate the need to inject insulin or use an insulin pump. Anti-thymocyte globulin (ATG) and alemtuzumab (Campath) are anti-rejection medications that work by decreasing a patient's T-cells. T-cells are special white blood cells that recognize and destroy unwanted things like infections but can also attack transplanted cells and organs. Reducing the number of T-cells at the time of transplant may protect islets and improve long-term transplant success. In previous research studies, islet transplantation has been successful in reducing low blood sugar episodes, improving overall blood sugar control, and in some cases, allowing patients with type 1 diabetes to stop taking insulin. The purpose of this study is to determine if islet cell transplantation using ATG or alemtuzumab, along with additional medications to prevent the body from rejecting the transplanted cells, is a safe and effective treatment for type 1 diabetes. Study participants may receive up to three islet transplants and will be followed for five years to monitor blood sugar control, islet transplant function, and changes in quality of life.
The aim of this study is to evaluate the effect of a single session of aerobic plus resistance exercises on the vascular function of patients with type 1 diabetes mellitus. The investigators hypothesize that a single aerobic exercise session would promote greater benefit in vascular function of patients with type 1 diabetes, as compared with the resistive exercise session.
The purpose of this study is to determine whether Telecare can be used for efficient management of adults with Type 1 Diabetes Mellitus using insulin pump, in lieu of frequent clinic visits.
To test the function and safety of the Medtronic Overnight Closed Loop (OCL) System in a closely monitored 12 hour overnight inpatient study. Once the safety of the device has been validated we will move the study to an outpatient diabetes camp setting. The camp setting will allow us to obtain pilot efficacy and safety data in a "real-life" environment. We plan to compare the subject control nights to the subject nights on the OCL system to assess the percent of sensor glucose readings in the target range of 70-150 mg/dl. Based on previous research, we anticipate that the use of the OCL system will contribute to a greater percentage of sensor glucose readings in the target range.
This clinical trial is a feasibility study to assess the performance of an Artificial Pancreas (AP) device using the Artificial Pancreas System (APS©) platform for subjects with type 1 diabetes using rapid-acting insulin as well as preprandial inhaled insulin (Technosphere® Insulin Inhalation System by MannKind Corporation). The goal of this proposed study is to explore the feasibility of using multiple insulin delivery routes in order to mimic the physiology of both first- and second-phase insulin secretion. The intent is to exploit the rapid action achieved by inhaled insulin to compensate for part of the meals and utilize the conventional subcutaneous route for management of basal insulin and as second-phase meal-related insulin.
The objectives of this outpatient research study are (1) to assess the ability of this automated system to be operated by a subject with limited professional oversight; (2) to assess whether the new devices (Dexcom Gen 4 sensors, Motorola ES400 smart phone, iDex pump controller) will reduce the frequency of hardware and data communication lapses seen in the previous system; and (3) to measure the degree of glucose control achievable with this automated system. The system will adjust blood glucose by administering insulin and glucagon. Insulin is a hormone that lowers blood glucose and will be given nearly continuously during this study. Glucagon raises blood glucose and will be automatically administered during hypoglycemia. Both are natural hormones made by people without diabetes. Each subject will have four devices placed on his abdomen: two Omnipod insulin pumps, one for delivering insulin and one for delivering glucagon, and two Dexcom G4 glucose sensors for measuring glucose. The two sensors will feed glucose data into Motorola smart phone master controller, which will calculate the correct amount of insulin or glucagon to deliver. The system will then send the command to the correct Omnipod through the iDex pod controller. In this new system, the research subject will be able to monitor the progress of the study by use of the smart phone graphical user interface. The subject will have a companion with him/her during the entire study for safety purposes. Both the subject and companion will complete a training course on how to treat diabetic emergencies and how to operate the system. A study physician and technician will be in the hotel during each study and will be monitoring the study via a cloud-based data communication system. These studies will be carried out in a hotel setting.
The primary objectives of this study are to compare the difference in glycosylated hemoglobin (HbA1c) from baseline to Month 6 using Hylenex recombinant preadministration in continuous subcutaneous insulin infusion (CSII) versus standard CSII and to evaluate the safety of Hylenex recombinant preadministration, including local tolerability, adverse events, and hypo- and hyperglycemia rates.
We will perform blood sugar studies to assess changes in metabolic (biochemical processes that occur within us) profiles associated with high blood sugar and diabetes.
