Filter by:The purpose of this study is to determine how Humulin-R regular insulin affects the body's ability to feel low blood sugar (hypoglycemia) when delivered intranasally compared to placebo in subjects with Type 1 Diabetes (T1D) with hypoglycemia awareness. The study will use continuous glucose monitoring (CGM) to collect this information. The study drug or placebo will be administered using an intranasal device.
The "Open Artificial Pancreas System (OpenAPS)" was designed to quickly spread technology and knowledge about the construction of artificial pancreas systems to patients with diabetes without awaiting clinical regulatory approval. OpenAPS is based on a privately shared software programs and available insulin pumps and glucose sensors. OpenAPS includes a "decision making" algorithm, which issues adaptions of basal rates to insulin pumps, which represents all fundamental aspects of closed loop artificial pancreas systems. The present study aims to compare the accuracy and performance of a self-constructed OpenAPS system with the approved hybrid closed loop system Medtronic Minimed 670G. While wearing the Medtronic Minimed 670G in automode, study participants will wear an OpenAPS system in parallel, which does calculate basal rate adaptions based on continuous glucose monitoring data and its respective algorithm. The investigators aim to recruit 15 participants in an open label, single-center, single-arm, observational study. Insulin injection will only be provided by the Medtronic 670G HCL system (Basal rate insulin). The OpenAPS system will be worn contemporaneously, calculate recommended basal rate insulin adjustments but will not inject insulin. The maximum treatment period will be 2 weeks per patient.
To use an enhanced continuous glucose monitor (CGM) experience, including an automated CGM-electronic health record (EHR) data integration system, proactive interventions, and gamification techniques, to increase CGM use among publicly-insured youth with type 1 diabetes (T1D).
During this study, the investigators will perform a collection of biological and device samples (blood, catheters, insulin) in order to investigate the causes of catheter obstructions in patients with type 1 diabetes treated by implanted insulin pumps using intra-peritoneal delivery. This multi-centre study is interventional with minimal constraints. After an inclusion visit, blood samples and an insulin sample from pump reservoir will be collected. During the following year, if a peritoneal catheter is blocked or changed, the explanted catheter and new blood and insulin samples will be collected for examination of the catheter obstruction and search for patient- or insulin-related reasons for obstructions. In this study, 140 patients will be investigated.
During this study, we propose to assess the utility of Continuous Glucose Measurements (CGM) in a group of Type 1 diabetic patients treated with an implanted insulin pump. Patients will participate in two period of 3 months separated by a 3 months washout. During one period, they will use CGM to adapt their insulin therapy while during the other period, they will manage their diabetes with their usual capillary blood glucose meter. We except to observe an increase of time spent in glucose safe range when using CGM.
