Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to test an insulin management system ("Control-to-Range (CTR) system") in an inpatient setting to see if the system is safe and effective enough to test in a future at-home study. The system includes (1) a DexCom Seven Plus Continuous Glucose Monitoring (CGM) device that measures the blood sugar, (2) a laptop computer that determines how much insulin is needed, and (3) an Insulet OmniPod insulin pump that delivers the insulin. The study will include two hospital stays consisting of meals and exercise scenarios. Both hospital stays will be for 24+ hours during the day and night. The study will include about 50 individuals at 7 clinical centers in the United States, France, Israel, and Italy.
