Medtronic Minimed Overnight Closed-Loop System

Completed · Not applicable

Conditions studied: Type 1 Diabetes Mellitus, Autoimmune Diabetes, Juvenile-Onset Diabetes, Diabetes, Mellitus, Type 1

In brief

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.

You may qualify if…

• To be eligible for the study, a subject must meet the following criteria:
• Clinical diagnosis of type 1 diabetes and using daily insulin therapy for at least one year and a Medtronic insulin infusion pump for at least 3 months The diagnosis of type 1 diabetes is based on the investigator's judgment; C peptide level and antibody determinations are not required.
