Medtronic Minimed Overnight Closed-Loop System
Not Recruiting
Trial ID: NCT01881009
Purpose
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.

Eligibility
Inclusion Criteria:
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.
- Age 10.0 - 35 years
Exclusion Criteria:
The presence of any of the following is an exclusion for the study:
- Diabetic ketoacidosis in the past month
- Hypoglycemic seizure or loss of consciousness in the past 3 months
- History of seizure disorder (except for hypoglycemic seizure)
- History of any heart disease including coronary artery disease, heart failure, or
arrhythmias
- Cystic fibrosis
- Current use of oral/inhaled glucocorticoids, beta-blockers or other medications, which
in the judgment of the investigator would be a contraindication to participation in
the study.
- History of ongoing renal disease (other than microalbuminuria).
- Medical or psychiatric condition that in the judgment of the investigator might
interfere with the completion of the protocol such as:
- Inpatient psychiatric treatment in the past 6 months
- Uncontrolled adrenal disorder
- Abuse of alcohol
- Pregnancy
Intervention(s):
device: Hybrid Closed-loop System
device: Sensor-augmented pump
