SportGuard: Prevention of Hypoglycaemia With Predictive Insulin Suspend Using Sensor Augmented Insulin Pump in Children
Study Details
Study Description
Brief Summary
The aim of the study is to prove whether the use of the SmartGuard feature of the MiniMed system significantly reduces hypoglycemic excursions and thus provide proactive protection to the user.

Detailed Description
This is randomized two-arm parallel controlled open label study that will be conducted at two sites, in Slovenia and Israel. It is an investigator initiated pediatric clinical study.
Study will be conducted on pediatric population during two weeks, following a 3 day Run-in period that will allow the patients to get familiar with study device and CGM (SmartGuard OFF).
Patients will be asked to continuously wear the study device for 14 days, which will be set up by study staff according to randomization in the specific group. They will be provided with a diary for entering their daily activity, food consumption (carb count) and eventual adverse events.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Suspend Before Low feature turned ON MiniMed™ 640G system with the "Suspend Before Low" feature turned ON; continuously set on at 3,6 mmol/L (65 mg/dL). "Suspend On Low" Alert and "Resume Basal Alert" for the SmartGuard group should be set OFF. Administered intervention: Medtronic MiniMed™ 640G system |
Device: Medtronic MiniMed™ 640G system
The MiniMed™ 640G system is indicated for the continuous delivery of insulin, for continuous or periodic monitoring of glucose levels in the fluid under the skin, with a feature for a prediction of low or high glucose episodes.

| Active Comparator: Suspend Before Low feature turned OFF MiniMed™ 640G system with the "Suspend Before Low" and "Suspend On Low" features are both turned OFF; "Alert On Low" is set at 65 mg/dL (3,6 mmol/L). "Resume Basal Alert" should be set OFF as well. Administered intervention: Medtronic MiniMed™ 640G system |
