Study Details

Study Description

Brief Summary

The goal of this study is to assess the functionality of an integrated predictive low glucose suspend system designed to minimize the incidence and duration of hypoglycemia by suspending insulin delivery if hypoglycemia is projected.

Condition or Disease Intervention/Treatment Phase
  • Device: t:slim insulin pump with predictive low glucose suspend
Phase 1

Detailed Description

This protocol is designed to test the functionality of a predictive low glucose suspend system under supervised conditions where basal insulin rates are manually increased until a system generated suspension occurs. The study will collect data that will be used for planning a pivotal study, and the study data are intended to be used to support a Premarket Approval (PMA) application.

Arms and Interventions

Arm Intervention/Treatment
Experimental: t:slim insulin pump with predictive low glucose suspend

To assess the functionality of a predictive low glucose suspend (PLGS) system that uses CGM values to suspend basal insulin delivery when hypoglycemia is predicted as well as resume basal insulin delivery once Continuous Glucose Monitoring (CGM) values begin to increase.

Outcome Measures

Primary Outcome Measures

  1. Suspension of Insulin Delivery [8 hours between 9pm and 5am]

    To test functionality of the system

  2. Restoration of insulin delivery [8 hours between 9pm and 5am]

    To test functionality of the system

  3. Agreement between algorithm-recommended pump action [8 hours between 9pm and 5am]

    To test functionality of the system

Other Outcome Measures

  1. Duration of insulin suspension [8 hours between 9pm and 5am]

    To test functionality of the system

  2. Continuous Glucose Monitoring (CGM) glucose nadir [8 hours between 9pm and 5am]

    To test functionality of the system

  3. Reference blood glucose [8 hours between 9pm and 5am]

    To test functionality of the system
