Tandem Predictive Low Glucose Suspend Inpatient Feasibility Study
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.

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. |

To assess the functionality of a predictive low glucose suspend (PLGS) system that uses Continuous Glucose Monitoring (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.
