About

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.

Full 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.

Enrollment: 10 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Diagnosis of type 1 diabetes requiring insulin therapy for at least 12 months
• Insulin pump therapy for at least 6 months
• Age ≥18.0 years
• Subject demonstrates stable insulin regimen including basal rates, insulin sensitivity factor and insulin:carbohydrate ratio for at least 3 months

Exclusion criteria

• Pregnant (female subjects must have negative urine or serum pregnancy screening test)
• Severe hypoglycemia resulting in seizure or loss of consciousness in the month prior to enrollment
• Diabetic ketoacidosis in the month prior to enrollment
• A current condition that would prevent the use of a CGM sensor or insulin pump, or in the judgment of the investigator is a contraindication to study participation
• Use of acetaminophen during study participation
• Current use of any medication intended to lower glucose other than insulin including naturaceuticals, oral or non-insulin injectable medications

Trial design

10 participants in 1 patient group

t:slim insulin pump with predictive low glucose suspend

Experimental group

Description:

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.
