The study objective is to demonstrate that home use of Threshold Suspend (TS) is not associated with glycemic deterioration in pediatric patients with type 1 diabetes, as measured by change in A1C.
Multi-Center, Prospective, Observational Study of the TS (Threshold Suspend) Feature With a Sensor-Augmented Pump System in Pediatric Patients With Type 1 Diabetes
This study is a longitudinal, multi-center trial that aims to observe the Threshold Suspend (TS) feature with a sensor-augmented insulin pump in patients 7-15 years with Type 1 diabetes. The study will measure the change in A1C from baseline over a period of one year while subjects are wearing the study pump.
