Study Summary
The purpose of this study is to use an Advisory/Automated Adaptive (AAA) or Closed-Loop Control (CLC) system for insulin delivery in adults with Type 1 Diabetes (T1DM) in an outpatient setting to evaluate the system's ability to significantly improve blood glucose levels. A component of this study evaluated AAA or CLC Control overnight only in 5 consecutive overnights in a cross-over trial with sensor-augmented pump therapy occurring prior to or following CLC overnight. Another component of this study planned evaluating if the AAA Control system run on the Diabetes Assistant (DiAs) system can prevent hypoglycemia during and following exercise more efficiently during a 40 hour trial this part of the trial was not conducted due to a preference for overnight only configuration in pilot testing. This protocol represents a culmination of prior clinical trials in development of this AAA system and benefits from the synthesis of those components.
Primary Outcome
For subjects participating in consecutive overnight control, will assess time in range (80-140mg/dL) overnight in closed loop control compared to sensor-augmented pump therapy.
Interventions
- DEVICE Overnight CLC
- DEVICE Sensor-Augmented Pump Therapy (SAP)
