Study Summary

This study was designed to test a closed-loop control-to-range artificial pancreas (AP) system. There are two phases to this study. Within Phase 1, there were various stages of this study starting with 0-3 weeks of practice with CGM. This was followed by 2 weeks using the study pump together with CGM known as sensor augmented pump (SAP) therapy. This was used as a baseline and followed by 2 weeks of overnight only closed loop control (CLC) and 2 weeks of 24/7 CLC. During the CLC weeks, insulin was administered by the AP system. Phase 2 continued with only 14 patients - physician’s choice. These 14 patients used the CLC system 24/7 for five additional months.
