About

This is a multicenter feasibility study. Up to 85 subjects will be enrolled in the study. The goal of the study is to demonstrate that the Hybrid Closed Loop (HCL) System is safe to be used in an even larger study outside of hospital.

Full description

Subjects that have met eligibility criteria will undergo treatment with the hybrid closed loop system under various experimental conditions.There is no statistically powered study hypothesis testing.

The investigational centers will be encouraged to include subjects of different ethnicities including Hispanic, Native American, and African-American.

The study is anticipated to last no more than 12 months from investigational center initiation to finalization of all data entry and monitoring procedures. Subjects are expected to participate for approximately 1- 2 months.
