Fully Closed Loop Glucose Control With a Bihormonal Artificial Pancreas in Adults With Type 1 Diabetes: An Outpatient, Randomized, Crossover Trial
To demonstrate the performance and safety of a bihormonal (insulin and glucagon) artificial pancreas in adults with type 1 diabetes.
RESEARCH DESIGN AND METHODS
In this outpatient, randomized, crossover trial, two-week fully closed loop glucose control (artificial pancreas therapy) was compared to two-week open loop control (patient’s normal insulin pump therapy with a glucose sensor if they had one).
RESULTS
Twenty three patients were included in the analysis. Median (IQR) time in range (70-180 mg/dL [3.9-10 mmol/L]) was significantly higher during closed loop (86.6% [84.9-88.5]) compared with open loop (53.9% [49.7-67.2]; p<0.0001).
CONCLUSIONS
Compared to insulin pump therapy, the bihormonal artificial pancreas provided superior glucose control, without meal or exercise announcements, and was safe in adults with type 1 diabetes.
