Abstract

Background: Typically, closed-loop control (CLC) studies excluded patients with significant hypoglycemia. We evaluated the effectiveness of hybrid CLC (HCLC) versus sensor-augmented pump (SAP) in reducing hypoglycemia in this high-risk population. Methods: Forty-four subjects with type 1 diabetes, 25 women, 37?±?2 years old, HbA1c 7.4%?±?0.2% (57?±?1.5?mmol/mol), diabetes duration 19?±?2 years, on insulin pump, were enrolled at the University of Virginia (N?=?33) and Stanford University (N?=?11). Eligibility: increased risk of hypoglycemia confirmed by 1 week of blinded continuous glucose monitor (CGM); randomized to 4 weeks of home use of either HCLC or SAP. Primary/secondary outcomes: risk for hypoglycemia measured by the low blood glucose index (LBGI)/CGM-based time in ranges. Results: Values reported: mean?±?standard deviation. From baseline to the final week of study: LBGI decreased more on HCLC (2.51?±?1.17 to 1.28?±?0.5) than on SAP (2.1?±?1.05 to 1.79?±?0.98), P?
