Clinical Trial Summary

This clinical study assesses the feasibility of implementing the inControl automated insulin delivery algorithm with Dexcom continuous glucose monitoring and a compatible insulin pump in adults with type 1 diabetes. It additionally provides pilot efficacy outcomes for interoperable automated insulin delivery.


Clinical Trial Description

Self-management of type 1 diabetes is challenging, efforts to optimise time spent in the target range can result in hypo- and hyperglycaemia. Structured education, glucose monitoring and advances in insulin delivery can increase time in range and reduce exposure to extremes of glucose and recent data confirm that automated insulin delivery can enable further increases in time spent in the target range of 3.9 to 10mmol/L (70 - 180mg/dL). The inControl algorithm, developed by TypeZero technologies is embedded in the Tandem X2 insulin pump and operates with the Dexcom G6 continuous glucose sensor and transmitter in a CE-marked and commercially available system (known as Control-IQ). This system optimises time in range compared with sensor-augmented pump therapy, and the improvement was maintained when participants were further randomised to predictive low glucose suspend or automated insulin delivery. The United States Food and Drug Administration has defined interoperable standards for automated insulin delivery systems, including the iCGM designation for continuous glucose sensors, the interoperable automated glycaemic controller designation, and alternate controller enabled insulin pumps. However, while standards have been defined, to date, interoperability of automated insulin delivery components has not been demonstrated. ;
