Feasibility of Automated Insulin Delivery With an Interoperable Algorithm Using an Alternative Insulin Pump (BELIEVE)

4 de agosto de 2022 atualizado por: Imperial College London
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.

Descrição detalhada

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.

Experimental: Automated Insulin Delivery
The components of the automated insulin delivery system are the Dexcom G6 continuous glucose monitor (CGM), the InControl algorithm and an insulin pump (Ypsomed Ypsopump). The Dexcom G6 continuous glucose monitoring device is an approved device and is licensed to be used to inform insulin dosing decisions without confirmation. The algorithm (inControl 1.0) is approved when used embedded in the Tandem X2 insulin pump. We are using the algorithm for its intended purpose but are implementing it in a smartphone app to be installed in a compatible smartphone (Android). We are additionally assessing incremental benefit with the next software version of the algorithm. This will be the first time this updated software has been assessed in people with type 1 diabetes. The compatible insulin pump is a continuous subcutaneous insulin infusion device and is being used in line with its intended purpose, according to the manufacturer's instructions (YpsoMed Ypsopump).
