The Accu-Chek Insight insulin pump can now be used in hybrid closed-loop mode in Switzerland

  • People with diabetes in Switzerland now have the opportunity to use the Accu-Chek Insight insulin pump with the automated insulin delivery (AID) system from Diabeloop.
  • The Accu-Chek Insight insulin pump from Roche is the first pump with a pre-filled cartridge that can be operated in loop mode.
  • The pairing of the Accu-Chek Insight insulin pump, which has been a companion for people with diabetes since 2014, with the self-learning algorithm DBLG1, aims to automate and personalise diabetes management for better therapy outcomes and true relief.

Basel, 3 May 2021 - Roche today announced that the Accu-Chek Insight insulin pump can now be used with the automated insulin delivery (AID) system from the French MedTech company Diabeloop in Switzerland. People with type 1 diabetes now have the opportunity to use an insulin pump that features a pre-filled insulin cartridge and a spectrum of infusion sets to suit individual needs in a CE-labelled hybrid-closed loop system. The new set-up is a first result of the recently established partnership between Roche and Diabeloop allowing for convenience and personalisation in insulin pump therapy while contributing to more effective diabetes management and improving therapy outcomes.

Using artificial intelligence, the hybrid closed-loop system from Diabeloop mimics pancreatic functions and enables automated blood glucose control. Its core element is a unique self-learning algorithm, DBLG1, hosted on a dedicated handset and now connected via Bluetooth technology to the Accu-Chek Insight insulin pump and a continuous glucose monitor (CGM). Every five minutes, the DBLG1 algorithm analyses the patient’s glucose levels and automatically calculates the needed dose of insulin in real time, taking into account the individual physiology, history and data inputs for meals and physical activity.

“The Accu-Chek Insight insulin pump is designed for easy and convenient insulin pump therapy. Its users appreciate the sleek and intuitive design, the possibility to set a very low basal rate and above all the pre-filled cartridge for more comfort,” said Marcel Gmuender, Global Head of Roche Diabetes Care. “With the ability to connect our well-established Accu-Chek Insight insulin pump with a hybrid closed-loop system, we are taking a great step towards the personalised treatment of diabetes in Switzerland.” Study data demonstrate a significant improvement in glycaemic control, a reduction in hypoglycaemic risk in adults with type 1 diabetes, and more time in range using the AID algorithm from Diabeloop1,2 which is seen to be positively associated with long-term health3. “For people with diabetes, the hybrid closed-loop system helps to simplify everyday treatment by reducing the constant burden associated with dozens of calculations and therapeutic decisions to be taken in order to control the blood glucose levels day and night,” concluded Marcel Gmuender.

The launch of the innovative diabetes management solution in first countries across Europe and now in Switzerland marks Roche’s first step in the field of automated insulin delivery (AID) and is a milestone in its strategy of integrated Personalised Diabetes Management (iPDM).
