We want to provide people living with diabetes with an intelligent therapeutic system to regulate blood glucose. This project was initiated in 2011 by the CERITD (Centre d’Études et de Recherches pour l’Intensification du Traitement du Diabète) in collaboration with the CEA LETI. After the success of the clinical trials in 2014, we created Diabeloop to bring the project to market and make it available to the largest number of people. Since spring 2021, DBLG1 System, the first automated insulin delivery device, is being marketed in several European countries: Germany, Italy, Spain, Switzerland, the Netherlands and France.
