EkiYou-Study-2 is an interventional multicenter randomised controlled clinical investigation according to EU 2017/745. It is conducted in 154 adults with diabetes and treated by multiple daily insulin injections that will be followed for 6 months.

After a randomization, participants will receive for 6 months EkiYou V2 Digital Therapy that will help them to estimate their daily bolus and basal insulin doses. This device weekly adjusts insulin parameters including : basal insulin dose, insulin to carb ratios and correction factor.

The control group will stay with their standard care, and after the first three months of control period, they will receive EkiYou V2 for the last three months.

The aim of this study is to examine the performance of the EkiYou V2 Digital Therapy compared with conventional methods for people with diabetes treated with multi-injections as part of a basal-bolus regimen. We also aim to assess the level of satisfaction and user experience with the EkiYou application, as well as the quality of life of study participants.

Participants of the study must be adults treated with multiple daily insulin injections in a basal/bolus insulin regimen and users of a continuous glucose monitor (CGM). The study involves 3 visits (including the inclusion visit), for a total duration of 6 months for each participant.

The study participants will be randomized in two groups and will receive EkiYou V2 either at inclusion or at the second visit after three-months control period.

EkiYou V2 device is a new version of the previously CE-Marked device EkiYou V1. It is a decision support that include the following features to participants:

• Carbohydrate counting through an extensive food database with more than 200k items.
• Bolus calculation based on their meal, physical activity and blood glucose.
• Bolus correction advice.
• Long-acting insulin reminders and automatic periodic titration.
• Insulin-to-carb ratios and correction factor automatic adjustment.
• Connection to CGM devices

Participants will also respond to ePRO questionnaires during the clinical investigation to collect data on their quality of life and their satisfaction.
