Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

An open-label, three-centers, controlled, randomized, and crossover study containing 14 days of baseline period with standard of care (SOC) therapy followed by two-sessions of 4-weeks home study phase with Diabeloop closed-loop (CL) system comparing the declaration of meals and the non-declaration of meals.

Diabeloop closed-loop glucose control session with the declaration of meals

Diabeloop software (an MPC-based glucose control algorithm) running on handset associated with the six-generation glucose sensor (Dexcom G6) and MEDISAFE WITH insulin pump.

Subjects are asked to declare their meals for 4 weeks.

A remote monitoring system is provided in closed-loop session.

Group Type ACTIVE_COMPARATOR

Dexcom G6 Continuous Glucose Monitoring

Intervention Type DEVICE

Collection of glucose data

MEDISAFE WITH External Insulin Pump

Intervention Type DEVICE

Insulin delivery

Diabeloop Software (Model predictive control)

Intervention Type DEVICE

Diabeloop software embeds a regulation algorithm to automatically regulate the patient's glycaemia. It takes as input glycaemia value received every 5 minutes from the CGM and patient inputs related to meals and physical activities and it calculates the amount of insulin to be delivered. It sends this information to the pump that automatically delivers this quantity.

Declaration of meals

Intervention Type OTHER

Patient inputs related to meals

Remote monitoring (Telemedicine)

Intervention Type OTHER

Remote follow up by care health providers team

Diabeloop closed-loop glucose control session without the declaration of meals

Diabeloop software (an MPC-based glucose control algorithm) running on handset associated with the six-generation glucose sensor (Dexcom G6) and MEDISAFE WITH insulin pump.

Subjects are asked to not declare their meals for 4 weeks.

A remote monitoring system is provided in closed-loop session.
