Brief Summary

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

The study will be conducted in crossover trial, with two 72-hour hospitalization separated by a period Wash-out of at least one week. Each hospitalization is a period of treatment. According to randomization, patients will be provided with either Diabeloop system or the usual system.

In both treatment periods:

* patients in a situation of sedentarity or physical activity, will be equipped with ActiGraph (measuring motricity) and a ActiHeart ( measuring heart rate)
* meals and physical activities will be similar in both periods
* the same blood glucose meter will be used throughout the duration of the study.
* the capillary blood glucose will be performed : before bolus and 2 hours after a meal, before exercise, in case of hypo or hyper-glycemic episodes and when the patient and / or investigator deem it necessary.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Usual System (open-loop)

In open loop, the patient will be provided with its usual pump and a CGM. To estimate rest and physical activity in patients being sedentary situation ( Centers : Caen, Nancy \& Strasbourg) or in situations of physical activity ( Centers : CHSF Marseille and Besancon ) , the usual system will be complemented by an accelerometer " ActiGraph " and a " ActiHeart " heart rate monitor.

Group Type OTHER

Continuous Glucose Monitoring

Intervention Type DEVICE

Accelerometer and heart rate monitor

Intervention Type DEVICE

Monitoring and measurement of physical activity

Meals

Intervention Type DIETARY_SUPPLEMENT

Calibrated meals for all patients and outstanding dinners for patients being in outstanding meals situation (Centers : Grenoble, Toulouse, Montpellier)

DIABELOOP System (closed-loop)

In the closed loop, the patient's pump will be replaced by the Diabeloop system consisting of insulin pump Cellnovo driven by remote control augmented by Diabeloop software and connected to the CGM.
