Filter by: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.
This clinical trial is a randomized trial including a 3-month single-arm part and a 6-month extension phase. - Following randomization between the 1st group and 2nd group, a 2-week baseline period in open-loop for 148 adults and 30 adolescents will be performed. Patients will receive the standard of care treatment including their usual subcutaneous insulin pump augmented with continuous glucose measurement with Dexcom G6. - Then, a 3-month study phase will be performed during 12 weeks: - 1st group (111 adults randomized from 148 adults and 30 adolescents) will receive the treatment via the Closed-loop System (closed-loop condition). - 2nd group (37 adult controls randomized from 148 adults) will receive the standard of care treatment including their usual subcutaneous insulin pump augmented with continuous glucose measurement with Dexcom G6 (open loop condition). - An extension period of 6 months with the Closed-loop System (closed-loop condition) will be performed at the end of the study phase for all patients enrolled.
Feasibility study, comparing experimental treatment (DBLHU closed-loop system) with reference treatment (Low Glucose Predictive Suspend system) in 7 patients going through a series of N-of-1 trials. Each N-of-1 trial consists in a prospectively planned, multiple crossover study in a single individual. Two blocks of two periods of four weeks each (closed loop or open loop) will be conducted. Within each block, the sequence closed loop-open loop or open loop-close loop is randomized. Outcomes will be analyzed on the third and fourth weeks of period. A remote monitoring system managed by specialized nurse on behalf of diabetologist, is provided in closed-loop session. An extension period of 48 weeks with the DBLHU System (closed-loop condition) will be performed at the end of the crossover study phase in real life conditions (without remote monitoring).
An open-label, three-center, randomized, two-session, 4 days inpatient and 6-week follow-up home study phase, crossover study comparing Diabeloop closed-loop (CL) system and sensor-augmented pump (SAP) therapy. The follow-up home study phase will be done only in French centers for a sub study. During this session, patient wearing the closed-loop system will benefit of a 24h/24, 7 d/7, remote monitoring follow-up by specialized nurses, under supervision of a diabetologist. A visualization of glucose CGM curves, insulin delivery, meal and physical activity announcements will be available online through secured website, and the system will send automated message in case of predetermined situations as persistent too high or too low Blood Glucose (BG). Custom settings will be possible by the nurses during the follow-up period.
The study will be conducted in crossover trial, with two 12-weeks periods separated by a Wash-out period of at least one month. According to randomization ,patients will be provided with either Diabeloop system or the usual system. Patients will be trained for the use of blood glucose meter, of external Insulin Pump and Diabeloop system. In both treatment periods, the same blood glucose meter will be used throughout the duration of the study. In two centers (Centre Hospitalier Sud-Francilien and Grenoble), a pre-study will be performed during four weeks to improve the efficacy of Diabeloop system with data collection, to test the manual settings by health care providers and patients and to check the good-working of the follow-up platform.
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.
