About this study
Official title: Impact of the Use of a Closed-loop Insulin Therapy on the Burden of the Diabetes and the Quality of Life in Type 1 Diabetic Patients With Continuous Glucose Monitoring (CGM)
The use by diabetes patients of real-time Continuous Glucose Monitoring (CGM) system is becoming widespread and has changed diabetic practice. Automated closed-loop (CL) insulin therapy has come of age. This major technological advance is expected to significantly improve the quality of care for adults, adolescents and children with type 1 diabetes.
Questions remain about patients' perception and acceptance on this automatisation of the management of their glycemic variability.
Thus this study is built to evaluate the impact of the activation of the closed-loop on quality of life and burden of their diabetes in patients with type 1 diabetes under CSII.
Read the detailed description
This cohort study will follow patients with type 1 diabetes undergoing under continuous subcutaneous insulin infusion (CSII) with Continuous Glucose Monitoring (GCM). After inclusion visit, there's a 20 days' period to assess their quality of life and perception of the burden of their diabetes and confirm their eligibility to the closer-loop. During this 20 days' period, patients should complete all the self-questionnaires.
Then, during the 2d visit, the closed-loop will be activated by the diabetologist for a 6 months follow-up including six visits with 3 phone contacts (at week 1, week 2 and week 6) then 2 direct visits at 3 months and 6 months.
The 3 phone contacts are mainly planned, as recommended in French guidelines, to ensure the good use of the device and to detect or prevent any unexpected events.
The 2 visits at 3 and 6 months, are planned to assess the glycemic variability using Continuous Glucose Monitoring data and to collect perception of the patients via the 2 main criteria self questionnaires (Quality of life and burden to be filled-in by patients at 3 and 6 months) and all perception dimensions by all the self questionnaires.
Main results will provide data on the evolution of quality of life and burden of diabetes by comparison between scores at 6 months and baseline, and evolution of glycemic variability.

What participants receive

Activation of a closed loop device in an insulin pump device with GCMDevice
After a run-in period of 20 days to co,firm eligibility, the closed loop is activated and patients are followed for 6 months by their diabetologists.
| Study group | Role | What they receive |
|---|---|---|
| Type 1 diabetic patients under CSII eligible for closed loop use | Other | Diabetic patients age 13 or above under CSII with continuous glucose monitoring matching eligibility criteria for the use of a closed loop during a 6 months period. During the study, 4 physical appointments with a diabetologist and 3 phone contacts are anticipated. Receives: Device: Activation of a closed loop device in an insulin pump device with GCM |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Quality of life following activation of closed loop
Validated self questionnaire : Audit of Diabetes dependant quality of life (ADQQoL) with 19 items Lower scores reflect worsening quality of life
Measured: Score comparison between Baseline and 6 months after activation of closed loop
Change in burden of diabetes following activation of closed loop
Validated self questionnaire : Problem Areas s in Diabetes (PAID) with 20 items. Higher scores reflect greater emotional distress.
Measured: Score comparison between Baseline and 6 months after activation of closed loop
Secondary outcomes (2)
Perception of patients
Different validated self questionnaires on well-being, Fatigue, Anxiety and Depression, Physical activity, Sleep, Fear of hypoglycemia and personality.
Measured: Before and 6 months after activation of closed loop
Glycemic variability
Collection of symptomatic hypoglycemic and hyperglycemic events. Data from GCM including time in range, time above range, time below range and glycemic variability coefficient.
Measured: Before, 3 months and 6 months after activation of closed loop

The record says: status not confirmed, as of the sponsor's last update on 25 Jun 2021. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Emmanuelle MORRY (0149694515, emmanuelle.morry@vitalaire.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Quality of life following activation of closed loop (time frame: Score comparison between Baseline and 6 months after activation of closed loop). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04939766, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Jun 2021; AzTrials last refreshed its copy on 7 Nov 2026.
