About this study
Official title: Assessement of the Influence of Continuous Glucose Measurement on Glucose Control of Type 1 Diabetic Patients Treated by Implanted Insulin Pump
During this study, we propose to assess the utility of Continuous Glucose Measurements (CGM) in a group of Type 1 diabetic patients treated with an implanted insulin pump. Patients will participate in two period of 3 months separated by a 3 months washout. During one period, they will use CGM to adapt their insulin therapy while during the other period, they will manage their diabetes with their usual capillary blood glucose meter. We except to observe an increase of time spent in glucose safe range when using CGM.
Read the detailed description
Glucose control and quality of life of patients with type 1 diabetes with high glucose variability can be improve with use of an implanted pump which delivers insulin by the intra-peritoneal route. Some patients however still have difficulties to achieve their glycemic goal despite this therapy. Continuous Glucose Measurements (CGM) has proven to be able to improve glucose control (HbA1c, time spent in hypoglycaemia) of patients treated with an external insulin pump. No trial has been performed yet to assess the utility of CGM on patients using an intra-peritoneal insulin delivery.
During this study, we propose to assess the influence of CGM use on type 1 diabetic subject treated with implanted insulin pump. It is a prospective, randomized cross-over study. After a 2 weeks run-in period with CGM followed by a 4 weeks break, subjects will participate at two experimental periods of 3 months separated with a 3 month washout. During the intervention phase, patient will use a CGM system (Abbott Freestyle Navigator II) to adapt their insulinotherapy. During the control period, patients will based their insulinotherapy upon their usual care and capillary glucose measurements. The order of the periods will be randomized.
The main endpoint will be the time spent in glucose interval 70-180mg/dL during the last 20 days of each period. The control arm will wear a blinded sensor during this phase to allow comparison.

Where is the study taking place?
The record lists 10 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.
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?
The study was stopped early (reason given: CGM Navigator isn't longer available (October 11, 2019)). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Time spent with glucose (time frame: last 20 days of intervention period). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 9 Dec 2021.
