A study testing Guardian Connect, Medtronic and Abbott Diabetes Care in people with Type 1 Diabetes, run by Queen Fabiola Children's University Hospital at 1 site in Belgium.
Trial summary
Impaired hypoglycemia awareness, a significant problem for children with type 1 diabetes, is defined as neurogenic symptom response before autonomic response to hypoglycemia. Avoiding hypoglycemia appears to restore hypoglycemia awareness. Read more about this study

About this study
Official title: Prospective Randomized Clinical Study Assessing the Clinical Impact of Continuous vs Flash Glucose Monitoring During a 8 Weeks Period in Children, Adolescents and Young Adults 4 to 20 Years Old With Type 1 Diabetes Previously Using Flash Glucose Monitoring
Impaired hypoglycemia awareness, a significant problem for children with type 1 diabetes, is defined as neurogenic symptom response before autonomic response to hypoglycemia. Avoiding hypoglycemia appears to restore hypoglycemia awareness.
Investigators have previously demonstrated in a retrospective study that Flash Glucose Monitoring system decreased the risk of severe hypoglycemia in type 1 diabetic children and adolescents, even though Flash Glucose Monitoring system, unlike Continuous Glucose Monitoring system, does not provide glucose alerts.
Read more
Continuous Glucose Monitoring system, by providing real-time data with alarms, could benefit to subjects still experiencing severe hypoglycemia with Flash Glucose Monitoring system. Besides, in adults, Continuous Glucose Monitoring system reduced more effectively impaired hypoglycemia awareness compared to Flash Glucose Monitoring system.
In that context, investigators would like to assess the impact of Continuous Glucose Monitoring system instead of Flash Glucose Monitoring system on hypoglycemia in children and adolescents with type 1 diabetes.
Read the detailed description
All subjects will start with a 7 days run-in phase using their current Flash Glucose Monitoring System associated with a blind Continuous Glucose Monitoring system (Envision, Medtronic).
After one week, subjects randomized in the the interventional group will be provided with the Continuous Glucose Monitoring (Guardian Connect, Medtronic) and trained by dedicated diabetes educators for Continuous Glucose Monitoring usage including insertion of the sensor, calibration of the device twice daily and interpretation of the data. Subjects will use the sensors according to the license.
For both groups, insulin doses decisions are made by the participant according the received education.
After one week, all subjects will be contacted by phone focusing on the use of the technology. The treatment period is 8 weeks. The last week of the treatment period, subjects will use the blind Continuous Glucose Monitoring system (Envision, Medtronic) in addition to their allocated Glucose Monitoring system.

Questions about this trial
What is this clinical trial studying?
A study testing Guardian Connect, Medtronic and Abbott Diabetes Care in people with Type 1 Diabetes, run by Queen Fabiola Children's University Hospital at 1 site in Belgium.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 31 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Belgium. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Anissa Messaaoui, MD (+32.2.477.33.84, anissa.messaaoui@huderf.be), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
To evaluate the change in baseline hypoglycemia after 8-week Continuous Glucose Monitoring system use (time frame: At Baseline and after 8 weeks of Continuous Glucose Monitoring system use). 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 NCT04249102, which also lists 1 linked publication.
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 31 Mar 2020.
