About this study

Official title: Evaluation of Security and Efficacy of Medtrum Hybrid Closed Loop System in Children, Adolescents and Adults With Type 1 Diabetes

The purpose of this study is to evaluate the safety and effectiveness of the MEDTRUM Hybrid Closed Loop (HCL) System in children, adolescents, and adults with type 1 diabetes (7-75 years old) in a home setting and to test the function of meal announcement in an extend study.

The main question it aims to answer is :

Read more
  • Is the Hybrid Closed Loop system superior at increasing the time spent in the target glucose range of 70-180 mg/dL when compared to the Open (manual) Loop system ?

Participants will be :

  • Trained into the use of the Insulin pump MEDTRUM A8 TouchCare® Insulin Management system
  • Randomized to the Open Loop or Closed Loop group
  • Respond to self administered questionnaires : the Hypoglycaemia Fear Survey, the Diabetes Quality of Life Questionnaire, and the Diabetes treatment Satisfaction Questionnaire status

Researchers will compare the time spent in the target glucose range of 70-180 mg/mL during the last 12 weeks of the study between the patients randomised to the Open Loop group and those randomised to the Closed Loop group.

Conditions
Type 1 Diabetes
Being tested

Study groups in NCT06363916
Study groupRoleWhat they receive
Open LoopPatients using the Insulin Management System device in a manual mode of operation. Patient must use the interface directly to deliver insulin. The algorithm will not be activated.
Receives: Device: Insulin Management System in Manual mode of operation
Closed LoopPatients using the Insulin Management System device in the Closed Loop mode of operation. The algorithm will be activated. The algorithm is capable of delivery of insulin based on sensor derived glucose levels, glucose level trends and insulin pump delivery history. Patients in this group can continue to an exploratory phase for the Automatic Meal Management function.
Receives: Device: Insulin Management System in Automatic mode of operation

Questions about this trial

What is this clinical trial studying?

An observational study of Type 1 Diabetes, run by Medtrum France at 17 sites in France.

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 11 inclusion and 10 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 18 Jun 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 17 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Mélanie MARMOUNIER (0620591224, melanie.marmounier@medtrum.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Superiority of the algorithm on Time In Range (TIR) between the 2 randomised groups (time frame: V5 (6 months)). 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 18 Jun 2024.
