  • Do not oppose to the said research.

Who cannot join

  • Patients with type 2 diabetes,
  • Patients with a cause other than diabetes that could disrupt sleep:
  • Known or suspected sleep apnea syndrome with high risk according to the Berlin questionnaire, And/or
  • Presence of risk factors such as severe retinopathy, nephropathy, hypertension, autonomic neuropathy, chronic psychiatric disorders, endocrine or metabolic pathologies that have not been stabilized, therapeutics that may alter sleep (i.e. sleeping pills, corticosteroids, antidepressants, anxiolytics, antihistamines), regular use of cannabis, abusive use of alcohol (regularly > 3 drinks per day for a man and > 2 drinks for a woman) And/or

About this study

Sleep is crucial for physical and mental health. Environmental, social, or professional pressures can cause sleep duration to fall below the recommended 7-9 hours of sleep per night. Young adults with type 1 diabetes, have additional interference with fear, control and management of hypo/hyperglycemia management, alarms from their devices, which delay bedtime, disrupt sleep and generate multiple awakenings and difficulty returning to sleep. Sleep disturbance is correlated with blood glucose variability as recently demonstrated by a coupled analysis of sleep and glucose level collected by Continuous Glucose Monitoring (CGM). In this study, higher glucose variability predicted impaired sleep at the individual level.

Automated insulin infusion has shown impressive results in clinical and real-life studies, with more than 90% of patients achieving good glycemic control. Il seems to improve sleep quality in subjects after 4 weeks in hybrid closed-loop, self-administered studies compared to a control group.

The main objective of our study is to measure the positive influence of a better glycemic control on the different sleep parameters in subjects with type 1 diabetes at the time of the passage in hybrid closed-loop and in comparison to an identical period in open-loop.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Sleep efficiency

    To evaluate if the optimization of glycemic control after 1 month of use of a hybrid closed loop improves sleep efficiency, i.e. the change of ratio of measured sleep time to time in bed * 100, evaluated by the actiwatch 2 (AW2) actigraph from inclusion (before the switch to the hybrid closed loop) to 1 month after the switch.

    Measured: Change between inclusion and 1 month after the switch to the hybrid closed loop

Questions about this trial

What is this clinical trial studying?

An observational study of Type 1 Diabetes, run by Hospices Civils de Lyon at 1 site 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 7 inclusion and 8 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: finished, as of the sponsor's last update on 7 Aug 2024. 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 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Sleep efficiency (time frame: Change between inclusion and 1 month after the switch to the hybrid closed loop). 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 7 Aug 2024.
