About this study

Official title: Evolution in Glycemic Control and Quality of Life in Patients With Type 1 Diabetes Using the myLoop System With FreeStyle Libre 3 / 3 Plus Sensors in a Real-World Setting in France

The goal of this observational study is to learn how glucose control changes over one year in people with type 1 diabetes who use the myLoop with CamAPS FX and Freestyle Libre 3 or FreeStyle Libre 3 Plus during usual care in France. The main question it aims to answer is:

  • How time in range (TIR) changes after one year of use. Time in range is the percentage of time glucose levels stay within the target range.
Read more

As secondary aims, the study aims to answer how other glucose measures (other than TIR, for example Time Above / Below Range) change at six months and one year.

Participants who are prescribed the myLoop with CamAPS FX during usual care for Type 1 Diabetes will:

  • agree to have their routine clinical data on diabetes management and related complications before and after starting therapy with myLoop with CamAPS FX used for this study.
  • answer online survey questions about their quality of life, use of the device and features and treatment satisfaction at six months and one year.

Questions about this trial

What is this clinical trial studying?

An observational study of Diabetes Type 1, run by mylife Diabetes Care AG.

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 14 inclusion and 5 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: opening soon, as of the sponsor's last update on 1 Oct 2026. 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?

This study is still under way. Results are not available in the source record yet.

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?

Change from Baseline in the percentage of time in the 70 - 180 mg/dL range (TIR) at 12 Months (time frame: Baseline and 12 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 1 Oct 2026.
