Can an artificial pancreas help the Hardest-to-Control diabetes?
NCT ID NCT05282264
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study looked at whether people with severe, long-term uncontrolled type 1 diabetes would accept and benefit from a closed-loop insulin delivery system (an 'artificial pancreas'). Researchers followed 66 adults with very high blood sugar levels over several years. The goal was to see how many kept using the system and whether it improved their blood sugar control.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- closed-loop insulin delivery system
- What this could lead to
- If successful, this could show that closed-loop insulin systems are acceptable and helpful for people with very poorly controlled type 1 diabetes.
- What could go wrong
- This is a small, single-center observational study, not a randomized trial. Results may not apply to all patients, and the system may not work as well in real-world settings.

Inclusion Criteria: Patients with closed loop system : * Adult patients * With T1D for at least 2 years * Follow-up in the diabetes department of the CHSF * Having a laboratory HbA1c \> 11% at least once during the past year and at least one other HbA1c \> 10% in the previous 3 years * Accepting the closed loop system as part of their support * Subject informed of the study and not objecting to it Patients without closed loop system : Adult patients * With T1D for at least 2 years * Follow-up in the diabetes department of the CHSF * Having a laboratory HbA1c \> 11% at least once during the past year and at least one other HbA1c \> 10% in the previous 3 years * Refusing the closed loop system as part of their support or * Patients for whom a multi-professional medical and paramedical collegial discussion (including diabetologist and nurse referents of the patient) within the service leads to the evaluation of an unfavorable benefit/risk ratio * Subject informed of the study and not objecting to it Exclusion Criteria: Patients with closed loop system : * Patients without an Internet connection, or without a smartphone or computer * Patients for whom a multi-professional medical and paramedical collegial discussion (including diabetologist and patient referent nurse) within the department results in the assessment of an unfavorable benefit/risk ratio (patients with a history of interrupted pump treatment on medical decision, serious psychiatric disorders…)
