Type 1 Diabetes Mellitus in Prepubertal Children Clinical Trial
— FREELIFE-KIDOfficial title:

The study is a randomized trial preceded by a run-in period and followed by a non-randomized study extension. After 3 weeks of outpatient use of study pump (1 week) and study pump+CGM (2weeks) as run-in period, patient and parents will be admitted for 4-hour training to closed-loop (AP) mode. Following randomization (1:1), patient will be allocated to '24-hour' use of AP or 'dinner and overnight AP mode/day time pump and CGM use' for the next 18-week period. At 18-week visit, a study extension for a further 18-week period will be initiated. AP mode that will be prescribed to all patients will depend from an independent DSMB decision based upon study safety data collected after 6 and 12 weeks from the first 30 included patients. Visits will occur at week 27 (safety follow-up) and 36 (final visit).

|---|---|---|---|---|
| Primary | Percent of time spent in the 70-180 mg/dl glucose range assessed on daily CGM data | % time blood glucose in 70-180 mg/dl range | 18 weeks | |
| Secondary | Percent of time spent with glucose level < 70, 60 and 50 mg/dl, assessed on daily CGM data | Percent time while blood glucose is kept in safe 70-180 mg/dl range | 18 and 36 weeks | |
| Secondary | Percent of time spent with glucose level > 180 and 300 mg/dl, assessed on daily CGM data | Percent time while blood glucose is kept in safe 70-180 mg/dl range | 18 and 36 weeks | |
| Secondary | Percent of time spent in the 70-140 mg/dl glucose range assessed on daily CGM data | Percent time while blood glucose is kept in safe 70-180 mg/dl range | 18 and 36 weeks | |
| Secondary | Mean glucose level assessed on daily CGM data | CGM data will be used to calculate daily glucose mean to assess the efficacy of the algorithm on glucose control. | 18 and 36 weeks | |
| Secondary | HbA1c level measured at week 12, 18, 27 and 36 | Levels of glycated hemoglobin will be measured at different time intervals to assess the clinical impact of the use of the algorithm on patient diabetes. | 12,18, 27 and 36 weeks | |
| Secondary | Number of needed interventions by the patients or care providers to treat hypoglycemia | A logbook will be used all along the study by patients to record carbs intake in case of hypoglycemia. If patient required further assistance, care provider who will record third parties intervention. | 18 and 36 weeks | |
| Secondary | Percent of time with AP functional, discriminating between each component failure modes | Percent time while blood glucose is kept in safe 70-180 mg/dl range | 18 and 36 weeks | |
| Secondary | Score of the Artificial Pancreas Acceptance Questionnaire | This questionnaire consists of 15 affirmations about the use of AP and patient can answer in a scale from 0 (do not agree) to 6 (totally agree). The global score is calculated by the sum of all answers. A high score means a good acceptation of the system. There is no subscale. | 18 and 36 weeks |
