NCT04616391

Brief Summary

The primary objective of this study is to evaluate whether the MiniMed 780G AHCL system improves glycemic control and Quality of Life (QoL) perception in adult individuals with T1D and naïve to CSII and CGM technologies. The trial is a two-centers, randomized controlled, parallel group study. Patients will be followed up during approximatively 3 months.

Outcome Measures

Primary Outcomes (1)

  • Between group TIR difference

    Between group difference in the percentage of time spent within range with sensor glucose (SG) between 70-180 mg/dL (TIR) (3.9-10.0 mmol/L).

    Day 78-90

Secondary Outcomes (6)

  • Between group TIR difference >70%

    Day 78-90

  • Between group difference in the percentage of time spent:

    Day 78-90

  • Between group difference in the mean glucose level

    Day 78-90

  • Between group difference in the glycemic variability measure by SD and CV

    Day 78-90

  • Between group difference in the HbA1c levels

    Day 78-90

  • +1 more secondary outcomes

Other Outcomes (3)

  • Number of severe hypoglycemic episodes

    Day 90

  • Number of Diabetic Ketoacidosis events

    Day 90

  • Number of Severe Hyperglycemia episodes

    Day 90

Study Arms (2)

MDI group:

NO INTERVENTION

The patient continues MDI treatment as per routine procedures

AHCL group

EXPERIMENTAL

The patient will use MiniMed 780G AHCL system

Device: insulin pump Medtronic 780G

Interventions

Patients from the AHCL group will use the MiniMed 780G AHCL system. This system is already CE-marked. The AHCL system will be initiated first in Manual Mode (i.e. without AHCL control) with suspend before low feature (Visit 1). The AHCL system will be initiated in Auto Mode (i.e. with AHCL control) at Visit 2 with the settings in the below table. The Insulin to Carb ratio (ICR) and the Active Insulin Time (AIT) may be adjusted by the physician during the study. The glucose target may not be adjusted, unless in case of safety concerns. The patients may not adjust system settings without consulting with the physician. At each visit, the AHCL system data will be downloaded and reviewed by the physician. The patient interaction with the system will be evaluated, included sensor calibration, bolus management (before the meals and for corrections as needed), alarms and Auto Mode exits.
