About this study

The purpose of this study evaluate the safety and efficacy of the Advanced Hybrid Closed Loop (AHCL) system in sub-optimally controlled patients with T1D, in comparison with Multiple Daily Injection (MDI) therapy with Flash Glucose Monitoring (FGM) or Continuous Glucose Monitoring (CGM). Patient with a diagnosis of Type 1 diabetes currently under MDI+ FGM or MDI+ CGM therapy will be enrolled.

Read the detailed description

This study is a pre-market, multi-center, prospective, open label, adaptative, randomized controlled trial in insulin-requiring adult subjects with type 1 diabetes on MDI therapy. The study will have three period:

  1. Run-in Phase: The Run-in period is of 4 weeks (and can be extended for 2 additional ones) during which time a blinded CGM sensor will be worn for two weeks.
  2. Study Phase: There will be a 6 months randomized study period with two arms: Treatment Arm (AHCL) and the Control Arm.
  3. Continuation Phase: There will be a 6 months continuation phase during which time all the subjects will use the AHCL system.

Approximately 124 subjects will be enrolled in the study up to 20 investigational centers in EMEA.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • MDIOther

    Subject continues their standard Multiple Daily Injections therapy with FGM or RT-CGM

  • AHCLDevice

    Subject starts using the Advance Hybrid Close Loop (AHCL) MiniMed™ 670G system version 4.0.

    Starting time depends on which Arm the subject is assigned to: if the subject is assigned to the Treatment Arm, then the intervention starts after the RUN-IN period. If the subject is assigned to the Control Arm the intervention will start after 6 months from the date of the enrollment.

Study groupRoleWhat they receive
Control ArmActive comparatorThe Control Arm will use individual subject's current diabetes therapy (MDI+FGM or MDI+CGM) for 6 months during the Study Phase. During the Continuation Phase of 6 months Control Arm will start using the Advance Hybrid Close Loop (AHCL) MiniMed™ 670G system version 4.0
Receives: Other: MDI; Device: AHCL
Treatment ArmExperimentalThe Treatment Arm will use the Advance Hybrid Close Loop (AHCL) MiniMed™ 670G system version 4.0 for 6 months during the Study Phase and other 6 months during the Continuation Phase.
Receives: Device: AHCL

What is being measured

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

  1. HbA1c 6 Months Change Between AHCL and MDI

    The difference in the mean HbA1c change (6 months - baseline) between the AHCL and the MDI + FGM arm will be evaluated (Cohort A).

    Measured: Baseline and end of 6-month study phase

Secondary outcomes (3)
  1. TIR Between 70-180 mg/dL

    % Time spent within range with sensor glucose (SG) between 70 - 180 mg/dL (3.9-10.0 mmol/L). The difference in the mean between the AHCL and the MDI + FGM arm will be evaluated (Cohort A).

    Measured: 6 months study phase

  2. Time in Hyperglycemic Range

    % Time spent in hyperglycemic range with SG > 180 mg/dL (> 10.0 mmol/L). The difference in the mean between the AHCL and the MDI + FGM arm will be evaluated (Cohort A).

    Measured: 6 months study phase

  3. Hypoglycemic Events

    Number of biochemical hypoglycemic events< 54 mg/dL (3.0 mmol/L) (defined as sensor values < 54 mg/dL (3.0 mmol/L) per 15 consecutive minutes (Danne, 2017). When the time between two successive events is less than 30 minutes, they will be combined and counted as one event. The difference in the mean between the AHCL and the MDI + FGM arm will be evaluated (Cohort A)

    Measured: 6 months study phase

What does the primary outcome measure?

HbA1c 6 Months Change Between AHCL and MDI (time frame: Baseline and end of 6-month study phase). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04235504, which also lists 4 linked publications.

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.
