What researchers measure

Primary outcomes

  1. Time above range 180 mg/dl

    The primary outcomes is a difference in CGM-measured metrics between periods (Minimed 670G 4.0 closed loop with Faster Insulin aspart and Minimed 670G 4.0 closed loop with Standard Insulin aspart) in superiority for proportion of time \>180 mg/dL (10.0 mmol/L)

    Time frame: 12 weeks for each arm of the crossover

Secondary outcomes

  1. Time in range 70-180 mg/dl

    CGM derived indices over the study period of each treatment period ((Minimed 670G 4.0 closed loop with Faster Insulin aspart and Minimed 670G 4.0 closed loop with Standard Insulin aspart)) for 24/7 in time in range 70 to 180 mg/dL (3.9 to 10.0 mmol/L

    Time frame: 4 weeks for each arm of the crossover

  2. Time below range <70 mg/dl

    CGM derived indices over the study period of each treatment period ((Minimed 670G 4.0 closed loop with Faster Insulin aspart and Minimed 670G 4.0 closed loop with Standard Insulin aspart)) for 24/7 in time below range 70 mg/dl

    Time frame: 4 weeks for each arm of the crossover

  3. Mean glucose

    CGM derived indices over the study period of each treatment period ((Minimed 670G 4.0 closed loop with Faster Insulin aspart and Minimed 670G 4.0 closed loop with Standard Insulin aspart)) for 24/7 in mean glucose

    Time frame: 4 weeks for each arm of the crossover
