- Registration Number
- NCT04853030
- Lead Sponsor
- University of Ljubljana, Faculty of Medicine
- Brief Summary
A double-blind, multinational, multicenter, randomised, 2-period crossover study to assess the efficacy and safety of advanced closed-loop insulin delivery with Minimed 670G 4.0 system comparing Faster Insulin Aspart to Standard Insulin Aspart therapy over 4 weeks in active children and adolescents with type 1 diabetes.

Group Intervention Description Minimed 670G 4.0 closed loop with Faster Insulin aspart Fiasp - Minimed 670G 4.0 closed loop with Standard Insulin aspart Novorapid -
- Primary Outcome Measures
Name Time Method Time above range 180 mg/dl 12 weeks for each arm of the crossover 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)
- Secondary Outcome Measures
Name Time Method Time in range 70-180 mg/dl 4 weeks for each arm of the crossover 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 below range <70 mg/dl 4 weeks for each arm of the crossover 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
Mean glucose 4 weeks for each arm of the crossover 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
