Study summary

The aim of the study is to assess whether the implementation of faster insulin aspart in children with Type 1 diabetes treated with intensive insulin therapy with the use of an insulin pump and using Real Time Continuous Glucose Monitoring (RT-CGM) systems leads to prolonged time in range (TIR) compared to insulin aspart.

Study arms

  • Active comparator
    Insulin Aspart

    Patients will use the continuous subcutaneous insulin infusion of insulin aspart (Novo Rapid, Novo Nordisk) and RT-CGM for 4 weeks.

    Drug: Insulin faster aspart (Fiasp, Novo Nordisk)

  • Experimental
    Insulin Fiasp

    Patients will use the continuous subcutaneous insulin infusion of insulin faster aspart (Fiasp, Novo Nordisk) and RT-CGM for 4 weeks.

    Drug: Insulin faster aspart (Fiasp, Novo Nordisk)

Interventions

  • DrugInsulin faster aspart (Fiasp, Novo Nordisk)

    Duration of the study: 10 weeks. It is assumed that the patients will attend 4 visits in Pediatric Diabetology Clinic, and 3 telephone consultations. W0: The study will start with a 2-week run-in period in order to normalize glycemia. W1: RT-CGM will be inserted. Subsequently, the participants will be randomly assigned to one of two groups (Fa-A or A-Fa), basing on which the order of insulin use will be determined. W2: after 2 weeks, diabetology telephone consultation (washout period). W3: after 2 weeks, diabetology consultation. Changing insulin type according to the allocation. W4: after 2 weeks, diabetology telephone consultation (washout period). W5: after 2 weeks, diabetology telephone consultation. W6: the results obtained throughout the study will be discussed with the patient and the parent.
