Change in time spent in euglycaemia [ Time Frame: Day 1-15 compared with Day 60-74 ] [ Designated as safety issue: No ]
Masked continuous glucose monitoring data will be collected for two weeks at the start of the study and 2 weeks at the end of the study. Analysis will assess the difference between the assessment and baseline phase for the intervention group.
Same as current

  • Change in time spent in euglycaemia [ Time Frame: Day 1-15 compared with Day 60-74 ] [ Designated as safety issue: No ]
    Masked continuous glucose monitoring data will be collected for two weeks at the start of the study and 2 weeks at the end of the study. Analysis will compare the control and intervention groups using analysis of covariance to allow for differences at baseline.
  • Change in HbA1c [ Time Frame: Day 1 compared with Day 74 ] [ Designated as safety issue: No ]
    HbA1c will be tested at baseline (day 1) and then again at end of study (approximately day 74). Analysis will assess the difference between the assessment and baseline results for the intervention group and compare the control and intervention groups.
  • Change in Total Daily Dose (TDD) of insulin [ Time Frame: 5-day diary data collected between Days 1-6 compared with 5-day diary data collected between Days 60-74. ] [ Designated as safety issue: No ]
    5-Day diary data collected during the first 2 weeks of the study will be compared to data collected during the last 2 weeks of the study. Analysis will assess the difference between the assessment and baseline TDD for the intervention group and compare the control and intervention groups.
  • Change in Patient Reported Outcome Measures [ Time Frame: Day 1 compared to Day 60 ] [ Designated as safety issue: No ]
    Diabetes Treatment Satisfaction Questionnaire (DTSQ), Hypoglycaemia Fear Survey (HFS)and Diabetes Distress Scale(DDS)Questionnaires will be completed at Baseline (Day 1) and visit 6 (approximately day 60)and the scores compared. Analysis will assess the difference between the assessment and baseline scores for the intervention group and compare the control and intervention groups.
