Outcome Measures

Primary Outcomes (2)

  • The Long-term Safety of the Eversense CGM Systems Over Repeat Insertion and Removal Cycles in the Post-market Setting.

    The primary safety endpoint was the incidence of the composite of infection, secondary procedures to remove the Sensor, or procedure-related adverse events of at least moderate severity, with a performance goal of \< 4%.

    up to 27 months

  • The Long-term Effectiveness of the Eversense CGM Systems Over Repeat Insertion and Removal Cycles in the Post-market Setting.

    The primary effectiveness endpoint was Time in Range, which is defined as glucose values between 70 mg/dL and 180 mg/dL, at 12 months post-first Sensor insertion compared to the first month post-first Sensor insertion.

    Baseline and Month 12

Secondary Outcomes (11)

  • The Additional Effectiveness Endpoint of Average Hours of Use Per Day

    up to 27 months

  • The Additional Effectiveness Endpoint of Change in HbA1c Levels at Each 6-month Interval From Baseline

    Baseline, Month 6, Month 12, Month 18, and Month 24

  • Patient Satisfaction With CGM System Use (CGM-SAT Scale)

    up to 27 months

  • Patient Reported Diabetes Distress Scale (DDS)

    Screening, Day 180, Day 360, and Day 720

  • Success Rate of Insertion Procedures: Overall and by HCP Experience

    up to 27 months

  • +6 more secondary outcomes
