Outcome Measures

Primary Outcomes (3)

  • Percentage of Time in Hypoglycemia

    The overall mean percentage of time in hypoglycemia (SG \< 70 mg/dL)

    Day 1 to Day 90 in Phase 1 and Day 91 to up to 9 months in Phase 2

  • Percentage of Time in Euglycemia

    The overall mean percentage of time in euglycemia (SG 70-180 mg/dL)

    Day 1 to Day 90 in Phase 1 and Day 91 to up to 9 months in Phase 2

  • Percentage of Time in Hyperglycemia

    The overall mean percentage of time in hyperglycemia (SG \> 180 mg/dL)

    Day 1 to Day 90 in Phase 1 and Day 91 to up to 9 months in Phase 2

Study Arms (1)

Guardian™ Connect system, InPen™ Basal smart cap, and smart insulin pens

EXPERIMENTAL

All subjects will wear the Guardian Connect system (real-time continuous glucose monitoring (CGM)) continuously and use smart insulin pens or insulin pens with smart caps for multiple daily injections and continue their standard therapy throughout the duration of the study.

Device: Guardian™ Connect system, InPen™ Basal smart cap, smart insulin pens, and InPen™ Diabetes Management app

Interventions

Guardian™ Connect system consists of Guardian™ Connect app, Guardian™ Connect transmitter, and Guardian Sensor (3), will be working with InPen™ Basal smart cap and smart insulin pens and InPen™ Diabetes Management app for multiple daily injections. The subject's insulin delivery, sleep, physical activity (as applicable), food intake data, and medication (as applicable) will be collected through applications with meal logging and medication requiring manual entry. In addition, subjects may also participate in optional self-administered insulin injection video capture and upload using a secure cloud-based site and/or monthly menstrual cycle logging using Apple Health and/or cardiac monitoring using BodyGuardian MINI.
