Participant Flow

All subjects participated for a minimum of 90 days (Phase 1) and some subjects 18 years of age or older participated for up to 9 months (Phase 2). All subjects wore the Guardian Connect system (real-time CGM) continuously and used smart insulin pens or insulin pens with smart caps for multiple daily injections and continued their standard therapy throughout the duration of the study.

Guardian™ Connect System, InPen™ Basal Smart Cap, and Smart Insulin Pens
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. Guardian™ Connect system, InPen™ Basal smart cap, smart insulin pens, and InPen™ Diabetes Management app: 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.
