Brief summary

Prospective, multi-center, single-arm study in adults and children ages 6 to 80 with type 1 diabetes to evaluate the safety of Lyumjev with Control-IQ technology to achieve labeling updates for Lyumjev and the t:slim X2 insulin pump.

Detailed description

This is a prospective, multi-center, single-arm study in adults and children (ages 6 to 80 years) with type 1 diabetes who are current users of the t:slim X2 insulin pump with Control-IQ technology to achieve labeling updates for Lyumjev and the t:slim X2 insulin pump. After a run-in period, participants will use the study pump with Control-IQ technology 1.5 and Lyumjev insulin for a 3-month outpatient treatment period. Up to 200 participants will be enrolled so at least 160 complete the study.

Interventions

t:slim X2 insulin pump with Control-IQ technology 1.5, and wearing the Dexcom G6 sensor, used with Lyumjev® insulin.
