About

This US study will evaluate the safety and effectiveness of utilizing insulin Lyumjev® lispro-aabc in the MiniMed™ 780G System in Type 1 adult and pediatric subjects in a home setting to support product and system labeling.

Full description

This study is a multi-center, single arm study in insulin-requiring adult and pediatric subjects with type 1 diabetes on the MiniMed™ 780G system using Lyumjev® insulin lispro-aabc and Medtronic Extended infusion set and reservoir. The run-in period and study period will be approximately 120 days long. A total of up to 250 subjects with insulin-requiring type 1 diabetes age 7-80 will be enrolled at up to 25 investigational centers across the United States in order to have at least 200 subjects enter the study period. Up to 125 subjects will be enrolled in the pediatric age group (7-17 years of age) and up to 125 in the adult age group (18 years or older).
