5. Study Description

Brief Summary
This is an exploratory, single-center, randomized, open label, active-controlled, complete cross-over trial comparing safety and efficacy of Fiasp® versus NovoLog® when used in the Medtronic MiniMed 670G system in subjects with T1DM.
Detailed Description
This study is being performed to compare Fiasp® in terms of glycemic control with a focus on post-prandial 1-hour plasma glucose level and system-based outcomes to NovoLog® insulin when used in the Medtronic mini Med 670G HCL system (operating in auto-mode) in patients with type 1 diabetes. The investigator's hypothesis is that post prandial glucoses will be lower and time in range will be greater during the Fiasp® treatment period. Subjects will have a 2 week screening period, 14 week treatment period and 30 Day follow up period. After at least 7 weeks on treatment period one they will crossover to treatment period two on the opposite treatment for 7 additional weeks.
