Study Details

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.

Condition or Disease Intervention/Treatment Phase
Phase 3

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.

    2. Percentage of Time Spent Between Below 70 mg/dL [Weeks 1 through 6, Weeks 8 through 13]

      Percent of time spent is calculated as the accumulated time in hours spent within each range divided by the total number of hours spent under therapy with each drug (6 weeks each)

    3. Percentage of Time Spent Between 70 mg/dL and 180 mg/dL [Weeks 1 through 6, Weeks 8 through 13]

    5. Percentage of Time Spent in Hypoglycemia (40 mg/dL - 54 mg/dL) [Weeks 1 through 6, Weeks 8 through 13]

      Percent of time spent is calculated as the accumulated time in hours spent within each range divided by the total number of hours spent under therapy with each drug (6 weeks each)

    6. Percentage of Time Spent in Severe Hypoglycemia (> 40 mg/dL) [Weeks 1 through 6, Weeks 8 through 13]

      Percent of time spent is calculated as the accumulated time in hours spent within each range divided by the total number of hours spent under therapy with each drug (6 weeks each)

    7. 1,5 Anhydroglucitol Levels [Week 6, Week 13]

      1,5 anhydroglucitol levels were measured on the 6th week of each therapy

    8. Fructosamine Levels [Week 6, Week 13]
