FIasp® vs. Novolog® in Type 1 Diabetics Using 670G Medtronic Pump
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.

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.

Outcome Measures
Primary Outcome Measures
- 1-Hour Change in Postprandial Plasma Glucose (PPG) [6th week of therapy]
Change was calculated as the PPG value at 1 hour minus the PPG value at baseline (time -2 minutes) during meal test
Secondary Outcome Measures
- 2-Hour Change in Postprandial Plasma Glucose (PPG) [6th week of therapy]
Change was calculated as the value at 2 hour minus the value at baseline during meal test
- 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)
- Percentage of Time Spent Between 70 mg/dL and 180 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)
- Percentage of Time Spent Above 200 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)
- Percentage of Time Spent in Hypoglycemia (40 mg/dL - 54 mg/dL) [Weeks 1 through 6, Weeks 8 through 13]

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