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

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.

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.

Eligibility Criteria:
Inclusion Criteria:

2. Male or female, age ≥18 years at the time of signing informed consent
3. Documented diagnoses of T1DM ≥1 year prior to the day of screening
4. Using the Medtronic pump Minimed 670G for CSII in a basal-bolus regimen with a rapid acting insulin analogue for at least 30 days prior to screening and willing to continue using their personal Medtronic Minimed 670G and CSII for insulin treatment throughout the trial.
5. Ability and willingness to use the same insulin infusion sets throughout the trial
6. Using the same insulin for at least 30 days prior to screening
7. HbA1c \< 8.5% as assessed by local laboratory at screening
8. BMI ≤ 35.0 kg/m2 at screening
9. Ability and willingness to adhere to the protocol including performing SMPG profiles, attending visits, utilizing the auto mode feature of the pump for at least 80 % of the time during the study, and completing meal tests

Exclusion Criteria:

1. Known or suspected hypersensitivity to trial products or related products
2. Female who is pregnant, breast-feeding or intends to become pregnant or is of child-bearing potential and not using adequate contraceptive methods (adequate contraceptive measures as required by local regulation or practice)
3. Participation in another clinical trial within 28 days before the screening visit. Note: clinical trials do not include non-interventional studies
4. Anticipated significant change in lifestyle (e.g. eating, exercise or sleeping pattern) throughout the trial
5. Any of the following: myocardial infarction, stroke, hospitalization for unstable angina or transient ischemic attack within the past 180 days prior to the day of screening
6. Subjects classified as being in New York Heart Association (NYHA) Class IV at screening
7. Planned coronary, carotid or peripheral artery revascularization known on the day of screening.
8. Inadequately treated blood pressure defined as Grade 3 hypertension or higher (Systolic

   ≥180 mmHg or diastolic ≥110 mmHg) at screening
9. Impaired liver function, defined as ALT ≥ 2.5 times upper normal limit at screening
10. Renal impairment measured as estimated Glomerular Filtration Rate (eGFR) value of \< 45 ml/min/1.73 m2
11. Anticipated initiation or change in concomitant medications (for more than 14 consecutive days) known to affect weight or glucose metabolism in the opinion of the Investigator
12. Proliferative retinopathy or maculopathy requiring acute treatment at the time of screening
13. History of hospitalization for ketoacidosis ≤180 days prior to the day of screening
14. Treatment with any medication for the indication of diabetes or obesity other than stated in the inclusion criteria within 30 days before screening
15. Presence of malignant neoplasms at the time of screening. Basal and squamous cell skin cancer and any carcinoma in-situ is allowed.
16. Reoccurring Severe hypoglycemia while on the Medtronic Minimed 670G in the investigators opinion
17. Any condition which, in the opinion of the Investigator, might jeopardize Subject's safety or compliance with the protocol
