A Trial Comparing the Efficacy of Insulin Degludec With Insulin Glargine on Glycaemic Control Using Continuous Glucose Monitoring in Patients With Type 1 Diabetes

This trial is conducted in the United States of America (USA). The aim of this trial is to compare the efficacy of insulin decludec with insulin glargine on glycaemic control using continuous glucose monitoring in patients with type 1 diabetes.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Type 1 diabetes
  • HbA1c (glycosylated haemoglobin) below or equal to 8.5%
  • Current treatment with IGlar (insulin glargine) in a basal-bolus regimen with a total daily dose below 120 U
  • BMI (body mass index) below 35 kg/m^2

Exclusion criteria

  • Use within the last 3 months prior to visit 1 (screening) of any antidiabetic glucose lowering drug other than insulin/insulin analogues
  • Subjects with regular use of acetaminophen who are not willing to use another analgetic during CGM (Continuous Glucose Monitoring) periods
  • Stroke; heart failure; myocardial infarction; unstable angina pectoris; coronary arterial bypass graft or angioplasty within 24 weeks prior to visit 1
  • Recurrent severe hypoglycemia (more than one severe hypoglycemic event during the last 12 months) or hypoglycemia unawareness or hospitalization for diabetic ketoacidosis during the previous 6 months

Treatment and study plan

insulin degludec

Drug

Administered subcutaneously (s.c., under the skin) once daily.

insulin glargine

Drug

Administered subcutaneously (s.c., under the skin) once daily.

Primary outcomes

  1. Average Time Within Glycaemic Target Range (Above 70 mg/dL and Below 130 mg/dL)

    Time frame: CGM occured during the last 2 weeks of the 6 weeks treatment period.

    Time within the glycaemic target range [> 70 mg/dL (3.9 mmol/L) and < 130 mg/dL (7.2 mmol/L)] measured by Continuous Glucose Monitoring (CGM) in the last four hours of each dosing interval during the last 2 weeks of the 6-week treatment period.

Secondary outcomes

  1. Mean Interstitial Glucose (IG) Based on 14 Days of CGM

    Time frame: CGM monitoring occurred during the last 2 weeks of the 6-week treatment period.

    The observed mean of IG profile was obtained as the average value of area under the IG profile divided by the actual assessment time interval during the last 2 weeks of the 6-week treatment period.

  2. Fasting Plasma Glucose (FPG)

    Time frame: At the end of each 6 week treatment period.

    FPG after 6 weeks of treatment in each treatment period.

  3. Glycosylated Haemoglobin (HbA1c)

    Time frame: At the end of each 6 week treatment period.

    HbA1c after 6 weeks of treatment in each treatment period.

  4. Number of Treatment Emergent Adverse Events (AEs)

    Time frame: Within each week 6 treatment period

    Number of treatment emergent adverse events (TEAEs). An AE was defined as treatment emergent if the onset date was on or after the first day of exposure to randomised treatment and no later than 7 days after the last day of randomised treatment. Severity was assessed by investigator.

  5. Number of Treatment Emergent Confirmed Hypoglycaemic Episodes

    Time frame: Hypoglycemic episodes reported within each 6 week treatment period.

    A hypoglycaemic episode was defined as treatment emergent if the onset of the episode occurred after the first administration of investigational medicinal product (IMP), and no later than 7 days after the last day on trial product. Confirmed hypoglycaemic episodes consisted of severe hypoglycaemia or minor hypoglycaemic episodes. Severe hypoglycaemic episodes: requiring assistance to administer carbohydrate, glucagon or other resuscitative actions. Minor hypoglycaemic episodes: able to treat her/himself and plasma glucose below 3.1 mmol/L.
