Number of Treatment Emergent Severe or Blood Glucose (BG) Confirmed Hypoglycaemic Episodes

Treatment emergent hypoglycaemic episode is defined as an event that had onset date on or after the first day of trial product administration, and no later than 7 days after the last day on trial product. Severe or BG confirmed hypoglycaemic episodes were defined as episodes that were severe according to the American Diabetes Association (ADA) classification or BG confirmed by a plasma glucose value \< 3.1 mmol/L (56 mg/dL) with or without symptoms consistent with hypoglycaemia. Severe hypoglycaemia according to the ADA definition: an episode requiring assistance of another person to actively administer carbohydrate, glucagon, or take other corrective actions. Plasma glucose concentrations may not be available during an event, but neurological recovery following the return of plasma glucose to normal is considered sufficient evidence that the event was induced by a low plasma glucose concentration.

Time frame: Weeks 0-52

Change From Baseline in HbA1c (Glycosylated Haemoglobin) Tested for Superiority of IDegLira vs IDeg

Change from baseline (week 0) in HbA1c after 52 weeks of treatment was measured. Statistical analysis was performed to test the hypothesis: superiority of IDegLira vs. IDeg.

Severe hypoglycaemia according to the ADA definition: an episode requiring assistance of another person to actively administer carbohydrate, glucagon, or take other corrective actions. Plasma glucose concentrations may not be available during an event, but neurological recovery following the return of plasma glucose to normal is considered sufficient evidence that the event was induced by a low plasma glucose concentration.

Time frame: 0-52 weeks

Treatment emergent hypoglycaemic episode is defined as an event that had onset date on or after the first day of trial product administration, and no later than 7 days after the last day on trial product.

Time frame: 0-52 weeks

Anti-drug Antibodies: Anti-insulin Degludec Antibodies

Insulin degludec (IDeg)-specific antibodies were measured at week 52, as %B/T (percentage of bound \& precipitated radioactive drug/total added drug to the sample). A sample is measured in 2 different series. In series 1, the radioactive IDeg (tracer) and surplus unlabeled IDeg are added to the sample. In series 2, the tracer and surplus unlabeled human insulin are added to the sample. Series 1 represents unspecific background binding. Series 2 represents IDeg specific antibodies including unspecific background binding. The reported %B/T is calculated by subtracting the background %B/T in series 1 from the %B/T result in series 2. If the background result has higher values than the %B/T in series 2, the resulting value is negative %B/T. Here, a negative %B/T value means that the test samples do not have IDeg-specific antibodies. The reason for getting a negative value for %B/T is due to variation in the analytical background. Thus, the results presented are not a change from baseline.

Time frame: at week 52

Anti-drug Antibodies: Number of Participants Positive or Negative for Anti-liraglutide Antibodies
