Defined as obtained on or before the 8th day after the last dosing day, as determined by central laboratory. Safety analysis set.

Confirmed hypoglycaemia defined as: any event defined as either a symptomatic event with blood glucose level <3 mmol/L (<54 mg/dL) and no need for external assistance, or an asymptomatic blood glucose measurement <3 mmol/L (<54 mg/dL).

Major (or severe) hypoglycaemia defined as: symptomatic events requiring external assistance due to severe impairment in consciousness or behaviour, with or without blood glucose level <3 mmol/L (<54 mg/dL), but with prompt recovery after glucose or glucagon administration. These events may be associated with sufficient neuroglycopenia to induce seizure or coma. Plasma glucose measurements may not be available during such an event, but neurological recovery, attributable to the restoration of plasma glucose to normal, was considered sufficient evidence that the event was induced by a low plasma glucose concentration.

Measured as the difference between the last on-treatment value (defined as obtained before or on the 8th day after the last dosing date), and the last pre-randomisation HbA1c value, as determined by central laboratory. Full analysis set.

The number of subjects with non-missing baseline and Week 52 (LOCF) values in the full analysis set (defined as the subset of patients in the randomized analysis set who took at least one randomised IP dose and have non-missing baseline and post-baseline efficacy data for at least one variable).

Proportion of patients with their last on-treatment value (defined as obtained before or on the 8th day after the last dosing date), as determined by central laboratory, below the specified limits. Full analysis set.

The number of subjects with non-missing baseline and Week 52 (LOCF) values in the full analysis set (defined as the subset of patients in the randomized analysis set who took at least one randomised IP dose and have non-missing baseline and post-baseline efficacy data for at least one variable).

Measured as the difference between the last on-treatment value (defined as obtained before or on the first day after the last dosing date)and the last pre-randomisation fasting plasma glucose value, as determined by central laboratory. Full analysis set.

The number of subjects with non-missing baseline and Week 52 (LOCF) values in the full analysis set (defined as the subset of patients in the randomized analysis set who took at least one randomised IP dose and have non-missing baseline and post-baseline efficacy data for at least one variable).

Measured as the difference between the last on-treatment value (defined as obtained before or on the first day after the last dosing date) and the last pre-randomisation fasting plasma insulin value, as determined by central laboratory. Full analysis set.

The number of subjects with non-missing baseline and Week 52 (LOCF) values in the full analysis set (defined as the subset of patients in the randomized analysis set who took at least one randomised IP dose and have non-missing baseline and post-baseline efficacy data for at least one variable).

β-cell function as estimated by the homeostasis model assessment (HOMA) model. Value is derived from FPG and fasting insulin; fasting insulin values below 2.074 μU/mL or above 57.595 μU/mL and FPG values below 3 mmol/L or above 25 mmol/L are excluded (as restricted by the calculation method used).
