A 52-Week, Randomised, Double Blind, Active-Controlled, Multi-Centre Phase IIIb/IV Study to Evaluate the Efficacy and Tolerability of Saxagliptin Compared to Glimepiride in Elderly Patients With Type 2 Diabetes Mellitus Who Have Inadequate Glycaemic Control on Metformin Monotherapy

Proportion of Patients Reaching HbA1c <7% After 52 Weeks of Treatment Without Confirmed or Severe Hypoglycaemia.

时间窗: From week 0 to week 52.

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.
