Primary Outcome Measures:
  • Change in HbA1c (Glycosylated Haemoglobin A1c) [ Time Frame: week 0, week 16 ] [ Designated as safety issue: No ]
    Change in Glycosylated Haemoglobin A1c (HbA1c) from baseline (week 0) to 16 weeks (end of treatment)


Secondary Outcome Measures:
  • Change in 8-point Plasma Glucose Profile [ Time Frame: week 0, week 16 ] [ Designated as safety issue: No ]
    Summary of change in 8-point plasma glucose profile by week and time. The 8 time points measured were: Before each meal (breakfast, lunch and dinner), at 2 hours after each meal (breakfast, lunch and dinner), at bedtime, and at 3 AM, measured over 16 weeks of treatment

  • Percentage of Subjects Achieving HbA1c Less Than 7.0% [ Time Frame: week 16 ] [ Designated as safety issue: No ]
    Percentage of subjects achieving the treatment target of a glycosylated haemoglobin A1c (HbA1c) level below 7.0% after 16 weeks of treatment

  • Percentage of Subjects Achieving HbA1c Below or Equal to 6.5% [ Time Frame: week 16 ] [ Designated as safety issue: No ]
    Percentage of subjects achieving the treatment target of a glycosylated haemoglobin A1c (HbA1c) level below or equal to 6.5% after 16 weeks of treatment

  • Hypoglycaemic Episodes [ Time Frame: weeks 0-16 ] [ Designated as safety issue: Yes ]
    Total number of hypoglycaemic episodes experienced in the trial from week 0 (baseline) to week 16 (end of treatment). Hypoglycaemic episodes were defined as major, minor, or symptoms only. Major if the subject was unable to treat her/himself. Minor if subject was able to treat her/himself and plasma glucose was below 3.1 mmol/L or 56 mg/dL. Symptoms only if subject was able to treat her/himself and with either no plasma glucose or blood glucose measurement or plasma glucose higher than or equal to 3.1 mmol/L or 56 mg/dL.

  • Hypoglycaemic Episodes, Diurnal/Nocturnal [ Time Frame: weeks 0-16 ] [ Designated as safety issue: Yes ]
    Total number of hypoglycaemic episodes experienced in the trial from week 0 (baseline) to week 16 (end of treatment) during the day (diurnal) and the night (nocturnal).
