  Purpose

The primary objective was to demonstrate the superiority of insulin glargine over sitagliptin in reducing Glycosylated Hemoglobin A1c (HbA1c) from baseline to the end of the treatment period.

Secondary objective was to assess the effect of insulin glargine in comparison with sitagliptin on:

  • HbA1c level
  • Fasting Plasma Glucose (FPG)
  • 7-point plasma glucose (PG) profiles
  • Percentage of patients with HbA1c <7% and <6.5%

Safety objectives consisted of:

  • Hypoglycemia occurrence
  • Body weight
  • Overall safety

Primary Outcome Measures:
  • HbA1c: Change From Baseline to Study Endpoint [ Time Frame: baseline (week 0), study endpoint: visit 14 (week 24) or visit 11 (week 12) if value not available at visit 14 ] [ Designated as safety issue: No ]
    Change in HbA1c from baseline to study endpoint defined as the last available HbA1c value measured during the 24-week treatment period.


Secondary Outcome Measures:
  • HbA1c Response Rate: Percentage of Patients Who Reach the Target of HbA1c < 7% at Study Endpoint [ Time Frame: study endpoint: visit 14 (week 24) or visit 11 (week 12) if value not available at visit 14 ] [ Designated as safety issue: No ]
  • HbA1c Response Rate: Percentage of Patients Who Reach the Target of HbA1c < 6.5% at Study Endpoint [ Time Frame: study endpoint: visit 14 (week 24) or visit 11 (week 12) if value not available at visit 14 ] [ Designated as safety issue: No ]
  • Self-monitored Fasting Plasma Glucose (SMFPG) Mean : Change From Baseline to Study Endpoint [ Time Frame: baseline (week 0), study endpoint: visit 14 (week 24) or visit 12 (week 16) or visit 11 (week 12) or visit 8 (week 6) depending on last available value ] [ Designated as safety issue: No ]

    SMFPG mean = mean of the fasting plasma glucose values recorded on the 6 consecutive days before the visit (at least 3 values needed).

    Study endpoint was defined as the last available SMFPG mean value collected on-treatment.

    Change= study endpoint - baseline


  • 7-point Plasma Glucose Profile: Change From Baseline to Study Endpoint [ Time Frame: baseline (week 0), study endpoint: visit 14 (week 24) or visit 11 (week 12) if value not available at visit 14 ] [ Designated as safety issue: No ]

    7-point plasma glucose recorded before and after breakfast, before and after lunch, before and after dinner and at bedtime.

    Change = study endpoint - baseline.


  • Insulin Dose in the Insulin Glargine Group [ Time Frame: visit 4 (week 2), visit 8 (week 6), visit 11 (week 12), visit 12 (week 16), visit 14 (week 24), first dose received defined as first available value, study endpoint defined as last available value ] [ Designated as safety issue: No ]
    Daily dose at the face-to-face visits.

  • Lipid Profile: Change From Baseline to Study Endpoint [ Time Frame: baseline (week 0), study endpoint: visit 14 (week 24) or visit 11 (week 12) if value not available at visit 14 ] [ Designated as safety issue: No ]
  • Change in Body Weight From Baseline to Study Endpoint [ Time Frame: baseline (week 0), study endpoint: visit 14 (week 24) or visit 12 (week 16) or visit 11 (week 12) or visit 8 (week 6) depending on last available value ] [ Designated as safety issue: Yes ]
  • Number of Patients With at Least One Episode of Symptomatic Hypoglycemia [ Time Frame: During the treatment phase (24 weeks) plus 7 days after last dose ] [ Designated as safety issue: Yes ]
    Symptomatic hypoglycemia was defined as an event with clinical symptoms that were considered to result from hypoglycemia confirmed or not by a plasma glucose measurement <= 70mg/dL [3.9 mmol/L]

  • Number of Patients With at Least One Episode of Severe Symptomatic Hypoglycemia [ Time Frame: During the treatment phase (24 weeks) plus 7 days after last dose ] [ Designated as safety issue: Yes ]
    Severe symptomatic hypoglycemia was defined as an event with clinical symptoms which required assistance of another person and with either a Plasma Glucose level < 36 mg/dL (2 mmol/L) or with a prompt recovery after oral carbohydrate, intravenous glucose, or glucagon administration
