Change History
Current Secondary Outcome Measures  ICMJE
 (submitted: September 3, 2012)
  • HbA1c: Change From Baseline to Study Endpoint [ Time Frame: baseline, study endpoint: week 12 or earlier in case of premature discontinuation ]
    Change = study endpoint - baseline
  • Self-Monitored Fasting Plasma Glucose (SMFPG) Mean : Change From Baseline to Study Endpoint [ Time Frame: baseline, study endpoint: week 12 or week 8 if value not available at week 12 ]
    SMFPG mean = mean of the fasting plasma glucose values recorded on the 6 consecutive days before the visit (at least 3 values needed). Change = study endpoint - baseline.
  • 7-point Plasma Glucose Profile: Change From Baseline to Study Endpoint [ Time Frame: baseline, study endpoint: week 12 or week 8 if value not available at week 12 ]
    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 [ Time Frame: baseline, week 4, week 8, week 12 ]
    Daily dose at the face-to-face visits
  • Number of Patients With at Least One Episode of Symptomatic Hypoglycemia [ Time Frame: During the treatment period (12 weeks) plus 7 days after last dose ]
    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]
  • Change in Body Weight From Baseline to Study Endpoint [ Time Frame: baseline, study endpoint: week 12 or week 8 or week 4 depending on last available value ]
    Change = study endpoint - baseline
Original Secondary Outcome Measures  ICMJE
 (submitted: February 25, 2009)
  • HbA1c [ Time Frame: At baseline and week 12 ]
  • Self-monitored Fasting Plasma Glucose (FPG) [ Time Frame: At baseline, weeks 8 and 12. ]
  • Plasma glucose profile (7-point 24h profile) [ Time Frame: At baseline, weeks 8 and 12. ]
  • Hypoglycemia occurrence [ Time Frame: From the baseline to the end of treatment ]

Descriptive Information
Brief Title  ICMJE Evaluation of Insulin Glargine in Combination With Sitagliptin in Type 2 Diabetes Patients: EASIE Extension Trial
Official Title  ICMJE Combination Therapy of Insulin Glargine and Sitagliptin in Patients With Type 2 Diabetes Not Adequately Controlled by a Previous Treatment With Metformin and Either Insulin Glargine or Sitagliptin
Brief Summary

This study was the extension of the LANTU_C_02761 study named EASIE and identified as NCT00751114 (core study comparing insulin glargine versus sitagliptin in insulin-naïve patients treated with metformin and not adequately controlled).

All patients with Glycosylated Hemoglobin A1c (HbA1c) ≥ 7% at the end of the core study had the possibility to enter this extension study if they met the other inclusion criteria and did not present with any exclusion criteria.

The visit 14 of the core study (week 24) was the visit 1 (baseline, week 0) of the extension study which consisted of a 12-week treatment period.

The objectives of this extension study were:

  • To assess the glycemic control (HbA1c <7%) of a 3-month combination therapy with metformin, insulin glargine and sitagliptin in patients not adequately controlled by a previous treatment with metformin plus either insulin glargine or sitagliptin.
  • To assess the effect of insulin glargine in combination with sitagliptin on HbA1c level, fasting plasma glucose, 7-point glucose profile, hypoglycemia occurrence, body weight and overall safety.

Study Design  ICMJE Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE Diabetes Mellitus, Type 2
Intervention  ICMJE
  • Drug: Insulin Glargine
    Subcutaneous injection. 100 Units/mL solution for injection in a prefilled SoloStar® pen (3 mL).
    Other Name: Lantus®
  • Drug: Sitagliptin
    Oral administration. 100mg film-coated tablets.
    Other Name: Januvia®
  • Drug: Metformin
    Patients continued with metformin as usual oral anti-diabetic treatment.
Study Arms  ICMJE Experimental: Combination insulin glargine and sitagliptin

Insulin glargine administered once a day, in the evening, at dinner or at bedtime. Starting dose: - last dose administered in the core study for patients previously treated with insulin glargine, - 0.2 U/Kg of body weight for patients previously treated with sitagliptin. Monitoring of blood glucose and titration: all patients, irrespective of their previous treatment group in the core study were empowered to adjust their insulin doses, under strict investigator's supervision. The goal was to achieve through a force titration 70 < Fasting Plasma Glucose (FPG) ≤ 100 mg/dL (3.9 <FPG ≤ 5.5 mmol/L).

Sitagliptin: stable dose of 100 mg once a day administered with or without food.

  • Drug: Insulin Glargine
  • Drug: Sitagliptin
  • Drug: Metformin
