Effect of Insulin Glulisine Compared to Insulin Aspart and Insulin Lispro When Administered by Continuous Subcutaneous Insulin Infusion (CSII) on Specific Pump Parameters in Patient With Type 1 Diabetes Mellitus
Effect of Insulin Glulisine Compared to Insulin Aspart and Insulin Lispro When Administered by Continuous Subcutaneous Insulin Infusion (CSII) on Specific Pump Parameters in Patient With Type 1 Diabetes Mellitus
Primary objective: To demonstrate the superiority of insulin glulisine over insulin aspart
 and insulin lispro administered by external pump in term of unexplained hyperglycemia and/or
 infusion set occlusion.

 Main Secondary objectives:

 To compare insulin glulisine, insulin aspart and insulin lispro on:

 -  Unexplained hyperglycemia

 -  Infusion set occlusion

 -  Hypoglycemic episodes,7-point blood glucose profiles

 -  Episodes of significant ketosis and/or risk level for impending diabetic ketoacidosis

 -  Time to change the infusion set

 -  HbA1c (Glycosylated hemoglobin)

 -  Overall safety: incidence of adverse events
The maximal duration of the study participation for patients was 41 weeks and one day, split
 in:

 -  a 2-week screening period,

 -  a 39-week treatment period: 3 treatment periods of 13 weeks with a crossover alternative
 regimen, including a dose adjustment period of 1 week at the beginning of each period
 (sequence1: insulin glulisine, then insulin aspart, then insulin lispro; sequence2:
 insulin aspart, then insulin lispro, then insulin glulisine; sequence 3: insulin lispro,
 then insulin glulisine, then insulin aspart)

 -  and a follow-up period of 24 hours.
Inclusion Criteria:

 -  Type 1 diabetic subjects

 -  Treated with insulin for at least 2 years and by CSII for at least 6 months

 -  Using the same insulin (insulin glulisine, insulin aspart or insulin lispro) in CSII
 for at least 3 months with the same external pump compatible with the 3 short acting
 insulin analogues used in the study

 -  Using the same type of infusion set (catheter and cannula) for at least 3 months

 -  Performing at least 3 blood glucose controls per day

 -  HbA1c < 8.5%

 -  Body mass index (BMI) < 35 kg/m²

 -  Ability and willingness to perform blood glucose and ketone monitoring using the
 Sponsor-provided combined glucose and ketone meter and patient diary at home

 Exclusion Criteria:

 -  Diabetes other than Type 1

 -  Total daily dose of insulin greater than 90 U/day

 -  Using an insulin pump requiring pre-filled cartridges

 -  History of infection at infusion site requiring a drainage in the last 3 months

 -  History of severe episodes of ketosis requiring hospitalization in the last 6 months

 -  Active proliferative retinopathy, as defined by a photocoagulation or vitrectomy
 occurrence in the 6 months prior to visit 1, or any other unstable (rapidly
 progressing) retinopathy that may require photocoagulation or surgical treatment
 during the study. An ophthalmoscopic examination should have been performed in the 2
 years prior to study entry

 -  Pregnancy (women of childbearing potential must have a negative pregnancy test at
 study entry and a medically approved contraception method) or breastfeeding

 -  Treatment with systemic corticosteroids or medication known to influence insulin
 sensitivity in the 3 months prior to visit 1

 -  Treatment with antidiabetic drug other than insulin in the 3 months prior to visit 1

 -  Likelihood of requiring treatments during the study which are not permitted

 -  Treatment with an investigational product in the 30 days prior to visit 1

 -  History of sensitivity to the study drugs or to drugs with a similar chemical
 structure

 -  Presence of any condition (medical, including clinically significant abnormal
 laboratory test, psychological, social or geographical) actual or anticipated that the
 Investigator feels would compromise the patient safety or limit his/her successful
 participation in the study

 -  Night shift workers

 -  Impaired renal function as shown by serum creatinine ≥1.5 mg/dL (133 μmol/L) or ≥1.4
 mg/dL (124 μmol/L) in men and women, respectively

 -  Impaired hepatic function as shown by Alanine aminotransferase (ALT) and/or Aspart
 aminotransferase (AST) greater than three times the upper limit of normal range)

 -  Alcohol or drug abuse in the last year

 -  Mental condition rendering the patient unable to understand the nature, scope and
 possible consequences of the study
