Diabetes Mellitus, Type 1
Conditions
Brief summary
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
Detailed description
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.

Rate of Severe Symptomatic Hypoglycemia Per Patient-year
Severe symptomatic hypoglycemia is defined as an event with clinical symptoms that are considered to results from hypoglycemia in which the patient required assistance of another person and one of the following: * the event was associated with a measured blood glucose level below 36 mg/dL * or event was associated with prompt recovery after oral carbohydrate, intravenous glucose, or glucagon administration.
Time frame: over 13 weeks of each treatment period
Population: Analysis was performed on the Intention To Treat (ITT) population. The Intent-To-Treat population is composed of all randomized patients having received the 3 insulins (Insulin glulisine, aspart and lispro) N=256 patients: (sequence 1: N=86, sequence 2: N=86; sequence 3: N=84 patients).

Rate of Symptomatic Hypoglycemia With a Plasma Glucose (PG) ≤ 70 mg/dL Per Patient-year
Symptomatic hypoglycemia is defined as an event with clinical symptoms that are considered to results from hypoglycemia (confirmed or not by a glucose measurement) and associated with prompt recovery after oral carbohydrate administration.

Time Interval Between Infusion Set Changes: All Changes
Patients treated with insulin pump have to change their infusion set regularly (i.e.change was recommended every 48h). The patients were asked to report any change of their infusion set and the reason for change (routine basis or because of occurrence of a specific event such as occlusion, unexplained hyperglycemia or adverse event). All changes include all the changes whatever the reason such as routine or requested by occurrence of events.

Time Interval Between Infusion Set Changes in Routine
Patients treated with insulin pump have to change their infusion set regularly (i.e.change was recommended every 48h). The patients were asked to report any change of their infusion set and the reason for change (routine basis or because of occurrence of a specific event such as occlusion, unexplained hyperglycemia or adverse event). Changes in routine correspond to interval between changes according to patient use.
