Sanofi Identifier:
First received: December 29, 2005
Last updated: December 4, 2009
Last verified: December 2009

·Main objective: To compare the variability of fasting capillary blood glucose concentration, observed with insulin glargine combined with insulin glulisine and with insulin detemir combined with insulin glulisine, in type 1 diabetics. It is a non-inferiority study.

·Secondary objectives:


  • To compare the variability of blood glucose concentration before the evening meal, observed with insulin glargine combined with insulin glulisine and with insulin detemir combined with insulin glulisine, in type 1 diabetics.
  • To record the intra- and inter-daily variability using the MAGE and MODD indices [1,2,3,4]
  • To compare the glycaemic profiles (7 points)
  • To evaluate the HbA1c concentration, at the end of each period of treatment, weight change, the dose of insulin used and the number of daily injections.


  • To record undesirable events
  • To evaluate the safety in use from the record of episodes of hypoglycaemia (symptomatic, diurnal, nocturnal, severe).

Enrollment: 88
Study Start Date: October 2005
Study Completion Date: September 2008
Primary Completion Date: September 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: I Drug: insulin glulisine / insulin glargine
insulin glargine administered subcutaneously by the patient once a day, in the evening, between 18.30 and 24.00
Active Comparator: II Drug: insulin glulisin / insulin detemir

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria :

  • Belonging to a social security scheme or covered by such a scheme
  • With type 1 diabetes (defined as a concentration of C-peptide < 0.1 nmol//l and a fasting blood glucose of >= 1.26 g/l), diagnosed not less than 5 years previously
  • Treated for at least 6 months by intensive insulin treatment, following a basal-bolus system, using insulin glargine (Lantus®) as basal insulin. During the study, this insulin will administered in the evening
  • Trained in the titration of prandial insulin (the dose of rapid insulin decided at each mealtime depending on the composition of the meal)
  • With an HbA1c level of <= 8.5% at the inclusion visit
  • Capable of checking their blood glucose concentration using the material supplied by the sponsor: blood glucose meter and patient notebook
  • Able to eat 3 regular daily meals on the days for recording the blood glucose cycle and similarly as much as possible on other days throughout the length of the study
  • Able to continue their usual daily activities during the study
  • Women of child-bearing potential should be using an effective method of contraception
  • Fundal examination result less than a year old available

Exclusion Criteria:

  • Recent history of severe hypoglycaemia (at least 2 events in the 6 months prior to inclusion)
  • An episode of acidocetosis in the 3 months prior to inclusion
  • Proliferating retinopathy, defined as having required treatment by surgery or photocoagulation, in the 6 months prior to visit 1, or non-stabilised (rapidly developing) retinopathy which may require photocoagulation or surgery
  • Pancreatectomy
  • Altered hepatic function (AST or ALT >= 2.5 x normal, in the initial measurements)
  • Altered renal function (plasma creatinine > 1.5 mg/dl)
  • Acute infection
  • Acute or chronic metabolic acidosis
  • Gastroparesis
  • History of cancer in the last 5 years
  • Medically significant cardiovascular, hepatic, neurological or endocrine disease or any other significant disease making carrying out the protocol or interpreting the trial results difficult
  • History of drug or alcohol abuse
  • Subject likely to receive treatment during the trial which is not authorised in the protocol (see Section 6.2), in particular, treatment by corticosteroids whatever the route of administration or dose.
  • Antidiabetic treatment by products other than those supplied within the framework of this study
  • Treatment by another product undergoing development during the 3 months prior to inclusion in the trial
  • Hypersensitivity to one of the study products (insulin glargine, insulin detemir, insulin glulisine) or to one of the excipients present in the insulin preparations, used in the study
  • Working at night
  • Pregnancy
  • Breast-feeding
  • Mental state making the subject incapable of understanding the objectives and possible consequences of the trial
  • Subject unable to submit to the restrictions of the protocol (e.g. uncooperative, incapable of attending monitoring visits and probably incapable of finishing the trial)
  • Subject deprived of his liberty because of an administrative or legal decision
  • The investigator or any member of the team or close to the investigator directly implicated in the trial particularly assistant doctors, pharmacists, nurses, trial coordinator, etc.
