Efficacy Study on the Control of Blood Glucose Concentration in Type 1 Diabetic Patients

• Status: Completed
• Trial end date: 2008-09-01
• Target enrollment: 0
• Participant gender: All

Summary

·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:

Efficacy:

• 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.

Tolerance:

• To record undesirable events

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

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Sanofi
• Treatments: Insulin; Insulin Detemir; Insulin Glargine; Insulin glulisine; Insulin, Globin Zinc

Criteria

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.
