Comparison of a New Formulation of Insulin Glargine With Lantus® Both in Combination With Oral Antihyperglycemic Drug(s) in Japanese Patients With Type 2 Diabetes Mellitus

A 6-Month, Multicenter, Randomized, Open-label, Parallel-group Study Comparing the Efficacy and Safety of a New Formulation of Insulin Glargine and Lantus® Both in Combination With Oral Antihyperglycemic Drug(s) in Japanese Patients With Type 2 Diabetes Mellitus With a 6 Month Safety Extension Period

Primary Objective:

To compare the efficacy of a new formulation of insulin glargine and Lantus in terms of change of HbA1c from baseline to endpoint (scheduled at month 6 [week 26]) in japanese patients with type 2 diabetes mellitus.

Secondary Objectives:

To compare a new formulation of insulin glargine and Lantus in terms of change in fasting plasma glucose (FPG), preinjection plasma glucose, 8-point self-measured plasma glucose (SMPG) profile.

To compare a new formulation of insulin glargine and Lantus in terms of occurrence of hypoglycemia

The duration of study will consist of:

• Up to 2-week screening period;
• 6-month open-label comparative efficacy and safety treatment period;
• 6-month open-label comparative safety extension period;
• 4-week post-treatment safety follow-up period

Inclusion criteria :

o Patients with type 2 diabetes mellitus diagnosed for at least 1 year at the time of screening visit treated with basal insulin in combination with oral antihyperglycemic drugs (OADs) for at least 6 months before screening visit;

Exclusion criteria:

• Age < 18 years at screening visit;
• BMI(body mass index) ≥ 35 kg/m2 at screening visit;
• HbA1c < 7.0% or > 10% (national glycohemoglobin standardization program [NGSP] value) at screening visit;
• Diabetes other than type 2 diabetes mellitus;
• Patients on self-monitoring of blood glucose less than 6 months before screening visit;
• Patients using pre-mix insulins, insulin detemir at 2 times or more a day, or GLP 1 receptor agonists in the last 3 months before screening visit;
• Patients using mealtime insulin (rapid-acting insulin analogue and short-acting insulin) for more than 10 days in the last 3 months before screening visit;
• Use of insulin pump in the last 6 months before screening visit;
• Initiation of new glucose-lowering medications and/or weight loss drugs in the last 3 months before screening visit;
• Severe hypoglycemia resulting in coma/seizures, and/or hospitalization for diabetic ketoacidosis in the last 6 months before screening visit;
• Unstable proliferative diabetic retinopathy or any other rapidly progressive diabetic retinopathy or macular edema likely to require treatment (eg, laser, surgical treatment or injectable drugs) during the study period.
