Comparison of the Efficacy and Safety of a New Formulation of Insulin Glargine With Lantus in Patients With Type 2 Diabetes Insufficiently Controlled With Non-insulin Antidiabetic Therapy

Inclusion criteria : * Adult patients with type 2 diabetes mellitus inadequately controlled with non-insulin antihyperglycemic drug(s). * Signed written informed consent. Exclusion criteria: * Age \< legal age of adulthood. * HbA1c \<7.0% (\<53 mmol/mol) or \>11% (\>97 mmol/mol) (at screening). * History of type 2 diabetes mellitus for less than 1 year before screening. * Less than 6 months before screening with non-insulin antihyperglycemic treatment. * Change in dose of non-insulin antihyperglycemic treatment in the last 3 month before screening. * Initiation of new glucose-lowering medications and/or weight loss drug in the last 3 months before screening visit and/or initiation of glucagon like peptide-1(GLP-1) receptor agonist in the last 6 months before screening visit. * Patients receiving only non-insulin antihyperglycemic drugs not approved for combination with insulin according to local labeling (Note: non-insulin antihyperglycemic drugs not approved for combination with insulin are to be discontinued at randomization). * Current or previous insulin use except for a maximum of 10 consecutive days (eg, acute illness, surgery) during the last one year prior to screening. * 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.
