Primary Objective:

• To assess the efficacy of insulin glargine as measured by changes of HbA1c levels from baseline in type 2 diabetes mellitus (T2DM) patients following GLP-1 failure.

Secondary Objective:

• To determine the change in glycemic control, safety, and treatment satisfaction in insulin glargine use in patients following GLP-1 failure.

Inclusion criteria:

• Patients of aged ≥30 and ≤75 years with type 2 diabetes mellitus (T2DM)
• Hemoglobin A1c (glycosylated hemoglobin; HbA1c) levels measured at screening ≥7.5%
• Continuous treatment with stable doses of GLP-1 analogue for >3 months prior to enrollment (for patients also using oral anti-hyperglycemic drugs [OADs], continuous treatment with stable doses of OADs for >3 months prior to enrollment)

Exclusion criteria:

• Inpatient with T2DM
• Diabetes other than T2DM (e.g. secondary to pancreatic disorders, drug or chemical agent intake)
• Fasting plasma glucose (FPG) levels <130mg/dL
• Body mass index (BMI) >28 kg/m2
• Patients using thiazolidinediones in the last 3 months prior to enrollment
• Use of any treatment for weight loss in the last 3 months prior to enrollment
• Treatment with systemic corticosteroids within the 3 months prior to enrollment
• Patients using non-selective ß-blockers
• Likelihood of requiring treatment during the study period with drugs not permitted by the clinical trial protocol
• Most recent ophthalmologic examination >6 months prior to enrollment
• Diabetic retinopathy with surgical treatment (last photocoagulation or vitrectomy) in the 3 months before enrollment or which may require surgical treatment
• Proliferative diabetic retinopathy or any other unstable rapidly progressive retinopathy
• Impaired renal function defined as, but not limited to, serum creatinine ≥1.3 mg/dL [males] or ≥1.2 mg/dL [females] or presence of macroproteinuria (>1 g/day)
• Active liver disease including hepatic cirrhosis, hepatic failure, and hepatitis or alanine transaminase (ALT) or aspartate aminotransferase (AST) >2 times upper limit or total bilirubin >1.5 times upper limit of normal (except in case of Gilbert's syndrome) at enrollment
• Have any condition (including known substance or alcohol abuse or psychiatric disorder) that precludes the patient from following and completing the study protocol
• Any medical condition that may have an influence on HbA1c rate
• Currently undergoing therapy for malignancy which may affect the study evaluation
• Use of any investigational product and/or device within the 2 months prior to enrollment
• History of ketoacidosis or hyperosmolar hyperglycemic state during the previous 12 months prior to enrollment
• History of stroke, myocardial infarction, angina pectoris, coronary artery bypass graft or percutaneous transluminal coronary angioplasty within the previous 12 months prior to enrollment
• History of congestive heart failure
• History of hypoglycemia unawareness or unexplained hypoglycemia during the previous 12 months prior to enrollment
