Primary Objective:

To compare patient-led titration (intervention group) versus physician-led titration (usual standard of care) in optimizing the clinical use of insulin glargine in an Asian population of patients with Type 2 diabetes mellitus (T2DM) uncontrolled on oral antidiabetic drugs (OADs).

Secondary Objectives:

To determine the difference in glycemic control, safety, quality of life and treatment satisfaction between patient-led titration and usual care.

Inclusion criteria:

1. Diagnosed with T2DM duration of T2DM > 2 years
2. Insulin naïve
3. Continuous treatment with stable doses of 2 OADs (sulphonylureas, biguanides, alpha-glucosidase inhibitors, DPP-IV inhibitors, and glinides) for > three months prior to randomization
4. HbA1c levels 7% and 11 %
5. Body mass index (BMI) 20 and 40 kg/m2
6. Willing and able to perform blood glucose monitoring using a blood glucose meter

Exclusion criteria:

1. Diabetes other than type 2 diabetes (e.g. secondary to pancreatic disorders, drug or chemical agent intake),
2. Current or previous use of insulin (except for previous treatment of gestational diabetes or brief treatment with insulin for < 1 week),
3. Current treatment with thiazolidinediones,
4. Current or previous use (within the last 3 months) of GLP-1 receptor agonists or GLP-1 analogues,
5. Current or previous (within the last 3 months) use of any treatment for weight lost,
6. Active proliferative diabetic retinopathy,
7. Patient without any history of eye examination in the past 6 months,
8. Treatment with systemic corticosteroids in the 3 months prior to study entry,
9. Currently receiving treatment with monoamine oxidase inhibitors,
10. Currently receiving treatment with non-selective -blockers,
11. Treatment with any investigational product and/or device in the 2 months prior to study entry,
12. Likelihood of requiring treatment during the study period with drugs not permitted by the clinical trial protocol,
13. History of ketoacidosis or hyperosmolar hyperglycemic state,
14. History of stroke, myocardial infarction, angina pectoris, coronary artery bypass graft or percutaneous transluminal coronary angioplasty within the previous 12 months,
15. History of congestive heart failure,
16. History of hypoglycemia unawareness,
17. Unexplained hypoglycemia in the past 6 months,
18. Impaired renal function defined as, but not limited to, serum creatinine 1.5 mg/dL (133 mol/L) males or 1.4 mg/dL (124 mol/L) females or presence of macroproteinuria (>2gr/day),
19. Active liver disease (alanine transaminase ALAT greater than two times the upper limit of the reference range, as defined by the local laboratory),
20. Have any condition (including known substance or alcohol abuse or psychiatric disorder) that precludes the patient from following and completing the study protocol,
21. Had a blood transfusion or severe blood loss within the 3 months before screening, or have known hemoglobinopathy, hemolytic anemia or sickle cell anemia,
22. Known hypersensitivity / intolerance to insulin glargine or any of its excipients,
23. History of pancreatitis,
24. Currently undergoing therapy or planned radiological examinations requiring the administration of contrasting agents for malignancy (other than non-metastatic / early stage basal cell or squamous cell carcinoma),
25. Pregnant or lactating women (women of childbearing potential must have a negative pregnancy test at study entry and a medically approved contraception method),
26. Any medical condition that may have an influence on HbA1c rate.
