Efficacy and Safety of Insulin Glargine in Patients With Type 2 Diabetes With Inadequate Control on DPP-4 Inhibitor Therapy

28 weeks (Screening: About 2 weeks/Treatment: 24 weeks (6 months)/Follow-up: 2 weeks)

Inclusion criteria

• Patients with type 2 Diabetes mellitus ≥ 20 aged
• Patients who are treated with DPP- 4 for at least 3 months before informed consent with metformin plus or minus sulphonylurea inadequately controlled with HbA1c ≥ 7.5%
• Be able and voluntarily agree to participate in this study by signing a written informed consent

Exclusion criteria

• Diabetes patients other than Type 2 (eg. Type 1 Diabetes mellitus, pancreatic disease, secondary diabetes)
• HbA1c > 11% at screening
• History of continuous basal insulin treatment within 1 year before screening
• History of diabetic acidosis (including keto-acidosis) within 1 year before screening
• History of myocardial infarct, stroke or heart failure related admission within 3 months before screening
• History of drug or alcoholic abuse within 6 months before screening
• Weight change ≥ 5 kg within 3 months before screening
• History of hypoglycemic unawareness
• Systolic blood pressure >180 mmHg or diastolic blood pressure > 110 mmHg regardless of taking anti-hypertensive, or uncontrolled hypertension
• Active malignant cancer, major systemic disease, clinically significant diabetic retinopathy, macular edema necessitating laser treatment, abnormal clinical finding from physical examination, lab analysis, electrocardiogram or vital sign, which can be regarded as to prevent safe completion of clinical study or to make efficacy assessment difficult by investigator or co-investigator at screening
• Pregnant or lactating women
• Women of child bearing potential (Pre-menopause or not surgically infertile within 3 months before screening) who match two conditions below:
• Negative serum pregnancy test at screening
• Using medically proven effective contraceptive method
• Hypersensitivity to investigational drugs
• Lab finding at screening:
• Abnormal liver function: Alanine transaminase or Alkaline phosphatase > 3 times of upper limit of normal range
• Renal insufficiency: Men with serum Cr ≥ 1.5 mg/dL (≥ 133µmol/L), women with serum Cr ≥ 1.4 mg/dL (≥ 124 µmol/L)
• Use of anti-obese drug within 3 months before screening
• Has been using drugs that can influence glucose metabolism (systemic corticosteroid, thyroid hormone) within 3 months before screening or has possibility of using these drug during the investigational period
• Has participated in clinical studies of any investigational drugs within 3 months before screening
• Considered not physically or psychologically appropriate to participate in clinical study by investigator
• Not willing to comply with scheduled visit, self-inject insulin, or self-monitor blood glucose level
