Beskrivelse
Inclusion Criteria:
- Males and females aged 40 to 80 years
- Diagnosis of type 2 diabetes mellitus for at least 6 months
- Body mass index (BMI) ≥25kg/m2
- 7%≥HbA1c ≤ 9% at visit 2
- Treatment with metformin between 1.7g/day and 3g/day for at least 12 weeks prior to visit 1
- Female subjects must be non-pregnant, post-menopausal, surgically sterile or using effective contraceptive measures
- Written informed consent
Exclusion Criteria:
- Use of any oral antidiabetic drug other than metformin within 12 weeks prior to screening
- Significant hypersensitivity to thiazolidinediones and sulfonylureas or compounds with similar chemical structure
- Subjects who have required the use of insulin for glycaemic control at any time in the past or subject with a history of metabolic acidosis including diabetic ketoacidosis
- Subjects with clinically significant ongoing oedema or with a history of oedema in the 12 months prior to visit 1
- Subjects with a history of severe hypoglycaemia
- Anemia defined by haemoglobin concentration <11.0g/dL for males or <10.0g/dL for females
- Renal disease or renal dysfunction, e.g. as suggested by serum creatinine levels ≥135µmol/L in males and ≥110µmol/L in females
- Presence of clinically significant hepatic disease (i.e. ALT, AST, total bilirubin or alkaline phosphatase >2.5 times the upper limit of the normal reference range)
- Congestive heart failure (NYHA class I to IV), unstable or severe angina, recent myocardial infarction
- Subjects with chronic diseases requiring periodic or intermittent treatment with oral or intravenous corticosteroids
- Female who are lactating, pregnant, or planning to become pregnant
- Any clinically significant abnormality identified at screening which in the judgement of the investigator makes the subject unsuitable for inclusion in the study (e.g. physical examination, laboratory test, ECG, ...)
- Use of any investigational agent within 30 days or 5 half-lives (whichever is longer) prior to enrolment in this study
- Active alcohol, drug or medication abuse within the last 6 months or any condition that would indicate the likelihood of poor subject compliance
