Study setting(s)Not specified
Study typeTreatment
Scientific title
Study objectivesBy inducing a shift of fat out of the visceral compartment - among which the pancreas - into the subcutaneous compartment, rosiglitazone results in improved pancreatic beta-cell function in type 2 diabetes patients, as compared to a sulfonylurea derivative, while both groups continue metformin treatment.
Ethics approval(s)Received from local medical ethics committee
Health condition(s) or problem(s) studiedDiabetes mellitus type II (DM type II)
InterventionPatients will be randomised to 26 weeks of treatment with metformin with glimepiride 4 mg a day or metformin with rosiglitazone 8 mg a day. Before the start of the treatment patients will undergo a 200 minute hyperglycaemic (aiming at 15 mmol/l) clamp with administration of glucagon-like peptide-1 (GLP-1) starting at 120 minutes and an arginine bolus at 180 minutes to elicit a further beta-cell response. Twenty-six weeks later, the assessments will be repeated, again on metformin, other study medication taken until the morning before this assessment.
