Brief Summary:
The objective of this study is to investigate the potential GLP-1-mediated contribution to the well-established glucose-lowering effect of sevelamer-induced bile acid sequestration . Exendin9-39 has been demonstrated to act as a potent and specific GLP-1 receptor antagonist with no partial agonistic potential and is considered a useful tool in the assessment of GLP-1 physiology. The aim is to evaluate any contribution of sevelamer-induced GLP-1 secretion to the reduced plasma glucose concentrations observed after treatment with sevelamer. A randomised placebo-controlled cross-over study involving two 17-day treatment periods with sevelamer and placebo, respectively, in metformin-treated patients with type 2 diabetes, will be conducted. The impact of bile acid sequestration on GLP-1 secretion and effect will be examined during two randomised experimental days after 15 and 17 days of treatment with sevelamer (1,600 mg three times a day) and placebo, respectively. During each of these two experimental days, a meal test with concomitant exendin9-39 infusion or placebo will be performed (for evaluation of any GLP-1-mediated effects). Postprandial plasma glucose excursion is the primary endpoint, and secondary endpoints include postprandial plasma/serum excursions of insulin, C-peptide, GLP-1, glucagon, glucose-dependent insulinotropic polypeptide (GIP), glucagon-like peptide-2 (GLP-2), peptide YY (PYY), oxyntomodulin, ghrelin, fibroblast growth factor (FGF)-19, FGF-21, C4 (an intermediate in the de novo synthesis of bile acids), cholecystokinin (CCK), bile acids and plasma lipids. Furthermore, gastric emptying, gallbladder emptying, liver fat content, appetite and ad libitum food intake will be examined.
