The Beta Cell Responsiveness to Glucose-dependent Insulinotropic Polypeptide (GIP) With and Without Sulfonylurea in Patients With Type 2 Diabetes

June 23, 2015 updated by: University Hospital, Gentofte, Copenhagen

Phase 2 Study of The Beta Cell Responsiveness to GIP With and Without Sulfonylurea in Patients With Type 2 Diabetes

The investigators hypothesize that the impaired insulinotropic effect of the incretin hormone GIP may be due to inadequate sensitization and ATP induced closure of beta cell K-ATP channels. By closing the channels through the use of sulfonylurea (SU) we hope to restore the insulinotropic effect of GIP.
