E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine the effect of the combination of dapagliflozin (a SGLT2-inhibitor) and saxagliptin (a DPP-4 inhibitor) on pancreatic hormones secretion and endogenous glucose production in Type 2 diabetic subjects through comparison of the effects of co-administration of Saxagliptin and Dapagliflozin vs. Saxagliptin or Dapagliflozin alone |
Valutare l¿effetto della combinazione dapagliflozin (un inibitore SGLT2)/saxagliptin (un inibitore di DPP-4) sulla secrezione ormonale pancreatica e sulla produzione endogena di glucosio in soggetti affetti da diabete mellito tipo 2 rispetto all¿effetto esercitato dalla somministrazione delle singole componenti |
|
E.2.2 | Secondary objectives of the trial |
To determine whether the effect of the combination of dapagliflozin (a SGLT2-inhibitor) and saxagliptin (a DPP-4 inhibitor) on glucose, insulin, c-peptide, FFA, GIP, GLP-1, hepatic glucose production and beta-cell function is different as compared to single agent administration |
Valutare l¿ipotesi che la somministrazione combinata di saxagliptin e dapagliflozin moduli le concentrazioni plasmatiche di glucosio, insulina, c-peptide, FFA, GIP, GLP-1, la produzione epatica di glucosio e la funzione cellulare in maniera differente rispetto alla somministrazione delle singole componenti |
