E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To test the hypothesis that a single dapagliflozin (10 mg) oral administration in subjects with or without type 2 diabetes and renal transplant will stimulate EGP and increase plasma glucagon concentration as compared to placebo. The same hypothesis will be tested in patients with T2DM and normal renal function, and then the differences (Dapagliflozin vs. placebo) will be compared between the two groups. |
Valutare l’ipotesi che una singola somministrazione per os di Dapagliflozin (10 mg) in pazienti con trapianto renale con o senza diabete tipo 2 stimoli l’EGP e la secrezione di glucagone rispetto a palcebo. La stessa ipotesi verra’ valutata in soggetti con diabete tipo 2 ma normale funzione renale quindi le differenze in termini di modulazione dell’EGP verra’ confrontata tra i due gruppi. |
|
E.2.2 | Secondary objectives of the trial |
To test the hypothesis that a single dapagliflozin (10 mg) oral administration in subjects with or without type 2 diabetes and renal transplant will modulate plasma glucose, insulin, c-peptide, FFA and blood pressure as compared to placebo. The same hypothesis will be tested in patients with T2DM and normal renal function, and then the differences (Dapagliflozin vs. placebo) will be compared between the two groups. |
Valutare l’ipotesi che una singola somministrazione per os di Dapagliflozin (10 mg) in pazienti con trapianto renale con o senza diabete tipo 2 moduli le concentrazioni plasmatiche di glucosio, insulina, c-peptide, FFA e la pressione arteriosa rispetto a palcebo. La stessa ipotesi verra’ valutata in soggetti con diabete tipo 2 ma normale funzione renale quindi le differenze verranno confrontate tra i due gruppi.
