E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Aim of this project will be to evaluate the effect short-term (4 weeks) administration of dapagliflozin as compared to a thiazide diuretic on endothelial function as flow mediated dilation (FMD) of the brachial artery. |
Valutare la variazione della funzione endoteliale dell’arteria brachiale, misurata come flow mediated dilation (FMD) dopo 4 settimane di terapia con dapagliflozin o idroclorotiazide (studio principale “short term”) |
|
E.2.2 | Secondary objectives of the trial |
a) To assess the effects of short-term (4 weeks) treatment period with the two treatments on the following parameters: • Renal Resistive Index (RRI) before and after nitrate administration • Endothelial function as flow mediated dilation (FMD) of brachial artery • Carotid to femoral pulse wave velocity • Peripheral and Central BP measurement • 24h BP monitoring • 24h urinary albumin excretion • 24h diuresis for glucose, Na, K, Cl, Ca, Mg urinary excretion determination • Free water clearance and Na fractional excretion • PRA, aldosterone, catecholamines plasma levels • Daily glucose profile (7 determination in a day) Safety objective • Adverse events and adverse drug reactions • Estimated glomerular filtration rate (eGFR) (based on CKD-EPI formula starting from serum creatinine) • Routine laboratory parameters (haematology, blood chemistry and urinalysis). |
a) Valutare la variazione dopo 4 settimane (studio principale “short term”) di terapia con i due trattamenti dei seguenti parametri : • indici di resistività intraparenchimale renale (RRI) prima e dopo somministrazioni di nitrati • velocità dell’onda di polso carotido-femorale • pressione arteriosa clinica e centrale • pressione aretriosa monitorata delle 24 ore • escrezione urinaria delle 24 ore di albumina • escrezione urinaria delle 24 ore di Na, K, Cl, Ca, Mg • clearance dell’acqua libera, escrezione frazionata di sodio • PRA, aldosterone e catecolamine plasmatiche • marcatori plasmatici di stress ossidativo e attivazione e danno endoteliale • profilo glicemico giornaliero (7 determinazioni giornaliere). Obiettivi di sicurezza: • eventi avversi, reazioni avverse al farmaco • funzione renale (filtrazione glumerulare stimata, eGFR, basata sulla cretatininemia e la formula CKD-EPI) • esami ematochimici e urinari di routine (emocromo, biochimica clinica e analisi delle urine). |
