Effects of SGLT2 Inhibition on Myocardial Insulin Sensitivity

Summary

A Phase III, single-centre, randomized, 2-arm, parallel-group, double blind, placebo-controlled study, consisting of a screening phase (Days -14 to -1), a 4-week double-blind, placebo-controlled treatment phase and a 4-week follow-up phase. Subjects: Type 2 diabetic patients and coronary artery diseases (CAD) not requiring revascularization or underwent percutaneous coronary intervention (PCI) but clinically stable at time of screening visit, with suboptimal glycaemic control (HbA1c 7.0-8.5%) on their current anti-hyperglycaemic regimen Subjects will be randomized in a 1:1 ratio to dapagliflozin or placebo. Subjects will undergo screening assessment in the 14-day period preceding administration of the first dose of study drug on Day 1. The primary Objective is to assess the effect of dapagliflozin on myocardial insulin sensitivity The Secondary Objective is to assess global heart function, and metabolic systemic effects of dapagliflozin, and glycemic control. The study aims to enroll patients with type 2 diabetes with suboptimal glycemic control, and with coronary artery diseases (CAD) not requiring revascularization or underwent percutaneous coronary intervention (PCI) but clinically stable, who have already undergone, under routine cardiological assessment, a positron emission tomography (PET) 13NH3 scan in order to assess the cardiovascular function. Thus, the study aims to assess whether the improvement in cardiac metabolism obtained with dapagliflozin is greater than that obtained with normal clinical practice (according to Standards of Care).
