Clinical Trial Summary

This study aims to determine whether dapaglfiflozin 12-week administration is associated with a beneficial impact on the vasculature of patients with chronic kidney disease.

Description:

A prospective, randomized, double-blind studies evaluating the impact of once-daily dapagliflozin 10 mg versus placebo for 12 weeks on endothelial function, as primary endpoint, will be conducted in 56 patients with chronic kidney disease (eGFR ≥25 and ≤60 mL/min/1.73m2 by CKD-EPI) and without diabetes (fasting glycemia≥1.26 mg/dL, oral hypoglycemic agents or insulin) on top of standard treatment (n=27 per group). Indexes of arterial stiffness, cardiovascular coupling, cardiac function and plasma concentrations of endothelial, inflammatory and oxidative stress biomarkers will be assessed as secondary endpoints. Patients will be recruited in the Departments of Cardiology and Nephrology of Rouen University Hospital. The study will include an inclusion visit (V1), 2 exploration visits performed before (V2) and 12 weeks (V3) after treatment initiation, and 1 output study (V4).

Intervention

Drug:
• Dapagliflozin 10Mg Tab
Patients receive dapagliflozin 10mg tablets once a day during 12 weeks
• Placebo
Patients receive placebo tablets once a day during 12 weeks

Procedure:
• impedance cardiography
impedance cardiography (PhysioFlow® PF-05 Lab1TM, Manatec Biomedical) is done for evaluation of cardiac function
• Applanation tonometry
Applanation tonometry will be done using SphygmoCor®, Hogimed) is done for evaluation of arterial stiffness
• post-ischemic hyperemia of forearm
An arterial occlusion cuff will be placed on the forearm, and will be deflated to allow post-ischemic hyperemia with the continuous measurements of brachial artery diameter and blood flow velocity by high-resolution echotracking coupled to a Doppler system (ArtLab system®)
• haemodynamics parameters
haemodynamics parameters will be evaluated using automatic oscillometric recorder
