Vascular Impact of Dapagliflozin in CKD Patients (DAPAVASC)

Phase 2
Conditions
Renal Insufficiency, Chronic
Interventions
Drug: Placebo
Procedure: impedance cardiography
Procedure: Applanation tonometry
Procedure: post-ischemic hyperemia of forearm
Procedure: haemodynamics parameters
Registration Number
NCT04930549
Lead Sponsor
University Hospital, Rouen
Brief 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.

Detailed 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).
