Dapagliflozin for Cardio-renal Protection After ICU Discharge

Overview

Several millions of patients are admitted to ICUs in Europe or USA each year. We and others, have shown that patients discharged from intensive care units (ICU) have a high incidence of cardiovascular and/or renal events and high mortality rate (22%) during the year following ICU discharge. Furthermore, a very recent meta-analysis found an excess hazard of late cardiovascular events which persists for at least 5 years following hospital discharge in sepsis survivors. Hence, many international ICU societies recommended investigating and improving post-ICU outcome with scarce guidance. We demonstrated that the proportion of ICU patients dying or presenting cardiovascular events within the year following ICU discharge is reported \~25% \[2\], reaching \~40% in some studies when considering patients with acute kidney injury (AKI). Plasma biomarkers at ICU discharge have good predictive value and patients with increased kidney or cardiovascular biomarkers display high risk of such events. In addition, we and others demonstrated that AKI or sub-AKI (patient not meeting the AKI definition but with an increased kidney related biomarker) could induce remote cardio-vascular injury and fibrosis, which may be involved in the poor long-term prognosis of ICU-acquired AKI. We hypothesize that strategy that prevent worsening in cardiovascular and/or renal injuries and/or in cardiovascular consequences of sub-AKI and AKI after ICU discharge improve long-term outcomes in ICU survivors. SGLT2 inhibitors are widely recognized as key drugs to protect the kidney and/or the myocardium in chronic diseases such as diabetes or heart failure. Cardio protective effect of SGLT2 inhibitors is optimal in patients with higher cardiac biomarker.

Phase III study Prospective, multicenter, superiority, double-blind, randomized controlled study with two arms (1:1). Every patient will be screened in the 48h before ICU discharge for trial inclusion and non-inclusion criteria until 72h hours after ICU discharge. After providing written informed consent, patients will be randomly assigned to receive either dapagliflozin (at a dose of 10 mg once daily) or matching placebo, in accordance with the sequestered, fixed-randomization schedule, with the use of balanced blocks to ensure an approximate 1:1 ratio of the two regimens for one year. Four visits are planned, one at inclusion (V0), one at 6 months (V1), one at the end of the treatment (V2 at one year), one 6 weeks after the end of the treatment (V3, end of the study) and two phone calls at 3 (Phone call 1) and 9 months (phone call 2). At 6 months (V1) and at 12 months (V2) visits, a clinical exam and biological analysis will be performed at hospital (i.e., HbA1c, glucose level, ionogram, NT-proBNP or BNP, serum creatinine, hematocrit and pregnancy urinary test) by anesthesiologists, cardiologists or nephrologists, to assess primary and secondary endpoints, including eGFR. At 12 months + 6 weeks (V3) visit, a clinical exam and biological analysis will be performed at hospital (i.e., glucose level, NT-proBNP or BNP, serum creatinine) by anesthesiologists, cardiologists or nephrologists, to assess primary and secondary endpoints, including eGFR. The phone calls, at 3 and 9 months, will be made by the designated persons and respecting the confidentiality and security of the data collected. At inclusion (V0) and at 6 months (V1) the treatment will be deliver for the next 6 months. At 6 months (V1), the patient will pick up his treatment at the hospital. Primary endpoints will be assessed at 6 and 12 months visit and phone calls (3 and 9 months). Secondary endpoints will be assessed at each visit and phone calls (3, 6, 9, 12 and 12 + 6 weeks). eGFR (glomerular filtration rate) will be assessed only at 6, 12 months and 12 + 6 weeks. The eGFR (glomerular filtration rate) will not be assessed at phone calls. At each visit and phone calls, adverse events and severe adverse events will also be assessed.
