Brief Summary

The chemokine CXCL8 plays a key role in the recruitment and activation of polymorphonuclear neutrophils in post-ischemia reperfusion injury after solid organ transplantation. Reparixin is a novel, specific inhibitor of CXCL8. This study is configured to explore the safety and efficacy of reparixin in preventing the delayed graft function (DGF) after kidney transplantation.

Detailed Description

Delayed graft function (DGF) is the most common allograft complication in the immediate kidney post-transplant period, affecting 25-35% of all patients who receive a cadaver graft, but rates up to 50% have been reported, especially in recipients of kidneys from marginal donors. It is an important clinical complication as it requires dialysis, prolongs hospitalisation, raises the cost of transplantation, and makes more difficult the management of immunosuppressive therapy. Although the effects of DGF on long-term graft function are still debated, there is overall increasing evidence that DGF reduces long-term graft survival. Moreover, given the well documented impact of acute rejection on long-term graft survival, it is conceivable that DGF and acute rejection synergize in negatively influencing long-term graft survival. Kidney reperfusion, after long cold ischemia period, is associated with an inflammatory reaction characterized by massive polymorphonuclear leukocyte (PMN) infiltration both at the glomerular and tubular levels. The importance of CXCL8 in recruiting PMN in kidney tissue during the ischemic time and after reperfusion has been clearly documented.

The efficacy of reparixin in preventing PMN infiltration and tissue damage in rat models of kidney transplantation and lung transplantation, as well as the safety shown in human phase 1 studies, provide the rationale for a clinical study aimed at evaluating the effect of reparixin in preventing DGF after kidney transplantation

Primary Outcome Measures
NameTimeMethod
Creatinine Clearance (CrCl) in the Immediate Post-transplant Period1-3 and 10-12 hours post allograft reperfusion

CrCl was determined by two 60 minute urine collections, during the time intervals 1-3 and 10-12 hours of allograft reperfusion. Blood was withdrawn at the midpoint of each urine collection. CrCl at each timepoint was calculated according to the formula:

creatinine clearance (mL/minutes) = urine creatinine (mmol/L) x urine volume (mL) / serum creatinine (mmol/L) x time of collection (minutes) An average was to be calculated from the two 60 minute values in each interval.

Secondary Outcome Measures
NameTimeMethod
Number of Patients Requiring Dialysis Within 7 Days Post-transplantup to day 7 post-transplant

The number of patients who required dialysis within 7 days post-transplant was evaluated.

Renal Function Tests - Serum Creatininedaily up to day 7 post-transplant or hospital discharge

Serum creatinine (SrCr) was measured daily from Day 1 up to 7 days post-transplant or up to hospital discharge, whichever occurred earlier; in patients undergoing dialysis, SrCr values were measured immediately before dialysis.

Renal Function Tests - Calculated Glomerular Filtration Ratefrom Day 1 up to 7 days post-transplant or up to hospital discharge

Calculated glomerular filtration rate (GFR) was measured daily from Day 1 up to 7 days post-transplant or up to hospital discharge, whichever occurred earlier; in patients undergoing dialysis, SrCr values were measured immediately before dialysis

Renal Function Tests - Urine Outputfrom Day 1 up to 7 days post-transplant or up to hospital discharge

Urine output, measured in the interval from transplant to 8:00 of Day 1, and then daily from Day 2 up to 7 days post-transplant or up to hospital discharge, whichever occurred earlier

Duration of Hospital Stayfirst 30 days post-transplant

The mean duration of hospital stay was evaluated.

Acute Rejection Episodes at Month 6 and Between Month 6 and Month 12at Month 6 and between Month 6 and Month 12

Acute rejection defined as an increase in serum creatinine level after exclusion of other causes of graft dysfunction, accompanied by a sudden decline in glomerular filtration rate and renal function and well-established diagnostic features on kidney allograft biopsy which can be either antibody-mediated and/or T cell-mediated and can occur at any time after transplant.

Graft Survival Rateat Month 1, Month 6 and Month 12

Graft failure was defined as the failure of graft function for any reason, ultimately requiring renal replacement therapy and/or retransplantation (United States Renal Data System \[USRDS\] 2017.

Number of Days on Dialysis Before Resuming Kidney Functionup to Day 7 post-transplant

the number of days on dialysis before resuming kidney function was evaluated.

Number of Patients With Immediate, Slow and Delayed Graft Functionday 5 post-transplant

The number of patients who required dialysis within 7 days post-transplant was evaluated.

Immediate graft function: SrCr ≤3 mg/dL on post operative day 5) Slow graft function: SrCr \>3 mg/dL dL on post operative day 5, no need of dialysis) Delayed graft function: Dialysis needed in the first week)

Mortalityfirst 30 days post-transplant

Mortality in the first 30 days post-transplant was evaluated.

Serum Creatinine at Month 1, Month 6 and Month 12at Month 1, Month 6 and Month 12

Serum creatinine (SrCr) was measured at Month 1, Month 6 and Month 12.

Calculated Serum Creatinine Clearance at Month 1, Month 6 and Month 12at Month 1, Month 6 and Month 12

Creatinine clearance (CrCl) is the volume of blood plasma cleared of creatinine per unit time. It is a rapid and cost-effective method for the measurement of renal function.

Patient Survival Rateat Month 1, Month 6 and Month 12

Numbers of patients alive, dead, and lost to follow up are reported.
