About this study
Official title: A Multicenter, Open-label, Randomized Pilot Clinical Study of Efficacy and Safety of Reparixin for Prevention of Early Allograft Dysfunction in Patients Undergoing Orthotopic Liver Transplantation
The objective of the study is to evaluate the efficacy and safety of Reparixin treatment (2.772 mg/kg body weight/hour intravenous continuous infusion for 7 days) based on incidence of early allograft dysfunction within the first 7 days after orthotopic liver transplantation (OLT) and overall indicators of allograft dysfunction in the early postoperative period (within 14 days after the OLT).
Read the detailed description
The study is a phase 2, multicenter, open-label, randomized pilot study to evaluate the efficacy and safety of Reparixin for prevention of early allograft dysfunction in patients undergoing orthotopic liver transplantation.
All the patients who participated in the study received standard immunosuppressive therapy in accordance with the Russian Transplant Society Guidelines for liver transplantation (2013). The study was planned to be conducted at 5-8 transplantation sites in Russia and Belarus. Recruitment was competitive among the study sites so that patients were screened and if eligible, randomized consecutively until the randomization was stopped.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ReparixinDrug
Reparixin was administered as a continuous intravenous infusion for 7 days (Day 0 to Day 6) (168 hours).
Reparixin was provided as 33 mg/ml concentrated solution to be diluted for i.v. infusion, packaged into 250 mL clear glass vials. To give a final concentration of 11 mg/mL, the content of a vial (250 ml) was diluted with 500 ml of 0.9% sterile saline to a total volume of 750 ml. The dosing solution was placed in a 1000 ml sterile empty Infusion Bag. Dosing solutions were to be used within 72 h from preparation, unless more restrictive rules.
Reparixin infusion started approximately 60-90 minutes before the anticipated time of OLT. Infusion interruption was allowed for no more than 60 min.
All patients received standard immunosuppressive therapy in accordance with the Russian Transplant Society Guidelines for liver transplantation.
Patients and allograft survival were monitored up to 1 year after OLT.
ControlOther
The patients who were randomized in the control group, did not receive any study therapy. The patients of both groups received the standard immunosuppressive therapy with Tacrolimus only or together with mycophenolates, or a combination of Tacrolimus/Cyclosporine with mycophenolates and/or glucocorticosteroids. The patients with hepatocellular carcinoma and impaired renal function could receive a combination of drugs that includes everolimus. Basiliximab in association with methylprednisolone was used for the induction of immunosuppression.

What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of EAD (Early Allograft Dysfunction) Within 7 Days After OLT (PP Population)
Assessment of the frequency of early allograft disfunction (EAD) after orthotopic liver transplantation (OLT) (Day 7 of Week 1) among patients who received Reparixin and patients in the control group. EAD was defined according to standard criteria as maximum Alanine Transferase (ALT) or Aspartate Transferase (AST) levels on days 1-7 of >2000 U/L, day 7 Bilirubin level ≥10 mg/dl, or a day 7 International Normalized ratio (INR) ≥1.6.
Taking into account that 5 out of 22 patients in the Reparixin group experienced EAD during the first stage of the study, according to the Protocol and the DMC conclusion, it was decided on the early termination of the study.
Measured: within 7 day after the OLT
Incidence of EAD (Early Allograft Dysfunction) Within 7 Days After OLT (mITT Population)
Assessment of the frequency of early allograft disfunction after orthotopic liver transplantation (OLT) (Day 7 of Week 1) among patients who received Reparixin and patients in the control group. EAD was defined according to standard criteria as maximum Alanine Transferase (ALT) or Aspartate Transferase (AST) levels on days 1-7 of >2000 U/L, day 7 Bilirubin level ≥10 mg/dl, or a day 7 International Normalized ratio (INR) ≥1.6.
Please note that taking into account that 5 out of 22 patients in the Reparixin group experienced EAD during the first stage of the study, according to the Protocol and the DMC conclusion, it was decided on the early termination of the study.
Measured: within 7 day after the OLT
Secondary outcomes (20)
Number of Patients With/Without Primary Allograft Nonfunction Within 7 Days After OLT
The number of patients in which: a) the primary allograft nonfunction within 7 day after the OLT was determined and not determined, and the number of patients in which 2)Appropriate data was not available in each of the two arms are reported.
Measured: Within 7 days after OLT
Number of Patients With/Without Overall Indicators of Allograft Dysfunction During the Early Postoperative Period
The number of patients in which: a) the primary allograft dysfunction within 14 day after the OLT was determined and not determined, and the number of patients in which 2)Appropriate data was not available in each of the two arms are reported. The term "early allograft dysfunction" (EAD) identifies liver transplant (LT) allografts with initial poor function and portends poor allograft and patient survival.
Measured: Within 14 days after OLT
Overall Indicators of the Allograft Dysfunction During the Early Postoperative Period - Extracorporeal Detoxification
Cumulative incidence of extracorporeal detoxification as an indicator of liver allograft dysfunction in early postoperative period within 2 weeks after OLT is reported. Extracorporeal liver support describes all measures of extracorporeal blood treatments, which are aimed at supporting any functions of the liver in order to reduce the number of failing organs as a consequence of liver failure. The ultimate goal of extracorporeal liver support is to prolong the survival time of patients with liver failure by preventing progression of secondary organ failure.
Measured: Within 14 days after OLT
Frequency of Identification of Laboratory Examination Values
The frequency of identification of laboratory examination values corresponding to early allograft dysfunction within 3 days after the operation (Day 4 of the study drug administration)
Measured: within 3 day after the OLT
Number of Patients With Early Allograft Dysfunction (EAD) in Case of Transplantation of Donor Organs, by the Degree of Steatosis
Incidence of early allograft dysfunction in case of transplantation of donor organs differing by the degree of steatosis was reported.
The investigators evaluated organ suitability for transplantation relying on histopathologic findings from biopsy. In this clinical setting, grafts with macrovesicular steatosis degree >50% were considered as non-suitable for transplantation.
Steatosis or fatty liver disease (NAFLD) is characterised by hepatic lipid accumulation. Nominal data for the MITT are reported.
Measured: Within 14 days after OLT
Number of Patients With EAD in Case of Transplantation of Donor Organs Differing by the Time (in Hours) of Allograft Removal From the Donor and up to Its Reperfusion (Duration of Cold Ischemia)
Number of patients with EAD in case of transplantation of donor organs by the time of allograft removal from the donor and up to its reperfusion after engraftment (duration of cold ischemia) was assessed.
Cold ischemia time during procurement is defined as the time after clamping of aorta until excision of the organ, which can last some hours. Prolonged cold ischemia time is an independent risk factor for the development of delayed function and primary nonfunction of the allograft. Although the exact mechanism is unknown, cold ischemia time is believed to affect graft function by contributing to ischemia-reperfusion injury. Nominal data for the MITT are reported.
Measured: Within 14 days after OLT
Number of Patients With EAD in Case of Transplantation of Donor Organs Differing by the Duration (in Min) of Warm Ischemia
The number of EAD patients in case of transplantation of donor organs differing by the time of allograft removal from the donor and up to its reperfusion after engraftment (duration of warm ischemia) was assessed. In surgery, warm ischemia is the time a tissue, organ, or body part remains at body temperature after its blood supply has been reduced or cut off but before it is cooled or reconnected to a blood supply. In the transplant setting, this term is used to describe two physiologically distinct periods of ischaemia: (1) Ischemia during implantation, from removal of the organ from ice until reperfusion, and (2) Ischemia during organ retrieval, from the time of cross clamping (or of asystole in non-heart-beating donors), until cold perfusion is commenced. Nominal data for the MITT are reported.
Measured: Within 14 days after OLT
Number of Patients With EAD in Transplantation From Donors Having Additional Adverse Factors
The number of patients with early allograft dysfunction in transplantation from donors having additional adverse factors like infectious complication, death of the brain, hypotension, etc. was reported. The correlation between EAD and additional adverse factors are showed. Nominal data for the MITT are reported.
Measured: Within 14 days after OLT
Number of Patients With EAD in Transplantation With Regard to the Interval (in Hours) Between the Diagnosis of Brain Death and Removal of the Liver Graft From a Donor
The number of patients with allograft dysfunction in transplantation with regard to the interval between the diagnosis of brain death and removal of the liver graft from a donor (in the case of a brain-dead donor). This interval can last hours. Nominal data for the mITT are reported.
Measured: Within 14 days after OLT
Number of Patients With EAD in Transplant Recipients With Each of the Different Liver Disease Etiology
The number of patients with EAD in transplant recipients with liver diseases of different etiology (viral, alcoholic, autoimmune, etc.) was assessed.
Measured: Within 14 days after OLT
Incidence of Early Allograft Dysfunction (EAD) in Transplant Recipients With Liver Diseases of Different Etiology and With Different Baseline Characteristics
The incidence of early allograft dysfunction in transplant recipients with liver diseases of different etiology and with different baseline characteristics.
Herein the intent is reporting the number/percentage of subjects with EAD within 14 days after OLT, without distinction for disease etiology and baseline characteristics.
Measured: Within 14 days after OLT
The Number of Patients With EAD in Transplant Recipients With Liver Diseases (HBV and HCV Virus) and With Different Baseline Characteristics
The number of EAD patients in transplant recipients with liver diseases detected, and with different baseline characteristics was assessed. Herein HBV and HCV viral load at screening visit are reported.
Measured: Within 14 days after OLT
Incidence of Early Allograft Dysfunction in Transplant Recipients (Creatinine Clearance, ClCr)
The incidence of early allograft dysfunction in transplant recipients with different baseline characteristics. Herein Creatinine clearance at screening Day - 1 (mL/min). 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. the normal range of CrCl is 110 to 150mL/min in males and 100 to 130mL/min in females. Serum creatinine level for men with normal kidney function is approximately 0.6 to 1.2mg/dL and between 0.5 to 1.1 mg/dL for women. Creatine levels above the normal range indicate renal dysfunction.
Measured: Within 14 days after OLT
Incidence of Early Allograft Dysfunction in Transplant Recipients - Severity of Recipient's Liver Disease Through MELD Index
The incidence of early allograft dysfunction in transplant recipients with different score in scales of end-stage liver disease. The MELD score estimates a patient's chances of surviving their disease during the next three months. Practically, MELD is a reliable measure of mortality risk in patients with end-stage liver disease. It is used as a disease severity index to determine prognosis and help prioritize patients for organ allocation by estimating 3-month mortality risk. The MELD score ranges from 6 to 40 and is based on results from several lab tests. The higher the number, the more likely the subject is to receive a liver from a deceased donor when an organ becomes available.
MELD Score= 11.2 x In INR + 9.57 x In Creatinine (mg/dL) + 3.78 (if the patient had dialysis at least twice in the past week, the value for serum creatinine needs to be adjusted to 4.0) x In Bilirubine (mg/dL) + 6.43
Measured: Within 14 days after OLT
Number of Patients With EAD in Transplant Recipients Via Child-Turcotte-Pugh Score (CTP)
The incidence of early allograft dysfunction in transplant recipients with different allograft dysfunction based on CTP. This score assesses the severity of the disease, the risk of lethal outcome (during surgeries) and the prognosis in patients with cirrhosis. The CTP scoring system incorporates five parameters: serum bilirubin, serum albumin, prothrombin time, ascites, and grade of encephalopathy.
Each of them can score between 1 and 3. Based on the sum of the points from these five parameters, the patient is categorized into one of three CTP classes/grades: A, B, or C.
Score:
- 5-6 points - Grade A (least severe liver disease)
- 7-9 points - Grade B (moderately severe liver disease)
- 10-15 points - Grade C (most severe liver disease)
Measured: Within 14 days after OLT
Time to Liver Function Normalization of Liver Function Parameters
Time to normalization of liver function parameters (alanine aminotransferase, aspartate aminotransferase and bilirubin levels, gamma-glutamyltransferase, lactate dehydrogenase, etc.) after the OLT was assessed. Please note the upper limit of IC is not available due to insufficient number of participants with events.
Measured: Within 1 Year after OLT
Patient Survival Within 1 Year After OLT
Patient survival within 1 year after OLT was assessed. Please note the data are not available due to insufficient number of participants with events.
Measured: within 1 year after OLT
Mortality Within 1 Year After the OLT
Number of deaths within 1 year after the OLT was assessed.
Measured: Within 1 Year after OLT
The Incidence of Hyperacute, Acute and Chronic Liver Allograft Rejection .
Hyperacute or acute transplant rejection were determined by biopsy; chronic transplant rejection was defined by histological evaluation in both treatment groups.
Measured: Within 1 Year after OLT
Summary of Adverse Events up to 1 Year After the OLT
An Adverse Event (AE) was defined as any untoward medical occurrence in a patient or clinical investigation subject administered a medicinal product and which did not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavourable and unintended sign (including abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not related to the medicinal product.
Measured: up to 1 year after the OLT
