Eligibility Criteria
Inclusion
- Key
- Screening period up to liver transplantation:
- Written informed consent obtained before any assessment.
- Male or female patients between 18 to 70 years of age.
- Recipients of a primary liver transplant from a deceased donor.
- Up to date vaccination as per local immunization schedules.
- Recipients tested negative for HIV.
- MELD score ≤ 30.
- Transplantation to occur within defined screening period following informed consent signature.
- At randomization (Day 8 +/- 2):
- Recipients with no active HCV and HBV replication.
- Allograft is functioning at an acceptable level by the time of randomization as defined by AST, ALT and Alkaline Phosphatase levels ≤ 5 times ULN and Total Bilirubin ≤ 2 times ULN.
- Renal function (eGFR, MDRD-4 formula) ≥ 30 mL/min/1.73 m2 based on most recent post-transplant value prior to randomization.
- Recipients who have been initiated on an immunosuppressive regimen that contains TAC, mycophenolate mofetil (MMF) and corticosteroids (CS) as per protocol.
- Key
Exclusion
- Screening period up to liver transplantation:
- Use of other investigational drugs at screening within 30 days or 5 half-lives of screening.
- Recipients of multiple solid organ or islet cell transplants, or recipients that have previously received a tissue transplant, or a combined liver-kidney transplant.
- Recipients of a liver from a donor after cardiac death (DCD), from a living donor, or of a split liver.
- Recipient who tested negative for Epstein Barr virus (EBV) within 28 days prior to baseline visit.
- Recipients receiving an ABO incompatible allograft.
- History of malignancy of any organ system (except hepatocellular carcinoma (HCC) or localized basal cell carcinoma of the skin), treated or untreated, within the past 5 years, regardless of whether there was evidence of local recurrence or metastases.
- Hepatocellular carcinoma that did not fulfill Milan criteria (1 nodule ≤ 5 cm, 2-3 nodules all ≤ 3 cm, without evidence of metastatic disease or vascular invasion) at the time of transplantation.
- Recipients transplanted for acute liver failure (does not apply to acute on chronic liver failure).
- Any use of antibody induction therapy, or use of any immunosuppressive medications (or other medications prohibited by the protocol).
- Patients who have received a live vaccine within four weeks prior to transplantation.
- Recipients with HIV positive donor.
- Recipients with donors HBsAg positive.
- Recipients who were HCV antibody-positive without documented sustained viral response (SVR) at 12 weeks after finishing anti HCV treatment (e.g., direct-acting antivirals).
- Recipients with HCV RNA-positive donors.
- Recipients with donors with macrovesicular steatosis \> 30%.
- Pregnant or nursing (lactating) women.
- At randomization (Day 8 +/- 2):
- Any post-transplant history of thrombosis, occlusion or stent placement in any hepatic arteries, hepatic veins, portal vein or inferior vena cava at any time during the run-in period prior to randomization. Absence of any graft vascular thrombosis or occlusion (by diagnostic method used at the site to assess vascular patency) must be confirmed by imaging prior to randomization.
- Recipients with platelet count \< 50,000/mm3.
- Recipients with an absolute neutrophil count of \< 1,000/mm³ or white blood cell count of \< 2,000/mm³.
- Recipients with clinically significant systemic infection requiring use of intravenous (IV) antibiotics.
- Evidence of active tuberculosis (TB) infection.
- Recipients who are in a critical care setting at the time of randomization requiring life support measures such as mechanical ventilation, dialysis, requirement of vasopressor agents.
- Recipients who were on renal replacement therapy at randomization.
- Any episode of acute rejection or suspected rejection prior to randomization.
- HCC patients whose explanted liver graft pathology report shows (i) pathologic Tumor-Node-Metastasis (pTNM) stage beyond T2N0M0, (ii) presence of mixed carcinoma, (iii) microvascular invasion despite pTNM stage.
- Patients with body weight \< 30 kg or \> 180 kg.
