E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the rate of composite efficacy failure (Biopsy Proven Acute Rejection (BPAR), graft loss or death) with CFZ533 regimens compared to TAC Control at Month 12 post-transplantation. |
|
E.2.2 | Secondary objectives of the trial |
-To evaluate the renal function with CFZ533 regimens compared to TAC Control at Month 12 post-transplantation. -To evaluate eGFR and change in eGFR to Month 12 and Month 24 post-transplantation. -To evaluate whether CFZ533 regimens have lower incidence rates over 12 and 24 months post-transplantation compared to TAC control arm for the following events: - BPAR - tBPAR - AR - Antibody mediated (humoral) rejection - Graft Loss - Death -To assess the safety and tolerability of CFZ533 regimens compared to TAC control at Month 12 and Month 24. -To assess the pharmacokinetics of multiple doses of CFZ533 over the 12-month and 24-month treatment and explore the dose-exposure relationship. -Additional secondary objectives as per protocol |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Screening period up to liver transplantation: -Male or female subjects 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 (based on laboratory values, using the United Network for Organ Sharing (UNOS) MELD calculator: https://unos.org/resources/allocation-calculators/). -Transplantation to occur within defined screening period following informed consent signature.

|
E.4 | Principal exclusion criteria |
Screening period up to liver transplantation: -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. -Recipients negative for Epstein Barr virus (EBV) test. -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 is evidence of local recurrence or metastases. -Hepatocellular carcinoma that does 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 donors HIV positive. -Recipients with donors HBsAg positive. -Recipients who are 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
At randomization: -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. -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 (after anti-TB treatment, patients with history of latent TB may become eligible according to national guidelines). -Recipients who are on renal replacement therapy at randomization. -Any episode of acute rejection or suspected rejection prior to randomization. -HCC participants whose explanted liver graft pathology report shows i) pTNM stage beyond T2N0M0, ii) presence of mixed carcinoma, iii) microvascular invasion despite pTNM stage -Participants with body weight < 30 kg or > 180 kg. |
