This multicentric randomized controlled trial concerns adult patients undergoing whole liver transplantation in any of the 8 participating centers in France, who will receive an ECD liver graft from a brain-dead donor. After providing written informed consent prior to the performance of any study specific procedure, the recruited patients will be randomized either in the experimental group (HOPE group) or in the control group. In the HOPE group, ECD liver grafts will undergo a hypothermic oxygenated perfusion (HOPE) via the portal vein for a period of 1 to 4 hours (minimum 1 hour) after the "back-table" phase (graft preparation), in parallel with the recipient hepatectomy, using the CE-certified Liver Assist® perfusion pump/device (Organ Assist®, the Netherlands) with Machine Perfusion Solution (Belzer-MPS, CE-certified). The control group will consist of a classic static cold (4°C) storage with Institute George Lopez (IGL-1)® solution from graft harvesting until liver transplantation, which is the gold standard procedure in liver transplantation. The primary endpoint will be early allograft dysfunction (EAD) according to Olthoff's criteria, which will be compared with the Model of Early Allograft Function score (MEAF score) and the Liver Graft Assessment Following Transplantation risk factor (L-GrAFT). According to the primary endpoint, a sample size of 133 patients per randomized group (266 in total) is needed. The duration of the inclusion period is expected to be 36 months with a 1-year follow-up for each patient. The potential impacts of the study are expected on 3 levels: (1) for the patient, decreased postoperative morbidity and mortality of liver transplantation with ECD donors; (2) for the French liver transplantation community, familiarization with liver machine perfusion, and (3) economically, decreased costs of liver transplantation (health economic analysis included in the study).
