The study took place at 15 US liver transplant centers and patients were enrolled between January 2021 and May 2023. Central assessment of complications and cholangiograms for nonanastomotic biliary strictures (NAS) was blinded to treatment arm. Participants included 219 recipients of extended-criteria donor livers after brain death (DBD) and after circulatory death (DCD) who were randomized 1:1 to HOPE after static cold storage (SCS) (n\u2009=\u2009109) or SCS only (n\u2009=\u2009110). Randomization was performed after liver inspection and acceptance for transplant. Data were analyzed from December 2024 to July 2025.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Intervention<\/jats:title>\n                    <jats:p>After SCS and transport, livers underwent portal-venous HOPE until implant, using the VitaSmart HOPE System.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Main Outcomes and Measures<\/jats:title>\n                    <jats:p>The primary efficacy end point was early allograft dysfunction (EAD).

EAD incidence was 20.2% (22 of 109) with HOPE vs 37.3% (41 of 110) with SCS (rate difference,  \u221217.1%; 95% CI, \u221227.2 to  \u22127.0; noninferiority\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&amp;amp;lt;\u2009.001; superiority\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u2009.005).
