A Phase 1/2, First-in-Human Safety and Proof-of-Concept Study to Evaluate EGEN-5784 Porcine Liver (Drug Product) in Combination With the Metra® Extra-Corporeal Liver Cross-Circulation System in Participants With Acute-on-Chronic Liver Failure

Summary

This is a Phase 1/2, first-in-human (FIH) safety, proof-of-concept, two-part study of the genetically-engineered EGEN-5784 liver in combination with the metra® extra-corporeal liver cross-circulation (ELC) system in participants with Grade 2 to Grade 3 acute-on-chronic liver failure (ACLF) and hepatic encephalopathy Grade 1-3. The metra® device has been modified for the purposes of cross-circulation with an extra-corporeal porcine liver. The EGEN-5784 liver and metra® ELC system are designed to support liver function during the treatment period

Interventions

• Device
  metra® Extracorporeal Liver Cross-Circulation (ELC) system (OrganOx)

  Perfusion circuit/device enabling extracorporeal cross-circulation between the participant and the EGEN-5784 porcine liver. Planned support up to 72 h in Part 1 and up to 120 h in Part 2 if no safety/stopping criteria are met, with ICU-level monitoring and protocol-defined operating parameters.

• Biological
  EGEN-5784 (genetically engineered porcine liver)

  Viable porcine liver from a genetically engineered donor (EGEN-5784) used for temporary extracorporeal cross-circulation support. The liver is not implanted; it is perfused in a closed circuit with the participant under continuous monitoring and predefined stopping rules per protocol.
