“The PROTECT trial showed superior clinical results in the short and medium term and a higher number of donor livers used for transplantation,” said Dr. James F. Markmann, chief of the transplant surgery division at Massachusetts General Hospital and senior author of the manuscript. “We concluded that the advent of portable extracorporeal and extracorporeal donor liver perfusion offers for the first time a practical and effective approach to clinically assess and improve donor liver function, thereby improving the safety of transplantation, expanding the pool of liver donors and reducing the waiting list – This is a game-changer in the area of ​​liver transplantation. “

“We believe that these superior clinical results represent a revolutionary step for liver transplantation,” said Walid Hassanein, MD, President and CEO. “This publication is further evidence that the OCS Liver System, along with our OCS Lung and OCS Heart Systems, will dramatically improve patient outcomes and expand the pool of eligible donors, thereby saving more lives. “

About the OCS ™ Liver PROTECT Trial

The OCS ™ Liver PROTECT trial was a pivotal, two-arm, multicenter, prospective, randomized, controlled trial to evaluate the efficacy and safety of the OCS ™ Liver for preserving and evaluating donor livers for transplantation. The trial enrolled 300 patients, including 153 patients randomized for transplantation using the OCS ™ Liver and 147 patients randomized to the control group, who used cold storage methods. Registration ended in October 2019 with transplants performed in a network of 20 major liver transplant centers in the United States

The primary endpoint of study efficacy was the incidence of ADE during the first 7 days after transplant procedures. The primary safety endpoint of the study was the mean number of serious adverse events (SAEs) related to liver transplantation per patient measured over the 30 days following transplant procedures. The study also measured the rate of DCD and DBD donor utilization, the incidence of ischemic biliary cholangiopathy, and other clinical parameters throughout the first year after liver transplantation.

The results of the study demonstrated that the primary efficacy endpoint was achieved by a significant decrease in ADE (27 out of 150 [18%] against 44 out of 141 [31%]; P = .01) and that the preserved livers from the OCS ™ liver showed a significant reduction in histopathologic evidence of ischemia-reperfusion injury after reperfusion (eg, less moderate to severe lobular inflammation: 9 of 150 [6%] for OCS ™ Liver vs 18 out of 141 [13%] for ischemic cold storage (ICS); p = 0.004). The OCS ™ Liver resulted in significantly higher utilization of donor livers after cardiac death (28 of 55 [51%] for OCS ™ liver vs 13 of 51 [26%] for the SCI; p = .007). OCS ™ Liver was also associated with a significant reduction in the incidence of CSI 6 months (1.3% vs. 8.5%; P = 0.02) and 12 months (2.6% vs. 9.9 %; P = 0.02) after the transplant.
