TransMedics Announces Positive Top Line Results From the U.S. Randomized OCS DCD Heart Trial

Nov, 4 2021 at 7:00 AM EDT

ANDOVER, Mass., Nov. 4, 2021 /PRNewswire/ -- TransMedics Group, Inc. ("TransMedics") (Nasdaq: TMDX), a medical technology company that is transforming organ transplant therapy for patients with end-stage lung, heart, and liver failure, today announced positive topline results from its OCS donors after circulatory death (DCD) Heart Trial.

The OCS DCD Heart Trial was designed as the first and only randomized trial to compare post-transplant clinical outcomes between hearts transplanted from DCD donors that were resuscitated and assessed on OCS Heart System and hearts transplanted from donors after brain death (DBD) that were preserved using the current standard of cold storage in the U.S. The primary goal was to assess the effectiveness and safety of OCS Heart technology to expand the heart donor pool to include DCD donors. Heart transplant candidates were randomized 3:1 into two groups: DCD Heart Possible (DCD) or DBD cold stored hearts (Control). The trial protocol compared the post-transplant outcomes from recipients of DCD hearts preserved on OCS (DCD) to all those who received standard criteria DBD hearts preserved with cold storage (DBD Control).

The OCS DCD Heart trial achieved its primary clinical objectives by meeting the primary effectiveness endpoint of 6 months patient survival post-transplant which was 95% for OCS DCD arm vs. 89% for DBD Control arm. Even when the outcomes were adjusted for all risk factors between the two groups the results were 94% for OCS and 90% for Control (non-inferiority p<0.0001). Of 101 DCD donor hearts that were perfused and assessed on OCS Heart technology, 90 were successfully transplanted resulting in a utilization rate of 89%. Long-term followup is ongoing and the final results will be presented at the upcoming Scientific Meeting of the International Society for Heart and Lung Transplantion in April 2022.

The OCS Heart System was approved by the U.S. Food and Drug Administration (FDA) for its DBD heart indication in September 2021. These OCS DCD Heart trial results will be submitted shortly to FDA in a PMA supplement to support the approval for the OCS DCD heart indication.

"The OCS DCD Heart Trial provides objective randomized evidence showing high utilization and excellent short-term clinical outcomes using hearts that historically were never considered for transplants in the U.S.," said Dr. Jacob Schroder, surgical director of heart transplantation at Duke University Medical Center and the principal investigator for the OCS DCD Heart Trial. "The more widespread use of DCD hearts for transplantation is the biggest thing to happen since the beginning of heart transplantation!"

"These results are tremendously exciting and confirm our belief that the OCS Heart System is a transformative technology that allows us to safely utilize donor organs that were previously never considered," said Dr. David D'Alessandro, surgical director of heart transplantation at Massachusetts General Hospital and the co-principal investigator for the OCS DCD Heart Trial. "We now have a unique technology which will allow us to offer this life saving therapy to more patients than ever before."

"These clinical results are transformative to the field of heart tranplantation. The trial met and exceeded the very high bar of comparing transplant clinical outcomes of OCS DCD heart to standard criteria DBD heart in the U.S., which are known to be the best in the world," said Waleed Hassanein, MD, President and Chief Executive Officer. "This will have a far reaching positive impact on increasing access to life-saving heart transplants to patients in need. We are very grateful for all the donor families, trial investigators, their teams, and institutions for completing this seminal trial in heart transplantation."
