The company can now enroll patients, collect safety and effectiveness data, and operate under the FDA-approved trial protocol.
The trial will evaluate the updated OCS technology designed to keep donor hearts functioning outside the body for longer and under better conditions than cold storage. If successful, the study could support future regulatory filings and broader clinical use of the device, potentially increasing donor heart availability and improving transplant outcomes. TransMedics will now move forward with site activation and patient enrollment as outlined in the trial plan.

With over 650 patients planned, it is expected to become the largest heart preservation trial worldwide.
Part B will include DBD hearts not currently eligible for OCS perfusion, with the goal of expanding future clinical indications.
