The U.S. FDA has granted premarket approval for Transmedics Group Inc.’s OCS heart system for use with organs from donors after circulatory death (DCD). The approval expands on a prior FDA approval of the device for use with organs from donors after brain death in September 2021. Andover, Mass.-based Transmedics said its system can now be used for ex vivo reanimation, functional monitoring, and beating-heart preservation of donation-after-circulatory-death hearts.
In a move that will substantially expand the number of livers available for transplantation, the FDA granted premarket approval to Organox Ltd.’s Metra normothermic machine perfusion device for both donors after brain death (DBD) and donors after circulatory death (DCD). The approval allows preservation of organs by Metra for up to 12 hours.
The FDA advisory hearing for the Transmedics Organ Care System (OCS) resulted in a unanimous vote in favor of the OCS’s safety and efficacy numbers, although there will be a considerable post-approval study requirement. The company was able to overcome a number of problems with the pivotal study that might otherwise have tanked the application, such as the lack of blinding of transplant surgeons, which the FDA said could have biased the determination of whether a liver was acceptable for transplant.
The shortage of hearts for transplant is a matter of record for both cardiologists and patients, a problem that Transmedics Inc. proposed to solve with its Organ Care System (OCS). Despite several significant issues associated with the pivotal clinical study for the OCS, Transmedics snared a 12-5 vote that the benefits of the system outweigh the risks, an outcome that may bring at least some relief for heart transplant patients by mid-year if analyst expectations are on target.
Transmedics Group Inc. reported a proposed public offering of $60 million of its shares of common stock (NASDAQ:TMDX). The Andover, Mass.-based company expects to grant underwriters a 30-day purchase option for additional shares of its common stock up to 15% of the number of shares sold in the offering. J.P. Morgan and Morgan Stanley are jointly managing the proposed offering with Canaccord Genuity acting as lead manager.
