Cadrenal Therapeutics, Inc. announced that the United States Food and Drug Administration (FDA) has granted tecarfarin Orphan Drug Designation (ODD) for the prevention of thromboembolism and thrombosis in patients with an implanted mechanical circulatory support device (left ventricular assist device (LVAD), right ventricular assist device (RVAD), collectively known as ventricular assist devices (VADs), biventricular assist device, and total artificial heart). The FDA?s ODD program provides incentives to sponsor organizations for the development of innovative treatments for rare diseases that affect fewer than 200,000 people in the U.S. Since its adoption in 1983, the Orphan Drug Act has helped countless individuals living with these conditions gain access to life-enhancing and life-saving therapies. ODD also provides certain benefits to drug developers, including assistance in the drug development process, tax credits for certain clinical research, and a waiver of the New Drug Application user fee.

The designation is made to promote safe and efficacious products for the treatment of rare conditions. All patients with VADs require chronic anticoagulation to prevent the formation of thrombus (clot) which can cause the device to fail or can result in a clot breaking off (embolizing), resulting in a stroke or other vascular catastrophe. The current market-leading direct oral anticoagulants (DOACs), such as Eliquis, are not indicated for patients with VADs due to a lack of evidence of benefit.

Moreover, a recent study revealed that the level of anticoagulation achieved with warfarin, the only currently available Vitamin K Antagonist (VKA), is maintained in the target range only 56% of the time which has been shown to increase the risk of clotting and bleeding complications.
