• Median TTR for VKAs in ARIES-HM3 trial was only 56%, indicating suboptimal anticoagulation management

Medical Research Analyst

The publication in the Journal of Cardiac Failure provides valuable insights into the challenges of anticoagulation therapy for LVAD patients. The study's findings, showing a 47% reduction in bleeding risk for patients with above-median TTR, underscore the critical importance of maintaining stable anticoagulation levels. This data strongly supports the potential benefits of tecarfarin, which could offer more consistent anticoagulation than warfarin.

The inverse relationship between TTR and bleeding events, coupled with the prevalence of sub-therapeutic INRs, suggests that current anticoagulation strategies are suboptimal. Tecarfarin's unique metabolic pathway could address these issues, potentially reducing complications and improving patient outcomes. However, it's important to note that while promising, tecarfarin still requires further clinical validation in LVAD patients specifically.

Financial Analyst

This publication represents a significant milestone for Cadrenal Therapeutics (NASDAQ: CVKD), potentially boosting investor confidence in tecarfarin's market potential. The LVAD patient population, while niche, represents a high-value market due to the critical nature of anticoagulation therapy and the current limitations of warfarin.

The endorsement from Dr. Mandeep Mehra, a respected figure in the field, adds credibility to tecarfarin's potential. However, investors should note that Cadrenal is still in the development stage and regulatory approval is not guaranteed. The company's focus on this unmet need could position it well in the $11 billion global anticoagulants market, but it will face competition from both established and emerging therapies. Financial performance will depend on successful clinical trials and eventual market adoption.

PONTE VEDRA, Fla., Aug. 20, 2024 /PRNewswire/ -- Cadrenal Therapeutics, Inc., (Nasdaq: CVKD), a biopharmaceutical company developing tecarfarin, a late-stage, next-generation VKA oral and reversible anticoagulant (blood thinner) designed to prevent heart attacks, strokes, and deaths due to blood clots in patients with implanted cardiac devices or rare cardiovascular conditions, today highlighted a manuscript that was recently peer-reviewed and published in the Journal of Cardiac Failure evaluating the relationship between time in therapeutic range, or TTR, management quality and LVAD patient clinical outcomes. These findings focus on the potential role of investigating new VKA agents beyond warfarin in improving clinical outcomes in LVAD patients.

In the manuscript co-authored by Mandeep R. Mehra, MD, MSc, FRCP, Brigham and Women's Hospital Heart and Vascular Center, Center for Advanced Heart Disease, titled "Antithrombotic Strategies with Left Ventricular Devices," the findings conclude that although the current generation of LVAD pumps has largely overcome hemocompatibility-related adverse events there is a continuing need to evolve the anticoagulant therapy to avoid persistent gastrointestinal bleeding, which leads to frequent hospital admissions, procedures, blood transfusions, decreased quality of life and increased cost of care.¹ 

Dr. Mandeep Mehra, who chaired the ARIES-HM3 study, commented, "Tecarfarin could potentially be an important therapy for patients with LVADs who all require chronic anticoagulation since it does not get affected by drug-drug interactions or changes in kidney function like warfarin and deserves further study."

A secondary analysis of the ARIES-HM3 trial, sponsored by Abbott, evaluated the relationship between VKA management quality and clinical outcomes, wherein a median TTR for VKAs of 56% was achieved. This analysis found an inverse relationship between TTR and bleeding events, with a 47% reduction in bleeding risk for patients with a TTR above the median. Lower TTRs were associated with threefold more sub-therapeutic INRs than supra-therapeutic INRs, with no clear correlation between higher INRs and bleeding events.

"These findings provide us with increased confidence that tecarfarin has the potential to address the LVAD patients' critical unmet anticoagulation needs more effectively," said Quang X. Pham, Chairman and Chief Executive Officer of Cadrenal Therapeutics. "We are excited to work with the LVAD community to potentially bring our next-generation VKA to patients."

About Tecarfarin
Tecarfarin is the only oral anticoagulant in development worldwide for patients with implanted cardiac devices and other rare cardiovascular conditions. It has been uniquely designed to overcome many of the challenges patients experience with warfarin. Tecarfarin is metabolized using carboxyl esterase rather than the cytochrome P450 system, which allows the drug to avoid interactions with many other commonly used medications and may offer more stable anticoagulation, including those patients with renal dysfunction, which is common in LVAD patients. In a Phase II study with 66 patients with atrial fibrillation switched from warfarin to tecarfarin, the mean interpolated TTR was 71.4% within three weeks, with minimal time spent in extreme INR ranges (<1.5 and >4.0). If approved, tecarfarin has the potential to be the only on-label drug for LVAD patients in the U.S.

In addition, tecarfarin may prove valuable for other patients where warfarin is not providing recommended anticoagulation because of genetic warfarin resistance or renal impairment making warfarin metabolism difficult. These include individuals with end-stage kidney disease and atrial fibrillation or those with mechanical heart valves and hard-to-control International Normalized Ratio, which measures how long it takes the blood to clot.

On August 6, 2024, Cadrenal Therapeutics announced that it had been in discussions with Abbott about Cadrenal's planned pivotal study of tecarfarin in patients with recently implanted LVADs. LVAD patients require lifelong anticoagulation to protect against thromboembolic events. The only LVAD available in the U.S. is Abbott's HeartMate 3^TM. 

On April 9, 2024, Cadrenal Therapeutics announced that the U.S. Food and Drug Administration (FDA) had granted tecarfarin Orphan Drug Designation for the prevention of thromboembolism and thrombosis in patients with an implanted mechanical circulatory support device, which includes the LVAD.
