Exhibit 99.1

Cadrenal Therapeutics to File for FDA Rare Pediatric Disease Designation for Tecarfarin in Kawasaki Disease

Company to present Phase 3-ready pipeline, 12-LOX platform, and pediatric rare-disease expansion to global pharmaceutical partners at the 2026 BIO International Convention in San Diego

Kawasaki disease is the leading cause of acquired heart disease in children in developed nations. Patients are at risk of forming blood clots in coronary arteries and may require lifelong treatment

If the designation is granted and tecarfarin is approved for this indication, Cadrenal would be eligible to receive a Priority Review Voucher—recent open-market valuations for these vouchers have reached into the ~$200 million range

PONTE VEDRA, FL — June 18, 2026 — Cadrenal Therapeutics, Inc. (Nasdaq: CVKD), a biopharmaceutical company advancing late-stage novel therapies for life-threatening immune and thrombotic conditions, today announced plans to submit a Rare Pediatric Disease Designation (RPDD) request to the U.S. Food and Drug Administration (FDA) for tecarfarin as a treatment for pediatric patients with Kawasaki disease (KD) who develop coronary artery aneurysms (CAAs) and require chronic oral anticoagulation.

The announcement comes ahead of the BIO International Convention, June 22–25, 2026, in San Diego, California. Cadrenal’s executive leadership team will highlight this rare pediatric initiative and its Phase 3-ready CAD-1005 platform during one-on-one partnering meetings with global and regional pharmaceutical companies.

KD is an acute inflammatory illness and the leading cause of acquired heart disease in children in developed nations. Up to 25% of untreated children with KD develop enlarged coronary arteries or CAAs. Patients with large CAAs are at risk for forming blood clots in those blood vessels – with a continuing lifelong risk for subsequent heart attacks and sudden cardiac death - and require chronic, precise anticoagulation therapy to reduce their higher risk of clot formation.

Tecarfarin is a novel, next-generation Vitamin K antagonist (VKA) that offers a number of potential advantages over warfarin, the current standard VKA in clinical use. Specifically, tecarfarin is designed to overcome limitations of warfarin metabolism and potentially provide more reliable and more consistent anticoagulation than might be possible with warfarin.

“Children with large or giant aneurysms due to KD represent an important underserved orphan population,” said Quang X. Pham, Chief Executive Officer of Cadrenal Therapeutics. “The current standard of care – warfarin - is notoriously unstable in children because of dietary variations, concurrent medications, and genetic differences in liver metabolism. Tecarfarin is metabolized in a completely different way than warfarin, and is being developed to offer a highly stable, predictable alternative. We believe tecarfarin can potentially improve time in therapeutic range for these children, thereby lowering their risk for both catastrophic blood clots and dangerous bleeding events.”

The FDA’s RPDD program targets serious or life-threatening diseases that primarily affect fewer than 200,000 people in the United States from birth through age 18. If the FDA grants the designation and tecarfarin is subsequently approved for this indication, Cadrenal would be eligible to receive a Priority Review Voucher (PRV). These transferable vouchers can be used to accelerate the FDA review of a future drug or sold to another pharmaceutical manufacturer. Following Congress’s extension of the pediatric PRV program through September 30, 2029, recent open-market valuations for these vouchers have reached record highs, with recent sales ranging from $180 million to $205 million.

At the upcoming BIO International Convention, Cadrenal will present a dual-track portfolio strategy designed to maximize value for potential partners:

“Our presence at BIO 2026 centers on executing capital-efficient development strategies,” added Mr. Pham. “If we are successful in advancing tecarfarin toward a RPDD, we will create a high-value, de-risked regulatory pathway that aligns with regional partners’ portfolio needs while directing our core internal resources toward our blockbuster CAD-1005 critical care franchise.”
