Prevencio and Seattle Children’s Research Institute Present Highly Accurate Data for First Time Artificial Intelligence-driven Multiple Protein Blood Test for Kawasaki Disease

Kawasaki Disease—a critical childhood disease—linked to COVID-19

KIRKLAND, Wash.--()--Prevencio, Inc. today announces presentation of highly accurate data on an Artificial Intelligence (AI)-driven blood test for Kawasaki disease (KD) at the Pediatric Academic Societies (PAS) International Sessions. The novel test, HART KD, was jointly developed with Seattle Children’s Research Institute and leveraged Prevencio’s AI-driven HART platform and expertise in developing cardiac blood tests.

For the first time, KD can be accurately diagnosed with easily measured, multiple proteins in children’s blood. A key differentiator is using an AI-driven algorithm, or weighting of each protein, to enhance the accuracy to an impressive 92% (AUC), as compared to nonspecific, single protein tests. This provides a long-needed, diagnostic blood test to distinguish KD from other infectious and inflammatory conditions.

“Kawasaki disease is the most common acquired heart disease in children and occurs mostly in children younger than 5 years old. Among the main presenting symptoms are persistent fever and rash. This makes diagnosis challenging as thousands of children with these symptoms present annually to U.S. emergency departments,” said Michael Portman, MD, director of pediatric cardiovascular research at Seattle Children’s and professor of pediatrics at the University of Washington School of Medicine. “Since COVID-19-associated Multisystem Inflammatory Syndrome in Children (MIS-C) and Kawasaki disease share similar presenting symptoms, timely and accurate diagnosis of Kawasaki disease is even more critical.”

Without early treatment, there is a 25%-30% risk of heart artery dilation and aneurysms that may ultimately result in heart attacks, congestive heart failure, sudden death, and need for lifelong therapy.

Portman added, “To date, there is no specific diagnostic test for Kawasaki disease. We are excited with the robust 92% accuracy of HART KD and appreciate our collaboration with Prevencio to address this critical, unmet medical need.”

Incidence rates of KD in the U.S. are 19 to 25 cases per 100,000 children under age five and rising. Predictive models estimate that by 2030, one in every 1,600 American adults will have been affected by the disease. Prevalence rates are even higher among children in Asia. Japan has the highest incidence rate, with more than 16,000 new cases per year. One in every 60 boys and one in every 75 girls in Japan will develop KD during childhood.

Rhonda Rhyne, Prevencio’s Chief Executive Officer, added, “We are pleased to collaborate with Seattle Children’s Research Institute, one of the nation’s top five pediatric research centers, and are excited to expand use of our AI Hart platform to Kawasaki disease. It is rewarding to contribute to diagnosing this life-threatening childhood disease.”

Prevencio is in commercialization discussions with protein-measuring platform companies for partnerships and licensing to offer HART KD for children suspected of Kawasaki disease.

About Prevencio HART Tests:

Powered by AI, Prevencio is revolutionizing blood tests for cardiovascular disease and custom diagnostics. Employing this novel approach, the company has developed seven blood tests that significantly improve diagnoses for a variety of heart and blood vessel-related complications.

Our three lead tests include:

  1. HART CADhs™ – obstructive coronary artery disease diagnosis
  2. HART CVE™ – 1-year risk of heart attack, stroke or cardiac death
  3. HART KD™ – Kawasaki disease diagnosis

HART test results have been peer-reviewed presented 21 times, including at leading cardiovascular meetings—(European Society of Cardiology Congress – 2016, 2018; American College of Cardiology Scientific Sessions – 2017, 2018, 2019, 2020; American Heart Association Scientific Sessions – 2017, 2018, 2019; American Diabetes Association Scientific Sessions – 2018, 2019; and Pediatric Academic Societies International Sessions – 2021) and published in top-tier journals—(Journal of American College of Cardiology – Mar 2017; American Journal of Cardiology – July 2017; Clinical Cardiology – June 2018; Open Heart – November 2018, May 2019; Jan 2019; Biomarkers in Medicine – June 2020; Journal of American Heart Association – Aug 2020).
