Karius to Present Data on The Karius Test at ASM Microbe 2018

June 04, 2018

Announces Newly Expanded, Comprehensive Genomic Diagnostic for Infectious  Diseases
Covering 1,320 Pathogens with a Single Blood Test

REDWOOD CITY, Calif. — June 5, 2018 — Karius, a life sciences company focused on transforming infectious disease diagnostics with genomics, announced expanded bacterial and fungal coverage for its quantitative next-generation sequencing (NGS) plasma test for pathogen detection today. The Karius Test™ has been expanded by 70 microorganisms, now detecting 1,320 pathogens from one blood draw with next day results*. The test provides broad-based detection of clinically relevant pathogens, including more than 750 species of bacteria, over 100 DNA viruses and more than 300 fungi and molds. Scientists and clinicians will present data on the Karius Test performance and clinical applications in several sessions at the upcoming ASM Microbe 2018 conference in Atlanta.

Currently available to hospitals across the United States, the Karius Test reports the presence and abundance of microbial cfDNA. The test provides clinicians with a report of the amount of pathogen DNA found in a patient’s blood as compared to a reference range from asymptomatic adults, providing additional insights regarding the burden of infection given the clinical context. Clinicians are currently using the test to identify culture-negative or diagnostically-challenging infections in immunocompromised and critically-ill patients in various clinical scenarios, including sepsis1, endocarditis, febrile neutropenia, and patients who have received antibiotic pre-treatment2. In a study to be presented at the Karius Industry Showcase this week at ASM Microbe 2018, the Karius Test identified pathogens in sepsis patients more than three times as frequently as blood culture, and more often than blood culture and other microbiology tests combined3. The test also readily identifies deep infections that might otherwise require invasive biopsies, including invasive fungal infections4.

“We are helping infectious disease doctors and microbiologists identify some of their most challenging infections, particularly where current diagnostic methods are either limited, invasive or time-consuming,” said Dr. David Hong, Karius Vice President of Medical Affairs and Clinical Development, who will present study data at ASM on invasive fungal infections detected by the Karius Test in pediatric patients. “In my experience as a pediatric infectious disease physician, some of the most challenging clinical scenarios I encounter include invasive fungal infections in immunocompromised patients. Next-generation sequencing of cell-free plasma can rapidly and non-invasively identify fungal pathogens in immunocompromised pediatric patients, allowing for earlier, targeted treatment.”

Karius has the capability to readily expand the breadth of pathogen coverage through database enhancements as emerging pathogens are discovered and newly-relevant, high quality reference genomes become available. Clinicians can search for a specific pathogen or species using the Karius Pathogen List online.
