Dr. Hong joined Karius after 14 years at Stanford University, where he was Clinical Assistant Professor of Pediatric Infectious Diseases. He also served as chief of pediatric infectious diseases at the Stanford-affiliated Santa Clara Valley Medical Center. His prior studies in respiratory virus infections in children focused on host–pathogen interactions and novel adjuvants for respiratory virus vaccines. Read his full bio.
Interview with David Hong of Karius
Q: What need is Karius addressing?
Q: What are the products and/or services Karius offers/develops to address this need? What makes Karius unique?
A: The Karius(R) Test is a single blood test that can identify over 1,000 pathogens including DNA viruses, bacteria, fungi, molds, and protozoa. It can detect both bloodstream and deep-seated infections by identifying and quantifying cell-free pathogen DNA present in the blood which is derived from dead and dying organisms from throughout the body. Because of the non-invasive nature of the Karius Test, we think of it as a liquid biopsy for infectious disease. This approach can rapidly and accurately identify pathogens even in challenging infectious syndromes such as sepsis, culture-negative endocarditis, invasive fungal infections, and complicated pneumonia.
Q: What is your role at Karius and what excites you about your work?
A: I oversee both the Clinical Development and Medical Affairs groups at Karius. On the Clinical Development side, we have a strong team that designs and executes our clinical studies in partnership with great collaborators around the country. On the Medical Affairs team, we provide pre- and post-testing clinical consultations to clinicians and meet with doctors to provide information and clinical data about the test.
Both roles are incredibly exciting and satisfying because I get to interact with a diverse range of clinicians and lab directors who are interested in applying the Karius Test to clinical care. Nothing is more exciting than to get on the phone with a physician and hear how the Karius Test result clinched a diagnosis, changed management, and impacted patient care.
I get a front row seat witnessing the future of infectious disease management.
Q: When thinking about Karius and the domain Karius is working in, what are some of the recent breakthroughs that are propelling the field forward and how will they impact healthcare?
A: The application of genomics has transformed the fields of heritable diseases, prenatal care, and oncology by unlocking previously inaccessible information. We believe that the same is true for the field of infectious diseases.
With improvements in sequencing technology, computing power, and data analytics, we now have tools to unlock microbial information to help clinicians more effectively treat their patients. Ultimately I believe the combination of host genomic data and microbial data will give us a much fuller picture of how human-microbe interactions contribute to health and disease.
Q: What are the short-term challenges that Karius and its peers are facing?
A: In the short-term, the major challenge is convincing physicians that metagenomic sequencing approaches for infectious disease diagnostics are not just research tools or tests of last resort. We’re working on the studies to show that the Karius Test can positively impact patient outcomes and be a cost-effective approach to help diagnose some of the most challenging infections, particularly when applied as an early diagnostic tool.
Q: Is there anything else you would like to share with the PMWC audience?
A: We are only beginning to understand how metagenomic sequencing approaches like the Karius Test will improve patient care. At the recent American Society of Microbiology meeting, it was great to see how many people in the infectious disease and microbiology community are really pushing to advance the field. Just a year ago, there were only a few of us talking about sequencing-based infectious disease diagnostic tests. This year there were multiple sessions dedicated to these novel diagnostic approaches.
Our collaborators will be presenting a number of abstracts at IDWeek this October in San Francisco that describe how the Karius Test performs across a diverse array of patient types including invasive fungal infections, fever and neutropenia, endocarditis, and complicated pneumonia. Please come find us at these presentations or at our booth to say hi and learn more about what we’re doing.
The Precision Medicine World Conference (PMWC), in its 17th installment, will take place in the Santa Clara Convention Center (Silicon Valley) on January 21-24, 2020. The program will traverse innovative technologies, thriving initiatives, and clinical case studies that enable the translation of precision medicine into direct improvements in health care. Conference attendees will have an opportunity to learn first-hand about the latest developments and advancements in precision medicine and cutting-edge new strategies and solutions that are changing how patients are treated.
