Karius Secures BARDA Contract to Expand Agnostic Detection of Pathogens

 a leader in genomic diagnostics for infectious diseases, announced today that the Karius Test® has been granted designation as a Breakthrough Device from The Center for Devices and Radiological Health (CDRH) of the US Food and Drug Administration (FDA), for use in the diagnosis and management of immunocompromised patients with suspected lung infections including lower respiratory infection and pneumonia.

“The Karius Test is commercially available nationwide as a laboratory developed test. We are seeking FDA marketing authorization of the Karius Test for lung infections in immunocompromised patients because improved diagnostic tests are urgently needed for these patients,” stated Brad Perkins, M.D., Chief Medical Oﬃcer of Karius. “As noted in the 

American Thoracic Society (ATS) Workshop Report for Immunocompromised Host Pneumonia: Deﬁnitions and Diagnostic Criteria

 lung infections have high morbidity and mortality in immunocompromised patients, which is why advances in technologies like metagenomic sequencing used for the Karius Test are vital in improving the diagnosis and treatment of these patients.”

The 

 is a voluntary program for certain medical devices and device-led combination products that provide for more eﬀective treatment or diagnosis of a life-threatening or irreversibly debilitating disease or condition. This program is designed to expedite the development and review of these innovative medical devices.

Clinical data that support the use of the Karius Test in pneumonia for immunocompromised patients includes the results of the 

 study, where results showed that the Karius Test increased the relative yield for detection of a probable cause for pneumonia by 40%.

 Additionally, the Karius Test identiﬁed clinically relevant non-pneumonia infections in 39% of subjects.

 These additional data highlight the ATS Workshop Report observation that "the existing clinical deﬁnition of pneumonia is syndromic and lacks speciﬁcity," 1 and support the value of approaches that are agnostic to both the pathogen and the site of infection like the Karius Test.

“Recent data from several trials indicate that the Karius Test oﬀers a speedy, accurate, and sensitive diagnosis of infectious causes of pneumonia and related infections in immunocompromised patients. As such, it represents a major advance in the care of patients with hematologic cancers and those undergoing stem cell transplantation,” said Norman E. Sharpless, MD; former Director of the National Cancer Institute and Acting Commissioner of the Food and Drug Administration, and member of the Karius board.

New data from the PICKUP study on the cost-eﬀectiveness of the Karius Test will be presented at the 

American Thoracic Society Annual Meeting 2024

 International Conference.

Karius Raises $100M Co-Led by Khosla Ventures, 5AM Ventures and Gilde Healthcare, to Expand Access to Advanced Genomic Diagnostics in Infectious Disease, Addressing Antimicrobial Resistance Crisis

 - A pivotal multi-center study published in Clinical Infectious Diseases demonstrates the effectiveness of the Karius Test®, a blood test based on metagenomics next generation sequencing of microbial cell-free DNA, by increasing the identification of pathogens causing pneumonia in immunocompromised patients by 40% (20/52) when combined with usual care diagnostic testing

. This first-of-its-kind PICKUP Study–a collaborative effort among ten leading medical institutions including Duke University Health System, University of Pittsburgh Medical Center, Fred Hutchinson Cancer Research Center, MD Anderson Cancer Center, City of Hope, Tulane Medical Center, University of California, San Francisco Medical Center, University of Colorado Denver, Weill Cornell Medicine, and Memorial Sloan Kettering Cancer Center–demonstrated the additive diagnostic value of the Karius Test in managing pneumonia patients with blood cancers.

“Pneumonia commonly complicates hematopoietic cell transplantation and treatment of hematologic malignancies, yet current diagnostic standards identify a causative pathogen in less than half of our patients undergoing bronchoscopy and extensive noninvasive testing,” said Dr. Stephen Bergin, Duke Clinical Research Institute faculty and Principal Investigator for the PICKUP Study. “Often clinicians must weigh the risks of invasive procedures in medically fragile patients with an anticipated low diagnostic yield. The PICKUP Study significantly advances our understanding of how noninvasive plasma microbial cell-free DNA (mcfDNA) sequencing can enhance management of pneumonia.” Pneumonia is a leading cause of death among patients currently undergoing treatment for blood cancer, as they are often at elevated risk of infection throughout their treatment

Identifying the specific cause of pneumonia in patients with blood cancers who are often severely immunocompromised is difficult and critically important to successful treatment. “This well-designed clinical trial conducted at leading academic centers shows that the Karius Test is highly valuable in immunocompromised patients with suspected infection,” said Dr. Ned Sharpless, former Director, National Cancer Institute, and newest Karius board member. “The ability to identify the causal pathogen with true urgency is critical in this patient population, and more rapid diagnosis through use of the Karius Test will reduce suffering and death in these vulnerable patients.”

The Study, “Pneumonia in the ImmunoCompromised – Use of Karius Test for the Detection of Undiagnosed Pathogens (PICKUP),” enrolled 257 hospitalized adults with pneumonia and active hematologic malignancies, had recently undergone a hematopoietic cell transplant, or were receiving immunosuppressive therapy for active graft versus host disease.

“Adding this novel platform to current standards of care significantly improved causative pathogen identification. Future PICKUP Study publications will evaluate the impact of plasma microbial cell-free DNA sequencing on time to diagnosis, detection of co-infections, and potential avoidance of invasive procedures,” said Dr. Stephen Bergin. This primary study endpoint measured the additive diagnostic value of the Karius Test, defined as the percent of patients where the Karius Test identified the cause of pneumonia for whom all usual care testing was negative within 7 days of admission through adjudication. Results showed that the Karius Test identified the probable cause of pneumonia in 12% (21/173) of patients (P<0.001, 95% confidence interval 7.7 yo 18%), when all usual care testing, including bronchoscopy failed to identify a probable cause of pneumonia. The study also evaluated and found that antimicrobial therapy could have been optimized among 81% (17/21) of patients in whom the Karius Test exclusively identified a probable cause of pneumonia

. In several instances, the Karius Test also identified probable causes of pneumonia when all usual care testing failed to find hard-to-identify pathogens such as 

Rhizomucor pusillus, Nocardia cyriacigeorgica, Legionella

. Editors of Clinical Infectious Diseases, a journal published by the Infectious Diseases Society of America (IDSA) concluded, "mcfDNA sequencing is likely to bring added diagnostic value for some heme/STC [hematologic malignancy/stem cell transplant] patients with pneumonia." 

“These patients have much to gain through an improved etiologic diagnosis, and the better and more directed treatment of these infections that make this possible,” said Brad Perkins, Chief Medical Officer at Karius. “This is not only beneficial in the avoidance of the direct morbidity and mortality associated with these infections (26.6% of our enrolled patients died during this study) but in also gaining earlier and uninterrupted access to in-many-cases increasingly life-saving treatments for their underlying disease, in this case hematologic malignancies.”

Karius Inc. Adds Dr. Norman Sharpless, Former National Cancer Institute Head, and Elizabeth O’Farrell, Eli Lilly Veteran, to its Board of Directors

 – Karius®, Inc. a world leader in liquid biopsy for infectious diseases, has announced the inaugural inclusion of the Karius Test® in the 2023 Duke-ISCVID Criteria for Infective Endocarditis by the International Society of Cardiovascular Infectious Diseases (ISCVID)

. Using microbial cell-free DNA from a single blood draw, the Karius Test can detect over 1,000 pathogens, including pathogens responsible for infective endocarditis.

Infective endocarditis is a serious condition that results from an infection leading to inflammation of the heart's lining, valves, or blood vessels. Untreated, it is uniformly fatal. Traditional diagnostic methods, such as blood cultures, can take several days

 to yield results, often fail to identify the underlying pathogen causing an infection,

 and positivity rates are decreased due to prior antimicrobial therapy

. The Duke Criteria was introduced 30 years ago by leading medical experts to enhance and standardize the diagnosis of infective endocarditis. The Criteria has been periodically updated to incorporate technological advances and research discoveries.

The latest version of the Criteria – produced by a working group of 25 subject matter experts from five continents and six infective endocarditis-related subspecialties – has for the first time included hypothesis-free metagenomics sequencing, the technology behind the Karius Test, for fast identification of hard-to-detect pathogens. Specifically, the new Duke-ISCVID Criteria recognizes the high importance of this type of sequencing found in the Karius Test when blood cultures fail to identify a causative pathogen. This acknowledges the Karius Test’s ability to quickly detect difficult-to-diagnose causes of endocarditis such as 

. The working group based their recommendations on multiple studies demonstrating the ability of the Karius Test to rapidly detect these pathogens within a day of specimen receipt. For example, studies have shown that the Karius Test has a higher diagnostic yield than standard testing for identifying causative pathogens in patients with endocarditis (80% yield for Karius Test vs. 30% for blood culture

, n=10) and that the Karius Test can detect the causative pathogens over a much longer period than blood culture (38.1 days for the Karius Test versus 3.7 days for blood culture

 and challenges in diagnosis increases risk for poor health outcomes,” said Brad Perkins, MD, Chief Medical Officer of Karius. “These updated guidelines reflect our real-world experience with use of the Karius Test for infective endocarditis as an important tool for physicians to rapidly and more accurately diagnose and manage infective endocarditis as well as other serious infections, particularly among immunocompromised patients. We appreciate the efforts of these experts for recognizing the growing importance of plasma microbial cell-free DNA metagenomic sequencing as an important new diagnostic test for infective endocarditis patients.”

Karius Inc., a global leader in liquid biopsy for infectious diseases, harnesses metagenomics, next-generation sequencing, and artificial intelligence (AI) to help enhance the precision and speed of pathogen diagnosis. The Karius Test®, used in over 300 healthcare institutions–including 90+ transplant centers and 40+ children’s hospitals across the United States–identifies more than 1,000 pathogens, including viruses, bacteria, fungi, and parasites from a single blood draw typically within a day of sample receipt.
