Pathogenomix Bacteria Detection Assay Granted FDA Breakthrough Designation

Pathogenomix, a next generation sequencing, pathogen diagnostic company, has been granted US Food and Drug Administration (FDA) Breakthrough Device Designation for its Patho-Seq assay.

Pathogenomix Bacteria Detection Assay Granted FDA Breakthrough Designation

Patho-Seq is designed for the rapid detection and identification of hundreds of clinically relevant bacteria for a broad list of clinical conditions and sample types, including sepsis from whole blood samples and bacterial meningitis from CSF. The FDA has granted Patho-Seq a Breakthrough Device Designation due to its significant advantages compared to current FDA-approved methods for the diagnosis of pathogenic bacteria in cases where infection may threaten life or long-term health.

Chris Risley, executive chairman of Pathogenomix, said: “Perhaps the most important advantage of using next generation sequencing for bacterial ID is its ability to rapidly detect any of hundreds of infectious bacteria from a single test run, without requiring a specific hypothesis from the clinician about what might be causing the infection. In the other diagnostics, in order to select the correct growth medium or NAAT, the clinician must have a strong hypothesis about which one of hundreds of potential pathogens may be infecting their patient. The same breadth also allows multiple bacterial ID’s from polymicrobial samples in cases where more than one species may be contributing to the infection. In addition, if a sample is taken after the patient has been treated with antimicrobials, then traditional culture for ID often delivers a false negative. Patho-Seq can identify all bacteria even if the sample was taken after the patient was treated.”

Pathogenomix, Inc. collaborated with Mayo Clinic on the development of the techniques and data which supported the application for this FDA Breakthrough Device Designation.

The Patho-Seq test has the potential to significantly advance infectious disease treatment through its targeted 16S sequencing approach. 13.9% of all hospital admissions in 2018 were for infections with a likely bacterial organism. A review of the leading cause of infectious disease admissions, sepsis, found that of the 2.5 million cases studied, the causative organism was never identified in over 70% of the cases. Sepsis alone was the cause for over 2 million hospital admissions and 200,000 deaths in 2018, with a mean medical cost ranging from $16,324 – $38,298 per patient.

Patients can develop systemic infections, like sepsis, from uncontrolled infections at many sites in the body, representing a massive variety in potentially causative organisms. Current FDA-approved methods don’t address such a breadth of causes with a single test. Patho-Seq’s approach answers this broad spectrum problem. As a rapid, hypothesis-free diagnostic that can detect any of hundreds of bacteria, Patho-Seq addresses the critical weaknesses of current FDA-approved methods for the diagnosis of inpatient bacterial infections. For many infectious organisms, the Patho-Seq test can return results more than 48 hours faster than the currently approved Standard of Care tests. Patho-Seq was granted Breakthrough Device Designation for the identification of infectious bacteria from sepsis and bacteremia, bacterial meningitis, joint and implant infections, and tick-borne bacterial infections. Pathogenomix’s customers in research institutions use it for a much broader range of sample source sites in the body and for a much broader range of pathogen ID’s.

Through the Breakthrough Device Program, FDA will provide Pathogenomix with continued guidance and accelerated review for its subsequent De Novo FDA approval process. When approved, FDA Breakthrough Designated Devices will also be eligible for new Center for Medicare and Medicaid Services (CMS) rules to incentivise the rapid adoption of Breakthrough-Designated Technologies at U.S. Hospitals.
