bioMérieux received US FDA 510(k) clearance for its Vitek Reveal AST System, which reports results directly from positive blood cultures.

RT’s Three Key Takeaways

  1. bioMérieux received FDA 510(k) clearance for its Vitek Reveal AST System, which delivers antimicrobial susceptibility testing (AST) results directly from positive blood cultures in 5.5-6 hours, enabling same-day treatment decisions for sepsis patients.
  2. The Vitek Reveal AST System, based on patented metabolomic signature technology, supports rapid and accurate diagnosis, promoting antimicrobial stewardship and potentially reducing antimicrobial resistance (AMR).
  3. This system, which integrates into bioMérieux’s diagnostic portfolio for sepsis and bloodstream infections, received FDA Breakthrough Device Designation in 2022 and is also CE-marked in Europe.

Every year 11 million people worldwide die of sepsis1 and 1.3 million of these deaths are attributable to antibiotic-resistant bacteria2. For clinicians to rapidly optimize therapy and  improve patient care, fast and accurate antimicrobial susceptibility testing (AST) results and interpretation are critical. In addition, fast AST can enable antimicrobial stewardship (AMS) programs which has the potential to reduce antimicrobial resistance (AMR), identified as a global threat by WHO3.

As part of its commitment to combat sepsis and AMR, in 2022 bioMérieux acquired Specific Diagnostics, a US based company that has developed an AST system now called Vitek Reveal. The instrument seamlessly integrates into bioMérieux’s unique and comprehensive portfolio of diagnostic solutions to address bloodstream infections and sepsis.

The modular Vitek Reveal AST system can deliver actionable results for gram-negative bacteria directly from positive blood cultures in an average of 5.5-6 hours4,5 enabling same-day treatment decision-making for patients suffering from bacteremic sepsis.

“Based on its unique, patented metabolomic signature technology, the Vitek Reveal AST System offers an easy-to-use instrument with a broad antimicrobial coverage, small footprint, and modular design for adaptable throughput, well-suited to address the needs of clinical laboratories.” explained Jennifer Zinn, Executive Vice President, Clinical Operations.

“Vitek Reveal is fully aligned with bioMérieux’s priority to provide innovative diagnostics to support antimicrobial stewardship. By integrating this advanced technology in bioMérieux’s portfolio, we are increasing the ability of laboratories to deliver AST results as soon as possible, especially in cases of critical bacteremia-associated  sepsis, which require urgent and appropriate treatment.” added Dr. Charles K. Cooper, Executive Vice President, Chief Medical Officer.

The FDA 510(k) clearance allows the commercialization of Vitek Reveal in the United States. In August 2022, the FDA granted the system with its Breakthrough Device Designation, which is reserved for medical devices that offer significant advantages over existing cleared alternatives, for which no approved alternatives exist, and/or for which device availability is in the best interest of patients6. This AST system is also CE-marked under IVDD* (reagents) and IVDR** (instrument) in Europe.

This project has been funded in part with federal funds from the Department of Health and Human Services (HHS); Administration for Strategic Preparedness and Response (ASPR); Biomedical Advanced Research and Development Authority (BARDA), under contract number 75A50122C00057.
