CARB-X Backs Neonatal Sepsis Diagnostic Platform By QuantaMatrix

Technology aims to deliver results within 6 hours from very small blood samples

Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator (CARB-X) has awarded QuantaMatrix Inc. US$2.85M to execute a workplan to develop its rapid diagnostic platform to detect sepsis, especially in vulnerable neonates. The test aims to deliver results within just 6 hours from very small blood samples of 1 to 2 milliliters.

If successful, the diagnostic could significantly improve patient outcomes as existing diagnostic methods can take several days. The BARNARDS study estimated that 2.5 million neonates or infants in the first month of life die annually of sepsis. Since neonatal sepsis progresses rapidly, it requires immediate treatment with IV fluids and antibiotics. The risk of death from neonatal sepsis increases 7.6% every hour a treatment is delayed.

QuantaMatrix is applying its rapid blood culture technology directly from whole blood, with the addition of a brief enrichment step and its multi-marker QMAP “One-pot Assay” to address technological challenges that have limited innovation in this space. With minimal sample processing and a large commercial footprint, this program could make testing for neonatal sepsis more accessible, globally.

“Neonatal sepsis remains one of the most urgent diagnostic challenges due to the rapid disease progression, the time limitations of current culture-based methods, and the low sample volumes. QuantaMatrix’s platform has the potential to significantly improve early intervention and survival rates,” said Erin Duffy, PhD, R&D Chief of CARB-X. “CARB-X is proud to support the advancement of technologies that can bridge critical gaps in neonatal sepsis diagnostics and strengthen global efforts against antimicrobial resistance.”

“QuantaMatrix’s ambition extends beyond positioning ourselves at the forefront of rapid AST. Our vision is to become a global leader in Microbiology,” said Dr. SungHoon Kwon, President and CEO of QuantaMatrix.

In March 2024, CARB-X launched a new funding solicitation to fill major R&D gaps in the global antibacterial development pipeline. More than 300 initial applications were accepted in four distinct product themes: therapeutics for infections caused by Gram-negative pathogens, novel approaches to the prevention of invasive disease caused by Staphylococcus aureus or Escherichia coli, diagnostics for neonatal sepsis, proof-of-concept for novel sample types for diagnosing lower-respiratory tract infections. Ten awards were announced from the first cycle of the 2024 funding round. Additional projects from the second cycle will be announced this year. CARB-X will begin accepting applications for the second cycle of the 2025 funding round from December 1 to December 12. Register for the CARB-X newsletter to receive updates.

When CARB-X was founded in 2016, the early-stage antibiotic pipeline was stalled. Since its inception, CARB-X has supported 117 R&D projects in 15 countries, and CARB-X product developers have made significant progress: 22 projects have advanced into or completed clinical trials; 14 remain active in clinical development, including late-stage clinical trials; and 3 products have reached the market. Additionally, more than 10 product developers with active R&D projects have already secured advanced development partnerships to support their clinical development after leaving the CARB-X portfolio. All CARB-X-funded product developers are contractually obligated to develop a Stewardship and Access Plan for their product, outlining strategies to ensure responsible stewardship and appropriate access in low- and middle-income countries.

CARB-X is funded in part with federal funds from the U.S. Department of Health and Human Services (HHS); Administration for Strategic Preparedness and Response; Biomedical Advanced Research and Development Authority (BARDA) under agreement number 75A50122C00028 and by awards from Wellcome (WT224842), the UK Department of Health and Social Care’s Global Antimicrobial Resistance Innovation Fund (GAMRIF), the Gates Foundation, Germany’s Federal Ministry of Research, Technology and Space (BMFTR), the Public Health Agency of Canada (PHAC), the Novo Nordisk Foundation, Italy’s Ministry of Economy and Finance (MEF), and Japan’s Ministry of Health. The U.S. National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH) in HHS, provides support in the form of in-kind services through access to a suite of preclinical services for product development.
