T2 Biosystems Highlights New Article Published in The Lancet: Changing the Culture of Blood Culture

LEXINGTON, Mass., Sept. 23, 2024 (GLOBE NEWSWIRE) — T2 Biosystems, Inc. (NASDAQ: TTOO) (the “Company”), a leader in the rapid detection of sepsis-causing pathogens and antibiotic resistance genes, today highlighted a recently published article in The Lancet, a world-leading medical journal. The article titled “Changing the Culture of Blood Culture” was authored by Sally Davies, Richard A Marfuggi, Rick A Bright, Steve Brozak, and Michael Osterholm on September 20, 2024.

“The T2 Biosystems team is commercializing the only FDA-cleared direct-from-blood diagnostics able to rapidly detect bacterial and fungal pathogens, and we applaud the authors for raising awareness of the limitations of blood culture,” stated John Sperzel, Chairman and CEO of T2 Biosystems. “As noted by the authors, rapid culture-independent diagnostics have the potential to improve health outcomes and strengthen the global response to infectious diseases, and T2 Biosystems is working to leverage our technology to further advance the field.”

The authors highlighted certain weaknesses of blood culture, the ideal characteristics of culture-independent diagnostics, how to move beyond the culture of blood culture, and how to implement rapid culture-independent diagnostics:

• Weaknesses of blood culture: blood culture has poor sensitivity, especially with low blood volumes; it is time-consuming, typically taking 24-72 hours for initial results; it is vulnerable to contamination; it has reduced effectiveness in people who have received antibiotics; and is a labor-intensive process requiring skilled technicians.
• Ideal characteristics of culture-independent diagnostics: culture-independent diagnostic tests need to display proven accuracy (i.e., sensitivity and specificity); they need to be accurate despite previous antimicrobial therapy; they need to provide results in 3-5 hours; they need to detect a range of bacterial, fungal, and antimicrobial resistance pathogens; they need to be low-cost, easy to use, and accessible; and they should have a low cross-contamination risk and low sample volume requirements.
• How to move beyond the culture of blood culture: the ongoing crisis in blood-culture availability should encourage the development and implementation of more efficient and resilient diagnostic methods. Moving beyond the culture of blood culture will require changes to reimbursement codes and practices for new diagnostic technologies. Governments, health-care systems, and private-sector entities should designate funding for new diagnostic technologies. Frugal innovation will be important in these efforts, combining state-of-the-art technologies with cost-effective solutions to make advancements accessible, even in resource-limited settings.
• Implementation of rapid, culture-independent diagnostics: rapid, accurate diagnostics should be integrated into antimicrobial-stewardship programs to enable targeted therapy. Once implemented, global collaboration is needed to share best practices, coordinate research efforts, and ensure equitable access to new diagnostics. Culture-independent diagnostics have the potential to improve health outcomes and strengthen the global response to infectious diseases.

About the T2Bacterial Panel
The T2Bacteria^® Panel is the only FDA-cleared diagnostic test able to detect sepsis-causing bacterial species directly-from-blood, in just 3-5 hours, without the need to wait days for a positive blood culture. The T2Bacteria Panel runs on the FDA-cleared T2Dx^® Instrument and simultaneously detects six bacterial species with 90% sensitivity and 98% specificity, including, Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Escherichia coli. The six species detected by the T2Bacteria Panel account for nearly 75% of all bacterial bloodstream infections in the U.S.

About the T2Candida Panel
The T2Candida^® Panel is the only FDA-cleared diagnostic test able to detect sepsis-causing Candida species directly-from-blood, in just 3-5 hours, without the need to wait days for a positive blood culture. The T2Candida Panel runs on the FDA-cleared T2Dx Instrument and simultaneously detects five Candida species with 91% sensitivity and 99% specificity, including, Candida albicans, Candida tropicalis, Candida parapsilosis, Candida krusei, and Candida glabrata. According to the U.S. Centers for Disease Control and Prevention (CDC), the five species detected by the T2Candida Panel account for up to 95% of all Candida bloodstream infections in the U.S.

About the T2Resistance Panel
The T2Resistance^® Panel is a CE-marked diagnostic test able to detect antibiotic resistance genes directly-from-blood, in just 3-5 hours, without the need to wait days for a positive blood culture. The T2Resistance Panel runs on the FDA-cleared T2Dx Instrument and simultaneously detects thirteen antibiotic resistance genes from both Gram-positive and Gram-negative bacterial pathogens, including KPC, OXA-48, CTX-M-14/15, AmpC (CMY/DHA), NDM/IMP/VIM, mecA/C, and vanA/B. The T2Resistance Panel is marketed and sold in Europe under a CE-mark and was granted Breakthrough Device designation from the FDA, which will provide for a prioritized FDA review process.
