T2 Biosystems Announces Submission for FDA Breakthrough Device Designation for T2Biothreat Panel

LEXINGTON, Mass., April 27, 2022 (GLOBE NEWSWIRE) T2 Biosystems, Inc. (NASDAQ:TTOO), a leader in the rapid detection of sepsis-causing

pathogens and antibiotic resistance genes, announced today that it has submitted an application with the U.S. Food and Drug Administration (FDA) for Breakthrough Device Designation for the Company s T2Biothreat Panel.

The T2Biothreat Panel is a direct-from-blood test panel designed to run on our commercially

available T2Dx Instrument and is designed to simultaneously detect six biothreat pathogens that are listed by the Centers for Disease Control and Prevention (CDC) as Category A and B

biothreat agents, including Bacillus anthracis, Francisella tularensis, Burkholderia mallei, Burkholderia pseudomallei, Yersinia pestis and Rickettsia prowazekii. The CDC has determined that these organisms represent a national security risk, and

they have a mortality rate of approximately 40% for untreated Burkholderia mallei or Burkholderia pseudomallei infections to nearly 90% for untreated for Yersinia pestis infections.

We are honored to leverage our technology platform to develop products with the potential to protect our nation from the threat of bioterrorism,

stated John Sperzel, Chairman and CEO of T2 Biosystems. We initiated the U.S. clinical trial for the T2Biothreat Panel in December 2021 and we are taking actions to potentially accelerate the commercial availability of our novel T2Biothreat

The FDA Breakthrough Devices Program is a voluntary program for certain medical devices and

device-led combination products that provide for more effective treatment or diagnosis of life-threatening or irreversibly debilitating diseases or conditions. It is available for devices and device-led combination products which are subject to review under a premarket approval application (PMA), premarket notification (510(k)), or De Novo classification request (De Novo request). This program is

intended to help patients have more timely access to these medical devices by expediting their development, assessment, and review, while preserving the statutory standards for PMA approval, 510(k) clearance, and De Novo marketing authorization,

consistent with the FDA s mission to protect and promote public health.

This project has been funded in whole or in part with federal funds from the

Department of Health and Human Services; Office of the Assistant Secretary for Preparedness and Response; Biomedical Advanced Research and Development Authority, under contract number 75A50119C00053.
