Great Basin Scientific Submits 510(k) Application to the FDA for Stool Bacterial Pathogens Panel

Upon anticipated FDA clearance, Company’s syndromic panel will provide cost effective identification for common gastrointestinal pathogens

Salt Lake City, December 19, 2016 – Great Basin Scientific, Inc. (OTCQB: GBSN), a molecular diagnostics company, announced today the 510(k) submission for the Stool Bacterial Pathogens Panel to the U.S. Food and Drug Administration (FDA). Upon anticipated clearance, this syndromic panel for the identification of bacterial causes of acute gastroenteritis will be the Company’s second multiplex panel in its growing menu of sample-to-result assays to diagnose infectious disease. The Company is also seeking CE marking for the panel.

“As the demand in healthcare grows for more targeted and cost effective diagnostic panels, we’re excited about the potential of our Stool Bacterial Pathogens Panel to fill a critical market niche,” said Ryan Ashton, co-founder and Chief Executive Officer of Great Basin Scientific. “By taking a syndromic approach to our panel – testing based on specific set of symptoms – our objective is to offer a simple-to-use, competitively priced panel that is easy for labs and physicians to adopt that will combat misdiagnosis and the spread of infectious disease while improving the antimicrobial stewardship objectives of these facilities.”

The Company’s Stool Bacterial Pathogens Panel is designed to simultaneously detect Salmonella species, Shigella species, Shiga Toxin-producing E. coli (stx1, stx 2, O157 serotype-specific genes), and Campylobacter species (C. jejuni and C. coli), key bacterial pathogens the Company believes better supports customer needs with an easy-to-use workflow of less than two minutes hands-on steps, and a turnaround time of under two hours, compared to conventional tests that are labor intensive, requiring multiple individual tests with poor sensitivity and long turnaround times (96 hours). Great Basin Scientific provides both low-plex and multiplex testing on a single system.

The FDA has 90 days to respond to the Company’s 510(k) submission. “Great Basin has received clearance for its previously-submitted products at, on average, 176 days from submission. With that timeframe as our benchmark, we are preparing for commercial launch of the Stool Bacterial Pathogens Panel late in the first half or early second half of 2017,” Ashton said.

Great Basin Scientific’s system provides both low-plex and multiplex testing, and currently has four commercially available tests; the Staph ID/R Blood Culture Panel, Shiga Toxin Direct Test, tests for Group B Streptococcus (GBS), and toxigenic Clostridium difficile (C. diff). The Company also has four tests in development: Nasal S. aureus Pre-surgical Screen, Candida Blood Infections Panel, CT/NG Test, and the Bordetella Direct test, which is currently in clinical trial.
