Data Demonstrating Efficacy of Stool Bacterial Pathogens Panel Presented at ASM Microbe 2017

Four posters describing the Company’s platform to be presented, including a third-party clinical study poster of the Stool Bacterial Pathogens Panel

Salt Lake City, June 1, 2017 – Great Basin Scientific, Inc. (OTCQB: GBSN), a molecular diagnostics company, announced today that it will present three posters describing the reliability and effectiveness of its diagnostic platform to attendees of ASM Microbe 2017, which is being held June 1-5, 2017 in New Orleans. Additionally, Dr. Paul Granato from the Laboratory Alliance of Central New York will present a poster summarizing the results of a multi-site independent clinical study evaluating the Company’s Stool Bacterial Pathogens Panel, which is awaiting 510(k) clearance from the U.S. Food and Drug Administration (FDA). In the independent study, the Company’s Stool Bacterial Pathogens Panel is shown to process results in approximately two hours with superior detection rates of over 97% compared to 51% for conventional culture and EIA methods.

“We are very pleased to continue to show a growing body of data demonstrating how our cost-effective, sample-to-result platform can support our customers’ needs and, we believe, provide better patient outcomes,” said Ryan Ashton, co-founder and chief executive officer of Great Basin Scientific. “We are particularly proud of the results we have seen from our highly-anticipated Stool Bacterial Pathogens Panel, which we believe addresses the testing and reimbursement challenges affecting our healthcare system. Data shows our panel produces highly accurate and fast diagnosis in a multiplex assay that detects the top 90-95 percent of foodborne infections; Salmonella species, Shigella species, Shiga Toxin-producing E. coli (stx1, stx 2, O157 serotype-specific genes), and Campylobacter species (C. jejuni and C. coli).”

Great Basin will present the following posters during this year’s ASM Microbe event:

  • Poster #468, Friday, June 2, 2017

Rapid Detection and Differentiation of the Recently Emerged Multidrug Resistant Candida auris Species and Other Major Clinically Relevant Candida Species Simultaneously and Accurately from Blood Cultures Using a Novel Amplification Process – will be presented in a poster talk by Wanyuan Ao of Great Basin Scientific.

This presentation describes application of Great Basin’s patented AMPED method to the highly specific detection of eight Candida species, including the recently emerging and broadly resistant Candida auris.  The described test is highly specific to the individual species and with limits of detection of less than 100 CFU directly from positive blood cultures without the need for target amplification approaches such as PCR.

  • Poster #473, Friday, June 2, 2017

The Staph ID/R Blood Culture Panel: An FDA Cleared Rapid Detection Method for Staphylococcus and the mecA Gene Direct from Positive Blood Culture; by Jason M. Foulks, Jamie Purcell, Krystle Minear, Annah Frisch, Camrin Rivera, Wanyuan Ao, Maylene Corpuz, Adrianne Clifford, Lindsey Enright, Denton Munns, James Miess, Brandon Cook, Wes Lindsey, Robert Jenison; Great Basin Scientific, Inc., Salt Lake City, UT.

This presentation summarizes the analytical performance data supporting FDA clearance of the Staph ID/R Blood Culture panel. The test was demonstrated to have very broad and sensitive reactivity within the genus and can detect mecA resistance in all Staphylococcus including S. aureus and S. lugdunensis at the species level.

  • Poster #469, Saturday, June 3, 2017

Great Basin Stool Bacterial Pathogens Panel for Rapid Identification of Salmonella, Shigella, Shiga Toxin-Producing E. coli, and Campylobacter in Symptomatic Patients; by Nicole J. Davis, Wanyuan Ao, Emily Wirick, Stefanie Marxreiter, Brandon Cook, Justin Crandall, Megan Warner, Wes Lindsey, and Rob Jenison; Great Basin Scientific, Inc., Salt Lake City, UT.

This presentation summarizes the analytical performance data supporting the clinical evaluation of the Stool Bacterial Pathogens Panel, currently under review by the FDA.

A clinical study of the Company’s Stool Bacterial Pathogens Panel done by third-party researchers will also be presented:

  • Poster #1390, Saturday, June 3, 2017

Comparative Evaluation of a PCR Amplification and Array Detection Stool Bacterial Pathogens Panel with Conventional Methods for Detecting Common Bacterial Enteric Pathogens – will be presented by Dr. Paul Granato of the Laboratory Alliance of Central NY, Syracuse, NY

Posters will be available after ASM Microbe 2017 on the Great Basin website at www.gbscience.com, or on ASM’s website, http://www.asmmicrobe.org/images//AbstractsPull_6-1.pdf.
