Accelerate Diagnostics Receives FDA Clearance

for the Accelerate Pheno System and Accelerate PhenoTest BC Kit

First fully automated solution permitted by the FDA for quantitative antibiotic susceptibility testing direct from patient samples

TUCSON, Ariz., Feb 23, 2017 (GLOBE NEWSWIRE) — Accelerate Diagnostics, Inc. (Accelerate) today announced that the U.S. Food and Drug Administration has granted the de novo request to market the Accelerate Pheno™ system and Accelerate PhenoTest™ BC kit for identification and antibiotic susceptibility testing of pathogens directly from positive blood culture samples. The blood culture kit is indicated for susceptibility testing of specific pathogenic bacteria commonly associated with bacteremia, the leading cause of sepsis.

The Need

The Centers for Disease Control and Prevention estimate at least 2 million people each year are infected with antibiotic resistant bacteria across the U.S. In addition, antibiotic resistance contributes to the morbidity and mortality of healthcare-associated infections (HAI) that kill an estimated 75,000 people annually.1

Early diagnosis of antibiotic resistant bacteria is critical to providing patients optimal therapy. The only way to know which therapy will work is to test a range of antibiotics. Typical, conventional antibiotic susceptibility testing requires time consuming manual procedures, resulting in laboratory processing time that often exceeds 48 hours, leaving clinicians with incomplete information to provide definitive treatment during this critical time period.

The Solution

Using the Accelerate Pheno™ system and PhenoTest™ BC kit, laboratories can substantially reduce the processing time by testing directly from positive blood culture samples, which enables clinicians to provide patients optimal therapy about 1-2 days faster than conventional methods.

The BC kit is capable of simultaneous detection and identification of multiple microbial targets followed by susceptibility testing of appropriate detected bacterial organisms using morphokinetic cellular analysis (MCA) of individual microbial cells and colonies under the challenge of antibiotics. Results are intended to be interpreted in conjunction with Gram stain results.

The Accelerate PhenoTest™ BC kit includes 140 assays for both identification and susceptibility testing, of which 116 were submitted to the FDA.

The Study

The Accelerate clinical study included more than 1,800 samples across 13 trial sites and exceeded the positive percent agreement (PPA) required by the FDA for identification and antimicrobial susceptibility testing. The study showed overall sensitivity of 97.5% and specificity of 99.3% for identification. For susceptibility, overall essential and categorical agreement versus the gold standard was 96.3% and 96.4% respectively2.
