iCubate® blood stream infection test effective in hospital setting

Findings published in the Journal of Clinical Microbiology

Huntsville, Ala. — November 5, 2015 — The iCubate iC-GPC Assay, a test developed by the Huntsville, Ala. company for the rapid identification of gram positive bacteria, showed high levels of efficacy in a clinical setting.

The research findings have been published online first in The Journal of Clinical Microbiology and will appear in the journal’s December print publication.

Authors are Blake W. Buchan and Garrett C. Reymann, the Medical College of Wisconsin and the Wisconsin Diagnostic Laboratory; Paul A. Granato, the Laboratory Alliance of Central New York, LLC and the Department of Pathology, SUNY Upstate Medical University; and Brenda R. Alkins, Patricia Jim and Stephen Young, Tricore Reference Laboratory and the University of New Mexico.

At those clinical sites, the iCubate iC-GPC Assay was evaluated using 203 clinical and seeded specimens containing five gram-positive bacterial species and three associated genetic resistance determinants in positive blood culture broths. The assay demonstrated sensitivity of over 93 percent and specificity of 98-100 percent.

According to the publication, “the iC-GPC assay provides a molecular option for the rapid, on-demand analysis of positive blood cultures.”

The paper also cites possible advantages of the product. “A potential benefit of the iC-GPC assay is the use of a single, closed-system consumable cassette. This enables simplified assay set-up (< 5 min. hands on time) and also aids in reducing the risk of aerosolization of potentially infectious organisms and amplicon contamination. Furthermore, the iC- Processor is capable of random-access processing of up to 4 iC-cassettes simultaneously using an instrument that has a small footprint. Combined, these attributes may positively impact safety, workflow, and throughput when compared to other currently available FDA- cleared molecular platforms and assays for the direct identification of bacteria present in positive blood cultures” (emphasis added by iCubate).

“These findings are an important milestone for the company. We are one step closer to having this product available to help healthcare providers better treat their patients,” said Carter Wells, CEO of iCubate®.

“Combining the innovative arm-PCR technology pioneered by Jian Han, MD, PhD, iCubate’s Founder and Chairman, along with our talented team members, iCubate is positioned for success in this growing market,” continued Wells.

iCubate’s iC-GPC™ panel will include the detection of multiple pathogenic targets and antibiotic resistance markers to further aid physicians with diagnosis.

The iCubate® product is currently “Research Use Only”. These data were collected from an initial beta trial evaluation of the iC-GPC™ product.

iCubate® is seeking FDA clearance as an in-vitro diagnostic test to be used for the identification and detection of Gram-positive bacteria, which are the most common cause of bacterial bloodstream infections. iCubate® is currently conducting full clinical trials and moving forward on a regulatory path with the goal of obtaining FDA 510(k) clearance.

Gram–positive bacteria, such as Staphylococcus, are the most common bacterial contaminants of blood. FDA approval of the iCubate System to detect Gram-positive bacteria has the potential to help physicians better diagnose and treat bloodstream infections.
