Clinical Performance and Reproducibility of the Accelerate PhenoTest™ Blood Culture (BC) Kit With New Antibiotic Wave I Updates
- Conditions
- Bacteremia
- Interventions
- Device: Specimens that meet inclusion criteria
- Registration Number
- NCT04295915
- Lead Sponsor
- Accelerate Diagnostics, Inc.
- Brief Summary
This is a performance and reproducibility study to validate new or updated antimicrobials on the Accelerate PhenoTest™ BC kit. The data from this study will be used to support the submission to the FDA for clearance in the US and for global registrations of the device intended for in vitro diagnostic use.
- Detailed Description
This clinical study entitled "Clinical Performance and Reproducibility of the Accelerate PhenoTest™ BC Kit Using the Accelerate Pheno™ System with New Antibiotic Wave I Updates for Antimicrobial Susceptibility Testing of Positive Blood Culture Specimens" is designed to demonstrate the clinical performance and reproducibility of the new or updated antimicrobials on the Accelerate PhenoTest™ BC kit, which was previously FDA-cleared in February 2017.
Clinical performance and reproducibility evaluations will be conducted at a minimum of three sites to determine the clinical performance of the new or updated antimicrobials from a combination of fresh (de-identified, remnant specimens) and contrived positive blood culture samples, to include at least 375 total specimens.
The study sites selected will have expertise in blood culture diagnostics and will be able to conduct the study in accordance with this protocol and Good Clinical Practices (GCP). Additionally, prior to study initiation, each site will have approval from the local Institutional Review Board (IRB).
It is anticipated that the data from this study will be used to support the submission to the FDA for clearance in the US and for global registrations of the device intended for in vitro diagnostic use.
