Intended Use

This submission is for Etest Doripenem for MIC determinations across 0.002-32 µg/mL with Gram negative aerobic bacteria such as Enterchacteriaceae, Accretobacer baumanii, Pseudomonas aeraginesa and Gram negative anaerobic bacteria such as Bacteroides aacae, B. fragilis, B.thetaiotaorracron, B. uniformis and B. ulgatus. Etest is a quantitative technique for determination of antimicrobial susceptibility of both nonfastidious Gram negative and Gram positive aerobic bacteria such as Enterchaceriane, Pseudomnas, Staphylococus and Enteroxous species and fastidious bacteria, such as anaerobes, N. gonombeae, S. preumoniae, Streptoxous and Haemophilus species. The system comprises a predelined antibiotic gradient which is used to determine the Minimum Inhibitory Concentration (MIC) in ug/ mL of different antimicrobial agents against microorganisms as tested on agar using overnight incubation.

Device Story

Etest is a quantitative antimicrobial susceptibility test; utilizes predefined antibiotic gradient on a test strip; applied to inoculated agar plates; incubated overnight. Principle: antibiotic diffuses into agar, creating a concentration gradient; bacterial growth inhibition forms an elliptical zone of inhibition. Intersection of growth with the strip indicates the Minimum Inhibitory Concentration (MIC) in µg/mL. Used in clinical microbiology laboratories by trained technicians. Provides quantitative MIC values to guide clinicians in selecting appropriate antibiotic therapy for bacterial infections. Benefits: precise susceptibility data compared to qualitative methods; aids in optimizing dosing regimens.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on bench testing of the Etest system's performance in determining MIC values for Doripenem against specified bacterial isolates compared to reference methods.

Technological Characteristics

In vitro diagnostic device; consists of a reagent-impregnated strip creating a stable antibiotic concentration gradient. Principle: agar diffusion. Dimensions: strip form factor. Connectivity: none (standalone). Sterilization: N/A. Software: none.

Indications for Use

Indicated for MIC determination of Doripenem (0.002-32 µg/mL) in Gram-negative aerobic bacteria (e.g., Enterobacteriaceae, Acinetobacter baumannii, Pseudomonas aeruginosa) and Gram-negative anaerobic bacteria (e.g., Bacteroides spp.). Also indicated for general antimicrobial susceptibility testing of nonfastidious Gram-negative/positive aerobic bacteria and fastidious bacteria (anaerobes, N. gonorrhoeae, S. pneumoniae, Streptococcus, Haemophilus).

Regulatory Classification

Identification

An antimicrobial susceptibility test powder is a device that consists of an antimicrobial drug powder packaged in vials in specified amounts and intended for use in clinical laboratories for determining in vitro susceptibility of bacterial pathogens to these therapeutic agents. Test results are used to determine the antimicrobial agent of choice in the treatment of bacterial diseases.

You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, isting of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Degister. Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must COMPLY with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). {1}------------------------------------------------ Page 2 - This letter will allow you to begin marketing your device as described in your Section 510/k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market. If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of In Vitro Diagnostic Device Evaluation and Safety at 240-276-0450.
