Intended Use

VITEK® 2 GN Imipenem is designed for antimicrobial susceptibility testing of Gram-negative bacilli. VITEK 2 GN Imipenem is a quantitative test intended for use with the VITEK 2 and VITEK 2 Compact Systems using VITEK 2 Systems 5.02 Software as a laboratory aid in the determination of in vitro susceptibility to antimicrobial agents. Imipenem has been shown to be active both in vitro and in clinical infections against most strains of the following microorganisms according to the FDA label for the antimicrobial. Active in vitro and in clinical infections: Acinetobacter spp., Citrobacter spp., Enterobacter aerogenes, Escherichia coli, Klebsiella spp., Morganella morganii, Proteus vulgaris, Providencia rettgeri, Pseudomonas aeruginosa, Serratia marcescens. Active in vitro but clinical significance unknown: Providencia stuartii. The VITEK® 2 Antimicrobial Susceptibility Test (AST) is intended to be used with the VITEK® 2 System for the automated quantitative or qualitative susceptibility testing of isolated colonies for the most clinically significant aerobic gram-negative bacilli, Staphylococcus spp., Enterococcus spp., Streptococcus agalactiae, S. pneumoniae and clinically significant yeast. The VITEK 2 Systems (PC) 5.02 Software is intended for use with VITEK 2 and VITEK 2 Compact Systems.

Device Story

VITEK 2 system performs automated antimicrobial susceptibility testing (AST) on isolated bacterial colonies. Input: bacterial isolate diluted in saline, used to rehydrate antimicrobial medium in test card. Operation: VITEK 2 automatically fills/seals card (VITEK 2 Compact uses manual fill/seal); system incubates and monitors growth in card wells over 18 hours. Output: MIC value and interpretive category result. Used in clinical laboratories by technicians/microbiologists. Output assists clinicians in selecting appropriate antimicrobial therapy by determining in vitro susceptibility of pathogens.

Clinical Evidence

Bench testing only. External evaluation compared VITEK 2 Gram Negative Imipenem performance against CLSI broth microdilution reference method using fresh clinical isolates and stock challenge strains. Results demonstrated 95.7% overall Essential Agreement and 94.8% overall Category Agreement. Reproducibility and Quality Control testing met acceptance criteria.

Technological Characteristics

Miniaturized broth microdilution AST card. Automated incubation and optical growth monitoring. Software: VITEK 2 Systems (PC) 5.02. Connectivity: VITEK 2 and VITEK 2 Compact instrument platforms. Quantitative MIC determination.

Indications for Use

Indicated for antimicrobial susceptibility testing of isolated colonies of clinically significant aerobic Gram-negative bacilli, Staphylococcus spp., Enterococcus spp., Streptococcus agalactiae, S. pneumoniae, and yeast. Used as a laboratory aid to determine in vitro susceptibility to antimicrobial agents.

Regulatory Classification

Identification

A fully automated short-term incubation cycle antimicrobial susceptibility system is a device that incorporates concentrations of antimicrobial agents into a system for the purpose of determining in vitro susceptibility of bacterial pathogens isolated from clinical specimens. Test results obtained from short-term (less than 16 hours) incubation are used to determine the antimicrobial agent of choice to treat bacterial diseases.

Special Controls

*Classification.* Class II (special controls). The special control for this device is FDA's guidance document entitled “Class II Special Controls Guidance Document: Antimicrobial Susceptibility Test (AST) Systems; Guidance for Industry and FDA.”

#### D. 510(k) Summary:

VITEK® 2 Gram Negative Imipenem is designed for antimicrobial susceptibility testing of Gram negative microorganisms and is intended for use with the VITEK 2 and VITEK 2 Compact Systems using VITEK 2 Systems (PC) 5.02 software as a laboratory aid in the determination of in vitro susceptibility to antimicrobial agents. VITEK 2 Gram Neqative Imipenem is a quantitative test. Imipenem has been shown to be active against the microorganisms listed below according to the FDA label for the antimicrobial.

Active in vitro and in clinical infections:

| Acinetobacter spp. | Morganella morganii |
|------------------------|------------------------|
| Citrobacter spp. | Proteus vulgaris |
| Enterobacter aerogenes | Providencia rettgeri |
| Escherichia coli | Pseudomonas aeruginosa |
| Klebsiella spp. | Serratia marcescens |

Active in vitro but clinical significance unknown: Providencia stuartii

The antimicrobial presented in VITEK 2 AST Cards is in concentrations equivalent by efficacy to standard method concentrations in mcg/ml. The VITEK 2 AST Cards are essentially miniaturized versions of the doubling dilution technique for determining the minimum inhibitory concentration (MIC) microdilution methodology.

The bacterial isolate to be tested is diluted to a standardized concentration in 0.45 - 0 .50% saline before being used to rehydrate the antimicrobial medium within the card. The VITEK 2 System automatically fills, seals and places the card into the incubator/reader. The VITEK 2 Compact has a manual filling and sealing operation. The VITEK 2 monitors the growth of each well in the card over a defined period of time (up to 18 hours). At the completion cycle, a report is generated that contains the MIC value along with the interpretive category result for each antibiotic contained on the card.

VITEK 2 Gram Negative Imipenem demonstrated substantially equivalent performance when compared with the CLSI broth microdilution reference method, as defined in the FDA Class II Special Controls Guidance Document: Antimicrobial Susceptibility Test (AST) Systems; Guidance for Industry and FDA, Issued August 28, 2009.

The Premarket Notification [510(k)] presents data in support of VITEK 2 Gram Negative Imipenem. An external evaluation was conducted with fresh clinical isolates and stock challenge strains. The external evaluations were designed to confirm the acceptability of VITEK 2 Gram Negative Imipenem by comparing its performance with the CLSI broth microdilution reference method. The data is representative of performance on both the VITEK 2 Compact instrument platforms. VITEK 2 Gram Negative Imipenem using VITEK 2 Systems 5.02 software demonstrated acceptable performance of 95.7% overall Essential Agreement and 94.8% overall Category Agreement. Reproducibility and Quality Control demonstrated acceptable results using both the VITEK 2 and VITEK 2 Compact instrument systems.
