Intended Use
The Liofilchem® MIC Test Strip (MTS) is a quantitative method intended for the in vitro determination of antimicrobial susceptibility of bacteria. MTS consists of specialized paper impregnated with a pre-defined concentration gradient of an antimicrobial agent, which is used to determine the minimum inhibitory concentration (MIC) in μg/mL of antimicrobial agents against bacteria as tested on agar media using overnight incubation and manual reading procedures. The Delafloxacin MTS at concentrations of 0.002 - 32 μg/mL should be interpreted at 16-20 hours of incubation. Delafloxacin has been shown to be active both clinically and in vitro against the non-fastidious bacteria listed below according to the FDA drug label: - Gram-negative bacteria - Escherichia coli - Klebsiella pneumoniae - Enterobacter cloacae - Pseudomonas aeruginosa Delafloxacin has been shown to be active in vitro only against the non-fastidious bacteria listed below according to the FDA drug label: - Klebsiella (Enterobacter) aerogenes - Klebsiella oxytoca - Proteus mirabilis
Device Story
Manual antimicrobial susceptibility test system; uses specialized paper strip impregnated with predefined exponential concentration gradient of Delafloxacin (0.002-32 μg/mL). Strip applied to inoculated Mueller Hinton agar; incubated 16-20 hours at 35°C. Forms symmetrical inhibition ellipse; MIC read manually at intersection of ellipse edge and strip. Provides quantitative MIC values to guide antibiotic therapy selection. Used in clinical microbiology laboratories by trained personnel. Benefits include standardized, quantitative susceptibility determination for non-fastidious Gram-negative organisms.
Clinical Evidence
No clinical data provided. Substantial equivalence is supported by bench testing demonstrating performance of the Delafloxacin MTS against the specified non-fastidious bacterial organisms compared to reference methods.
Technological Characteristics
Specialized paper strip impregnated with a predefined concentration gradient of Delafloxacin (0.002-32 µg/mL). Quantitative antimicrobial susceptibility test. Manual reading of inhibition ellipse on agar media. No electronic components, software, or energy source.
Indications for Use
Indicated for in vitro determination of antimicrobial susceptibility of non-fastidious bacteria (E. coli, K. pneumoniae, E. cloacae, P. aeruginosa, K. aerogenes, K. oxytoca, P. mirabilis) to Delafloxacin. For prescription use only.
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.

Dear Laura Koeth:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). 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, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
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 Part 801 and Part 809); medical device reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR
{1}------------------------------------------------
Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm for the CDRH's Office of Surveillance and Biometrics/Division of Postmarket Surveillance.
For comprehensive regulatory information about mediation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/MedicalDevices/DeviceRegulationandGuidance/) and CDRH Learn (http://www.fda.gov/Training/CDRHLearn).
