Intended Use
The Sensititre 18 - 24 hour MIC or Breakpoint Susceptibility System is an in vitro diagnostic product for clinical susceptibility testing of gram negative and gram positive organisms.
Device Story
Sensititre 18-24 hour MIC or Breakpoint Susceptibility System performs in vitro diagnostic susceptibility testing of gram-negative and gram-positive organisms. Device utilizes dilution panels to determine Minimum Inhibitory Concentration (MIC) or breakpoint susceptibility for specific antimicrobial agents. This submission adds Moxifloxacin to existing panels for gram-negative isolates. Used in clinical laboratory settings by trained personnel. Results assist clinicians in selecting appropriate antimicrobial therapy for patients with bacterial infections.
Clinical Evidence
Bench testing only. Performance evaluated via in vitro susceptibility testing of gram-negative isolates. Data provided for Klebsiella pneumoniae (primary indication) and in vitro data without clinical correlation for Citrobacter freundi, Enterobacter cloacae, Escherichia coli, Klebsiella oxytoca, and Proteus mirablis.
Technological Characteristics
In vitro diagnostic susceptibility test panel; dilution-based MIC determination; range 0.004-16ug/ml for Moxifloxacin; 18-24 hour incubation period.
Indications for Use
Indicated for clinical susceptibility testing of gram negative and gram positive organisms. This specific submission adds Moxifloxacin (0.004-16ug/ml) for testing gram negative isolates, specifically Klebsiella pneumoniae. In vitro data provided for Citrobacter freundi, Enterobacter cloacae, Escherichia coli, Klebsiella oxytoca, and Proteus mirablis.
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 Ms. Knapp:
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.
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 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 Parts 801 and 809); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820).

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 information about the application of labeling requirements to your device, or questions on the promotion and advertising of your device, please contact the Office of In Vitro Diagnostic Device Evaluation and Safety at (301) 594-3084. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (301) 443-6597 or at its Internet address http://www.fda.gov/cdrh/dsma/dsmamain.html.
