Intended Use
The Sensititre 18-24 hour MIC or Breakpoint Susceptibility System is an in vitro diagnostic product for clinical susceptibility testing of non-fastidious isolates.
Device Story
Sensititre 18-24 hour MIC or Breakpoint Susceptibility System is a micro-broth dilution method for antimicrobial susceptibility testing (AST). Device uses dried microtiter plates pre-dosed with Dalbavancin (0.0005–2 µg/mL). Pure culture isolates are standardized and inoculated into plates via Sensititre AutoInoculator/AIM. After 18-24 hours incubation, growth is assessed to determine Minimum Inhibitory Concentration (MIC). Detection methods include manual visual reading (Vizion) or automated fluorescence-based reading (ARIS/AutoReader/OptiRead). Fluorescence technology monitors bacterial surface enzyme activity; enzymatic cleavage of non-fluorescent substrate releases fluorophore, with signal intensity proportional to bacterial growth. Results assist clinicians in determining susceptibility of S. aureus to Dalbavancin. System is intended for clinical laboratory use.
Clinical Evidence
Bench testing only. Study evaluated 401 S. aureus isolates (321 clinical, 80 challenge) including MSSA and MRSA. Compared Sensititre (Vizion and AutoRead) against CLSI M07-A9 reference frozen broth microdilution. Combined EA was 99.2% and CA was 99.5% for both reading methods. Trending analysis showed a tendency for MIC values to be one doubling dilution higher than reference. Very major error rate for non-susceptible MRSA was 33.3% (2/6 isolates).
Indicated for clinical susceptibility testing of non-fastidious Gram-positive organisms, specifically Staphylococcus aureus (MRSA and MSSA), using Dalbavancin in the 0.0005-2 ug/mL range.
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. 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 Parts 801 and 809); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
