Intended Use

The Sensititre 20-24-hour Haemophilus influenzae/Streptococcus pneumoniae MIC or Breakpoint Susceptibility System is an in vitro diagnostic product for clinical susceptibility testing of fastidious isolates. This 510(k) is for dalbavancin in the dilution range of 0.0005 - 2µg/ml with new FDA breakpoints for testing fastidious Streptococcus spp. on the Sensititre 20 - 24-hour Haemophilus influenzae/Streptococcus pneumoniae MIC or Breakpoint Susceptibility System. Dalbavancin has been shown to be active both clinically and in vitro against the following organisms according to the FDA drug label: Streptococcus agalactiae Streptococcus pyogenes Streptococcus anginosus group (S. anginosus, S. constellatus and S. intermedius)

Device Story

The Sensititre 20-24-hour system is an in vitro diagnostic device used in clinical laboratories for antimicrobial susceptibility testing. It utilizes microbroth dilution to determine the Minimum Inhibitory Concentration (MIC) or breakpoint of dalbavancin against fastidious Streptococcus species. The system provides quantitative susceptibility results, which assist clinicians in selecting appropriate antibiotic therapy for patients with bacterial infections. The device is operated by laboratory personnel in a clinical setting. Results are interpreted by the healthcare provider to guide clinical decision-making regarding antibiotic treatment, potentially improving patient outcomes by ensuring targeted therapy.

Clinical Evidence

No clinical data provided. The submission relies on bench testing to demonstrate performance for antimicrobial susceptibility testing of the specified organisms.

Technological Characteristics

Microbroth dilution susceptibility system. Utilizes pre-filled microtiter plates containing varying concentrations of dalbavancin (0.0005-2ug/ml). Designed for 20-24 hour incubation. In vitro diagnostic use.

Indications for Use

Indicated for clinical susceptibility testing of fastidious isolates, specifically Streptococcus agalactiae, Streptococcus pyogenes, and Streptococcus anginosus group (S. anginosus, S. constellatus, and S. intermedius) using dalbavancin.

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 Dylan Staats:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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.

{1}------------------------------------------------

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) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; 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 https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.
