Intended Use
The CEDIA Cyclosporine Plus Assay is for the quantitative determination of cyclosporine in human whole blood using automated clinical chemistry analyzers as an aid in the management of therapy in kidney, liver, and heart transplants. The CEDIA Cyclosporine Calibrators are used to calibrate the CEDIA Cyclosporine Plus Assay in human whole blood.
Device Description
The CEDIA Cyclosporine Plus Assay is a two-reagent set intended to be used with automated clinical chemistry analyzers. The assay uses recombinant DNA technology (US Patent No. 4708929) to produce a unique homogeneous enzyme immunoassay system. The assay is based on the bacterial enzyme ß galactosidase, which has been genetically engineered into two inactive fragments, termed Enzyme Acceptor (EA) and Enzyme Donor (ED) spontaneously reassociate to form fully active enzyme that, in the assay format, cleaves a substrate, to generate a color change that can be measured spectrophotometrically. In the CEDIA Cyclosporine Plus Assay, drug in the sample competes with drug conjugated to ED for antibody binding sites. If drug is present in the sample, it binds to antibody, leaving the EDdrug conjugate free to reassociate with EA to form active ß-galactosidase. If no drug is present in the sample, antibody binds to the ED-cyclosporine conjugate, inhibiting the reassociation of inactive B-galactosidase fragments, and thus reducing the amount of active enzyme formed. The amount of active enzyme formed, and resulting absorbance change, is proportional to the amount of CEDIA Cyclosporine Plus Assay present in the sample.

No
The device description details a homogeneous enzyme immunoassay based on recombinant DNA technology and spectrophotometric measurement. There is no mention of AI or ML in the intended use, device description, or performance studies.

No.
The device is an in vitro diagnostic (IVD) assay designed to quantitatively measure cyclosporine levels in human whole blood. It is used as an "aid in the management of therapy," meaning it provides information for treatment decisions, rather than directly treating a condition itself.

Yes

The device aids in the management of therapy by quantitatively determining cyclosporine levels in blood, which is a diagnostic function to monitor drug efficacy and toxicity in transplant patients.

No

The device description clearly states it is a "two-reagent set" and describes a chemical assay based on enzyme activity and spectrophotometric measurement, indicating it is a hardware/chemical-based diagnostic assay, not software only.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use explicitly states it's for the "quantitative determination of cyclosporine in human whole blood." This involves testing a sample taken from the human body (whole blood) outside of the body (in vitro).
  • Purpose: The purpose is "as an aid in the management of therapy in kidney, liver, and heart transplants." This indicates it's used for diagnostic or monitoring purposes related to a medical condition or treatment.
  • Device Description: The description details a "homogeneous enzyme immunoassay system" that measures a substance in a sample. This is a common type of in vitro diagnostic test.
  • Sample Type: The assay uses "human whole blood," which is a biological sample.
  • Performance Studies: The document includes performance data like accuracy and imprecision, which are standard for IVD devices to demonstrate their reliability for clinical use.
  • Predicate Device: The mention of a "Predicate Device" (P920031; EMIT 2000 Cyclosporine Specific Assay) strongly suggests this device is being compared to a previously cleared IVD, a common process for regulatory submission of new IVDs.

All these factors align with the definition and characteristics of an In Vitro Diagnostic device.

Dear Mr. Smith:

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 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.
