The QMS® Everolimus Assay is intended for the quantitative determination of Everolimus in human whole blood on automated clinical chemistry analyzers. The results obtained are used as an aid in the management of kidney and liver transplant patients receiving Everolimus therapy. This in vitro diagnostic device is intended for clinical laboratory use only.
The QMS® Everolimus Assay consists of separately packaged reagents (R1, R2, and Precipitation Reagent) with the following contents and configurations.
R1 Antibody Reagent: <1.0% Anti-Everolimus polyclonal antibody (rabbit) in a buffer as stabilizer and <0.09% sodium azide as preservative. 1 x 22 mL
R2 Microparticle Reagent: <0.6% Everolimus-coated microparticles in buffer containing <0.05% sodium azide as preservative. 1 x 8 mL
Precipitation Reagent: Precipitating reagent, and <0.09% sodium azide as preservative. 1 x 8 mL
The reagents are supplied ready-to-use in liquid form in plastic HDPE bottles, for storage at 2 to 8°C. The reagent set is sufficient for 100 tests.
Here's an analysis of the acceptance criteria and study findings for the Thermo Scientific QMS® Everolimus Assay, based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria / Performance Claim | Reported Device Performance |
|---|---|
| Analytical Sensitivity (LDD) | ≤0.51 ng/mL |
| Functional Sensitivity (LOQ) | 2.0 ng/mL (at 20%CV acceptable inter-assay precision and recovery) |
| Precision (Total run %CV) | ≤10.0% |
| Linearity (Assay range 2-20 ng/mL) | Performs in a linear fashion |
| Method Comparison with LC/MS (Correlation Equation) | y = 1.07x + 0.19 |
| Method Comparison with LC/MS (Correlation Coefficient) | R = 0.97 |
2. Sample size used for the test set and the data provenance
- Test Set Sample Size: The document does not explicitly state the total number of samples used for the "Method Comparison" study or for other performance tests like precision and linearity. It mentions "Everolimus samples were tested for precision" and "Samples were tested in the QMS® Everolimus Assay and compared to LC/MS."
- Data Provenance: The document does not provide details on the country of origin of the data or whether the data was retrospective or prospective.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
This section is not applicable as the device is an in-vitro diagnostic assay for quantitative determination of a drug in human whole blood. The "ground truth" for method comparison and analytical performance is established by comparison to a reference method (LC/MS) or by known concentrations of the analyte in manufactured samples (e.g., calibrators, controls). It does not involve human expert interpretation of images or clinical data.
4. Adjudication method for the test set
This is not applicable for this type of in-vitro diagnostic device. Analytical studies like method comparison and precision do not typically involve adjudication by experts.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
This is not applicable. This device is an automated in-vitro diagnostic (IVD) assay, not an AI-powered diagnostic tool requiring human interpretation or an MRMC study.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This is essentially how the device operates. The QMS® Everolimus Assay is an automated clinical chemistry assay that provides quantitative results. Its performance (analytical sensitivity, precision, method comparison) is evaluated in a standalone manner, meaning the assay itself generates the readings, which are then used by clinicians for patient management. There isn't a "human-in-the-loop" for the direct measurement process itself, although clinicians interpret the results.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
The ground truth for the analytical performance studies appears to be:
- LC/MS (Liquid Chromatography/Mass Spectrometry): For the "Method Comparison" study, LC/MS served as the reference method for determining Everolimus concentrations.
- Known Concentrations: For studies like Analytical Sensitivity (LDD), Functional Sensitivity (LOQ), Precision, and Dilution Recovery, the ground truth would be based on precisely prepared samples with known concentrations of Everolimus (e.g., calibrators, controls, spiked samples).
8. The sample size for the training set
This information is not provided in the summary. For an IVD assay like this, there isn't a traditional "training set" in the sense of machine learning algorithms. Instead, assay development involves extensive testing and optimization using various formulations and spiked samples to establish performance characteristics, rather than a distinct training/test split of clinical data.
9. How the ground truth for the training set was established
As noted above, a distinct "training set" with ground truth in the machine learning sense is not explicitly described or typically applicable for IVD assay development. The "ground truth" during development and optimization would involve using:
- Reference standards: Pure Everolimus used to create calibrators and controls with known concentrations.
- LC/MS analysis: As a highly accurate reference method to verify concentrations in samples during development.
- Spiked samples: Whole blood samples spiked with known amounts of Everolimus to assess recovery and other analytical parameters.

| In particle agglutination assays, the degreeof agglutination (detected by optical methodat 700 nm) is inversely proportional to thequantity of free drug in the reaction well.Hence, if no drug is present in the sample,the antibodies in the QMS® EverolimusAntibody Reagent (R1) will bind only to thebound drug on the particle which will cause itto agglutinate and will result in higherabsorbance. If increased amount ofcompeting drug is present in the sample, thiswill result in decreased binding of bounddrug by the antibody, resulting in a relativedecrease in particle agglutination. This inturn results in lower absorbance. Theprecise relationship between particleagglutination and concentration of theunlabeled drug in the sample is establishedby measuring the absorbance values ofcalibrators with known concentration of thedrug. The absorbance of unknown samplescan be interpolated from the absorbancevalues of the calibration curve and theconcentration of the drug present in thesample can be calculated. | In particle agglutination assays, the degreeof agglutination (detected by optical methodat 700 nm) is inversely proportional to thequantity of free drug in the reaction well.Hence, if no drug is present in the sample,the antibodies in the QMS® EverolimusAntibody Reagent (R1) will bind only to thebound drug on the particle which will cause itto agglutinate and will result in higherabsorbance.

Precision and Accuracy
Everolimus samples were tested for precision following a CLSI protocol. In the study, the total run %CV was less than or equal to 10.0% which is in agreement with our currently cleared labeling.
Method Comparison
Samples were tested in the QMS® Everolimus Assay and compared to LC/MS. The method comparison exhibited correlated well with LC/MS as follows: y = 1.07x + 0.19, R = 0.97.
Dilution Recovery
Samples were tested to demonstrate linearity throughout the assay range of 2-20 ng/mL. Results demonstrate that the assay performs in a linear fashion which is in agreement with our currently cleared labeling.
Conclusion
As summarized, the modification to the indications for use in the Thermo Scientific QMS® Everolimus Assay is substantially equivalent to the originally cleared product (K100144). Substantial equivalence has been demonstrated through performance testing (Section 18) to verify that the device functions as intended and that design specifications have been satisfied.
