Intended Use

The NOVEOS Specific IgE Assay is an in vitro quantitative assay for the measurement of allergen specific IgE in human serum. NOVEOS Specific IgE Assay is to be used with the NOVEOS Immunoassay Analyzer. It is intended for use as an in vitro diagnostic aid in the clinical diagnosis of IgE mediated allergic disorders in conjunction with other clinical findings and is to be used in clinical laboratories.

Device Story

The NOVEOS Specific IgE Assay is an in vitro diagnostic test performed on the NOVEOS Immunoassay Analyzer in clinical laboratories. It uses human serum samples to detect allergen-specific IgE. The assay employs fluorescent-labeled, streptavidin-coated magnetic microparticles incubated with a biotinylated allergenic capture reagent, the patient sample, and a horseradish peroxidase-conjugated monoclonal anti-human IgE antibody. After washing, an enzyme substrate is added to generate a chemiluminescent signal proportional to the IgE concentration. Results are calculated against a standard curve traceable to WHO reference reagent 11/234. Healthcare providers use these quantitative results, alongside clinical history and other findings, to diagnose IgE-mediated allergic disorders. The device provides a standardized, automated method for allergy testing, potentially improving diagnostic accuracy and efficiency compared to manual or less sensitive methods.

Clinical Evidence

Clinical performance was evaluated by comparing NOVEOS sIgE results to allergic status (confirmed by skin-prick testing and clinical history) in 200 samples for Cat Dander (E001) and 188 samples for Timothy Grass (G006). For E001, clinical sensitivity was 75.7% and specificity was 100%. For G006, clinical sensitivity was 76.2% and specificity was 99.2%. Method comparison studies against the predicate ImmunoCAP showed high agreement (PPA 91.8% for E001; 86.4% for G006). Analytical performance included imprecision (total CV <12%), linearity (R2 >0.99), and interference testing showing <15% interference for common substances.

Regulatory Classification

Identification

A radioallergosorbent immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the allergen antibodies (antibodies which cause an allergic reaction) specific for a given allergen. Measurement of specific allergen antibodies may aid in the diagnosis of asthma, allergies, and other pulmonary disorders.

The NOVEOS Immunoassay Analyzer is a high-throughput, highly automated immunoassay platform that employs magnetic microbeads as the solid phase. The immunoassay reaction takes place in individual reaction chambers in the reaction rotor, with other rotors containing patient samples and reagents. Liquids are moved by robotic pipettors. The reaction is quantitated by a combination of chemiluminescence and fluorescence measurements compared to a calibration curve, all performed by the analyzer with the NOVEOS software.

## B Principle of Operation:

The NOVEOS specific IgE (sIgE) Assay is an immunometric, chemiluminescent assay for the quantitative determination of IgE of known specificity in human serum samples. Magnetic beads coated with streptavidin and fluorescent dye are incubated with a biotinylated allergen that binds to the streptavidin molecule on the surface of the beads. The beads are collected by use of a magnetic field to remove the liquid, and then undergo a wash step to remove unbound biotinylated allergen prior to incubation with the sample. If present in the sample, sIgE binds to the captured biotinylated allergen. After incubation, the beads are washed and subsequently incubated with an HRP-labeled anti-IgE monoclonal antibody (Conjugate IgE) to form an antibody-conjugate complex that is bound to the captured biotinylated allergen. After washing away the non-bound conjugate, a chemiluminescent substrate is added to the assay mixture resulting in light generation in proportion to the amount of antibody-conjugate that has been bound to the beads. The fluorescence is used to correct for any bead loss during the assay, and the (corrected) chemiluminescence is compared to a calibration curve to provide quantification of bound sIgE. The higher the value of chemilumiscent signal detected by the instrument, the higher the amount of sIgE detected in the sample tested.

iii) Site-to-site reproducibility:

Reproducibility of the NOVEOS sIgE Assay, E001 and the NOVEOS sIgE Assay, G006 was evaluated by testing two separate six-member panels, one consisting of one negative and three positive human serum samples for E001 plus two controls and another consisting of one positive and three negative serum samples for G006 plus two controls, at three sites using the same lot of reagent. Each sample was tested in five replicates per run, one run per day for five days on one NOVEOS Immunoassay Analyzer at each site (for a total of 75 measurements per sample at all three sites). The results are summarized in the following tables:

2. Linearity:

Linearity of each NOVEOS sIgE Assay was evaluated following CLSI guideline EP6-A by preparing three sets of dilution panel. Three positive serum samples (low, medium and high level) were each serially diluted in a two-fold scheme with a negative serum pool generating at least five consecutive dilutions. Each diluted sample was tested in replicates of five and each neat sample was tested in replicates of 15, all within one assay run using one reagent lot on one NOVEOS Immunoassay Analyzer. Results of the replicates for all three samples were analyzed for linearity. Regression statistics comparing the observed results (y) to expected results (x) of all samples in each and all three dilution panels are presented in the tables below.

The data summarized in the tables above support linearity throughout the claimed measuring range from 0.17 kU/L to 100 kU/L for both the NOVEOS sIgE Assay, E001 and NOVEOS sIgE Assay, G006.

## 3. Analytical Specificity/Interference:

### a) Inhibition study:

Immunological specificity of E001 (Cat Dander, *Felis domesticus*) and G006 (Timothy Grass, *Phleum pretense*) allergens was verified through competitive inhibition according to CLSI guideline I/LA20-A3. A positive sample with specific IgE concentration of ~7.6 kU/L for E001 and ~0.6 kU/L for G006 was used in the inhibition studies. The allergen solution (inhibitor) was diluted into the positive serum sample to achieve a starting concentration of 15 µg/mL for E001 and 50 µg/mL for G006. The sample solution was serially diluted five times in two-fold increments and each diluted sample was evaluated for dose-dependent inhibition in five replicates with one lot of reagent. The results of the dose-dependent inhibition study showed that &gt;50% inhibition was achieved with E001 and G006 at a final inhibitor concentration of 15 µg/mL and 25 µg/mL, respectively.

For the NOVEOS sIgE Assay, E001, the related allergen E006 (guinea pig epithelia, *Cavia porcellus*), and the unrelated allergens, G013 (velvet grass, *Holcus lanatus*), W011 (Russian thistle, *Salsola kali*) and M004 (*Mucor circinelloides f. lusitanicus*) were tested as potential inhibitors for at a final concentration of at least ten times the concentration of E001 at which &gt;50% inhibition was achieved. All allergen inhibitors were spiked into the positive serum sample at a 1:1 dilution and evaluated with three lots of NOVEOS sIgE Assay, E001. The results of the single-dose inhibition studies using one related allergen (E006) and three unrelated allergens (G013, W011 and M004) did not show inhibition at a test concentration of 150 µg/mL for the related allergen and 150 µg/mL for the three unrelated allergens. The inhibition studies indicate that the NOVEOS sIgE Assay, E001 contains the immunologically relevant allergen.

K200825 - Page 9 of 16

{9}

For the NOVEOS sIgE Assay, G006, the related allergen G202 (cultivated corn, Zia mays), and the unrelated allergens, W043 (common sagebrush, Artemisia tridentata), F018 (brazil nut, Bertholletia excelsa) and M004 (Mucor circinelloides f. lusitanicus) were tested as potential inhibitors at a final concentration of at least ten times the concentration of G006 at which &gt;50% inhibition was achieved. All allergen inhibitors were spiked into the positive serum sample at a 1:1 dilution and evaluated with three lots of NOVEOS sIgE Assay, G006. The results of the single-dose inhibition studies using one related allergen (G202) and three unrelated allergens (W043, F018 and M004) did not show inhibition at a test concentration of 250 µg/mL for the related allergen and 250 µg/mL for the three unrelated allergens. The inhibition studies indicate that the NOVEOS sIgE Assay, G006 contains the immunologically relevant allergen.

b) Interference:

(1) Endogenous Substance Interference:

The effect of the presence of elevated level of human albumin, hemoglobin, triglyceride, conjugated bilirubin, unconjugated bilirubin, and rheumatoid factor in serum samples was evaluated by testing three (one negative, one near the cut-off and one positive) serum sample pools spiked with varying levels of each interferent and analyzed in 12 replicates in one assay run with three lots of each NOVEOS sIgE Assay. The % recovery for each sample spiked with the potential interfering substance was calculated by comparing its result to that of the corresponding reference sample spiked with an equal volume of the solvent without the interfering substance. No interference was noted for samples containing human serum albumin up to 120 g/L, hemoglobin up to 200 mg/dL, intralipid up to 3000 mg/dL, conjugated bilirubin up to 30 mg/dL, unconjugated bilirubin up to 20 mg/dL, and rheumatoid factor up to 513 IU/mL.

(2) Exogenous Substance Interference:

The same protocol used in the endogenous substance interference study was used to evaluate potentially interfering exogenous substances. No interference was noted for samples containing biotin at a concentration of 3500 ng/mL, diphenhydramine at 19.6 µmol/L, methylprednisolone at 1000 ng/mL, omalizumab at 0.12 mg/mL and ranitidine at 19.1 µmol/L.

c) Cross-reactivity:

The potential cross-reactivity of non-IgE (IgA, IgD, IgG, and IgM) to the NOVEOS sIgE Assay, E001 and NOVEOS sIgE Assay, G006 was evaluated by testing two separate panel, one consisting of three human serum samples (one negative and two positives including one near 0.35 kU/L for E001) and another consisting of five human serum samples (one negative and four positives including one near 0.35 kU/L for G006). Each serum sample was spiked with the immunoglobulin stock solutions containing IgA, IgG, and IgM (IgGAM) at 76.86 mg/mL and IgD at 77.25 mg/mL. The control samples were prepared by adding a solvent to mimic the IgGAM and IgD spiked volumes. Test and control samples were analyzed in replicates of three in one assay run with one lot of the reagent. The % recovery was calculated by comparing measurements of the test and

K200825 - Page 10 of 16

{10}

control samples. No cross reactivity was noted up to 14.86 mg/mL for IgGAM and up to 0.173 mg/mL for IgD.

## 4. Assay Reportable Range:

The claimed measuring range is from 0.17 kU/L to 100 kU/L.

## 5. Traceability, Stability, Expected Values (Controls, Calibrators, or Methods):

a) Traceability:

The IgE calibrators are traceable to the World Health Organization (WHO) third International Standard 11/234 of Human Serum Immunoglobulin E.

b) Kit Stability:

Shelf life stability: Both an ongoing real-time stability study and an accelerated stability study were performed in accordance with CLSI EP25-A using three lots of the NOVEOS E001 Capture Reagent and three lots of the NOVEOS G006 Capture Reagent. The accelerated stability data support the manufacturer's claim of 24-month unopened shelf-life stability for both the NOVEOS E001 Capture Reagent and NOVEOS G006 Capture Reagent. The real-time stability study is on-going and available data supports 16 months unopened shelf-life stability for both the NOVEOS E001 Capture Reagent and NOVEOS G006 Capture Reagent when stored at 2–8 °C per the manufacturer's instruction for use. All other reagents required to perform specific IgE testing on the NOVEOS system are not allergen specific and the shelf-life stability of these reagents has been previously established per K182479, with the exception of the Fluo Beads reagent which has an extended shelf-life stability of up to 24 months based on the real-time stability data per K191510. The claimed shelf-life for individual assay components is listed in the table below:

| | | Shelf-life Stability (2–8 °C) |

6. Detection Limit:

The limit of blank (LoB), limit of detection (LoD), and limit of Quantitation (LoQ) of the NOVEOS sIgE Assay, E001 and the NOVEOS sIgE Assay, G006 on the NOVEOS Immunoassay Analyzer were determined according to CLSI guideline EP17-A2.

LoB was determined by testing five IgE-free human serum samples in two replicates per run, one run per day, for six days using three lots of each NOVEOS sIgE Assay. The runs were spread out on three different NOVEOS Immunoassay Analyzers. The LoB was estimated as the 95th percentile of 60 measurements for each of the lots tested.

LoD was determined using five serum samples with low IgE concentrations with the NOVEOS sIgE Assay, E001 and six serum samples with low IgE concentrations with the NOVEOS sIgE Assay, G006. Each sample was tested in replicates of 10 replicates per run, one run per day, for six days using three lots of each NOVEOS sIgE Assay. The runs were spread out on three different NOVEOS Immunoassay Analyzers. The LoD was determined for each lot based on 300 measurements for E001 or 360 measurements for G006 as the mean concentration of the lowest sample with 95% or more of its replicates recovering above the LoB.

LoQ was determined as functional sensitivity using a set of five samples with low IgE concentrations. Each sample was tested in duplicates per run, two runs per day for 20 days with three lots of each NOVEOS sIgE Assay on one instrument for a total of 80 data points per sample per reagent lot. The LoQ is defined as the mean value of the sample which fulfills the specification for the total within-laboratory imprecision (&lt;20%CV).

K200825 - Page 12 of 16

The claimed LoB, LoD, and LoQ are based on the highest value obtained from the lots tested and are summarized in the table below.

| | LoB | LoD | LoQ |
| --- | --- | --- | --- |
| NOVEOS sIgE Assay, E001 | 0.02 kU/L | 0.06 kU/L | 0.14 kU/L |

# 8. Accuracy (Instrument):

Not applicable

# 9. Carry-Over:

Evaluation of instrument carryover was conducted using one lot of reagent of each NOVEOS sIgE Assay on three NOVEOS Immunoassay Analyzers. The carryover assessment is based on five cycle counts per instrument. Pooled high-level patient samples with sIgE concentrations ranging from 99.1 to $100.0\mathrm{kU / L}$ for E001 and from 81.2 to 89.8 for G006 were aliquoted into five tubes and the pooled low-patient samples with sIgE concentrations of 0.04 and $0.05\mathrm{kU / L}$ for E001 and of 0.05 and $0.06\mathrm{kU / L}$ for G006, were aliquoted into 25 tubes. Each cycle consists of one high sample test followed by five low sample tests against the E001 or G006 capture reagent. Low Sample 1 following High Sample is denoted as "possibly affected" which has the highest chance of potential carryover thus leading to signal change $&gt;0.10\mathrm{kU / L}$ . Low Samples 3-5 is denoted as "very probably unaffected" and therefore should not have elevated $\mathrm{kU / L}$ signal. Carryover assessment is done by measuring the change $(\Delta)$ of [mean concentration of Low Sample 1] and [mean concentration of Low Samples 3-5]. The results are summarized in the tables below:

| NOVEOS sIgE Assay, E001 | | | | |
| --- | --- | --- | --- | --- |

C Clinical Studies:

1. Clinical Sensitivity/ Specificity:

To demonstrate the clinical performance of each NOVEOS sIgE Assay, test results of the clinical samples from atopic and healthy, non-atopic donors evaluated in the method comparison study were compared to a clinical diagnosis of allergy. The atopic donors with a clinical history of allergy-like symptoms were identified as positive by skin prick testing (SPT) and clinical history; and the non-atopic donors with no reported allergy. Results are expressed as positive when a sample with a sIgE value is greater than or equal to 0.35 kU/L or negative when a sample with a sIgE value is less than 0.35 kU/L. The clinical sensitivity and specificity in this study cohort are summarized in the following tables:
