The ARCHITECT HE4 assay is a chemiluminescent microparticle immunoassay (CMIA) for the quantitative determination of HE4 antigen in human serum. The assay is to be used as an aid in monitoring recurrence or progressive disease in patients with epithelial ovarian cancer. Serial testing for patient HE4 assay values should be used in conjunction with other clinical methods used for monitoring ovarian cancer.
The ARCHITECT HE4 Calibrators are for the calibration of the ARCHITECT i System when used for the quantitative determination of HE4 antigen in human serum.
The ARCHITECT HE4 Controls are used for the verification of the accuracy and precision of the ARCHITECT i System when used for the quantitative determination of HE4 antigen in human serum.
The ARCHITECT HE4 assay is a two-step immunoassay for the quantitative determination of HE4 antigen in human serum using CMIA technology with flexible assay protocols, referred to as Chemiflex.
In the first step, sample and 2H5 anti-HE4 coated paramagnetic microparticles are combined. HE4 antigen present in the sample binds to the anti-HE4 coated microparticles. After washing, 3D8 anti-HE4 acridinium-labeled conjugate is added to create a reaction mixture in the second step. Following another wash cycle, pre-trigger and trigger solutions are added to the reaction mixture. The resulting chemiluminescent reaction is measured as relative light units (RLUs).
A direct relationship exists between the amount of HE4 antigen in the sample and the RLUs detected by the ARCHITECT i System optics.

2. Sample Size Used for the Test Set and Data Provenance
- Method Comparison: 193 serum specimens. Data provenance is not explicitly stated (e.g., country of origin) but implies a clinical laboratory setting for comparison with a commercially available EIA. The study compared the new device against an existing, commercially available HE4 EIA.
- Precision: Not explicitly an independent "test set" in the common sense, but involved assays of controls and panels. Performed at Fujirebio Diagnostics, Inc. and two external sites.
- Linearity: Samples prepared by mixing serum panels.
- Sensitivity (LoB, LoD, LoQ): One zero-level HE4 sample and four low-level HE4 samples.
- Specificity: Not explicitly a patient "test set". Tumor markers were prepared with ARCHITECT HE4 Calibrator A.
- Interference: Sera containing therapeutic agents and endogenous substances (concentration details provided), and clinical specimens positive for HAMA (6 specimens) and Rheumatoid Factor (6 specimens).
- Monitoring of Disease Status: 76 patients, resulting in 430 pairs of observations (serial samples, average 6.7 observations per patient). Data provenance is not explicitly stated (e.g., country of origin, retrospective/prospective). This appears to be a retrospective analysis of serial samples.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
The document does not explicitly state the number or qualifications of experts used to establish ground truth for any of the studies, particularly for clinical disease progression. For the "Monitoring of Disease Status" study, "changes in disease status" are mentioned, implying a clinical assessment, but the method for determining disease progression or lack thereof (e.g., imaging, pathology, clinical criteria) and who made these assessments is not detailed.
4. Adjudication Method for the Test Set
The document does not describe an adjudication method for establishing ground truth for any of the test sets. For the "Monitoring of Disease Status" study, while "changes in disease status" were used as a reference, the process by which this status was determined (e.g., consensus, single expert, independent review) is not provided.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
There is no mention of a multi-reader multi-case (MRMC) comparative effectiveness study in the provided text. The device is an immunoassay for quantitative determination of a biomarker, not an imaging device or diagnostic tool that typically involves human interpretation. Therefore, a study comparing human readers with and without AI assistance is not applicable here.
6. Standalone Performance Study
The reported performance characteristics (Method Comparison, Precision, Linearity, Sensitivity, Specificity, Interference) are all standalone (algorithm only) performance studies of the ARCHITECT HE4 assay. These evaluate the analytical performance of the device without human interpretation in the loop, focusing on its ability to accurately measure HE4 antigen levels. The "Monitoring of Disease status" study also represents the standalone performance of the assay in classifying disease changes based on a defined threshold.
7. Type of Ground Truth Used
- Method Comparison: The ground truth was the results from a "commercially available HE4 EIA" (the predicate device, HE4 EIA K072939).
- Precision, Linearity, Sensitivity, Specificity, Interference: The ground truth was based on established analytical standards, spiked samples, or reference materials with known concentrations. For example, "zero-level HE4 sample," "four low-level HE4 samples," "tumor markers prepared with ARCHITECT HE4 Calibrator A," and "sera containing therapeutic agents and endogenous substances at indicated interferent concentrations."
- Monitoring of Disease Status: The ground truth was "changes in disease status" in patients with epithelial ovarian cancer. While not explicitly defined, this would typically involve a combination of clinical assessments, imaging (e.g., CT scans, MRI), and potentially other tumor markers or biopsy results, as determined by clinicians.
8. Sample Size for the Training Set
The document does not specify a training set for the ARCHITECT HE4 assay. This is typical for an immunoassay that operates based on a physically determined chemical reaction and a calibration curve, rather than a machine learning algorithm that requires a separate training phase. The device is calibrated using ARCHITECT HE4 Calibrators, which serve a similar function to a training set by defining the assay's response curve, but are distinct from data used to train a predictive algorithm.
9. How the Ground Truth for the Training Set Was Established
As no explicit "training set" in the machine learning sense is described, this question is not directly applicable. For the calibrators (which functionally serve to "train" or calibrate the instrument), their values would be established through a rigorous process of manufacturing, characterization, and validation against reference standards by the manufacturer (Fujirebio Diagnostics, Inc.), ensuring accurate assignment of HE4 concentrations to each calibrator level.

Performance Characteristics
Method Comparison:
The ARCHITECT HE4 assay is designed to have a slope of 1.0 ± 0.1 and a correlation coefficient (r) of ≥ 0.90 for serum specimens when compared to a commercially available HE4 EIA. One hundred and ninety-three serum specimens were tested using the ARCHITECT HE4 assay and the HE4 EIA. The data are summarized in the following table.
| RegressionMethod | n | Slope(95% CIa) | Intercept(95% CIa) | CorrelationCoefficient |
|---|---|---|---|---|
| Passing-Bablokb | 193 | 0.96(0.93 to 1.00) | -2.51(-3.96 to -0.73) | 0.97 |
ARCHITECT HE4 vs. HE4 EIA
ARCHITECT HE4 Specimen Range = 20.3 to 918.7 pmol/L
HE4 EIA Specimen Range = 21.9 to 762.3 pmol/L
a CI = Confidence Interval
b A linear regression method with no special assumptions regarding the distribution of the samples and measurement errors.
Precision:
The ARCHITECT HE4 assay is designed to have an imprecision of ≤ 10% total CV. A study was performed based on guidance from the National Committee for Clinical Laboratory standards (NCCLS) document EP5-A2. Testing was conducted at Fujirebio Diagnostics, Inc. using one lot of reagents, calibrators, and controls and at two external sites using two lots of reagents, calibrators, and controls. Three levels of controls and panels were assayed on one instrument per site in replicates of two at two separate times per day for 20 different days. Each instrument used a single calibration curve throughout the study.
Linearity:
The ARCHITECT HE4 assay is designed to be linear across the measurement range of 20.0 to 1500.0 pmol/L. Samples were prepared by mixing serum panels with diluted wash buffer and tested with the ARCHITECT HE4 assay. Based on a study performed by guidance from the NCCLS document EP6-A, the ARCHITECT HE4 assay demonstrated linearity from 20.0 to 1500.0 pmol/L.
Sensitivity (LoB, LoD, LoQ):
The ARCHITECT HE4 assay is designed to have a Limit of Detection (LoD) of ≤ 15 pmoИL and a Limit of Quantitation (LoQ) of ≤ 20 pmol/L. The LoQ is defined as the lowest amount of analyte in a sample that can be accurately quantitated with a total allowable error of ≤ 30%. A study was performed based on guidance from the NCCLS document EP17-A with one zero-level HE4 sample and four low-level HE4 samples.
The samples were tested in a minimum of five replicates once per day for three different days using three reagent lots and two instruments. The Limit of Blank (LoB) was 0.1 pmo//L, the LoD was 0.2 pmol/L, and the LoQ was 0.2 pmol/L.

Monitoring of Disease status in Patients Diagnosed with Epithelial Ovarian Cancer
A study was performed using the ARCHITECT HE4 assay as an aid in monitoring of disease status in epithelial ovarian cancer patients by assessing changes in HE4 levels in serial serum samples from 76 patients compared to changes in disease status. A study involving a total of 430 pairs of observations was undertaken with an average number of 6.7 observations per patient. A positive change in HE4 was defined as an increase in the value that was at least 14% greater than the previous value of the test. This level of change takes into account the analytical variability of the assay. The data are summarized in the following table.
| Change in Disease State per Sequentlal Pair | |||||
|---|---|---|---|---|---|
| HE4 Concentration Change | NoProgression | Progression | Total | ||
| less than 14% | 261 | 46 | 307 | ||
| greater than or equal to 14% | 70 | 53 | 123 | ||
| Total | 331 | 99 | 430 |
Fifty-four percent (54%) or 53/99 sequential pairs from patients with disease progression demonstrated an HE4 concentration increase of greater than or equal to 14%. Seventy-nine percent (79%) or 261/331 sequential pairs for patients with no disease progression demonstrated an HE4 concentration of less than 14%. The total concordance for this study was seventy-three percent (73%) or 314/430. Clinicians may wish to use other percent changes in HE4 concentration to reflect their preferences in the trade-off between sensitivity and specificity. The following table shows the resulting sensitivities and specificities of the ARCHITECT HE4 assay at various percent changes in ARCHITECT HE4 assay concentrations, together with the positive predictive values (PPV) and negative predictive values (NPV) for the population tested (99 sequential pairs from patients with disease progression and 331 sequential pairs from patients with no progression.)
| Percent (%)Change in HE4 | Sensitivity a(%) | Specificity b(%) | PPV c(%) | NPV d(%) |
