# K. Test Principle:
The Elecsys AMH assay makes use of a sandwich test principle using monoclonal antibodies that are specifically directed against AMH. Endogenous AMH is bound by both a biotinylated monoclonal AMH-specific antibody and a monoclonal AMH-specific antibody labeled with a ruthenium complex to form a sandwich complex. Results are determined via a calibration curve which is instrument-specifically generated by a two-point calibration and a master curve provided via the reagent barcode.

# b. Linearity/assay reportable range:
#### Linearity:
Linearity of the Elecsys AMH Assay were evaluated according to CLSI EP6-A. Three high level samples were diluted with postmenopausal female serum for a total of 15 concentration levels. Samples were assayed in triplicate on the cobas e 411 analyzer. The observed values were graphed against the calculated values and a linear regression was performed. Results are summarized in the table below:
| Sample | Sample range (ng/mL) | Slope | Intercept | Correlation (r) |
|--------|----------------------|--------|-----------|-----------------|
| Set 1 | 0.004 – 27.5 | 1.0091 | 0.0105 | 0.999 |
| Set 2 | 0.004 - 27.4 | 1.0054 | 0.0205 | 0.999 |
| Set 3 | 0.004 - 25.8 | 1.0063 | 0.0013 | 0.999 |
The linear regression results support the Applicant's claimed measuring range (0.03
{5}------------------------------------------------
ng/mL - 23 ng/mL).
## Dilution:
A dilution study was performed by diluting six human samples with Diluent Universal in 1:2 ratio both manually and by the analyzer. The data support the following instruction for use:
Samples with AMH concentrations above the measuring range can be diluted automatically with Diluent Universal 2. Manual dilution can be performed with Diluent Universal 2. The recommended dilution is 1:2 (either automatically by the cobas e analyzer or manually). The concentration of the diluted sample must be > 10 ng/mL. After manual dilution, multiply the result by the dilution factor. After dilution by the analyzer, the cobas e software automatically takes the dilution into account when calculating the sample concentration.
- Traceability, Stability, Expected values (controls, calibrators, or methods): C.
#### Traceability:
The AMH CalSet are traceable to manufacturer's internal reference standards (Master Calibrators), which consist of a panel of well characterized serum reference materials covering the entire measuring range. The Applicant submitted a detailed traceability assurance plan which was reviewed and found to be acceptable. The target values for AMH CalSet are shown below:
| Level | Target Value<br>(ng/mL) | Target Range<br>(ng/mL) |
|--------------|-------------------------|-------------------------|
| Calibrator 1 | <0.1 | <0.1 |
| Calibrator 2 | 8.0 | 7.2-8.8 |
#### Stability:
Shelf life stability studies were performed with assay reagents, calibrators and controls, and demonstrated that they are stable for at least 15 months when stored unopened at 2-8°C. Once opened, the AMH reagents are stable for 12 weeks at 2-8°C and for 8 weeks on board. The lyophilized AMH CalSet and lyophilized PreciControl AMH are for single use only on board. The reconstituted AMH CalCheck 5 is stable for 3 hours on board. The protocols for stability and acceptance criteria were reviewed and found to be adequate.

- a. Clinical sensitivity and specificity:
#### Clinical Studies:
The use of AMH for the assessment of ovarian reserve was investigated in a multicenter, prospective, non-interventional study with N = 856 women presenting at fertility clinics for evaluation. Patient BMI included in the study ranged from 14.76 to 39.99, as shown below:
{9}------------------------------------------------
| BMI | N |
|--------------|-----|
| <18.50 | 29 |
| 18.50-24.99 | 469 |
| 25.00-29.99 | 200 |
| >30.00-39.99 | 158 |
AMH values were correlated to the antral follicle count (AFC) of the women. AFC was determined by transvaginal ultrasonography (TVUS), which measures antral follicles (2-10 mm) of the ovary. Both AFC and AMH were determined on days 2-4 of the same menstrual cycle. Clinical serum samples were collected at 13 geographically diverse sites in the United States, and then tested at 3 laboratory sites in the United States on cobas e 411 analyzers.
Based on the AFC, two groups are defined: AFC ≤ 15 and AFC > 15. Correlation of AMH (using the 1.77 ng/mL cutoff) and AFC is presented in the table below (relationship is shown in both absolute numbers and percentages per AMH group):
| | AFC ≤ 15 | AFC > 15 | N |
|------------------|-----------------|-----------------|-----|
| AMH ≤ 1.77 ng/mL | 280<br>(84.3 %) | 52<br>(15.7 %) | 332 |
| AMH > 1.77 ng/mL | 130<br>(24.8 %) | 394<br>(75.2 %) | 524 |
| N | 410 | 446 | 856 |
The following figure illustrates the Validation Arm AMH results, presented by AFC group/class (AFC < 15 and AFC > 15).
{10}------------------------------------------------
Image /page/10/Figure/0 description: The image shows a boxplot comparing AMH levels in ng/mL for two AFC classes, 0-15 and >15. The sample size for the 0-15 class is N=410, while the sample size for the >15 class is N=446. The AMH levels appear to be higher in the >15 AFC class compared to the 0-15 class, as indicated by the position of the boxes and the median values represented by the '+' symbols.
Positive predictive value (PPV), negative predictive value (NPV), sensitivity, and specificity for predicting AFC > 15 (with 95% confidence intervals in parentheses) observed in the study using the 1.77 ng/mL cutoff are summarized in the following table:
| | Result | 95% CI |
|-------------|--------|--------------|
| PPV | 75.2% | (71.3-78.8%) |
| NPV | 84.3% | (80.0-88.1%) |
| Sensitivity | 88.3% | (85.0-91.2%) |
| Specificity | 68.3% | (63.6-72.8%) |
- b. Other clinical supportive data (when a. is not applicable):
Not applicable.
- 4. Clinical cut-off:
The AMH cutoff, intended to predict an antral follicle count (AFC) >15, is 1.77 ng/mL.
- 5. Expected values/Reference range:
A reference range study was conducted to establish age-dependent reference ranges for AMH in 718 apparently healthy females of reproductive age between 20 and 44 years. Native serum samples were collected and testing was conducted at two sites. The reference range values for different age groups are summarized below:

# O. Benefit/Risk Analysis:
| Summary | |
|----------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Summary of<br>the Benefit(s) | The primary benefit of the Elecsys AMH system is its use in the prediction (in<br>conjunction with other clinical and laboratory findings) of high ovarian<br>reserve. The assessment of ovarian reserve prior to performing controlled<br>ovarian stimulation (COS) can assist in the reduction of risk of patients<br>developing ovarian hyperstimulation syndrome (OHSS) by identifying those<br>patients with a higher OHSS risk (i.e., those with high ovarian reserve levels,<br>which correspond to an antral follicle count (AFC) of >15).<br>The AMH cut-off corresponding to an AFC > 15 was validated with a<br>sensitivity and specificity of 88.3% and 68.3%, respectively. |
| Summary of<br>the Risk(s) | The primary risks to patients through the use of the device are related to the<br>consequences of clinical decisions based on false positive and the more<br>clinically significant false negative results.<br>False positive results may lead to a modification, delay or cancellation before<br>a controlled ovarian stimulation procedure is initiated. Modifications to a<br>stimulation regimen may lead to less oocytes for fertilization. False positive<br>results may result in the need for a repeat procedure and cancelled or delayed<br>stimulation.<br>False negative results may lead to the development of ovarian<br>hyperstimulation syndrome, a potentially life-threatening condition, in<br>patients incorrectly thought to have normal and/or diminished ovarian reserve.<br>However, this risk can be mitigated through appropriate labeling indicating<br>that AMH assay is intended to be used for assessing the ovarian reserve in<br>conjunction with other clinical and laboratory findings before starting any<br>fertility therapy, and should be used in conjunction with Antral Follicle Count.<br>Additional risks to patients and laboratory workers include those that are<br>associated with routine phlebotomy performed as standard practice in a<br>clinical setting. |
| Summary of<br>Other Factors | There are no additional factors to consider. |
| Summary | |
| Conclusions<br>Do the<br>probable<br>benefits<br>outweigh the<br>probable risks? | Given the performance characteristics, applicable general controls, including<br>design controls, and proposed special controls, including labeling<br>mitigations, the probable benefits outweigh the probable risks for this device. |

- a) Identification. An anti-mullerian hormone test system is an in vitro diagnostic device intended to measure anti-mullerian hormone in human serum and plasma. An antimullerian hormone test system is intended to be used as an aid for assessing ovarian reserve in women.
- b) Classification. Class II (special controls). An anti-mullerian hormone test system must comply with the following special controls:
- 1) Premarket notification submissions must include the following information:
- An adequate traceability plan to minimize the risk of drift in anti-1. mullerian hormone test system results over time.
- ii. Detailed documentation of a prospective clinical study to demonstrate clinical performance or, if appropriate, results from an equivalent sample set. This detailed documentation must include the following information:
- Results must demonstrate adequate clinical performance relative to a. a well-accepted comparator.
- b. Clinical sample results must demonstrate consistency of device output throughout the device measuring range that is appropriate for the intended use population.
- c. Clinical study documentation must include the original study protocol (including predefined statistical analysis plan), study report documenting support for the proposed indications for use(s), and results of all statistical analyses.
- iii. Reference intervals generated by testing an adequate number of samples from apparently healthy normal individuals in the intended use population.
{14}------------------------------------------------
- 2) Your 809.10(b) compliant labeling must include a warning statement that the device is intended to be used for assessing the ovarian reserve in conjunction with other clinical and laboratory findings before starting any fertility therapy, and that the device should be used in conjunction with the Antral Follicle Count.
