Dear Huseyin Firat:

The Center for Devices and Radiological Health (CDRH) of the Food and Drug Administration (FDA) has completed its review of your De Novo request for classification of the APO-Easy Genotyping kit, a prescription device with the following indications for use:

The APO-Easy Genotyping kit is a qualitative polymerase chain reaction (PCR) test intended for the detection of two single nucleotide polymorphisms (SNPs), rs429358 and rs7412, in the APOE gene using genomic DNA extracted from human EDTA whole blood. The APOE genotype information provided by the test is used with other laboratory and clinical information to aid in the evaluation of the risk of developing late-onset Alzheimer's Disease (AD) in patients presenting with cognitive impairment and/or with predisposing risk factors, who are being evaluated for AD and other causes of cognitive decline.

The APO-Easy Genotyping kit is not a screening or diagnostic test and does not determine the person's overall risk of developing late-onset AD. It is not intended to replace any clinical and diagnostic examinations.

FDA concludes that this device should be classified into Class II. This order, therefore, classifies the APO-Easy Genotyping kit, and substantially equivalent devices of this generic type, into Class II under the generic name neurologic disease predisposition risk assessment system.

FDA identifies this generic type of device as:

Neurologic disease predisposition risk assessment system. A neurologic disease predisposition risk assessment system is a prescription in vitro diagnostic device intended to detect or measure DNA, RNA, or protein variants in human specimens. The measurements aid in the evaluation of the risk of developing a neurologic disease in patients presenting with symptoms and/or with disease-associated risk factors to aid in patient management, in conjunction with other laboratory and clinical information.

Section 513(f)(2) of the Food, Drug and Cosmetic Act (the FD&C Act) was amended by section 607 of the Food and Drug Administration Safety and Innovation Act (FDASIA) on July 9, 2012. This law provides two options for De Novo classification. First, any person who receives a "not substantially equivalent" (NSE) determination in response to a 510(k) for a device that has not been previously classified under the Act may request FDA to make a risk-based classification of the device under section 513(a)(1) of the Act. On December 13, 2016, the 21st Century Cures Act removed a requirement that a De Novo request be submitted within 30 days of receiving an NSE determination. Alternatively, any person who determines that there is no legally marketed device upon which to base a determination of substantial equivalence may request FDA to make a risk-based classification of the device under section 513(a)(1) of the Act without first submitting a 510(k). FDA shall, within 120 days of receiving such a request, classify the device. This classification shall be the initial classification of the device. Within 30 days after the issuance of an order classifying the device, FDA must publish a notice in the Federal Register announcing the classification.

On June 21, 2024, FDA received your De Novo requesting classification of the APO-Easy Genotyping kit. The request was submitted under section 513(f)(2) of the FD&C Act. In order to classify the APO-Easy Genotyping kit into class I or II, it is necessary that the proposed class have sufficient regulatory controls to provide reasonable assurance of the safety and effectiveness of the device for its intended use. After review of the information submitted in the De Novo request, FDA has determined that, for the previously stated indications for use, the APO-Easy Genotyping kit can be classified in class II with the establishment of special controls for class II. FDA believes that class II (special) controls provide reasonable assurance of the safety and effectiveness of the device type. The identified risks and mitigation measures associated with the device type are summarized in the following table:

| Risks to Health | Mitigation Measures |
| --- | --- |
| Incorrect test results leading to false positive or false negative results. | Design verification and validation, including certain analytical and clinical studies.
Certain labeling information, including limiting statements. |
| Inappropriate interpretation of test results. | Design verification and validation, including certain analytical and clinical studies.
Certain labeling information, including limiting statements. |

In combination with the general controls of the FD&C Act, the neurologic disease predisposition risk assessment system is subject to the following special controls:

(1) Design verification and validation must include:

(i) Device performance data demonstrating appropriate analytical performance for the intended use specimen type(s), including precision and reproducibility, detection limit of the device, linearity, assay interference, cross-reactivity, specimen and reagent stability, and analytical accuracy studies, as determined to be appropriate by FDA. For devices that are intended to measure multiple genetic or protein variants, the performance data must demonstrate the analytical performance of the device for each individual variant and for any output(s) that combine multiple variants.

(ii) Clinical performance data or evidence to support the intended use of the device. The neurological disease risk assessment must be representative of the intended use population and include well-established scientific literature, clinical performance data, or both, as determined to be appropriate by FDA.

(2) The labeling must include:

(i) Limiting statements that the test is not a screening or diagnostic test and that the test does not determine the patient's overall risk of developing the specified neurologic disease.

(ii) An appropriate summary, as determined by FDA, of the performance data or evidence that relate to all design verification and validation special controls, as well as a description of the detection targets.

Although this letter refers to your product as a device, please be aware that some granted products may instead be combination products. If you have questions on whether your product is a combination product, contact [e-mail].

Section 510(m) of the FD&C Act provides that FDA may exempt a class II device from the premarket notification requirements under section 510(k) of the FD&C Act, if FDA determines that premarket notification is not necessary to provide reasonable assurance of the safety and effectiveness of the device type. FDA has determined premarket notification is necessary to provide reasonable assurance of the safety and effectiveness of the device type and, therefore, the device is not exempt from the premarket notification requirements of the FD&C Act. Thus, persons who intend to market this device type must submit a premarket notification containing information on the neurologic disease predisposition risk assessment system they intend to market prior to marketing the device.

Please be advised that FDA's decision to grant this De Novo request does not mean that FDA has made a determination that your device complies with other requirements of the FD&C Act or any Federal statutes and regulations administered by other Federal agencies.
