The ADDNOX is indicated for the treatment of pediatric Attention Deficit Hyperactivity Disorder (ADHD) as a monotherapy in patients ages 7 through 12 years old who are not currently taking prescription ADHD medications.
The ADDNOX is intended for patient treatment by prescription only and for use at home under the supervision of a caregiver during periods of sleep.
The ADDNOX is a transcutaneous electrical trigeminal nerve stimulator for Attention Deficit Hyperactivity Disorder. It is a prescription device that stimulates transcutaneously or percutaneously through electrodes placed on the forehead.
The ADDNOX is intended for patient treatment by prescription only and for use at home under the supervision of a caregiver during periods of sleep.
The provided text describes a 510(k) premarket notification for the ADDNOX device, a transcutaneous electrical nerve stimulator for Attention Deficit Hyperactivity Disorder (ADHD). However, it explicitly states:
"No clinical testing was performed on the device."
This means that the submission does not include a study demonstrating device performance against specific acceptance criteria. The clearance for ADDNOX is based on its substantial equivalence to a legally marketed predicate device (SMILE) and non-clinical data (biocompatibility, electrical safety, performance, and software tests).
Therefore, I cannot fulfill your request to describe acceptance criteria and a study proving the device meets them, nor can I provide information about sample sizes, expert involvement, adjudication methods, MRMC studies, standalone performance, or ground truth establishment for a clinical study, as these were not part of this 510(k) submission.
The document focuses on demonstrating that the ADDNOX has similar technological characteristics and performs as safely and effectively as the predicate device through non-clinical testing and comparison.

Dear Dahee Kim:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).
{1}------------------------------------------------
Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30, Design controls; 21 CFR 820.90, Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the OS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.
All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-devices/device-advicecomprehensive-regulatory-assistance/unique-device-identification-system-udi-system.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.

4. SUBJECT DEVICE DESCRIPTION
The ADDNOX is a transcutaneous electrical trigeminal nerve stimulator for Attention Deficit Hyperactivity Disorder. It is a prescription device that stimulates transcutaneously or percutaneously through electrodes placed on the forehead.
The ADDNOX is intended for patient treatment by prescription only and for use at home under the supervision of a caregiver during periods of sleep.
4.1 Principle of Operation
The ADDNOX treatment protocol is administered each night for 7-9 hours while the patient is sleeping. The device is designed to provide non-invasive electrical stimulation of the trigeminal nerve. The trigeminal nerve is the largest cranial nerve and has three major sensory divisions of the face, all of which are bilateral.
The trigeminal nerve provides a direct connection to multiple brain structures implicated in ADHD and other neurologic and neuropsychiatric disorders.
The ADDNOX treatment protocol has proven efficacy in alleviating ADHD symptoms with minimum risk.

10. CONCLUSION
When comparing substantial equivalence between the subject device and the predicate device, similarities exist in various aspects, including general information, technical details, and material details. Although some differences exist, the safety and performance test reports support the safety and effectiveness of the subject device. Therefore, we conclude that the subject device is substantially equivalent to the predicate device.
