The summary describes data collection, processing, and display, but does not mention any AI or ML algorithms for analysis or interpretation of the data. The "Mentions AI, DNN, or ML" section also explicitly states "Not Found".
No
The device is described as logging, tracking, and trending physiological and behavioral metrics, and measuring medication adherence, but not as providing treatment or therapy.
No
The device is intended to log, track, and trend intake times and measure medication adherence, as well as collect physiological and behavioral metrics for clinical and research applications. It does not state that it provides a diagnosis for any condition.
No
The device description explicitly states that the Otsuka Digital Feedback Device-RW consists of three components: a wearable sensor, an ingestible sensor accessory, and software. The performance studies also mention firmware verification, mechanical verification, and electrical verification, indicating hardware components are part of the device.
Based on the provided text, the Otsuka Digital Feedback Device-RW is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for diagnostic purposes.
- Device Function: The Otsuka Digital Feedback Device-RW collects physiological and behavioral metrics directly from the body (heart rate, activity, body angle) and tracks the ingestion of a sensor. It does not analyze specimens taken from the body.
- Intended Use: The intended use is to log, track, and trend intake times (especially for medication adherence) and enable unattended data collection for clinical and research applications. This is focused on monitoring and data collection, not on diagnosing a disease or condition through the analysis of bodily specimens.
Therefore, the device's function and intended use fall outside the scope of an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The Otsuka Digital Feedback Device-RW consists of a miniaturized, wearable sensor for ambulatory recording of physiological and behavioral metrics such as heart rate, activity, body angle relative to gravity (body position), and timestamped patient-logged events, including events signaled by the co-incidence with, or co-ingestible sensor accessory. When the ingestible sensor is ingested, the Otsuka Digital Feedback Device-RW is intended to log, track and trend intake times. When co-ingested with medication, the tracking of intake times may be used as an aid to measure medication adherence. The Otsuka Digital Feedback Device-RW may instance where quantifiable analysis of event-associated physiological and behavioral metrics is desirable, and enables unattended data collection for clinical and research applications.

Device Description
The Otsuka Digital Feedback Device-RW consists of three components: a wearable sensor, an ingestible sensor accessory, and software that aggregates, processes and enables display of data collected by the sensors.
The wearable sensor is a body-worn sensor (also called the patch) that collects physiological and behavioral metrics such as heart rate, activity, body angle, and time-stamped patient-logged events, including events signaled by the co-incidence with, or co-ingestion with, the ingestible sensor accessory. The wearable sensor in the Otsuka Digital Feedback Device-RW is a 2-component patch known as the RW2 wearable sensor or RW2 patch.
The ingestible sensor is embedded inside an inactive tablet (the pill or sensor-enabled pill) for ease of handling and swallowing. After the ingestible sensor reaches the stomach, it activates and communicates its presence with a unique identifier (ID) to the wearable sensor. When the ingestible sensor is co-ingested with medication, the Otsuka Digital Feedback Device-RW is intended to log, track and trend medicine intake times to measure medication adherence.
The software on a general computing device (eg, mobile device) receives the data from the body-worn sensor or patch for further processing and analysis of the behavioral and physiological metrics. The processed data is then sent to the user interface (UI) for display as well as being saved in a local record database for storage.
For purposes of this 510(k), the changes from the predicate device to the device subject of this 510(k) are the wearable sensor and the software for the UI display. The ingestible sensor remains the same from the predicate device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Risk evaluations and verification and validation testing were conducted for each feature that differed from the predicate devices, Proteus Digital Health Feedback Device (K150494) and Proteus Patch, Proteus Ingestible Sensor (K133263), to the Otsuka Digital Feedback Device-RW. The results demonstrate that the acceptance criteria for firmware verification, mechanical verification, electrical verification, biocompatibility evaluation, and system verification testing were met.
Clinical studies were conducted to support the expanded wear location of the patch to include the entire front abdomen. However, new clinical studies were not performed to support the changes proposed in this submission.

Dear Nancy Teague:
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 (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 located 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.
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.

Summary of Non-Clinical Performance Data:
Risk evaluations and verification and validation testing were conducted for each feature that differed from the predicate devices, Proteus Digital Health Feedback Device (K150494) and Proteus Patch, Proteus Ingestible Sensor (K133263), to the Otsuka Digital Feedback Device-RW. The results demonstrate that the acceptance criteria for firmware verification, mechanical verification, electrical verification, biocompatibility evaluation, and system verification testing were met.
Summary of Clinical Performance Data:
Clinical studies were conducted to support the expanded wear location of the patch to include the entire front abdomen. However, new clinical studies were not performed to support the changes proposed in this submission.
Conclusion:
Based on the indication for use statement, technological characteristics, risk evaluations, and device verification and validation testing, the Otsuka Digital Feedback Device-RW does not raise new questions of safety or effectiveness and is substantially equivalent to the predicate devices.
