EndeavorOTC is a digital therapeutic indicated to improve attention as measured by computer-based testing in patients 18 and older with primarily inattentive or combined type ADHD, who have a demonstrated attention issue. Patients who engage with EndeavorOTC demonstrate improvements in a digitally assessed measure, Test of Variables of Attention (TOVA®) of sustained and selective attention and may not display benefits in typical behavioral symptoms such as hyperactivity. EndeavorOTC is not intended to be a replacement for any form of treatment and should be used as part of a therapeutic program that may include clinician-directed therapy, medicational programs, which further address symptoms of the disorder.

EndeavorOTC is software-as-a-medical device (SaMD) that resides on the user's mobile device and can be executed at home. It is an over-the-counter (OTC) digital therapeutic indicated to improve attention function as measured by computer-based testing in patients 18 and older with primarily inattentive or combined type ADHD, who have a demonstrated attention issue. Patients who engage with EndeavorOTC demonstrate improvements in a digitally assessed measure, Test of Variables of Attention (TOVA®) of sustained and selective attention and may not display benefits in typical behavioral symptoms such as hyperactivity. EndeavorOTC is not intended to be a replacement for any form of treatment and should be used as part of a therapeutic program that may include clinician-directed therapy, medication, and/or educational programs, which further address symptoms of the disorder. The device is built on Akili's proprietary, patented, technology platform. EndeavorOTC uses adaptive algorithms (also known as Selective Stimulus Management Engine, SSME™) to deliver stimuli that are designed to engage the patient in a manner that improves their attention function. In a closed-loop system, the adaptive SSME™ algorithms automatically adjust the difficulty level for a personalized treatment experience that is tailored to the needs of each individual patient. EndeavorOTC is delivered through a video game experience which leverages art, music, storytelling, and reward cycles to keep patients engaged. The adaptive algorithm constantly pushes patients precisely at predefined performance bounds relative to each individual, such that they are continuously encouraged to exceed their historic performance. The science behind EndeavorOTC was developed at the University of California, San Francisco by Adam Gazzaley, M.D., Ph.D., Founding Director of the University of California San Francisco's Neuroscape and Akili's Chief Science Advisor. The basic program inputs are steering, which is accomplished by using the mobile device's internal accelerometer to measure the degree to which it is tilted, and tapping, which is accomplished using the touch screen to measure correct and incorrect targeting. The basic outputs are the visual display of the game progression along with audio, which is accomplished by using the internal high resolution display and internal speaker. The program includes features to ensure it is used per the recommended regimen (approximately 25 minutes per day, 5 days per week, for 6 weeks).

Here's a summary of the acceptance criteria and the study proving the EndeavorOTC device meets those criteria, based on the provided FDA 510(k) summary:

Device Acceptance Criteria and Performance Study: EndeavorOTC

Device Name: EndeavorOTC
Regulatory Class: Class II
Product Code: QFT
Indication for Use: Digital therapeutic indicated to improve attention as measured by computer-based testing in patients 18 and older with primarily inattentive or combined type ADHD, who have a demonstrated attention issue.

1. Table of Acceptance Criteria and Reported Device Performance

The primary acceptance criteria for EndeavorOTC are based on demonstrating an improvement in attention, as measured by the Test of Variables of Attention (TOVA®) Attention Comparison Score (ACS), and showing a favorable safety profile in the indicated adult population. The 510(k) summary refers to "clinical performance study support[ing] the performance and safety of EndeavorOTC in the adult age range" and "a statistically significant positive mean change from baseline to study day 42 in the TOVA".

Based on the provided document, the key efficacy performance criterion appears to be a statistically significant positive change in the TOVA-ACS.
