Software Treatment for Actively Reducing Severity of ADHD - Follow Up

Not Applicable

Completed

Brief Summary: This is an exploratory study to assess potential maintenance of clinical benefit (cognition and symptoms) following 4 weeks of at-home digital therapy in ADHD children.

Detailed Description: The study will be a blinded (investigators and outcome assessors), randomized (from parent study Akili-001R), parallel group, follow-up study of the sustained effects of 4-weeks of treatment with either AKL-T01 (EVO Multi) game-based digital therapy or AKL-T09 (EVO Words) game-based digital therapy.

The trial will consist of 4 visits: Screening (to be conducted at the same time as the end-of-study visit for the parent study Akili-001R), FU-Day 28 visit (conducted in clinic), and FU-Day 56 and FU-Day 84 visits (conducted remotely via electronically captured parent reported outcomes).

Recruitment & Eligibility

Inclusion Criteria

Completed Akili Study Akili-001R including all clinical assessments at DAY28 per the study protocol
Ability to comply with all the testing and requirements per this protocol

Exclusion Criteria

Participant is currently considered a suicide risk in the opinion of the Investigator, has previously made a suicide attempt, or has a prior history of, or is currently demonstrating active suicidal ideation or self-injurious behavior as measured by C-SSRS at screening
Participant has demonstrated clinically significant deterioration in functioning as assessed by PI and other study staff that would contraindicate continued participation in the follow-up study

Arm && Interventions

Group	Intervention	Description
EVO Multitasking	EVO	EVO Multitasking is a digital intervention that requires subjects to navigate a character through a game-like space, while collecting objects, in a fixed period of time. The intervention was administered to the subjects during the parent study (Akili-001R)
EVO Words	EVO	EVO Words is a digital intervention that requires subjects to spell as many words as possible, by connecting letters in a game-like grid, in a fixed period of time. The intervention was administered to the subjects during the parent study (Akili-001R)

Primary Outcome Measures

Name	Time	Method
Sustained Effects in Attention From End-of-treatment (Follow-Up Day 0) to Follow-Up Day 28 Within Groups That Were Previously Randomized to Receive 4 Weeks of Digital Therapy	Day 0 to Day 28	TOVA API is a comparison of the subject's scores based on selected measures that persons with an independent diagnosis of ADHD frequently demonstrated. The API is calculated from variability, response time, and d' (D Prime) using the following formula: API = Response Time Z score (Half 1) + d' Z score (Half 2) + Variability Z score (Total) + 1.80 where Response Time is the average time it takes to respond correctly to a target, d' score is a response discriminability score reflecting the ratio of hits to "false alarms", and Variability is a measure of consistency of speed of responding based on the standard deviation of the mean correct response times. API tells how similar the score is to the ADHD profile. A score of less than 0 indicates that the subject had similar performance to a normative ADHD population. A lower score indicates a more severe ADHD profile. The calculation for difference in TOVA API was API at Day 28 minus API at Day 0 of this study.

Secondary Outcome Measures

Name	Time	Method
Sustained Effects in Attention From End-of-treatment (Follow-Up Day 0) to Follow-Up Day 28 Across Groups That Were Previously Randomized to Receive 4 Weeks of Digital Therapy	Day 0 to Day 28	TOVA API is a comparison of the subject's scores based on selected measures that persons with an independent diagnosis of ADHD frequently demonstrated. The API is calculated from variability, response time, and d' (D Prime) using the following formula: API = Response Time Z score (Half 1) + d' Z score (Half 2) + Variability Z score (Total) + 1.80 where Response Time is the average time it takes to respond correctly to a target, d' score is a response discriminability score reflecting the ratio of hits to "false alarms", and Variability is a measure of consistency of speed of responding based on the standard deviation of the mean correct response times. API tells how similar the score is to the ADHD profile. A score of less than 0 indicates that the subject had similar performance to a normative ADHD population. A lower score indicates a more severe ADHD profile. The calculation for difference in TOVA API was API at Day 28 minus API at Day 0 of this study.
