Overview
Brief Summary
The purpose of this study is to evaluate the effects of the videogame-like digital therapy on attentional functioning and symptoms in Adults diagnosed with ADHD.
Detailed Description
This study is a multi-center, unblinded/non-controlled adaptive design study to evaluate objective attention functioning and ADHD symptoms and impairments in adults with a diagnosis of ADHD (combined or inattentive subtype), stably on or off ADHD medication, after 6 weeks of AKL-T01 treatment. A maximum of 325 total participants from 12-30 sites will be enrolled. During the Screening/baseline, participants will undergo screening to evaluate eligibility for the study. Eligible participants will continue onto baseline procedures in the same visit. Treatment phase (Day 2-42) will involve using the digital therapy at home for each participant. Compliance with treatment/use requirements will be monitored remotely during this phase. An In-Clinic assessment will be completed on Day 42 to assess key outcomes.

Outcomes
Primary Outcomes
To evaluate the efficacy of AKL-T01 as determined by the change in a digitally assessed measure, Test of Variables of Attention (TOVA®) Attention Comparison Score (ACS), of sustained and selective attention, after 6 weeks of treatment with AKL-T01
Time Frame: Study Day 1 to Study Day 42
Test of Variables of Attention (TOVA)-Attention Comparison Score (ACS) of sustained and selective attention. Measures at Day 1 and Exit/Post-Treatment Visit Day 42 TOVA ACS is a comparison of a subject's scores based on selected measures that persons with an independent diagnosis of ADHD frequently demonstrated. ACS is calculated using the following formula: TOVA ACS = 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. 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.
Secondary Outcomes
- To evaluate the change in ADHD symptoms, as determined by change in the ADHD Rating Scale-IV with adult prompts inattention sub-scale and total scale scores, after 6 weeks of treatment with AKL-T01(Study Day 1 to Study Day 42)
