Software Treatment for Actively Reducing Severity of ADHD in Adults (STARS ADHD Adult)

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.

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.
