Software Treatment for Actively Reducing Severity of ADHD as Adjunctive Treatment to Stimulant (STARS-ADHD Adjunctive)

The purpose of this study is to determine the effects of combining AKL-T01 (with AKL-X01 symptom tracking) as adjunctive treatment to stimulant medication, and to understand the effects of AKL-T01 treatment (with AKL-X01 symptom tracking) in participants not recently on medication.

Detailed Description

The study aims to enroll (203) participants, with a confirmed diagnoses of ADHD, at approximately 15 sites and will be divided between 2 cohorts; 130 participants will be enrolled in Cohort 1, and 73 participants will be enrolled in Cohort 2.

Cohort 1 will have been stable (adherence to a prescribed medication schedule) on a stimulant medication, but are inadequately managed by the stimulant (in the opinion of the investigator). The stimulant is managed by their own physician for at least 30 days before baseline. This is the Stimulant cohort.

Cohort 2 will have been stable without any stimulant medication for at least 30 days before the baseline. This is the Non-Stimulant cohort.

For both cohorts, at least 7 and up to 30 days before baseline, participants' caretakers will begin using AKL-X01 (Fengo) to track their participants' symptoms and behaviors.

During Treatment Phase 1 (Days 1 through 28) participants in Cohort 1 (Stimulant) will continue to receive their current stimulant plus the addition of AKL-T01. Participants in Cohort 2 (Non-Stimulant) will just receive AKL-T01. For both cohorts, during this time the caretakers will monitor their child's symptoms daily with AKL-X01.

During the 1-Month Break (Days 29 through 56) between AKL-T01 treatment phases, participants in Cohort 1 will continue to receive their current stimulant. In both cohorts, AKL-T01 will be suspended during this time. For both cohorts, during this time caretakers will continue to monitor their child's symptoms daily with AKL-X01.

During Treatment Phase 2 (Days 57 through 84), participants in Cohort 1 (stimulant) will continue to receive their current stimulant plus the addition of AKL-T01. Participants in Cohort 2 will just receive AKL-T01. For both cohorts, during this time the caretakers will monitor their child's symptoms daily with AKL-X01.

AKL-T01, or EVO Multi, is a digital intervention that requires the subject to navigate a character through a game-like space, while collecting objects, in a fixed period of time.

    • Moderate response on stimulant, but still room for improvement
    • Dose unchanged within past 30 days, but other doses have been tried previously without improvement
    • Currently taking stimulant, but parent and/or caregiver wishes not to increase dosage for any reason
    • Taking consistent stimulant dose on weekdays, but not on weekends
  11. For Cohort 2 (non-stimulant), participant must be stable off stimulant medication for ≥ 30 days prior to enrollment.

Exclusion Criteria:

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Impairment Rating Scale, Overall Impairment (Change From Baseline to Posttreatment) in Cohort 1: Stimulant
Time Frame: Day 0 to Day 28
The Impairment Rating Scale (IRS) is a parent-rated scale that assesses individualized areas of impairment for a child participant and asks parents to make a rating of how significantly these problems impact functioning across a range of domains (social, family, school, self-esteem). Parents describe the primary areas of difficulty for each child and then provide a rating (via a Visual Analog Scale) of how much the difficulties affect the different areas of functioning ranging from (1) "no problem; definitely does not need treatment or special services" to (7) "extreme problem; definitely needs treatment or special services." The total IRS is 8 items, the 8th rating overall impairment. A negative change indicated a decrease in overall impairment.
Day 0 to Day 28
Impairment Rating Scale, Overall Impairment (Change From Baseline to Posttreatment) in Cohort 2: Non-Stimulant
Time Frame: Day 0 to Day 28
The Impairment Rating Scale (IRS) is a parent-rated scale that assesses individualized areas of impairment for a child participant and asks parents to make a rating of how significantly these problems impact functioning across a range of domains (social, family, school, self-esteem).

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
ADHD-RS Total (Change From Baseline to Posttreatment) - Cohort 1: Stimulant
Time Frame: Day 0 to Day 28
The ADHD-RS-IV is an 18-item, clinician-administered questionnaire for which a parent respondent rates the frequency of occurrence of ADHD symptoms and behaviors as defined by criteria outlined for ADHD in the DSM-IV. Each item is scored on a 4-point scale ranging from 0 (rarely or never) to 3 (very often) with total scores ranging from 0-54. A higher score indicates more severe ADHD symptoms and behaviors. A negative change in total score indicates improvement from Day 0 to Day 28.
Day 0 to Day 28
ADHD-RS Total (Change From Baseline to Posttreatment) - Cohort 2: Non-Stimulant
Time Frame: Day 0 to Day 28
The ADHD-RS-IV is an 18-item, clinician-administered questionnaire for which a parent respondent rates the frequency of occurrence of ADHD symptoms and behaviors as defined by criteria outlined for ADHD in the DSM-IV. Each item is scored on a 4-point scale ranging from 0 (rarely or never) to 3 (very often) with total scores ranging from 0-54. A higher score indicates more severe ADHD symptoms and behaviors. A negative change in total score indicates improvement from Day 0 to Day 28.
Day 0 to Day 28
CGI-I (at Posttreatment) - Cohort 1: Stimulant
Time Frame: Day 28

The Clinical Global Impression Scale - Improvement (CGI-I) is a clinician's comparison of the participant's overall clinical condition at follow up to the overall clinical condition at baseline. The CGI-S is a 7-point scale where 1 = Very much improved, 2=Much improved, 3=Minimally improved, 4=No change, 5=Minimally worse, 6=Much worse, and 7=Very much worse.

A score of 1, 2, or 3 would indicate overall improvement of ADHD severity.

Day 28
CGI-I (at Posttreatment) - Cohort 2: Non-Stimulant
Time Frame: Day 28

The Clinical Global Impression Scale - Improvement (CGI-I) is a clinician's comparison of the participant's overall clinical condition at follow up to the overall clinical condition at baseline. The CGI-S is a 7-point scale where 1 = Very much improved, 2=Much improved, 3=Minimally improved, 4=No change, 5=Minimally worse, 6=Much worse, and 7=Very much worse.

A score of 1, 2, or 3 would indicate overall improvement of ADHD severity.

Day 28
Change TOVA Attention Composite Score (ACS) - Cohort 1: Stimulant
Time Frame: Day 0 to Day 28
TOVA ACS is a comparison of the subject's scores based on selected measures that persons with an independent diagnosis of ADHD frequently demonstrated. ACS is calculated from variability, response time (RT), and d' Prime using the following formula: ACS = RT Z score (Half 1) + D' Z score (Half 2) + variability Z score (Total) + 1.80 where RT 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. ACS tells how similar the score is to the ADHD profile. A score of less than -1.8 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 ACS is ACS at Baseline (Day 0) minus ACS at Day 28.
