PureTech Founded Entity Akili Announces Adults with ADHD See Significant Improvements in Attention, ADHD Symptoms, and Quality of Life in Clinical Trial of Akili’s EndeavorRx® Video Game-Based Therapeutic
Attention improved in more than 80 percent of adults with ADHD, and over one-third of participants no longer exhibited an attention deficit following treatment
Improvements in attention were nearly seven times larger than those seen in the pivotal trial that supported EndeavorRx’s FDA authorization for 8-12 year olds with ADHD
Nearly half of adults treated with EndeavorRx met a prespecified threshold for clinically meaningful improvement in their quality of life
The multi-center open-label study (NCT05183919) enrolled 221 adults, 18 years of age and older, with inattentive or combined-type ADHD. Patients used the video game-based digital treatment on a mobile device in their homes for six weeks. In the study, EndeavorRx demonstrated a statistically significant improvement in the Test of Variables of Attention (TOVA®)-Attention Comparison Score (ACS) of sustained and selective attention from baseline after six weeks of treatment (p<0.0001), the study’s predefined primary efficacy outcome. The change from baseline on the TOVA ACS was 6.46 points, which is more than twice as large as the changes seen in the recent pivotal study in adolescents (2.64 points) and nearly seven times as large as the changes seen in STARS-ADHD (0.93 points), a large randomized controlled trial of children with ADHD ages 8-12 that served as the basis for EndeavorRx’s FDA authorization in that age group. TOVA is a computerized test authorized by the FDA to aid in the diagnosis of ADHD and evaluate the effects of interventions in ADHD.
Akili plans to present full data from the STARS-ADHD-Adult study at a future scientific meeting and will submit the data to the FDA later this year.

BOSTON—May 3, 2023 -- Akili, Inc. (Nasdaq: AKLI), a leading digital medicine company, today announced topline results of the STARS-ADHD-Adult clinical trial evaluating the efficacy and safety of EndeavorRxⓇ (AKL-T01) in adults with attention-deficit/hyperactivity disorder (ADHD). STARS-ADHD-Adult was designed as a pivotal clinical trial to enable registration with the
Millions of American adults are diagnosed with ADHD, and recent reports suggest that rates have risen in recent years. This is magnified by the substantial challenges this large group of patients face in accessing effective treatment.
EndeavorRx is currently authorized by the FDA for the treatment of inattention in children ages 8-12 with ADHD (see full indication below), and in January Akili announced topline data from a successful pivotal study of EndeavorRx in adolescents with ADHD ages 13-17. For both objective measures of attention and clinical outcomes, the improvements observed in adults surpassed those in both the pediatric and adolescent patient populations.
“Not only did the benefit of EndeavorRx in adults with ADHD exceed what we’ve seen in kids and adolescents, adults using the treatment experienced meaningful improvements in their quality of life,” said Scott Kollins, Ph.D., chief medical officer of Akili. “These data come at a critical time when there is growing demand among adults with ADHD for safe, effective, and accessible non-drug treatments. It is increasingly recognized that current available options are not working, and/or are not available. We are deeply committed to getting this treatment to patients as quickly as possible. We are evaluating regulatory strategies and look forward to sharing more soon.”

TOVA is a computerized test authorized by the FDA to aid in the diagnosis of ADHD and evaluate the effects of interventions in ADHD.
Adults using EndeavorRx also showed significant improvement in their ADHD symptoms, as measured by the clinician-administered Attention Deficit Hyperactive Disorder Rating Scale-5 (ADHD-RS). Following treatment, participants in the study showed significant improvement on both the inattention subscale and total score of the ADHD-RS (p<0.0001 for both). A prespecified responder analysis also showed that

Additional study information and results:
-
83% patients demonstrated a clinical response to the treatment on the TOVA-ACS (post hoc analysis as measured by at least a 1.4 improvement on the TOVA) -
More than one-third (
36.6% ) of adults with ADHD moved into the non-clinical, or normative, range (TOVA ACS score of >0) - Quality of life improvements seen included an increased ability to complete projects and tasks on time, ability to balance multiple projects at a time, and ability to keep track of important items such as keys and wallet
-
Approximately
70% of the adults with ADHD in the study were women -
40% of patients enrolled were taking ADHD medication; a similar magnitude of effect was seen both in those taking stimulant medications and in those not taking stimulants
Akili plans to present full data from the STARS-ADHD-Adult study at a future scientific meeting and will submit the data to the FDA later this year.
EndeavorRx Indication and Overview
EndeavorRx is the first-and-only FDA-authorized treatment delivered through a video game experience. EndeavorRx is indicated to improve attention function as measured by computer-based testing in children ages 8 to 12 years old with primarily inattentive or combined-type ADHD, who have a demonstrated attention issue. Patients who engage with EndeavorRx 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. EndeavorRx should be considered for use as part of a therapeutic program that may include clinician-directed therapy, medication, and/or educational programs, which further address symptoms of the disorder. EndeavorRx is available by prescription only. It is not intended to be used as a stand-alone therapeutic and is not a substitution for a child’s medication. The most common side effect observed in children in EndeavorRx’s clinical trials was a feeling of frustration, as the game can be quite challenging at times. No serious adverse events were associated with its use. EndeavorRx is recommended to be used for approximately 25 minutes a day, 5 days a week, over initially at least 4 consecutive weeks, or as recommended by your child’s health care provider.
