Akili’s Clinically Proven Digital Medicine Now Authorized for Children 8-17, Opening Option to More Patients as Ongoing Stimulant Shortage Persists

Akili, Inc. (Nasdaq: AKLI), a leading digital medicine company, today announced that it has received authorization from the U.S. Food and Drug Administration (FDA) to expand the label for EndeavorRx^® from 8 to 12 year-old patients with primarily inattentive or combined-type ADHD who have a demonstrated attention issue to include older children aged 13 - 17. This increased age range is expected to more than double the number of pediatric patients with ADHD who are now eligible for EndeavorRx – the only FDA-authorized, game-based digital therapeutic – with a prescription from a healthcare provider. (Akili also offers a non-prescription product for adults with ADHD, using the same technology, EndeavorOTC™.)

The clinical study on which the FDA’s label expansion authorization for EndeavorRx is based involved 162 adolescents with a verified diagnosis of inattentive or combined-type ADHD who all received EndeavorRx for 4 weeks and subsequently demonstrated significant improvements in TOVA^Ⓡ-measured* attentional control.

“This latest FDA authorization marks another significant milestone for Akili and the Endeavor products, and more importantly it provides access to adolescents, who have been disproportionately impacted by the ongoing mental health crisis,” said Dr. Scott Kollins PhD, Chief Medical Officer at Akili. “Our pivotal study for adolescents demonstrates that EndeavorRx is a safe and effective treatment option for millions of kids and teens struggling with ADHD – particularly important given the ongoing stimulant medication shortage.”

In the same study, adolescents using EndeavorRx also saw significant improvement in clinician-rated ADHD symptoms, as measured by the Attention Deficit Hyperactive Disorder Rating Scale-5 (ADHD-RS) inattention subscale and total scale scores. ADHD-RS is a clinician-administered questionnaire based on information collected from the child's caregiver. 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 27.1% of all participants in the study demonstrated at least a 30% reduction in total scores on the ADHD-RS, a finding similar to the initial STARS-ADHD trial in 8-12 year old children with ADHD (24%). Statistically significant improvements were also observed for parent and child ratings of attention improvement, as well as parent ratings of function across a number of domains, including peer relationships, academic functioning, behavioral functioning, homework functioning, and self-esteem. Overall, 4 (2.5%) participants experienced a treatment-emergent adverse device event (3 decreased frustration tolerance, 1 headache; all mild or moderate). There were no serious adverse device events.

EndeavorRx is indicated to improve attention function as measured by computer-based testing in children ages 8 to 17 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.
