Software Treatments for Actively Reducing Severity of Cognitive Deficits in MDD (STARS-MDD)
November 19, 2018 updated by: Akili Interactive Labs, Inc.
A Randomized, Double-blind, Controlled, 6-week Trial to Assess the Impact of Novel Digital Interventions Designed to Improve Cognitive Dysfunction as Adjunct Therapy to Antidepressant Medication in Adults With Major Depressive Disorder
The purpose of this study is to evaluate the effects of videogame-like digital therapies as adjunct therapy to antidepressant medications on cognitive deficits associated with major depressive disorder.

Detailed Description
The study will be a randomized, parallel group, controlled trial of two videogame-like (iPad-based) digital therapies.
The study will consist of 3 primary phases: Pre-screening, Baseline, and Treatment.
During the Pre-screening Phase (Day -28 to Day 0), participants will undergo pre-screening to evaluate eligibility for the study.
Pre-screening may take place up to 28 days before the Baseline Visit (Day 0).
Pre-screening may take place either over the phone, or in the clinic.
On Day 0, the Baseline visit will occur wherein additional eligibility criteria will be established.
The Treatment Phase (Day 1 to Day 42) will involve using the digital therapy at home for each participant followed by an In-Clinic assessment on Day 42 to assess key outcomes.
During the Treatment Phase participants will be instructed to play their videogame-like intervention for approximately 25 minutes per day for 5 days per week.
Compliance with treatment/use requirements will be monitored remotely during this phase.

- Pre-Screening (Day≤-28) Remote or In-Clinic
- Screening/Day 0 (in-clinic) including:
- HAM-D-17 score
- BAC Symbol Coding T-test score
- On stable antidepressant medication for ≥8 weeks prior to screening/baseline, with stable dose for ≥4 weeks prior to baseline/baseline, with or without stable adjunct psychotherapy (excluding DBT or CBT) for ≥12 weeks.
- Access to and self-report of ability to connect wireless devices to a functional wireless network
- Ability to follow written and verbal instructions (English) as assessed by the PI and/or study coordinator
- Normal color vision as tested by Ishihara Color Blindness Test

Exclusion Criteria:
- Current controlled (requiring a restricted medication) or uncontrolled, comorbid psychiatric diagnosis with significant symptoms including but not limited to post-traumatic stress disorder, psychosis, bipolar illness, pervasive developmental disorder, severe obsessive compulsive disorder, severe depressive or anxiety disorder, conduct disorder, ADHD or other symptomatic manifestations that in the opinion of the Investigator may confound study data/assessments.
- Initiation or completion of psychotherapy within the last 12 weeks prior to screening/baseline. The participant should inform the Investigator if they intend to change their psychotherapy during the 6 weeks of the study. Participants who have been in psychotherapy consistently for more than 12 weeks may participate if their routine is stable throughout the study.

- Self-report of recent episodes (within the past week) of nausea, vomiting and/or dizziness.
- Participation in a clinical trial within 3 months prior to screening.
- Color blindness as detected by Ishihara Color Blindness Test
- Regular use of psychoactive drugs other than antidepressants, including stimulants that in the opinion of the Investigator may confound study data/assessments.
- Use of benzodiazepines >3 times per week and/or within 24 hours of baseline and exit visit assessments prohibited.
- Use of marijuana or alcohol on the day of clinical visits before baseline or exit assessments, no tobacco within 30 minutes of TOVA
- Any other medical condition that in the opinion of the Investigator may confound study data/assessments.
- Previous exposure to Akili products.
