Clinical Trial Summary

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.

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.

• 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.

• 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
