Depression affects more than 3.2 million adolescents in the USA, with rising incidence and suicide rates thatcarry devastating personal, societal, and economic impact. Effective care for adolescent depression is limiteddue to lack of access, shortage of providers, long waitlists, stigma, and ineffective or partially effectivepharmacological options. Many adolescents with depression are initially diagnosed and receive treatment fromprimary care providers, who, unfortunately, often have limited time, training, and options to be effectivegatekeepers for treatment. There is an urgent need for accessible, cost-effective, and clinically-validatedtreatment options for adolescents diagnosed with depression, particularly in primary care settings. Digitalhealth interventions represent an exciting and promising new direction for mental health treatment with strongpotential to increase access to care. Such technology is especially critical and timely during this period ofmandated physical distancing, which is expected to increase social isolation and exacerbate difficulties inreceiving care. Currently available commercial digital health options widely lack clinical validation, cannot makestrong medical claims, and are not specifically designed for adolescents. We aim to develop an FDA-cleared,self-guided, cognitive behavioral therapy (CBT)-based mobile program (Limbix Spark) to be prescribed byprimary care providers and psychiatrists and commercialized for at-home patient use as first line treatment.Limbix Spark implements behavioral activation, a key CBT skill that provides a sense of pleasure or masterythrough self-monitored activities to reduce depressive symptoms and improve functional outcomes. Givenyouth ease with and preference for technological solutions, an age-appropriate and engaging mobileintervention can be both beneficial and enjoyable. Building on outcomes from a feasibility trial demonstratinghigh feasibility and engagement, and preliminary evidence of clinically meaningful reductions in depressivesymptoms, in Phase I of the proposed Fast Track, we will conduct rigorous testing to optimize our Limbix Sparkprogram and show high usability, build a regulatory compliant platform, and prepare for a Phase II clinical trial.In Phase II, we will demonstrate clinical effectiveness of Limbix Spark by conducting a double-blind, placebocontrolled, randomized clinical trial with patients recruited and enrolled from primary care and psychiatricclinics. The team, led by veteran entrepreneurs, research professionals, industry leaders, and clinical experts,is singularly qualified to conduct the proposed research and commercialize Limbix Spark as an adolescentdepression prescription digital therapeutic, accelerating access to care for a severely underserved population.
Public Health Relevance Statement: Project Narrative
Depression impacts over 3 million adolescents in the United States, with incidence rates on the rise, yet there
are continued barriers to effective treatment. Digital health interventions based on cognitive behavioral therapy
represent a critical and exciting new direction for treatment and have the promise to reach an unprecedented
number of adolescents. The overarching goal of the proposed project is to develop a cost-effective,
clinically-validated, and engaging digital therapeutic that can be prescribed by pediatric primary care and
psychiatric providers in order to overcome a significant barrier in access to effective care for adolescents with
depression, a segment of the population with substantial unmet mental health needs.
