Schizophrenia Spectrum disorders (SSD) are among the most devastating psychiatric disorders. Prominent negative symptoms such as low motivation, anhedonia, asociality, and emotional flattening are experienced by up to 60% of individuals with SSD and are often considered to be the greatest contributors to functional disability. Currently, there are no FDA-approved or cleared medications or therapeutics targeting negative symptoms of schizophrenia. In this phase I proposal, North Shore Therapeutics (NST) is collaborating with the Feinstein Institutes of Medical Research (FIMR; Northwell Health) and the University of Pennsylvania (Penn) to develop a novel augmented reality (AR) therapeutic (NST-SPARK) targeting negative symptoms in individuals with SSD. NST-SPARK is a smartphone application that delivers Recovery-oriented Cognitive Therapy (CT-R) via gamified AR experiences to provide experiential learning that dismantles maladaptive beliefs. Preliminary findings suggest that this approach is feasible, acceptable, and may reduce defeatist beliefs associated with negative symptoms. NST-SPARK v.2.0 is being developed in partnership with a lived experience advisory panel. NST-SPARK v2.0 will deliver a 12-week course of treatment and will be developed over 10 development sprints spanning 9 months. In the second phase, the investigators will introduce NST-SPARK v2.0 to individuals with SSD (n=30) and moderate to severe negative symptoms for 12 weeks in a single-arm open-label study. The primary outcome is the efficacy of NST-SPARK v.2.0 in reducing experiential negative symptoms. Secondary outcomes include efficacy in reducing defeatist beliefs; efficacy in improving functioning; user statistics quantifying adherence to the prescribed sessions; qualitative, semi-structured feedback to guide future product development. This study will set the stage for FDA-informed phase II trials.
