Demonstrating clinically meaningful reductions in depressive symptoms

SparkRx has been studied in a nationwide, randomized controlled trial (NCT04524598). The results showed clinically meaningful ¹⁻² reductions in depressive symptoms.

Intention-to-Treat Analysis

Participants who received SparkRx (n = 63) showed a clinically meaningful reduction in depression symptoms. At the end of the study, 24% of SparkRx participants had a treatment response and 17% were in remission. The intention-to-treat analysis comparing Spark to Control was not significant.

Per-Protocol Analysis

For participants that consistently engaged with their assigned program (n = 83), SparkRx led to a statistically significant reduction in depression symptoms compared to Control (p = 0.023) and a 21% remission rate compared to a 4% remission rate for Control at the end of treatment. Treatment response rates were 29% and 16%, respectively, for SparkRx and Control.

Grounded in Clinically Validated Treatment

Cognitive-behavioral therapy (CBT) has been shown to be effective in the prevention and treatment of depression in children and adolescents, and is recommended as a first-line treatment for depression by the American Academy of Pediatrics.

Because certain neural systems in the brains of adolescents are still developing, teenagers demonstrate more reward-seeking behaviors than adults and have a greater tendency to engage in harmful and avoidant behaviors during depressive episodes. 

Reinforcing healthy behaviors and social engagement may be particularly helpful for treating depression in adolescents. A focus on psychoeducation and encouraging and reinforcing positive behavior may also be appealing to teenagers who struggle with the corrective approach that supports some traditional therapy models.
