Offer SparkRx to patients today

SparkRx is a digital therapeutic that provides an evidence-based adjunct treatment intervention for adolescents aged 13-22 with symptoms of depression. We are offering SparkRx for a limited time, at no cost to patients or providers, under the FDA’s Enforcement Policy during the COVID-19 public health emergency.

For patients experiencing symptoms of depression

Designed with clinical experts in adolescent depression

SparkRx brings evidence-based treatment to each patient’s smartphone, delivering a multi-week program based on cognitive behavioral therapy (CBT) and behavioral activation protocols.²

Behavioral activation

Patients learn about the relationship between mood and behavior and identify activities that can help them feel better. The program then helps them schedule and debrief on the activities.

Interactive tasks and rewards

Patients can gain a sense of progress and achievement as they complete interactive exercises and win rewards in the app. Limbot, the program’s robot guide, helps encourage patients throughout their treatment journey.

Built-in safety features

If language indicating potential self-harm is detected in the app, patients are shown crisis resources and emergency guidance. Crisis resources are also easily accessible from the SparkRx homepage.

Demonstrating clinically meaningful reductions in depressive symptoms

SparkRx has been studied in a nationwide, randomized controlled trial (NCT04524598). The results showed clinically meaningful³⁻⁴ reductions in depressive symptoms.

Explore the data

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 (p=0.07).

Explore the data

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.

Warnings (for Clinicians)

SparkRx is not for emergency use. Please instruct patients to dial 911 or go to the nearest emergency room in the event of a medical emergency.

Patients should be clearly instructed not to use SparkRx to communicate severe, critical, or urgent information to their health care provider. Patients should also be informed that text they enter into SparkRx will not be monitored or reviewed by a health care provider. 

SparkRx is not meant to be used as treatment without supervision of a health care provider. Please instruct your patients to contact you should they notice a worsening of symptoms or an increase in thoughts of suicide or self-harm.

SparkRx is not meant to be a substitution for any treatment or medication.

SparkRx is intended for patients whose primary language is English with a reading level of 5th grade or above, and who have access to an Android/iOS smartphone or tablet. SparkRx is intended only for patients who own a smartphone or tablet and are familiar with use of smartphone or tablet apps (applications).

SparkRx contains sensitive medical information. Please instruct patients to protect their information by password protecting their smartphone or tablet, and ensuring no one else may access their device.

SparkRx does not address concerns of active suicidal ideation with intent. SparkRx is not intended for the prevention of suicide attempts or self-harm behaviors. Patients with active suicidal ideation with intent or those who have had a past suicide attempt may still be given SparkRx to help treat depression but should not be given SparkRx to prevent, treat or mitigate active suicidal ideation with intent.

Patients with posttraumatic stress disorder (PTSD) who are currently experiencing marked alterations in arousal or reactivity associated with traumatic events may find that the level of exposure related to guided behavioral activation exacerbates symptoms.
