SAN FRANCISCO--(BUSINESS WIRE)--Today, Limbix, a prescription digital therapeutic company developing mental health treatments for adolescents, announced positive results from a virtual randomized controlled trial of SparkRx, the company’s digital therapeutic for adolescents with symptoms of depression.
For participants that completed the program as recommended (n = 83), SparkRx led to a statistically significant reduction in depression symptoms compared to an active control app (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.
Across the full study sample of 121 participants with moderate to severe depressive symptoms, adolescents randomized to SparkRx 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 SparkRx to control was not significant (p = 0.07).
No participants experienced a serious adverse event or an unanticipated adverse device effect.
The data are being presented at the 2021 American Academy of Pediatrics National Conference by Benjamin Alouf, M.D., chief medical officer of Limbix, in a poster presentation titled “A CBT-based Digital Therapeutic is Effective in Reducing Symptoms of Depression in Adolescents.”
“At a time when more than one in five young people are struggling with depression, suicide attempts are rising, and we have a critical shortage of mental health specialists, SparkRx is an evidence-based solution that primary care providers can immediately offer their patients,” said Dr. Alouf. “We are very encouraged by these promising results and believe that SparkRx has the potential to address the growing mental health crisis in the U.S. and the need for improved access to treatment for our youth. Supported by our positive results, we are launching SparkRx and making it available for a limited time at no cost to patients or providers.”
In a separate announcement today, Limbix announced the launch of SparkRx under the U.S. Food and Drug Administration’s (FDA) Enforcement Policy for Digital Health Devices Treating Psychiatric Disorders During the COVID-19 Public Health Emergency.

SparkRx has not been cleared or approved by the FDA, nor have these trial results been validated by the FDA with regard to the safety or efficacy of SparkRx by Limbix. Limbix intends to pursue full FDA regulatory review of SparkRx. The company is working with payers to establish reimbursement to ensure SparkRx is as accessible to patients as possible should it receive FDA clearance. Patient financial support programs will also be made available for those who qualify.
