Jolly Good and Teijin Pharma Form a Partnership to Develop VR Digital Therapeutics for Depression

TOKYO, April 22, Japan — Jolly Good Inc. (“Jolly Good”) and Teijin Pharma Ltd. (“Teijin Pharma”) have signed a business partnership agreement to develop VR digital therapeutics (“VR DTx”) for Major Depressive Disorder (MDD). Together, they will promote the development of VR DTx for depression, aiming for PMDA regulatory approval.

Background of this agreement

This all started when Jolly Good won “Home Healthcare Award” in a program held by Teijin in Dec., 2020. Focusing of Jolly Good’s development of Cognitive Behavioral Therapy VR (“CBT VR”) for psychiatric disorders, this partnership will leverage Jolly Good’s VR technology and Teijin Pharma’s expertise in knowledge and strategic skills. They have agreed that they can support healthcare workers as well as improving the quality of life of patients.

From now on, Jolly Good and Teijin Pharma will continue to develop the system and perform clinical trials to register for PMDA regulatory approval.

About Cognitive Behavioral Therapy

Cognitive Behavioral Therapy (“CBT”) is a psychotherapy supporting patients to change their thoughts and behaviors by talking to a therapist. This therapy is based on the theory that your cognition on how you perceive things affects your mental and behavior pattern. CBT has been used as one of the options for non-medical treatment.

Our developing CBT VR for depression will be used as a supplement to the actual face-to-face therapy, supporting parts such as emotional behavior or bias of perspective. Not only will it improve the effectiveness of the treatment, but it will also lessen the burden of both healthcare workers and patients.

What is a DTx division (

Jolly Good established “DTx division” in April this year, consisting of psychiatrist, regulatory specialists, and business producers familiar with VR training for people with developmental disorders. This division will focus on developing the fundamental system of digital therapeutics using VR.

DTx division will expand their pipeline to other psychiatric diseases and lifestyle diseases using the fundamental system of VR DTx.
