Otsuka and Click Therapeutics Initiate First-of-its-Kind Fully Remote Clinical Trial Using Digital Therapeutics as Adjunctive Therapy in Adults With Major Depressive Disorder

  • Primary objective of the Mirai study is to evaluate the effectiveness of digital therapeutics to reduce depressive symptoms in adults diagnosed with major depressive disorder (MDD) who are on antidepressant monotherapy
  • Trial will run fully remotely utilizing the Verily Project Baseline platform, a first-of-its-kind trial design for MDD
  • Otsuka is committed to exploring digital therapeutics in patients with serious mental illnesses like MDD, which affects more than 17 million adults in the US1

PRINCETON, N.J. and NEW YORK, N.Y. – February 24, 2021 – Otsuka Pharmaceutical Development & Commercialization, Inc. (Otsuka) and Click Therapeutics, Inc. announce the initiation of the Mirai study, a landmark fully remote clinical trial to investigate the effectiveness of digital therapeutics in reducing depressive symptoms in adults diagnosed with major depressive disorder (MDD) who are on antidepressant monotherapy.

The pivotal, randomized, controlled trial will enroll up to 540 patients nationwide. Trial participation will be 10 weeks and efficacy will be evaluated as a change from baseline in the Montgomery–Åsberg Depression Rating Scale (MADRS) total score.

“This landmark clinical trial demonstrates Otsuka’s unwavering commitment to the evolution of clinically validated, FDA-cleared digital health solutions that support patients living with mental illnesses, like major depressive disorder,” said Kabir Nath, president and CEO, Otsuka North America Pharmaceutical Business Division, Otsuka America, Inc. “The COVID-19 pandemic has clearly demonstrated the need for digital treatments and fully remote e-clinical trials that go beyond the pill to empower patients, enhance connectivity between patients and their healthcare team, and ensure more diverse populations can participate in new clinical trials.”

According to the World Health Organization, depression is a leading cause of disability worldwide, and is a major contributor to the overall global burden of disease.2 Click and Otsuka are committed to bridging the gaps between the global deficiency of mental health treatment access and the millions of patients in need of safe, effective, convenient and accessible care.

“While awareness of mental illness has grown steadily over the last decade, clinically validated therapeutic options available to patients and providers have remained essentially the same,” said David Benshoof Klein, CEO of Click Therapeutics. “Now more than ever, there is a need for a scalable digital solution that can dramatically expand access to mental health treatment without sacrificing the rigors of clinical validation or a patient-centered focus on engagement and user experience.”

Otsuka and Click will collaborate with Verily, a subsidiary of Alphabet, to execute the trial as a fully remote trial. The collaboration with Verily provides tools and technology to engage patients and clinicians, in order to increase the pace of studies and collect higher quality, more comprehensive data in a more naturalistic setting. The collaboration also enables the trial to proceed efficiently and safely in the face of the unique market challenges presented by COVID-19.
