What We Do

When it comes to research at Otsuka, our mission—creating new products for better health worldwide—is at the center of everything we do. That’s why we are dedicated to finding unconventional solutions for complex, underserved medical needs, whether we are developing new compounds at one of our research facilities in the United States, Europe, Japan, and beyond; or collaborating with another company to develop innovative therapies.

What Guides Us

Our commitment

We are committed to developing new treatments in neuroscience and nephrology, where the needs of patients are underserved.

Our perseverance

We persevere, no matter how long it takes, while putting the health and safety of patients first.

Our resources

We leverage our global resources to develop unique projects that defy limitation, so that others can too.

We had a common goal and would not relent until we succeeded. We were committed to helping a niche patient population with an unmet medical need.

Neuroscience

Otsuka’s commitment to providing innovative solutions for mental health disorders started more than 30 years ago. Our research in neuroscience has been focused on treatments for adults with schizophrenia and major depressive disorder (MDD), bipolar disorder, and other neurological and neuropsychiatric conditions, including Alzheimer disease, epilepsy, attention deficit hyperactive disorder, posttraumatic stress disorder, borderline personality disorder, and autism. Each central nervous system (CNS) disorder has its own set of treatment challenges and gaps in patient care, and we seek to address these challenges with each clinical and research milestone.

It took 20 years of perseverance by our scientists to defy limitation and develop treatments for those living with CNS disorders, giving them additional medication options. At Otsuka, we respect the value within every mind. That's why our clinical development in this therapeutic area will continue to focus on addressing the gaps in mental health treatments, so those affected by CNS disorders can have more options to meet their needs.

Nephrology

Otsuka’s perseverance in developing treatments for people living with kidney disease has led to breakthroughs that have helped change the landscape of treatment options and set the stage for other new developments in nephrology. The approval of a treatment for autosomal dominant polycystic kidney disease (ADPKD) was the result of decades of research and commitment, and provided a first-in-class treatment option for ADPKD.  

We are continuing to build upon our legacy with an ongoing investment in nephrology. With changes in the measurement of outcomes that may impact disease progression, medical breakthroughs are on the horizon. We are working both internally and in collaboration with other companies that share

Our dedication goes beyond clinical advancements. In addition to drug development, we have spent years advocating on behalf of patients through programs and institutions focused on kidney disease. This continued commitment to patients, researchers, and healthcare professionals has helped us develop a proven expertise in nephrology. We will continue to serve our patients and clinicians each and every day, so they can achieve more than they thought was possible.

Digital Innovation

When it comes to digital innovation in mental health, Otsuka is at the forefront of the healthcare industry. Despite significant advances in mental health treatment over the last two decades, many people still struggle with taking their medication as prescribed. We believe digital medicine will revolutionize how patients and their caregivers manage treatment in the CNS space.

Digital medicine provides both patients and their providers with insights that help inform treatment plans and encourage communication. We started this journey in 2012, and will continue to deepen our focus on digital medicine and digital therapeutics to treat various mental health conditions. In doing so, we can help empower patients, their care teams, and their families to make more-informed decisions about their health.
