Our Clinical Trials

Clinical trials play a critical role in research and in making discoveries in healthcare. It’s these breakthroughs in science that help people defy the limitation of their disease. This would not be possible without the participation of patients, who are at the heart of everything we do.

Clinical Trials, Research & Development

What Are Clinical Trials

Clinical trials are research studies performed on people that are aimed at evaluating a medical, surgical, or behavioral intervention. They are the primary way to understand if a new treatment, such as a drug, diet, or medical device (such as a pacemaker) is safe and effective for people. A clinical trial may learn if a new treatment is more effective and/or has fewer side effects than the standard or current treatment(s).​

Benefits of Participating in Clinical Trials

  • You play a more active role in your own health care​​
  • Researchers may add more frequent health check-ups as part of your treatment.​​
  • Possible early access to a new treatment before it is available to the general public​​
  • You have the chance to help others get a better treatment for their health problems​

What happens in a clinical trial?​

The specifics of the clinical trial depend on the study protocol, a detailed plan explaining the purpose of the trial and what activities the trial will include. Before participating in a clinical trial, potential participants will review the informed consent form. This informed consent will include:​

  • The purpose of the trial​
  • The length of the trial​
  • The medicines, procedures, and tests in the trial
  • A schedule of activities
  • Potential side effects

Who can join a clinical trial?

Everyone is encouraged to consider participating in a clinical trial. It is important clinical trials include a diverse participant pool, including, but not limited to, diversity of age, race, ethnicity, gender, education level, and socioeconomic status.

Each clinical trial has its own criteria of who can participate in a clinical trial, known as eligibility criteria. Eligibility criteria could include whether you have been diagnosed with the illness of interest, current medications you take, or if you have other illnesses.

Otsuka's Clinical Trials

Otsuka's Clinical Trials

Otsuka’s commitment to innovation extends to empowering patients and healthcare professionals through our new Clinical Trials website. Find out more about our research, search for clinical trials, read plain language summaries, and join the HCP network.

By providing accessible resources and insights, we put patients and their communities at the center of our research efforts, fostering a future where transparency and inclusion drive scientific advancement.

The Importance of Diversity In Clinical Trials

Diversity in clinical trials is an important aspect to health equity. The data from clinical research studies are used to determine how well a product works and how safe it is. However, in the history of clinical research, people of different races and socioeconomic status were often not included. Otsuka is committed to improving diversity in our clinical trials and addressing health disparities. We aim to enroll diverse patient populations in our clinical trials including people from different races and ethnicities, gender, sexual orientation, age, disability, and socioeconomics.

Transparency In Clinical Trials

If you are a clinical researcher and would like more information on the clinical trial datasharing program, please visit the Otsuka Clinical Trial Data Transparency website.

Clinical Trial Access

For patients who may want to participate in a clinical trial, but may not be able to, there is still a possibility to access an investigational drug through the Expanded Access program. 

Expanded access, also known as compassionate use, allows for an investigational medical product that has not yet been approved by the FDA to be used outside of a clinical trial. Otsuka accepts requests for expanded access from physicians currently treating patients for whom there are no other treatment options available. 

To be eligible for access to an investigational product, the applying physician must certify that the patient for whom the application is being submitted meets the following criteria*:

Is suffering from a serious or life-threatening disease or condition

Is not able to participate in any ongoing clinical study of the drug related to the treatment of the patient’s condition

Has undergone appropriate standard treatments without success and there is no alternative treatment available, or no standard treatment exists for the disease or condition

The potential benefits for the patient must outweigh the potential risks

The provision of the drug will not interfere with the development of the product

Note that meeting these criteria does not guarantee access to any investigational product. 

Contact us at [email protected] with any questions, or to request an application form or submit a completed application form.

Otsuka will confirm receipt of an application within one week and will advise of any additionally required information after the initial review of the application. 

What We Do

Our research facilities and collaborations around the world exist to serve the complex, underserved medical needs of patients and caregivers. Our mission—creating new products for better health worldwide—is at the center of everything we do.

Our Focus

Our mission comes to life through 2 important categories.

Neuroscience

Otsuka’s commitment to providing innovative solutions for mental health disorders started more than 30 years ago. Our research in neuroscience maintains its focus on potential 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. We seek to address the unmet medical needs of all those we serve as we explore our focus on anxiety disorders, frontotemporal dementia (FTD), Lewy Body dementia, Fragile X syndrome (FXS) and amyotrophic lateral sclerosis (ALS), among other conditions. 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, creativity, and innovation 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 continues to address the gaps in mental health treatments by exploring the cutting edge of psychiatrics, so those affected by CNS disorders can have more options to meet their needs.

Nephrology

Otsuka’s enduring perseverance to advancing treatments for individuals living with kidney disease has lead to breakthroughs that significantly reshape treatment landscapes and pave the way for further innovation. The approval of a treatment for autosomal dominant polycystic kidney disease (ADPKD) was the result of decades of research and commitment and provides a first-in-class treatment option for ADPKD. We uphold our commitment to addressing the unmet medical needs within this space.

We are extending our legacy through ongoing investments in nephrology and in new areas. With changes in the measurement of outcomes that may impact disease progression, medical breakthroughs are on the horizon. With Visterra joining the Otsuka corporate family in 2018 and in collaborating with other like-minded companies that share our values, we are dedicated to enhancing our commitment in nephrology and addressing other critical areas with unmet needs.

Alongside drug development, we have devoted years to advocating for patients through programs and institutions focused on kidney disease. This steadfast commitment to patients, researchers, and healthcare professionals has fortified Otsuka’s expertise in advocacy. We remain steadfast in our mission to serve our patients and clinicians every day, so they can achieve even more than they thought was possible.
