Our Business
ACULYS is addressing the drug lag and the tackling social issues on behalf of patients. The following describes the social challenges that ACULYS addresses and features of ACULYS’s business.
Corporate Purpose
Resolving social issues associated with
neuroscience diseases
ACULYS’s corporate purpose is to serve as a catalyst for patient access to innovative medical means in the neurology area and deliver better medicine to patients, their families, workers in healthcare, and the society. We work toward resolving unmet medical needs by delivering to the Japanese market innovative medicines approved outside of Japan.
ACULYS also addresses issues that cannot be resolved with medicines alone by developing a holistic ecosystem with partners in AI, digital technology, and other fields.
Social challenges that ACULYS is addressing
Drug lag, faced by patients
Due to Japan's unique regulatory requirements and approval processes, it can take significantly longer for new drugs to receive approval and become available for use in Japan than in other countries. This delay can be a significant challenge for patients and their families, who may not have access to the latest and most effective treatments for their condition. This gap has been increasing from 2016.
According to a study on new drugs containing new active ingredients approvals in Japan and EU/US, as of 2020, 72% of pharmaceuticals approved in EU and the US in the last five years remain unapproved in Japan, totaling 176 treatments*. This delay can be a significant challenge for patients and their families, who may not have access to the latest and most effective treatments.

Drug loss, from the underdevelopment of new drugs in Japan
Around the world, startup companies play an increasingly important role in the development of new drugs, responsible for discovering and developing approximately 80% of new pharmaceuticals worldwide1). In fact, in 2020, venture companies and small to medium-sized companies generated 43 of the 53 pharmaceuticals approved by the FDA.2)
Despite these advancements, many venture companies and small to medium sized companies with limited funding do not take their innovations through the Japanese regulatory process, resulting in “Drug loss” In other words, even if the drugs have been approved in other markets such as the U.S. or the EU, they are not available to patients in Japan.

Neurology: An Area of Significant Unmet Medical Needs in Japan
In Neurology, the number of pharmaceuticals approved in EU/US but not in Japan has doubled from 11 items in 2016 to 22 items in 2020.1),and the gap continues to grow. Patient satisfaction and drug efficacy scores remain low2), highlighting further unmet medical needs.
Challenges in the disease area include not only a limitation in treatment options but also a broad range of issues that need to be resolved from a socioeconomic perspective, such as the adverse effects on patients’ social lives due to delayed diagnoses and the burden on family members or caregivers.

innovative treatments and medical means
At ACULYS, we're breaking down barriers to bring innovative neurological treatments to Japan, faster. By focusing on medicines already approved in other countries, we're cutting through Japan’s drug lag and delivering life-changing therapies to patients and families who need them.
“Beyond-the-pill”
comprehensive support system for patients
We are redefining what it means to support patients and families affected by neuroscience diseases. Our patient-and family-centered support system goes beyond our work to bring innovative neurological treatments to Japan—providing the support and solutions that patients and their families need to lead normal and healthy lives. Through collaboration with our partners and the use of AI and other digital technologies we are working to change the landscape of neurology and improve the lives of patients and families in Japan.
Outstanding knowledge and dedication
Our experienced team members, who have contributed to the growth of major global pharmaceutical companies, are combining their knowledge and expertise to achieve our mission of addressing the stigmas and social issues related to neuroscience diseases.
Pipelines
We are currently building a pipeline of three indications in the field of neuroscience diseases.
In order to meet the unmet needs of Japanese patients as quickly as possible, we have begun development of drugs that have already been approved for use overseas but not yet approved in Japan.
