Kosuke Kuronuma
EP-Bio Partners is a new company of the EPS Group established in June 2022 and from October 2024, it has become a subsidiary company wholly owned by EPS Holdings. Our business is an IRO* that provides development of business plans of biotech ventures and overseas biotech companies and also provide development support for each pipeline.
The business environment for drug development in Japan and overseas has changed significantly in recent years.
First of all, number of clinical trials conducted in Japan are on the downward trend. On the other hand, many biotech ventures have been establishing in Japan. In addition, there is an increase in the number of new modality drugs and the development of new drugs for rare diseases. In order to accelerate the development of these Japan-originated pipelines, several measures including financial support implemented by Japanese government for bio-ventures and academia have been increasing.
In addition, many overseas biotech companies plan to enter into Japanese Pharma Market and conduct clinical trials in Japan to obtain IND approval. In fact, the number of pipelines and clinical trials by overseas companies in Asia, China, EU and US is growing.
On the other hand, only the financial support to these companies is not sufficient to accelerate these companies’ business in Japan and development of their pipelines.
Traditionally, big pharmaceutical companies have all functions for the development inside their companies. But, to accelerate the development of Japanese bio venture companies and overseas biotech companies, a horizontal functions (VC, academia, CDMO, CMO, CRO, SMO, etc.) is necessary because these companies are not able to have all functions inside. Furthermore, in order to promote such a new system, we believe it is necessary to have a function and a role to connect, coordinate, and promote the entire process and functions to these companies.
For the overseas biotech companies, in order to start development of their pipelines there are several barriers, not only language barriers, but also some unique barriers of Japanese regulatory sciences, clinical trial systems at medical institutions and academia.
In order to solve these issues, our company’s role is to provide a comprehensive consultation service and to facilitate to help biotech ventures and overseas biotech companies smoothly for smooth development in Japan.
To achieve them, we go beyond the framework of a conventional CRO to provide one-stop solutions as an IRO, starting with consulting and leading to clinical trials and regulatory approval.
We would like to contribute to the sustainable development of the Japanese pharmaceutical industry and to the construction of a new ecosystem that includes biotech ventures, academia, and overseas biotech companies.
* IRO: Innovative Research Organization. It is not limited to conventional CRO services, but also provides support for the client’s business itself, from development planning consulting for each pipeline to clinical development.
In other words, IRO is one-stop solution service from business planning to clinical development consultation and clinical development operation.
