TOKYO, April 24, 2019 -- Chugai Pharmaceutical Co., Ltd. (hereafter, “Chugai”) announced today the decision to construct a new manufacturing building for active pharmaceutical ingredients (APIs) for clinical studies in Fujieda Plant (Fujieda-shi, Shizuoka) of Chugai Pharma Manufacturing Co., Ltd. (Head office; Kita-ku, Tokyo: President; Shinya Takuma), a manufacturing subsidiary of Chugai, aiming at further accelerating development of small and middle molecule drugs.

The purpose of constructing a new manufacturing building is to newly establish the manufacturing capability of middle molecule APIs for clinical studies in Chugai, as well as to enhance the supply capacity of small molecule APIs for clinical studies. This will not only accelerate the development of small and middle molecule drugs, but also reduce manufacturing costs. In addition, the number of high-potency APIs has been increasing in Chugai. Therefore, in order to ensure the safety of the environment and our researchers, advanced containment technologies will be adopted.

By our active investment in antibody drugs, Chugai has been able to continuously create innovative projects and has established the system for simultaneous development of multiple products with a speed at a top global level. This investment for the new building will strengthen the process development speed and supply capacity of small and middle molecule drugs to obtain competitive advantage. Chugai aims to quickly deliver innovative new drugs to patients worldwide.

“Chugai has selected middle molecule drugs as the core next-generation drug discovery technology. However, given the industry’s intense competition for the development, early establishment of the technology platform for industrialization and stable supply of investigational drugs are indispensable,” said Hiroshi Murata, Vice President and General Manager of Pharmaceutical Technology Division. “A new synthetic research building is currently under construction at Ukima Research Laboratories, aiming to enhance capability of the manufacturing process development for small and middle molecule APIs. The new manufacturing building will lead to accelerate the development of small and middle molecule drugs with prompt supply of APIs by manufacturing process developed in the synthetic research building.”
