Sumitomo Dainippon Pharma Co. Ltd., of Osaka, Japan, established corporate communications and frontier business offices, effective April 1, 2019, and plans to close its Ibaraki and Ehime manufacturing plants. The company also announced plans to rename its Singapore subsidiary, Sunovion Pharmaceuticals Asia Pacific Pte. Ltd., to Sumitomo Pharmaceuticals Asia Pacific Pte. Ltd. in April. The move comes as Sumitomo has established a new Thailand-based subsidiary, Sumitomo Pharmaceuticals (Thailand) Co. Ltd., that will be housed under Sumitomo Pharmaceuticals Asia Pacific.
