Otsuka Pharmaceutical Co., Ltd. (大塚製薬株式会社 Ōtsuka Seiyaku Kabushiki-gaisha) (TYO: 4578), abbreviated OPC, is a pharmaceutical company headquartered in Tokyo, Osaka and Naruto, Japan. The company was established August 10, 1964.
OPC's parent company Otsuka Holdings Co. Ltd. joined the Tokyo Stock Exchange through an initial public offering (IPO) on December 15, 2010, at which time Otsuka Holdings was Japan's No.2 drug maker by sales after industry leader Takeda Pharmaceutical Company. The IPO debuted at $2.4 billion, making it the largest for a pharmaceutical company up to that time.
In early 2012, Otsuka announced it would focus its "future operations on CNS disorders and oncology". This decision necessitated a revision in the terms of an agreement with UCB to end collaboration on immunology products while continuing collaboration in the CNS area.
In March 2017, the company agreed to acquire Neurovance, Inc. for $250 million, gaining the firm’s Phase III-ready ADHD drug centanafadine (previously EB-1020). Otsuka's subsidiary Otsuka America will pay $100 million upfront for Neurovance, plus up-to $150 million in development and approval milestones. As a result of the transaction, Neurovance will operate as an indirect, wholly owned subsidiary.
