On Apr. 1, 2020, Amgen announced it had consummated the purchase from Astellas of 49% of shares of Amgen Astellas BioPharma K.K., a joint venture between Amgen and Astellas established in 2013. AABP, which is now a wholly-owned Amgen affiliate in Japan renamed Amgen K.K., has enabled Amgen to build a strong presence in Japan as it advances treatments for serious illnesses.

Since 2011, Amgen has expanded its geographic presence from approximately 50 to 100 countries, enabling the company to play a growing role in serving the rapidly increasing demand for better healthcare around the world. In 2019, Amgen invested more than $4 billion in research and development to advance numerous potential new medicines across all stages of our pipeline.

Amgen K.K. is a wholly owned Japanese affiliate of Amgen Inc., one of the largest independent biotechnology companies in the world. Amgen K.K., formerly Amgen Astellas BioPharma K.K., was established in October 2013 as joint venture between Amgen and Astellas, and changed its corporate name when it became a wholly owned subsidiary of Amgen.
