Under the terms of the agreement, Amgen will make an upfront payment to Kyowa Hakko of $100 million. Kyowa Hakko could receive up to $420 million in additional payments, including development, approval and sales milestones. Kyowa Hakko will also be entitled to receive double digit royalties on sales.
Amgen will initially acquire rights in all non-oncology indications, and Kyowa Hakko will continue its development activities in oncology until the completion of Phase IIa. At that time, Amgen may elect to reimburse Kyowa Hakko for its oncology-related development costs, expand its license to include oncology and assume the development and commercialization of KW-0761 in oncology settings.
