Amgen and Takeda Pharmaceutical Company Limited have announced an agreement under which Takeda will develop and commercialize for the Japanese market up to 13 molecules from Amgen’s pipeline, one of which is included as an option.

This collaboration validates the significant value of Amgen’s clinical stage pipeline and further ensures Japanese patients will have access to Amgen’s innovative potential medicines for serious illnesses. The collaboration includes early to mid-stage clinical-stage candidates across a range of therapeutic areas, including oncology, inflammation, and pain.

The financial terms include an upfront cash payment to Amgen of $200 million. Takeda will also pay to Amgen up to $340 million in expected worldwide development costs for these molecules over the next several years, $362 million in success-based milestone payments, and double digit royalties on sales in Japan.

Additionally, Takeda plans to acquire all the shares of Amgen’s Japanese subsidiary, Amgen KK. We anticipate the share transaction to close in the first quarter.

In addition, Takeda will become Amgen’s worldwide partner for motesanib diphosphate (AMG 706), and will pay Amgen $100 million upfront, $175 million in success-based milestones for the first two indications, and double digit royalties on sales in Japan. Takeda will also pay 60 percent of ongoing clinical development expenses outside Japan and share potential profits outside Japan 50/50.

“We are excited about the agreements with Amgen, and also to welcome Amgen KK into Takeda Group,” said Takeda President Yasuchika Hasegawa.

The partnership includes Amgen’s Vectibix™ (panitumumab), motesanib diphosphate and additional molecules in oncology, inflammation and neurology/pain. With the exception of oncology candidate motesanib diphosphate, all molecules included in the partnership are biologics. Amgen retains certain co-promotion rights in Japan on all programs.
