Amgen to Terminate Participation in Co-development and Commercialization of Brodalumab

Amgen has announced the company has commenced termination of its participation in the co-development and commercialization of brodalumab with AstraZeneca. Brodalumab, an investigational IL-17 inhibitor, is in development for patients with moderate-to-severe plaque psoriasis, psoriatic arthritis, and axial spondyloarthritis. The decision was based on events of suicidal ideation and behavior in the brodalumab program, which Amgen believes likely would necessitate restrictive labeling.

"During our preparation process for regulatory submissions, we came to believe that labeling requirements likely would limit the appropriate patient population for brodalumab," said Sean E. Harper, executive vice president of R&D at Amgen. 

After Amgen transitions the program to AstraZeneca, future decisions on the clinical development and submission of marketing applications for brodalumab will be at the sole discretion of AstraZeneca for all territories, except for certain Asian territories, including Japan, where Kyowa Hakko Kirin has rights to brodalumab.

Amgen has decided to focus its efforts and resources on other key molecules that address unmet medical needs and deliver value to patients and shareholders. The Company continues to make progress against its strategic and financial commitments and does not expect any meaningful impact from this decision on its ability to meet them.
