On June 27, 2025, Kura Oncology, Inc. (the "**Company**") and Kyowa Kirin, Inc. ("**Kyowa Kirin US**") entered into a Co-Promotion and Medical Affairs Agreement (the "**Co-Promotion Agreement**") to co-promote the Company's product candidate, ziftomenib, a potent, selective oral menin inhibitor, for the treatment of patients with acute myeloid leukemia and other hematologic malignancies in the United States and perform medical affairs activities with respect thereto. The Co-Promotion Agreement was entered into under and pursuant to the terms and conditions of that certain Collaboration and License Agreement by and among the Company, Kyowa Kirin US and Kyowa Kirin Co., Ltd.

*United States Co-Promotion*. Under the terms of the Co-Promotion Agreement, Kyowa Kirin US will have the right and responsibility to co-promote ziftomenib for up to a certain percentage of the details in the United States, and will be obligated to meet minimum detailing requirements using sales representatives that meet specific qualifications. The parties will perform such co-promotion activities, and share equally in all costs and expenses therefor, in accordance with the Collaboration Agreement.

The Co-Promotion Agreement will automatically terminate upon termination of the Collaboration Agreement. Either party may terminate the Co-Promotion Agreement for uncured material breach by the other party.
