Core therapeutic and research areas

Company disclosures emphasize several areas of ongoing research and development:

• Atopic dermatitis (AD): Kyowa Kirin, in collaboration with Amgen, is evaluating rocatinlimab, an investigational anti-OX40 human monoclonal antibody described as a potential T-cell rebalancing therapy for moderate to severe atopic dermatitis. The ROCKET Phase 3 clinical program includes multiple global studies such as HORIZON, IGNITE, SHUTTLE, VOYAGER and ASCEND, designed to assess efficacy, safety, tolerability and long-term maintenance of response in adults and adolescents.
• Hematology and hemato-oncology: The company states that it develops therapies for intractable hematological diseases and hematologic/oncologic conditions. A notable example is a global strategic collaboration with Kura Oncology to develop and commercialize ziftomenib, a selective oral menin inhibitor being investigated for acute myeloid leukemia (AML) and other hematologic malignancies.
• Bone and mineral disorders: Kyowa Kirin reports extensive work in rare bone and mineral diseases, particularly X-linked hypophosphatemia. The company supports the XLH Disease Monitoring Program, a long-term observational effort to better characterize disease burden and outcomes, and presents real-world data and clinical findings at scientific meetings.
• Cell and gene therapy research: Across multiple statements, Kyowa Kirin notes that it is working to engineer next-generation antibodies and cell and gene therapies aimed at patients with limited or no treatment options.

Key collaborations and partnerships

Kyowa Kirin’s recent announcements highlight several long-term and strategic collaborations that shape its pipeline:

• Amgen collaboration: Under an agreement initiated on June 1, 2021, Kyowa Kirin and Amgen jointly develop and commercialize rocatinlimab (also referred to as KHK4083/AMG 451). Amgen leads development, manufacturing and commercialization in markets outside Japan, while Kyowa Kirin retains all rights in Japan. If rocatinlimab is approved, the companies plan co-promotion in the United States, and Kyowa Kirin has opt-in rights to co-promote in certain European and Asian markets.
• La Jolla Institute for Immunology (LJI): Kyowa Kirin maintains a long-running academic–industry alliance with LJI focused on immunology and drug discovery. The partnership has produced candidate compounds and underpins work on immunotherapies, including the initial discovery of the antibody that led to rocatinlimab. Recent agreements extend this collaboration and emphasize joint work in cell and gene therapies.
• Kura Oncology collaboration: A global strategic collaboration gives Kyowa Kirin exclusive commercialization rights for ziftomenib outside the United States, while the companies share responsibilities for development and commercialization under a global development plan. Kyowa Kirin indicates that it will apply its hemato-oncology experience and capabilities to bring this investigational therapy to market, subject to regulatory review.

Clinical development and scientific focus

Kyowa Kirin’s communications place strong emphasis on clinical research and evidence generation. For atopic dermatitis, the ROCKET Phase 3 program is described as a comprehensive, global set of eight studies intended to establish the safety and efficacy profile of rocatinlimab across multiple dosing regimens and patient populations. Trials such as HORIZON and IGNITE are randomized, placebo-controlled, double-blind studies that assess endpoints including EASI-75, validated Investigator Global Assessment (vIGA-AD), revised Investigator Global Assessment (rIGA), itch scores, quality of life measures and long-term maintenance of response.

In bone and mineral disorders, Kyowa Kirin supports real-world research on XLH, including analyses of work productivity, quality of life and treatment outcomes. The company also shares data on burosumab (CRYSVITA), a fibroblast growth factor 23 (FGF23) blocking antibody discovered by Kyowa Kirin and indicated in the United States for the treatment of X-linked hypophosphatemia in adult and pediatric patients 6 months of age and older. Company materials describe CRYSVITA’s mechanism of action as binding to and inhibiting FGF23, thereby influencing phosphate handling and vitamin D metabolism.

Geographic footprint and corporate identity

Kyowa Kirin describes itself as a Japan-based global specialty pharmaceutical company. It notes operations and engagement across regions including Japan, Asia Pacific, North America and EMEA/International. Subsidiaries such as Kyowa Kirin, Inc. in North America and Kyowa Kirin Canada, Inc. are referenced in communications from locations such as Princeton, New Jersey. The company emphasizes a shared set of values, a focus on sustainable growth and an aspiration to create treatments that bring what it characterizes as life-changing value to patients and "make people smile" across the globe.
