Key Products and Therapeutic Areas

Top-Selling Drugs
When analyzing the top-selling drugs of Kyowa Hakko Kirin, the product category that stands out is its portfolio in hematology supportive care—particularly the granulocyte colony-stimulating factor (G-CSF) biologics. Two key products in this area are:

1. Neulasta® / Peglasta® (Pegfilgrastim):
In recent years, Kyowa Hakko Kirin’s pegfilgrastim formulations—marketed under the names Neulasta® in certain regions and Peglasta® in others—have emerged as top-selling drugs. Pegfilgrastim is a long-acting G-CSF used to reduce the incidence of infection in patients undergoing chemotherapy by stimulating the production of neutrophils. This drug not only serves a critical need in cancer supportive care but has also earned its place in the top 15 best-selling drugs globally in its respective categories. Kyowa Hakko Kirin’s sustained success with pegfilgrastim is partly due to its extensive clinical validation, robust market penetration, and the strategic focus on high-growth geographies where cancer incidence is rising.

2. Filgrastim (Marketed as “Gran” in select regions):
Alongside pegfilgrastim, Kyowa Hakko Kirin also retains rights to filgrastim under regional brand names such as Gran in China, Japan, South Korea, Malaysia, and Taiwan. Filgrastim is the shorter-acting analog of G-CSF and is used to treat neutropenia arising from chemotherapy. Although its clinical utility overlaps with that of pegfilgrastim, filgrastim caters to specific market segments and provides a complementary product line that enhances the company’s overall competitive edge in the supportive care arena.

These products are central to Kyowa Hakko Kirin’s revenue generation in the oncology supportive care segment. Their top-selling status is bolstered by a strong global market presence, high clinical efficacy, and the ability to meet a persisting unmet need for effective mitigation of chemotherapy-induced neutropenia. The widespread clinical adoption of these therapies across multiple geographies is a testament to their robust performance and aligns with the company’s ongoing focus on biologics-driven innovation.

Beyond these leading G-CSF products, Kyowa Hakko Kirin has a diverse portfolio that includes other therapeutic areas; however, when it comes to top-selling drugs by revenue and market impact, the pegfilgrastim and filgrastim lines are the most prominent. The company’s emphasis on these drugs reflects an overarching strategy aimed at combining innovative technology with clinical necessity in the high-stakes field of oncology.

Therapeutic Areas and Indications
Kyowa Hakko Kirin’s product portfolio spans several therapeutic areas, each addressing distinct medical needs. The company’s strategy focuses on four key therapeutic domains:
- Nephrology: Here, innovative drugs such as CRYSVITA® (burosumab-twza) have been introduced for disorders like X-linked hypophosphatemia (XLH) and fibroblast growth factor 23 (FGF23)–related hypophosphatemia, indicating a strong commitment to rare metabolic and renal diseases.
- Oncology: In addition to its supportive care products (e.g., pegfilgrastim and filgrastim) that are instrumental in managing chemotherapy-induced neutropenia, Kyowa Hakko Kirin is exploring novel oncology treatments and expanding its portfolio with products that target hematologic cancers and other malignancies.
- Immunology/Allergy: The company’s research and development efforts in this area extend into the development of monoclonal antibodies targeting immune-mediated disorders, further strengthening its presence in the immunology sector.
