BeOne Medicines Honored with the Global Oncology Innovation Leadership Award at BIOHK 2025, Supporting "1+" to Accelerate the Delivery of Innovative Cancer Therapies

Diverse Pipeline to Drive Global Impact

BeOne's R&D spans both hematologic and solid tumors:

• BTK inhibitor: BeOne’s first independently developed innovative drug, and the only treatment worldwide in its class to have completed head-to-head clinical trials in both Chronic Lymphocytic Leukemia (CLL) and Waldenström’s Macroglobulinemia (WM)¹. It has been approved in more than 75 markets and was honored with the prestigious Prix Galien Suisse in 2023²..
• PD-1 inhibitor (immunotherapy): Approved in Hong Kong for six indications, including non-small cell lung cancer, esophageal cancer, and gastric cancer, with expansion to nasopharyngeal carcinoma and lung cancer — two of the most prevalent cancer types in Asia. This therapy is marketed in 47 countries and regions including the United States, European Union, China, and Japan, with over 60 indication-approval applications submitted to expand its global coverage.

Fast-to-Proof of Concept (PoC) Strategy to Accelerate Innovation Delivery
BeOne's integrated development approach combines robust R&D capabilities, a PoC-driven strategy and a wide portfolio of assets. With over 40 Phase 3-ready or registration-potential clinical trials and more than 40 R&D assets in clinical and commercialization stages, BeOne maintains leadership across multiple technology platforms, including multi-specific antibodies, chimeric degradation activating compounds (CDACs), and antibody-drug conjugates (ADCs).

Through the PoC strategy, BeOne concentrates on highly differentiated and promising molecule candidates. The company has successfully pushed through the clinical development for 20 drug molecules and obtained regulatory approvals across six continents, demonstrating its outstanding R&D efficiency and globalization strategy.

Globalization to Strengthen Sustainable Supply
BeOne has established three major R&D and manufacturing bases in the United States and China, encompassing the entire industry chain from research and development to manufacturing and commercialization. Notably, the Guangzhou campus spans 1.3 million ft² and features advanced manufacturing capabilities to produce large-molecule drugs, serving as a core supply hub in the Greater Bay Area, including Hong Kong. This footprint ensures a stable drug supply and enhances accessibility for patients in the region.

As one of the world's top 20 leading oncology patent holders³ and listed as one of the "World's Top 10 Most Inventive Pharmaceutical Companies"⁴ by IDEA Pharma in 2025, BeOne will continue to devote its efforts to researching hematologic and solid tumors. Leveraging Hong Kong as a strategic bridge between Asia and the international community, BeOne is committed to accelerating the development and delivery of innovative therapies, collaboratively driving a new paradigm for cancer care regionally and globally.

Prof. Albert Yu, Chairman of Hong Kong Biotechnology Organization, remarked, "BeOne's leadership in oncology is fully evident in its innovative drug development, globalization strategy, and significant improvements in quality of life for cancer patients locally and worldwide. Grounded in rigorous scientific research, BeOne aligns clinical needs with accessibility considerations across various markets to launch multiple self-developed innovative medicines to the global stage. The company's efforts represent scientific excellence and a profound commitment to cancer patients, deserving of the Global Oncology Leadership Award."
