WuXi Biologics and HanchorBio Enter Strategic Partnership to Advance Next-Generation Bi- and Multi-Functional Fusion Protein Pipeline

SHANGHAI, Jan. 26, 2026 /PRNewswire/ -- WuXi Biologics (2269.HK), a global leading Contract Research, Development and Manufacturing Organization (CRDMO), and HanchorBio Inc. (TPEx: 7827), a global clinical-stage biotechnology company advancing next-generation immunotherapies for oncology and autoimmune diseases, jointly announced today the signing of a strategic collaboration agreement on the development and manufacturing of multiple next-generation bi-/multi-functional fusion programs from HanchorBio's pipeline.

Under the agreement, WuXi Biologics will provide integrated, end-to-end biologics development and manufacturing services, including cell line development, process and bioassay development, drug product formulation development, and GMP manufacturing. The collaboration is designed to enhance CMC execution efficiency, accelerate clinical translation, and support scalable global development and manufacturing of HanchorBio's innovative fusion protein portfolio derived from its Fc-Based Designer Biologics (FBDB™) platform.

This partnership reflects HanchorBio's strategy to advance its platform-derived, multi-asset pipelines with development speed, manufacturing robustness, and capital efficiency from early clinical stages through commercialization. By leveraging WuXi Biologics' proven capabilities in complex biologics and its global quality systems, HanchorBio aims to shorten development timelines and maintain flexibility across multiple clinical programs.

WuXi Biologics brings extensive experience in complex modalities, including bispecific and multi-specific antibodies, antibody-drug conjugates (ADCs), and fusion proteins. As of 2025, there are 945 projects on WuXi Biologics' integrated platform, with approximately 60% are bi- and multi-specific antibodies, ADCs and fusion proteins, underscoring its track record in enabling accelerated development and manufacturing of advanced therapeutic modalities. Its proprietary technology platforms, such as WuXia™ TrueSite - targeted integration (TI)-based CHO cell line platform, and WuXiHigh^TM - high-throughput formulation development platform, are designed to enhance speed, quality, and scalability.

For HanchorBio, the collaboration supports continued expansion of its proprietary FBDB™ technology platform, which enables the rational design of multi-functional fusion proteins intended to modulate both innate and adaptive immunity. The partnership represents a significant step in aligning discovery innovation with industrial-scale and globally compliant execution as HanchorBio advances its oncology and autoimmune pipelines toward global clinical development.

Dr. Chris Chen, Chief Executive Officer of WuXi Biologics, said: " We are excited to embark on this collaboration with HanchorBio, which underscores the strong trust they placed in WuXi Biologics' comprehensive, end-to-end capabilities for developing next-generation biologics, especially complex molecules. By leveraging our industry-leading technology platforms, proven expertise, and unwavering commitment to quality, we strive to accelerate the development of HanchorBio's innovative bi-/multi-fusion proteins and help bring transformative therapies to patients worldwide."

Dr. Scott Liu, Founder, Chairman, and Chief Executive Officer of HanchorBio, commented: "This partnership with WuXi Biologics strengthens our ability to translate platform-driven innovation into high-quality clinical and commercial assets. As we advance multiple next-generation fusion protein programs, execution speed, manufacturing reliability, and scalability are critical. WuXi Biologics' proven expertise in complex biologics and global development makes them a strong strategic partner as we build a differentiated, multi-asset immunotherapy pipeline."
