Shanghai Bao Pharmaceuticals Co., Ltd. (HKG: 2659) has entered a strategic partnership with Shanghai RAAS Blood Products Co., Ltd. (SHE: 002252) to develop novel subcutaneous formulations of blood products utilizing recombinant human hyaluronidase (rHuPH20) technology. The collaboration aims to transform hours-long intravenous infusions into minutes-long subcutaneous injections, addressing critical patient compliance and healthcare efficiency challenges in the $30 billion global blood products market.
Mechanism: rHuPH20 temporarily depolymerizes hyaluronan in subcutaneous tissue, increasing permeability and enabling rapid dispersion and absorption of large-volume biologics and blood products

Patient-Centric Value: Partnership aims to deliver “more convenient and patient-friendly” therapies, addressing quality-of-life deficits in chronic blood product-dependent conditions (primary immunodeficiency, hemophilia, CIDP).
Resource Optimization: Shift from clinic-based IV administration to home-based SC therapy aligns with China’s healthcare cost containment and tertiary hospital decongestion policy priorities.
Forward‑Looking Statements This brief contains forward‑looking statements regarding subcutaneous blood product development timelines, regulatory approval pathways, and commercial potential of rHuPH20-enabled formulations. Actual results may differ due to formulation stability challenges, immunogenicity risks with hyaluronidase, and competitive responses from global blood product leaders (CSL Behring, Takeda, Grifols).-Fineline Info & Tech
