Hyaluronic Acid & Hyaluronidase

Hyaluronic Acid (HA), a key component of the extracellular matrix, is a natural glycosaminoglycan with unique water-retaining properties and viscoelasticity. It plays a crucial role in maintaining the structure and function of tissues.

Hyaluronidase (HAase) is a family of enzymes that specifically degrades HA. By hydrolyzing HA molecules, it reduces tissue viscosity and barrier function, thereby reversibly enhancing tissue permeability. This type of enzyme is widely present in nature, and its biological activity holds significant application value in fields such as drug delivery and tissue engineering. Currently, recombinant human hyaluronidases (e.g., rHuPH20) have become the first choice for clinical and scientific research applications due to their high purity and low immunogenicity.

Recombinant Human Hyaluronidase: Ushering in a New Era of Subcutaneous Delivery of Biologics

By specifically degrading the hyaluronic acid matrix in tissues, recombinant human hyaluronidase significantly improves the subcutaneous penetration efficiency of drugs. This mechanism is crucial for solving the delivery challenges of large-molecule biologics (especially monoclonal antibodies) and high-concentration formulations.

Traditionally, large-molecule antibody drugs are limited by their large molecular weight and high viscosity, making them difficult to deliver effectively via subcutaneous injection. They usually rely on time-consuming intravenous infusion. Although high-concentration formulations can reduce the injection volume, their viscosity increases further, which exacerbates the difficulty of subcutaneous injection and patient discomfort. The application of recombinant human hyaluronidase has broken this bottleneck. Currently, a number of recombinant human hyaluronidases and related formulations have been approved for marketing worldwide, including:

· Recombinant human hyaluronidase rHuPH20 from Halozyme Therapeutics;

· Hyqvia from Takeda Pharmaceutical Company (containing 10% active immunoglobulin and recombinant human hyaluronidase);

· Darazalex Faspro (subcutaneous injection of daratumumab [CD38]) from Johnson & Johnson;

· Rituxan Hycela (rituximab) and Herceptin Hylecta (trastuzumab) from Roche.

Overview of Clinical Development Programs for Recombinant Human Hyaluronidase

As of June 2025, the recombinant human hyaluronidase technology platform has been expanded to more than 80 clinical development programs, covering the entire stage from early-phase trials to new drug application (NDA). Among these, approximately 70% are in Phase I/II, 20% have entered Phase III or the marketing stage, and the remaining 10% are already marketed products.

In the future, with the continuous breakthroughs of Chinese enterprises in localized R&D and the collaborative innovation with international high-volume injection technologies, the market prospect of recombinant human hyaluronidase will be even broader. The recombinant human hyaluronidase developed by ImmuneOnco has established a significant differentiated advantage through its high-expression CHO cell platform. It has currently reached a cooperation agreement with Yangtze River Pharmaceutical Group, and is expected to become a key breakthrough in the industrialization of domestic recombinant human hyaluronidase.
