Expansion of hospital-based infusion and reimbursement support is improving access. The market is expected to witness strong and sustained growth across China through 2032.

Introduction

Biosimilar monoclonal antibodies are biologic products that are highly similar to approved reference monoclonal antibodies with no clinically meaningful differences in safety, purity, or potency. These therapies are used extensively in cancer, autoimmune diseases, inflammatory disorders, and ophthalmology. In China, biosimilar monoclonal antibodies are becoming critical tools for improving access to advanced biologic care. Development requires complex manufacturing, analytical comparability, and clinical validation. Regulatory agencies impose stringent requirements to ensure equivalence. As biologic drug spending rises, biosimilar monoclonal antibodies are playing an increasingly central role in sustainable healthcare delivery.

Future Outlook

By 2032, the biosimilar monoclonal antibodies market in China will mature into a highly competitive and volume-driven segment. Multiple biosimilar versions of the same reference products will coexist, intensifying price competition. Broader interchangeability acceptance may further accelerate switching. Expansion into new therapeutic areas beyond oncology and immunology will continue. Local manufacturing and supply chain localization will gain importance. Overall, biosimilar monoclonal antibodies will become standard-of-care alternatives in biologic therapy pathways.
