According to our (Global Info Research) latest study, the global Inetetamab market size was valued at US$ 154 million in 2025 and is forecast to a readjusted size of US$ 990 million by 2032 with a CAGR of 19.5% during review period.
Inetetamab is a recombinant humanized monoclonal antibody targeting human epidermal growth factor receptor 2 (HER2) and belongs to biologic macromolecular targeted anticancer drugs. It specifically binds to the HER2 receptor on the surface of tumor cells, inhibiting downstream signaling pathway activation, thereby blocking tumor cell proliferation and growth. In addition, it can enhance the immune system’s ability to eliminate tumor cells through antibody-dependent cell-mediated cytotoxicity (ADCC). This drug is mainly used for the treatment of HER2-positive solid tumors such as breast cancer and gastric cancer. It is characterized by strong targeting specificity, proven efficacy, and favorable safety, making it an important monoclonal antibody therapy in the field of HER2-targeted treatments.In 2025, global production of Trastuzumab Rezetecan reached approximately 15,000 vials.
Inetetamab, as a HER2-targeted monoclonal antibody, holds a certain share in the treatment market for HER2-positive tumors such as breast cancer and gastric cancer. With the increasing adoption of HER2 testing and the growing awareness of targeted therapy, the target patient population continues to expand, driving steady growth in market demand. Meanwhile, as a domestically developed humanized antibody, it has advantages in cost control and accessibility, which helps promote penetration in lower-tier healthcare markets. However, market competition is relatively intense, including from the originator trastuzumab and other biosimilars, as well as next-generation ADC drugs such as Disitamab Vedotin and Enhertu, which pose substitution pressure. Overall, the market for Inetetamab represents a “mature and competitive” segment, with future growth mainly driven by pricing advantages, channel expansion, and the development of combination therapy strategies.
