Overview
New York, NY – Feb 19, 2026 – The Global Antibody Therapy Market Size is expected to be worth around US$ 669.1 Billion by 2033, from US$ 231.6 Billion in 2023, growing at a CAGR of 11.2% during the forecast period from 2024 to 2033.
Antibody therapy represents an advanced and targeted approach in modern medicine, designed to enhance the body’s immune response against diseases. Antibodies are specialized proteins naturally produced by the immune system to recognize and neutralize harmful pathogens such as viruses, bacteria, and abnormal cells. In therapeutic applications, monoclonal antibodies are engineered in controlled laboratory environments to specifically bind to selected disease targets.
The basic formation of antibody therapy begins with the identification of a disease-associated antigen, which may include cancer cells, inflammatory markers, or viral proteins. Scientists then isolate immune cells capable of producing antibodies against the selected antigen. Using biotechnology processes such as hybridoma technology or recombinant DNA techniques, identical copies of highly specific antibodies are produced at scale. These antibodies are purified, tested for safety and efficacy, and formulated into injectable or intravenous therapeutic products.
Once administered, therapeutic antibodies function through multiple mechanisms. They may block disease pathways, mark harmful cells for immune destruction, or deliver targeted treatment while minimizing damage to healthy tissues. This precision-based mechanism contributes to improved treatment outcomes and reduced systemic side effects compared with traditional therapies.
Antibody therapy has demonstrated strong clinical potential across oncology, autoimmune disorders, infectious diseases, and rare conditions. Ongoing research and technological advancements continue to expand its applications, supporting the development of next-generation biologics and personalized treatment strategies within the global healthcare landscape.
