Immunotoxin Market Report 2025

This Immunotoxin market report provides a comprehensive analysis of the market’s characteristics, size, and growth, including segmentation, regional and country-level breakdowns, competitive landscape, market shares, trends, and strategies. It also tracks historical and forecasted market growth across various geographies.

The immunotoxin market size has grown strongly in recent years. It will grow from $60.97 billion in 2024 to $66.62 billion in 2025 at a compound annual growth rate (CAGR) of 9.3%. The growth in the historic period can be attributed to the discovery of target antigens, advancements in monoclonal antibody technology, preclinical efficacy studies, clinical trials and regulatory approval, and identification of resistance mechanisms.

The immunotoxin market size is expected to see strong growth in the next few years. It will grow to $93.93 billion in 2029 at a compound annual growth rate (CAGR) of 9%. The growth in the forecast period can be attributed to the increasing incidence of cancer, rising demand for natural and organic products, expansion of the cosmetic industry, expansion of R and D financing, and improving healthcare infrastructure. Major trends in the forecast period include precision medicine approach, enhanced targeting strategies, multifunctional immunotoxins, combination therapies, and advancements in monoclonal antibody technology.

The rising incidence of breast cancer is anticipated to drive the growth of the immunotoxin market. Breast cancer, a type of cancer that develops in breast cells, is becoming more common due to factors such as improved screening, lifestyle changes, and increased life expectancy. Immunotoxins assist in breast cancer treatment by specifically targeting and killing cancer cells while sparing healthy cells, thereby reducing the side effects commonly associated with traditional chemotherapy. For example, according to the American Cancer Society, a US-based non-profit organization, there were 300,590 new cases of breast cancer reported in 2023, an increase from the 290,560 cases reported in 2022. Thus, the rising incidence of breast cancer is fueling the expansion of the immunotoxin market.

Leading companies in the immunotoxin market are concentrating on developing antibody-drug conjugates (ADCs) to improve the precision and effectiveness of cancer treatments. ADCs are biopharmaceuticals designed for targeted cancer therapy, consisting of an antibody linked to a cytotoxic drug, which allows for the targeted delivery of the drug to cancer cells expressing a specific antigen. For instance, in April 2024, Pfizer Inc., a US-based pharmaceutical company, and Genmab A/S, a Denmark-based biotechnology company, received full U.S. Food and Drug Administration (FDA) approval for TIVDAK, an antibody-drug conjugate designed to treat patients with metastatic or recurrent cervical cancer. TIVDAK's toxic payload, monomethyl auristatin E, is a microtubule-disrupting agent that induces cell death. This novel mechanism contributes to its effectiveness in cancer treatment. TIVDAK demonstrated statistically significant improvements in overall survival, making it a promising option for patients with recurrent or metastatic cervical cancer.

In February 2024, AbbVie, a US-based biopharmaceutical company, acquired ImmunoGen, Inc. for an undisclosed amount. Through this acquisition, AbbVie seeks to strengthen its oncology portfolio by incorporating ImmunoGen's cutting-edge antibody-drug conjugate technology, thus advancing the development of targeted cancer therapies. ImmunoGen, Inc. is a biotechnology company specializing in immunotoxins.

Major companies operating in the immunotoxin market are Pfizer Inc., Roche Holding AG, AbbVie Inc., Bayer AG, Bristol Myers Squibb, Thermo Fisher Scientific Inc., AstraZeneca plc, Merck KGaA, BioNTech SE, Ipsen Pharma, Seagen Inc., Orion Corporation, GenScript, Cytek Biosciences, MacroGenics Inc., Sutro Biopharma Inc., Sorrento Therapeutics Inc., Innate Pharma Inc., Cayman Chemical, ImmunoGen Inc., Mersana Therapeutics, Molecular Templates Inc., Celldex Therapeutics, CytImmune Sciences Inc., Enzo Life Sciences Inc.

The countries covered in the immunotoxin market report are Australia, Brazil, China, France, Germany, India, Indonesia, Japan, Russia, South Korea, UK, USA, Canada, Italy, Spain.

Immunotoxins are bioengineered proteins that combine an antibody or antibody fragment with a toxin to specifically target and destroy certain cells, such as cancer cells. The antibody segment of the immunotoxin attaches to a specific antigen on the surface of the target cell, delivering the toxin directly to it. Immunotoxins are crafted to avoid harming healthy cells and tissues, thereby reducing side effects compared to traditional chemotherapy.

The primary types of immunotoxins include anthrax-based toxins, diphtheria toxin (DT) and its derivatives, pseudomonas exotoxin (PE) and its derivatives, ribosome-inactivating protein-based immunotoxins, ribonuclease-based immunotoxins, among others. Anthrax-based toxins are substances produced by the bacteria that cause anthrax, a severe disease. These toxins are used in various applications, including the treatment of solid tumors, leukemias, and more, by different end users such as hospitals and clinics, cancer and radiation therapy centers, research laboratories, and others.
