The global immunotherapy drugs market size was estimated at USD 285.73 billion in 2025 and is expected to reach USD 675.98 billion by 2033, growing at a CAGR of 11.41% from 2026 to 2033. This market is primarily driven by the rising incidence of chronic diseases globally.
This market was driven by the rising global burden of cancer and chronic diseases, including autoimmune and inflammatory disorders, alongside the growing limitations of conventional treatments such as chemotherapy and radiation therapy. These constraints had accelerated the shift toward immunotherapy because of its targeted mechanism of action and improved patient outcomes. For instance, February 2025, the World Health Organization reported that cancer was responsible for nearly 10 million deaths in 2020, accounting for almost one in six deaths globally. Breast cancer recorded 2.26 million cases, lung cancer 2.21 million, and colorectal cancer 1.93 million, while lung cancer caused 1.80 million deaths. The organization also estimated around 400,000 childhood cancer cases annually and noted that 30 percent of cancers in low and lower middle income countries were infection related, reinforcing demand for advanced immunotherapies.
Technological advancements and robust research activity play a critical role in driving the immunotherapy drugs market forward. Significant progress in immuno-oncology, particularly in immune checkpoint inhibitors, monoclonal antibodies, and cell-based therapies such as CAR-T, has transformed cancer treatment paradigms. These therapies have demonstrated strong efficacy across multiple solid tumors and hematological malignancies, leading to expanding clinical indications. Pharmaceutical and biotechnology companies are investing heavily in research and development to improve therapeutic effectiveness, reduce adverse effects, and develop next-generation immunotherapies. Strategic collaborations, mergers, and acquisitions are also accelerating innovation and pipeline expansion. Moreover, favorable regulatory frameworks, fast-track approvals, and orphan drug designations in major markets are enabling faster commercialization of novel immunotherapy drugs, thereby contributing significantly to market growth.
Beyond oncology, the immunotherapy drugs market was supported by expanding applications and improving healthcare infrastructure worldwide, which broadened overall market potential. Immunotherapies were increasingly explored for autoimmune diseases, infectious diseases, and rare genetic disorders, enabling wider clinical adoption. In developed regions, strong reimbursement systems, higher healthcare spending, and access to advanced diagnostic facilities facilitated routine use of immunotherapy drugs. At the same time, emerging economies experienced steady growth due to improvements in healthcare systems, rising medical tourism, and government initiatives aimed at strengthening cancer care delivery. Growing awareness among patients and healthcare providers, coupled with gradual improvements in the affordability of biologic therapies, further supported uptake. Together, these interconnected factors sustained long term growth prospects and continued innovation in the global immunotherapy drugs market.
