IMMUNO-ONCOLOGY MARKET MARKET OVERVIEW

The global immuno-oncology market size was valued at USD 69.827 billion in 2025 and is expected to reach USD 343.06 billion by 2034, growing at a compound annual growth rate (CAGR) of about 19.35% from 2025 to 2034.

The United States Immuno-Oncology Market size is projected at USD 23.09166 Billion in 2025, the Europe Immuno-Oncology Market size is projected at USD 18.26664 Billion in 2025, and the China Immuno-Oncology Market size is projected at USD 18.81827 Billion in 2025.

A cutting-edge field of study called immuno-oncology aims to support the body's immune system in battling cancer. The immune system may be strengthened or suppressed by drugs used to treat cancer to bolster the body's defences against cancer, infections, and other illnesses. It uses compounds produced by the body or in a lab to strengthen the immune system and aid in the body's search for and elimination of cancer cells. These are drugs that block certain molecules on the surface of cancer cells or immune cells, allowing the immune system to recognize and attack the cancer cells more effectively. 

KEY FINDINGS

COVID-19 IMPACT

 Pandemic Hamper the Demand of Immuno-Oncology to Market Growth

The COVID-19 pandemic has had a significant impact on Immuno-Oncology (IO), both in terms of research and clinical practice. many IO clinical trials have been disrupted or delayed due to the pandemic, as hospitals and clinics shifted their focus and resources to treating COVID-19 patients. This has led to a slowdown in the development of new IO therapies, as well as delays in the approval of existing therapies. 

LATEST TRENDS

Increasing Demand for Immune Checkpoint Inhibitors to Support Market Expansion

These drugs have been very successful in treating certain types of cancer, but they do not work for everyone. Researchers are now exploring ways to combine checkpoint inhibitors with other drugs or therapies to improve their effectiveness. This approach involves modifying a patient's own T cells to recognize and attack cancer cells. Researchers are exploring ways to combine adoptive cell therapy with other IO therapies to enhance their effectiveness.

• According to the American Cancer Society, over 45% of new oncology clinical trials in 2023 involve immuno-oncology agents.

• According to World Health Organization data, the number of countries funding national immunotherapy initiatives rose by 30% between 2020 and 2023.

IMMUNO-ONCOLOGY MARKET MARKET SEGMENTATION

By Type Analysis

According to type, the immuno-oncology market can be segmented into immune checkpoint inhibitors, cytokine-based immunotherapy, cancer vaccines, CAR-T cell therapy and others.

In terms of type, the immune checkpoint inhibitors are anticipated to be the largest segment during the forecast period.  

By Application Analysis

Based on application, the immuno-oncology market can be divided into hospitals, drugstores, and others.

In terms of application, the hospitals market is projected to hold the largest immuno-oncology market share through forecast period. 

DRIVING FACTORS

Success in clinical trials will Boost Market Growth 

IO is the success of IO therapies in clinical trials. IO therapies have shown remarkable results in treating certain types of cancer, including melanoma, lung cancer, and bladder cancer, among others. This success has generated interest and investment in the field, leading to further research and development. 

• According to the U.S. Food & Drug Administration, approvals of immune checkpoint inhibitors increased by 50% from 2019 to 2022.

• According to National Cancer Institute statistics, patient enrollment in CAR-T cell therapy trials grew by 65% over the past five years.

Better Understanding of the Immune System will Fuel Market Growth

Advances in our understanding of the immune system have also contributed to the growth of IO. Researchers now have a better understanding of how the immune system recognizes and attacks cancer cells, and how tumors can evade the immune system. This knowledge has led to the development of new IO therapies that target different aspects of the immune system. IO therapies can be tailored to individual patients based on their specific cancer type and immune profile. This personalized approach has the potential to improve outcomes and reduce side effects.

RESTRAINING FACTORS

Limited Patient Response and Side Effects Will Limit Market Growth

While IO therapies have shown remarkable success in treating certain types of cancer, they do not work for all patients. This limited response rate can be a restraining factor, as it may limit the widespread adoption of IO therapies. IO therapies can cause significant side effects, including autoimmune reactions and inflammation. These side effects can be severe and may limit the use of IO therapies in certain patients. 

• According to National Institutes of Health, only 22% of low-income countries have access to at least one approved immuno-oncology drug.

• According to the European Medicines Agency, treatment-related adverse event rates remain around 18% across all immuno-oncology therapies.
