The growth of the market is supported by their proven clinical effectiveness across a wide range of cancers and their increasing adoption as a standard of care in oncology. With an increasing volume of cancer cases being diagnosed, the demand for effective therapeutics, such as immune checkpoint inhibitors, is rising.
As per the Lancet, there has been a rapid rise in the global burden of cancer between 1990 and 2023, despite significant advances in cancer therapies and sustained efforts to reduce risk factors. Without urgent action and targeted funding, an estimated 30.5 million people are projected to receive a new cancer diagnosis and 18.6 million are expected to die from cancer by 2050, with more than half of new cases and nearly two-thirds of deaths occurring in low- and middle-income countries (LMICs). This escalating disease burden strongly underscores the growing demand for effective and innovative treatments such as immune checkpoint inhibitors.
Immune checkpoint inhibitors (ICIs) are cancer treatment drugs that belong to the class of immunotherapy drugs, which help to enhance the immune system of the body in fighting the tumor cells. These therapies function by inhibiting the action of the immune checkpoint proteins such as PD-1, PD-L1, and CTLA-4, which are used by cancer cells to evade the immune system. By inhibiting these proteins, immune checkpoint inhibitors help to restore the function of T-cells and allow the immune system to better target and eliminate cancer cells. Key players driving the growth of the immune checkpoint inhibitors market include Merck, Bristol-Myers Squibb, Roche, AstraZeneca, and Pfizer, among others. These firms are contributing to the growth of the market through innovation and development of new immunotherapies, expanding the use of existing products, partnerships, and licensing agreements, as well as investments in manufacturing and distribution capacity.
Between 2022 and 2024, the global market witnessed considerable growth to reach USD 56.4 billion in 2024 from USD 41.3 billion in 2022. This expansion was largely driven by the increasing global incidence of cancer, the ability to diagnose and test for biomarkers, and the growing awareness of clinical practitioners to identify patients earlier for immunotherapy. Moreover, the increasing use of immune checkpoint inhibitors as a standard of care for various types of cancers, along with the expansion of their use in combination therapies, has also contributed to the growth of the market.
