Insights into the PD 1 Inhibitor Type Segment
When segmented by type, the PD 1 inhibitor segment is projected to command 42⋅5 share of the market in 2025, reinforcing its leadership position. This dominance has been supported by the well-established mechanism of action of PD 1 inhibitors, which has set the foundation for further development and refinement of therapies targeting refractory cases.
Widespread clinical familiarity and robust safety profiles have contributed to continued reliance on PD 1 based strategies, even in the face of resistance, often as a component of combination regimens. Advances in biomarker identification and dosage optimization have allowed for more precise application of PD 1 inhibitors in refractory populations, extending their utility beyond initial assumptions.
Pharmaceutical pipelines remain heavily concentrated on enhancing the efficacy of PD 1 inhibitors through adjunctive therapies, which has sustained investment and innovation in this segment, securing its leading share of the market.
Segmented by application, lung cancer is expected to hold 38⋅0 share of the checkpoint inhibitor refractory cancer market in 2025, establishing itself as the most significant application segment. This prominence has been reinforced by the high incidence and mortality associated with lung cancer, making it a critical focus area for therapeutic development.
The complex tumor biology and historically poor prognosis in refractory lung cancer cases have driven sustained clinical and commercial attention toward this indication. Enhanced screening programs and improved molecular characterization of lung tumors have enabled more targeted approaches, including refractory-specific interventions.
Additionally, strong engagement from both public and private sectors in funding lung cancer research has facilitated broader access to innovative treatments, fostering adoption of checkpoint inhibitor refractory therapies. The urgency to address unmet needs in this population has propelled lung cancer to the forefront of application areas within the market, consolidating its leadership position.

From 2020 to 2025, sales witnessed significant growth, registering a CAGR of 5.5%.
According to Future Market Insights, a market research and competitive intelligence provider, the Checkpoint Inhibitor Refractory Cancer market was valued at USD 47.9 Billion in 2025.
The key factors leading to the market growth include the geriatric population across the globe, as well as a rapid increase in the global prevalence of several cancers, mainly in emerging and developed economies, which is expected to boost market growth in the forthcoming years.
For instance, as the World Health Organization reports, cancer has become a primary cause of death globally. As per the updated release of Globocan report released by the International Agency for Research on Cancer (IARC), in December 2024, the global burden of cancer has risen to 43 million cases and deaths by cancer have increased to 10 million in 2024. Thus, an upsurge in the volume of the patient pool leads to a greater demand for the market, which is accelerating the growth of the global market during the analysis period.
Leading industry players are focusing on the development and launch of novel PD-1/PD-L1 inhibitors to treat various types of cancers. This escalated the availability of PD-1/PD-L1 immunotherapeutic in the market is expected to boost the checkpoint inhibitor refractory cancer market.
Rise in Incidence of Cancer Globally to Fuel the Market Growth
The rise in the prevalence of cancer around the world is a major factor that will escalate the growth of the global checkpoint inhibitor refractory cancer market in the coming years. For instance, these checkpoint inhibitors are significantly used as front-line treatments for several types of cancer. As per the World Health Organization (WHO), cancer was one of the leading causes of death worldwide, accounting for around ten million deaths in 2024, or nearly one in six deaths. The most common cancers include breast, lung, colon and rectum, and prostate cancers. Thus, there is an increase in demand for checkpoint inhibitors globally.
There are various novel therapies, which have been approved in recent years. In addition, there is a gap between the demand and supply of these therapies, which has led to a huge unmet need. This, in turn, has given vendors an opportunity to conduct studies on drugs such as checkpoint inhibitors. In addition, the increasing approvals of these inhibitors are expected to increase their demand, which is anticipated to fuel the growth of the market.
Increase in Geriatric Population to Accelerate the Market Growth
The rise in cases of the geriatric population globally is projected to fuel the growth of the checkpoint inhibitor refractory cancer market over the analysis period. For instance, as per the Union for International Cancer Control (UICC), the elderly (people aged 65 years and more) are 11 times more likely to develop cancer, when compared to younger people. According to the United Nations, there are over 28.1 million people aged 65 or older, a number that is expected to reach 1.5 billion by 2050. According to the latest estimates and projections from UN DESA’s Population Division, one in six people in the world will be over the age of 65 by 2050, up from 1 in 11 in 2020.
The rise in research and development activities is expected to offer significant lucrative avenues for players in the checkpoint inhibitor refractory cancer market. For instance, market players have been increasingly investing in Research and Development activities, in order to meet the increasing demand. For instance, researchers at Johns Hopkins Kimmel Cancer Center are paving the way in developing novel immunotherapies called anti-PD-1 and anti-PD-L1 for people with advanced melanomas. The aim of the therapy is not to kill cancer cells directly, but to block a pathway, that protects tumor cells from components of the immune system that are capable and ready to fight cancer.
An increase in awareness among people about immune checkpoint inhibitors is projected to provide significant growth prospects for players in the global checkpoint inhibitor market. For instance, with the increase in awareness among people, the demand for these inhibitors is also increasing at a rapid pace globally.
Stringent Government Regulations to Restrain the Market Growth
Globally, several laws have been introduced to monitor the quality as well as the effectiveness of inhibitors. The regulatory requirements are becoming increasingly stringent, as biologics progress through clinical trials and to commercialization. Due to the nature of biologics, which are produced by living cells, the process and the product must be validated as well as strictly monitored against critical quality attributes (CQAs), throughout the manufacturing process, not just at the end as for chemistry-based drugs. This creates hurdles to getting regulatory approval for the biologics, which in turn is expected to impede the growth of the market.
Further, cancer treatment can cause many side effects, such as depression, tiredness, and trouble eating. The National Cancer Institute and the American Cancer Society describe many of these problems and offer tips for preventing or coping with them. Several side effects can happen months or years after treatment. Hence, the risk of complications associated with the treatment is another factor that will hamper the market growth.
High Cost of Inhibitors to Limit the Market Growth
Cancer treatment costs create significant economic challenges for healthcare providers as well as patients, because of the impact they have on patient safety, quality of care, and overall healthcare. The cost of cancer treatment is high, mainly due to laboratory tests, hospitalization, and the administration of novel checkpoint inhibitors (PD-1 and PD-L1) inhibitor therapeutics. The treatment cost of these therapeutics depends on the stage of cancer. In addition, the high cost is leading to a rise in the preference for alternative treatment options such as surgeries.
For instance, on average, the cost of cancer treatment in India is around INR 503,118 (USD 6,300) with a minimum expense of INR 90,561 (USD 1,134) and a maximum cost of INR 27,67,149 (USD 34,650). Also, the cost of available checkpoint inhibitors is high. Thus, the high cost associated with cancer treatment is a major factor that will restrain the treatment adoption rate especially in developing regions.
