Global PD-1 and PD-L1 Inhibitors Market Report and Forecast 2025-2034

PD-1 and PD-L1 Inhibitors Market Overview

PD-1 and PD-L1 inhibitors are checkpoint inhibitors used to block the activity of PD-1 and PDL1 immune checkpoint proteins, commonly present on the surface of cells. These inhibitors play a pivotal role in offering immunotherapy to cancer patients. The interaction of these cell surface proteins is also engaged in the immune system suppression and occurs following infection to restrain the killing of bystander host cells and avoid autoimmune disease.

PD-1 and PD-L1 Inhibitors Market Growth Drivers

Rising Adoption of Immunotherapies and Regulatory Approvals to Drive Market Growth

The increasing prevalence of non-small cell lung cancer (NSCLC) and the growing emphasis on early-stage cancer treatment are key drivers of the market. For instance, in August  2024, results from the AEGEAN Phase III trial showed that an Imfinzi (durvalumab)-based regimen reduced the risk of recurrence, progression, or death by 32% compared to neoadjuvant chemotherapy alone. Following these findings, the U.S. FDA approved Imfinzi in combination with chemotherapy for adult patients with resectable early-stage (IIA-IIIB) NSCLC without EGFR mutations or ALK rearrangements. This approval is expected to strengthen market growth by expanding the use of PD-L1 inhibitors in early-stage cancer management, increasing demand for immunotherapies, and encouraging further research into combination regimens that improve patient outcomes.

Expanding Treatment Options to Impact PD-1 and PD-L1 Inhibitors Market Value 

The demand for effective therapies in metastatic cancers and the expansion of immunotherapy indications are significant market growth drivers. For instance, in March  2024, BeiGene, Ltd. announced that the U.S. FDA had approved TEVIMBRA (tislelizumab-jsgr) as a monotherapy for adult patients with unresectable or metastatic esophageal squamous cell carcinoma (ESCC) who had previously undergone systemic chemotherapy without a PD-(L)1 inhibitor. TEVIMBRA is set to launch in the U.S. in the second half of 2024, expanding treatment options for ESCC patients. This approval is expected to boost the PD-1 and PD-L1 inhibitors market by increasing accessibility to immunotherapies, driving competitive advancements, and encouraging pharmaceutical companies to invest in developing novel PD-1 and PD-L1 inhibitors across multiple oncology indications.

PD-1 and PD-L1 Inhibitors Market Share

PD-1 Inhibitors to Dominate the Segmentation by Type

PD-1 inhibitors are expected to hold the largest market share due to their widespread adoption across multiple cancer types and superior clinical efficacy. Leading drugs such as KEYTRUDA and Opdivo have demonstrated strong survival benefits, driving their demand. The increasing approvals of PD-1 inhibitors for new indications and their combination with emerging immunotherapies further strengthen their dominance. With ongoing clinical trials and expanding patient accessibility, the segment is set to propel market growth, supported by rising cancer incidence and advancements in personalised medicine during the forecast period.

Non-Small Cell Lung Cancer to Lead the PD-1 and PD-L1 Inhibitors Market Segmentation by Application

Non-small cell lung cancer (NSCLC) is poised to dominate the market due to the high global prevalence of lung cancer and the significant clinical success of PD-1 and PD-L1 inhibitors in this indication. According to Expert Market Research , the small cell lung cancer (SCLC) market is anticipated to grow at a CAGR of 8.3% during the forecast period of 2025-2034. Drugs like Imfinzi, KEYTRUDA, and Opdivo have become standard treatments for NSCLC, supported by robust clinical trials and regulatory approvals. Increasing adoption of immunotherapy in first-line treatment and advancements in biomarker-driven therapies will further drive market growth. With expanding research into combination therapies, the NSCLC segment is expected to contribute significantly to market expansion in the forecast period.

Hospital Pharmacies to Hold a Substantial PD-1 and PD-L1 Inhibitors Market Value for Segmentation by Distribution Channel

Hospital pharmacies are expected to maintain the largest market share due to the high administration of PD-1 and PD-L1 inhibitors in clinical settings. These immunotherapies are primarily used for cancer treatment, necessitating hospital-based infusion facilities. The growing number of oncology treatment centres and increasing hospital-based immunotherapy adoption further support this segment’s dominance. Additionally, streamlined distribution networks, hospital collaborations with pharmaceutical companies, and improved patient access to advanced therapies will continue to drive market growth. With the rising burden of cancer, hospital pharmacies are set to remain the primary distribution channel for PD-1 and PD-L1 inhibitors.
