Rising Clinical Innovations and Combination Therapies Drive Keytruda Market Growth
The Keytruda market is expanding as immunotherapy shows strong efficacy across cancers such as lung cancer, melanoma, and head and neck cancers. Increasing clinical use and emphasis on combination therapies are key growth drivers, with emerging treatments enhancing outcomes and patient survival. Ongoing investments in late-stage trials, pipeline development, and strategic collaborations are accelerating innovation. Improved healthcare infrastructure and rising patient awareness further reinforce the market’s positive growth outlook.
High Costs and Regulatory Challenges Curb Keytruda Market Expansion
High treatment costs and limited reimbursement restrict access in some regions, while safety concerns related to immune-related adverse effects may limit broader use. Regulatory hurdles and manufacturing complexities can delay approvals and supply. Additionally, patent expirations and the entry of biosimilars are expected to increase competition, affecting pricing and market share. These factors moderate growth despite strong clinical demand for immuno-oncology therapies.
