These advancements are particularly beneficial in regions with limited access to expert pathologists, supporting the expansion of IHC-based diagnostics in both developed and emerging markets.

Rising Demand for Multiplex Immunohistochemistry

The growing emphasis on multiplex immunohistochemistry (mIHC) is driving innovation in the market, particularly in oncology and immunology research. Unlike traditional single-marker staining techniques, mIHC allows the simultaneous detection of multiple biomarkers in a single tissue sample, providing comprehensive insights into complex disease mechanisms. This approach is gaining traction in cancer research and drug development, where understanding the tumor microenvironment and immune response is critical. For example, Remark et al. developed the multiplexed immunohistochemical consecutive staining on a single slide (MICSSS) technique, which utilizes iterative cycles of tagging, image scanning, and destaining of a chromogenic substrate on a single slide. Pharmaceutical and biotechnology companies are increasingly adopting multiplexing techniques to identify potential therapeutic targets, optimize treatment strategies, and enhance precision medicine applications.

Expansion of Companion Diagnostics in Targeted Therapies

The increasing use of IHC in companion diagnostics is a significant trend shaping the market. Regulatory authorities, including the FDA and EMA, are emphasizing the co-development of diagnostic tests alongside targeted therapies to improve treatment outcomes. IHC-based companion diagnostics are being widely used to identify patient subgroups that are most likely to benefit from specific drugs, particularly in oncology. For instance, the first companion diagnostic to be approved using the FDA's guidance on group claims allowed a single test to be used for a broad group of approved therapies for NSCLC, enabling the treatment of patients with exon19 deletions and L858R mutated EGFR without requiring a specific clinical trial for each test and therapeutic combination. The approval of IHC assays for targeted therapies in breast, lung, and colorectal cancer has accelerated their clinical adoption. As pharmaceutical companies continue to develop personalized treatment options, the demand for companion diagnostic tests using IHC is expected to rise.

Growing Investments in Biomarker Research and Drug Development

The expansion of biomarker research and drug development is contributing to the increasing utilization of IHC in preclinical and clinical studies. Research institutions and pharmaceutical companies are investing heavily in biomarker discovery programs to develop novel diagnostic and therapeutic solutions. IHC is being used extensively in translational research to validate disease-specific markers and assess drug efficacy. For instance, AstraZeneca and Daiichi Sankyo are collaborating to develop and sell Enhertu, an antibody-drug conjugate (ADC) that targets HER2-positive cancers. This collaboration is an example of growing investments in biomarker research and drug development. The rise of immunotherapy and the need for predictive biomarkers in cancer treatment are further driving IHC applications. With increasing collaborations between industry players and academic research centers, the market is expected to witness continuous advancements in biomarker identification and validation, supporting the development of next-generation diagnostic and therapeutic approaches.
