Emerging Trends in the HER2-Low Cancers Market

The HER2-low cancers market is on the verge of substantial growth, with a projected annual increase of 9.4% from 2020 to 2034. This rise is primarily attributed to the introduction of innovative treatments, particularly antibody-drug conjugates (ADCs) designed to target cancer cells with low HER2 protein expression. Among these, ENHERTU has become a significant player, revolutionizing treatment approaches for various cancer types, especially breast cancer.

Understanding HER2-Low Cancers

HER2-low cancers are those characterized by a lower expression of the HER2 protein, which does not qualify as HER2-positive cancer. Notably, approximately 63% of breast cancers, 42% of biliary tract cancers, 38% of urothelial carcinomas, and 35% of gastric cancers exhibit HER2-low expression. These cancers present unique challenges, as traditional HER2-targeted therapies have generally been less effective for tumors within this classification.

Market Size and Dynamics

According to DelveInsight, the total market for HER2-low cancers in the seven major markets (7MM: the United States, EU4 nations including Germany, France, Italy, and Spain, the United Kingdom, and Japan) was valued at around USD 3.2 billion in 2024. With increasing recognition and clinical validation of HER2-low cancers, this market is poised to expand significantly. The anticipated rise in target population cases—projected to reach 360,000 by 2034—underlines the growing demand for effective treatment options in this category.

Key Players and Therapies

Several pharmaceutical giants like AstraZeneca, Daiichi Sankyo, and Merck are heavily investing in developing new therapies for HER2-low cancers. Noteworthy is ENHERTU, which stands out for its effectiveness in treating HER2-low breast cancer and is expected to retain the largest market share due to its clinical success and first-mover advantage. Additionally, emerging therapies such as DATROWAY, TRODELVY, and Disitamab vedotin are currently undergoing clinical trials and could contribute significantly to the market.

The current pipeline consists of promising treatments, including:

• - DATROWAY (datopotamab deruxtecan)
• - TRODELVY (sacituzumab govitecan)
• - Ifinatamab deruxtecan (I-DXd)
• - BB-1701
• - Disitamab vedotin

Market Challenges and Future Prospects

Despite the optimistic outlook, the HER2-low cancers market faces several challenges including high therapy costs and varying accessibility across different healthcare systems. However, the continuous advancement in precision medicine, alongside innovative drug development, suggests a positive trajectory. The growing focus on accurate biomarker testing will help ensure that patients receive the appropriate therapies tailored to their molecular profile.

As diagnostics improve, the likelihood of patients benefiting from targeted treatments increases, which in turn enhances the market potential. The competitive landscape continues to evolve, with many companies focused on developing novel agents for HER2-low cancers.

Conclusion

The HER2-low cancer treatment market is undergoing a transformative phase spurred by the introduction of several innovative therapies. As these drugs move through their clinical development and receive regulatory approval, they are expected to redefine treatment standards, ultimately providing new hope for patients diagnosed with HER2-low cancers. The emphasis on targeted therapies represents a significant shift in oncology, fostering an era of personalized medicine that could optimize outcomes for many patients.
