Market Transformation for HER2-Low Cancer Therapies Ahead
Significant Growth on the Horizon for HER2-Low Cancer Market
The landscape of the HER2-low cancer treatment market is undergoing a significant evolution, promising transformative outcomes for numerous patients. The key drivers of this change are the recent approvals of innovative therapies such as ENHERTU, DATROWAY, TRODELVY, and others. These advanced antibody-drug conjugates (ADCs) are designed to specifically target HER2-low-expressing cancer cells, especially in breast cancer, which is witnessing major advancements in treatment.
Understanding HER2-Low Cancers
HER2-low cancer refers to tumors that exhibit low levels of the HER2 protein, which means they do not qualify for the HER2-positive designation. This classification is crucial as the prevalence of HER2-low expression varies across different types of cancer. For instance, studies indicate that approximately 63% of breast cancers, 42% of biliary tract cancers, and significant percentages of urothelial and gastric cancers fall under this category.
Current Market Dynamics and Forecast
DelveInsight's analysis suggests that in 2024, the HER2-low cancers market within the seven major markets (7MM) reached a valuation of around USD 3.2 billion, with expectations for continued growth throughout the forecast period of 2025 to 2034. A substantial factor in this growth is attributed to the increasing utilization of ENHERTU, which has shown exceptional clinical efficacy and safety.
Revenue Drivers for 2034
By 2034, breast and gastric cancers are projected to yield the highest revenue among target indications due to extensive clinical development and therapy approvals. ENHERTU is expected to dominate the market share primarily due to its established efficacy as a first-line treatment option.
Challenges and Opportunities in HER2-Low Cancer Treatment
Despite the promising outlook, the HER2-low cancer market faces hurdles. Currently, there are no HER2-targeting therapies available for first-line treatment; existing options focus on relapsed or refractory cases. This gap presents a unique opportunity for pharmaceutical companies to innovate and create tailored therapies for this unique cancer subset.
Market Influencers: Companies to Watch
A range of leading companies such as AstraZeneca, Daiichi Sankyo, RemeGen, and Gilead Sciences are actively developing novel HER2-low cancer therapies that are set to enter the market in the forthcoming years. Their innovative approaches and commitment to addressing unmet needs in HER2-low cancers are essential for overcoming existing barriers.
Pipeline Developments for HER2-Low Cancers
Current clinical funnels reveal several exciting pipeline assets, including therapies like DATROWAY, AIDIXI, and TRODELVY, which are positioned as potential game-changers in the HER2-low cancer treatment space. For instance, ENHERTU's capacity to show effective results in patients previously resistant to traditional treatment regimens has started to reshape market expectations.
Key Industry Developments
Significant movements within the industry include the January 2025 FDA approval of ENHERTU, and the granting of breakthrough designation to additional therapies such as emiltatug ledadotin for patients with advanced or metastatic HER2-low cancers. These milestones underscore the growing recognition of HER2-low as a distinct category within oncology.
The Future of HER2-Low Cancers Market
The future for HER2-low cancer treatments looks bright, with increasing investments pouring into research and development aimed at expanding treatment modalities. As these innovative therapies gain approval and enter clinical practice, they promise to deliver new standards of care, consequently enhancing patient outcomes.
