Some of the key facts of the HER2 Low Cancers Market Report:

*
As of 2024, the HER2-low cancer market in the United States was valued at approximately USD 1.6 billion, making it the largest among the 7 major markets (7MM), with substantial growth projected through 2034.

*
In April 2025, Allogene's allogeneic dual-targeted CART therapy ALLO329 (CD19/CD70) received FDA Fast Track Designation for refractory HER2-low cancers, including dermatomyositis, necrotizing myopathy, and anti-synthetase syndrome, as well as lupus and scleroderma. The therapy is expected to enter a Phase I RESOLUTION trial by mid2025, with proof-of-concept results anticipated by year-end.

*
Earlier, in January 2025, RESTEM's umbilical cord stem cell therapy RestemL was granted FDA Fast Track status and Orphan Drug Designation for polymyositis and dermatomyositis. Phase I results showed 78% clinical improvement and a 35% reduction in steroid use, with a Phase II/III IIMPACT trial expected in Q1 2025.

*
Among HER2-low cancers in the 7MM, breast cancer accounts for the majority, followed by colorectal cancer, while ovarian cancer represents the fewest cases. The prevalence of breast cancer in older adults is rising, and HER2-low cases now constitute over half of all breast cancer diagnoses.

*
Until 2022, HER2-low patients were generally treated like HER2-negative cases, primarily with chemotherapy or endocrine therapy, especially in HR-negative patients. A significant milestone came in August 2022, when the FDA approved ENHERTU (trastuzumab deruxtecan) for HER2-low breast cancer based on the DESTINY-Breast04 trial, establishing HER2-low as a clinically actionable target and paving the way for earlier-line therapies and additional regulatory approvals.

*
The HER2-low classification is now being explored in multiple solid tumors, including gastric and urothelial cancers, broadening its therapeutic relevance. Leading companies in this evolving space include AstraZeneca and Daiichi Sankyo (DATROWAY), Pfizer (disitamab vedotin), Gilead Sciences (TRODELVY), Duality Biologics and BioNTech (DB-1303/BNT323), Bliss Biopharmaceutical (BB-1701), and Merck and Daiichi Sankyo (ifinatamab deruxtecan).

*
Emerging therapies targeting HER2-low cancers include TROP2-directed ADCs (such as TRODELVY and DATROWAY), bispecific antibodies (e.g., zanidatamab), and immune-based therapies like eftilagimod alpha, notable for its subcutaneous delivery, which allows at-home administration and greater patient convenience.

*
Additionally, Dragonfly Therapeutics' DF1001, a dual NK and T cell engager, is under development for heavily pretreated HER2-low cancer patients, offering a novel immunotherapy approach.

*
In 2024, Japan reported approximately 15,000 cases of HER2-low urothelial carcinoma eligible for targeted treatment. Looking ahead, the HER2-low cancer market is expected to expand significantly, driven by a robust pipeline, personalized therapies, and increasing global cancer incidence.

*
Key companies advancing the HER2-low treatment landscape include Daiichi Sankyo and AstraZeneca, RemeGen and Pfizer (Seagen), Gilead Sciences, Duality Biologics and BioNTech, Immutep, Merck, Bliss Biopharmaceutical (Hangzhou), Zymeworks, Jazz Pharmaceuticals, ALX Oncology, Dragonfly Therapeutics, and others.

*
Promising therapies in development include ENHERTU, DATROWAY (datopotamab deruxtecan), AIDIXI (disitamab vedotin), TRODELVY (sacituzumab govitecan), DB-1303, BNT323 (trastuzumab pamirtecan), Eftilagimod alpha (IMP321), Ifinatamab deruxtecan, BB-1701, ZIIHERA (zanidatamab), among others.

HER2 Low Cancers Overview

HER2 is a transmembrane tyrosine kinase receptor encoded by the ERBB2 gene, playing a key role in regulating cell growth, differentiation, and survival. As a member of the epidermal growth factor receptor (EGFR) family, HER2 status is typically assessed using molecular diagnostics: immunohistochemistry (IHC) to detect protein overexpression and fluorescence in situ hybridization (FISH) to evaluate gene amplification. The HER2-low category refers to tumors with an IHC score of 1+ or 2+ without evidence of gene amplification (FISH-negative or ISH-negative).

HER2/neu primarily signals through the MAPK and PI3K pathways, driving cancer progression when overexpressed or amplified. HER2 expression occurs in multiple cancers, including breast, colorectal, ovarian, endometrial, bladder, gastric, and biliary tract cancers, with breast cancer being the most common.

The emergence of novel antibody-drug conjugates (ADCs) has transformed the treatment of HER2-low tumors, providing meaningful survival advantages. A notable example is ENHERTU, an advanced ADC that links a HER2-targeted monoclonal antibody to a topoisomerase I inhibitor, enabling targeted delivery of cytotoxic therapy to HER2-expressing tumor cells.

HER2 Low Cancers Market Outlook

Treatment approaches for HER2-low cancers, including gastric, endometrial, and other tumor types, are rapidly advancing as emerging research provides deeper insights into HER2's role in these malignancies. Traditional therapies, such as monoclonal antibodies and small-molecule tyrosine kinase inhibitors (TKIs), have demonstrated limited efficacy in breast cancers with low HER2 expression.
