Triple-Negative Breast Cancer Market Report DelveInsight

DelveInsight’s “Triple-Negative Breast Cancer Market Insight, Epidemiology and Market Forecast – 2035” report delivers comprehensive insights into triple-negative breast cancer, including historical and forecasted epidemiology, current treatment paradigms, and emerging therapies across the 7MM (United States, EU4, United Kingdom, and Japan). The triple-negative breast cancer market size in the 7MM, valued at approximately USD 4.2 billion in the year 2023, is projected to grow substantially at a CAGR of 4.7% during the forecast period (2025-2035). This growth is primarily attributed to the expanding patient pool, enhanced diagnostic modalities, and the introduction of premium-priced targeted therapies addressing specific molecular alterations in triple-negative breast cancer subtypes.

According to DelveInsight’s epidemiological analysis, the total diagnosed incident cases of TNBC in the 7MM exceeded 102K in 2023, with the United States accounting for approximately 44% of these cases. The data indicate that TNBC represents 15-20% of all breast cancer diagnoses, with a higher prevalence observed among women of African and Hispanic descent, premenopausal women, and those with BRCA1 gene mutations. The report segments triple-negative breast cancer patients by age, stage at diagnosis, biomarker expression patterns, and treatment lines, providing valuable insights for strategic market positioning.

The Triple-Negative Breast Cancer Treatment Market Report also provides insights into current TNBC treatment practices, emerging drugs, the market share of individual therapies, and forecasts for emerging drugs in the 7MM from 2020 to 2034.

The current triple-negative breast cancer treatment landscape has evolved significantly in recent years, moving beyond conventional chemotherapy regimens to include targeted approaches. KEYTRUDA by Merck (NYSE: MRK) has established itself as a cornerstone immunotherapy for PD-L1-positive triple-negative breast cancer in combination with chemotherapy, while TALZENNA by Pfizer (NYSE: PFE) has demonstrated efficacy in specific patient subgroups. The approval of antibody-drug conjugates such as TRODELVY by Gilead Sciences (NASDAQ: GILD) has revolutionized treatment for metastatic triple-negative breast cancer, offering improved progression-free survival and manageable safety profiles compared to standard chemotherapy options.

In January 2025, the FDA approved DATROWAY, a promising antibody-drug conjugate developed by AstraZeneca (LON: AZN) and Daiichi Sankyo (TYO: 4568) for previously treated metastatic hormone receptor-positive (HR+), HER2-negative breast cancer, based on the TROPION-Breast01 Phase III trial demonstrating a statistically significant improvement in progression-free survival (PFS) compared to chemotherapy. Additionally, a Phase III global study (TROPION-Breast04) is ongoing, evaluating neoadjuvant DATROWAY combined with durvalumab versus pembrolizumab plus chemotherapy in untreated TNBC and hormone receptor-low/HER2-negative breast cancer, aiming to establish new standards in early-stage treatment.

The triple-negative breast cancer pipeline is robust, with several promising candidates in late-stage development targeting novel pathways and molecular signatures. Adagloxad Simolenin, developed by OBI Pharma, is a therapeutic cancer vaccine targeting Globo H, a tumor-associated glycan antigen. This subcutaneous immunotherapy stimulates antibody production against cancer cells and is currently in Phase III trials for early-stage Globo H+ TNBC.

Another emerging therapy, PADCEV, an ADC targeting Nectin-4 developed by Astellas Pharma (TYO: 4503) and Pfizer (NYSE: PFE), is being studied in Phase II trials for locally advanced or mTNBC. It combines targeted therapy with pembrolizumab to address treatment-resistant cancers. These therapies, among many others, represent a promising future for improving outcomes in TNBC patients.

Recent clinical updates have shaped the evolving TNBC treatment paradigm. In January 2025, results from the KEYNOTE-522 study confirmed the long-term survival benefit of adding KEYTRUDA to neoadjuvant chemotherapy followed by adjuvant KEYTRUDA for early-stage triple-negative breast cancer, with more than 35% reduction in the risk of disease recurrence or death at 5 years.

In April 2025, TRODELVY (developed by Gilead Sciences) in combination with Keytruda (from Merck & Co.) demonstrated positive topline results from their Phase 3 ASCENT-04/KEYNOTE-D19 study. The combination of Trodelvy and Keytruda significantly improved progression-free survival compared to Keytruda alone and chemotherapy in patients with inoperable locally advanced or metastatic triple-negative breast cancer whose tumors express PD-L1.

In January 2025, Mersana Therapeutics announced promising initial clinical data from its Phase 1 trial of emiltatug ledadotin (XMT-1660), an antibody-drug conjugate targeting B7-H4, for patients with advanced or metastatic triple-negative breast cancer and other solid tumors.

Additionally, in December 2024, Lantern Pharma’s investigational drug candidate LP-184 received its second FDA Fast Track Designation specifically for TNBC therapy. This milestone follows LP-184’s previous Fast Track Designation for Glioblastoma earlier in 2024. urrently, LP-184 is undergoing Phase 1A clinical trials to evaluate its safety and tolerability across various solid tumors, including TNBC.

Furthermore, in November 2024, Anixa Biosciences and Cleveland Clinic reported that data from their breast cancer vaccine “continues to exceed our expectations” with plans for a phase 2 study expected to commence in 2025.

Despite these advancements, substantial challenges remain in the triple-negative breast cancer treatment landscape. The molecular heterogeneity of TNBC complicates treatment selection, with at least four distinct molecular subtypes (basal-like, mesenchymal, luminal androgen receptor, and immunomodulatory) requiring different therapeutic strategies. Additionally, acquired resistance to current therapies remains a significant obstacle, necessitating novel combination approaches and sequential treatment strategies to overcome resistance mechanisms. The high cost of innovative treatments also presents access barriers, particularly in emerging markets where triple-negative breast cancer incidence is rising.

Looking ahead, the TNBC market is expected to witness further growth driven by biomarker-guided precision medicine approaches, innovative drug delivery systems, and rational combination regimens. The integration of liquid biopsy technologies for real-time monitoring of treatment response and resistance development is anticipated to optimize treatment sequencing and maximize clinical outcomes. Furthermore, advancements in understanding the tumor microenvironment and immune landscape of TNBC are paving the way for next-generation immunotherapeutic approaches targeting novel immune checkpoints and employing engineered cellular therapies.
