Triple Negative Breast Cancer Overview

Triple Negative Breast Cancer (TNBC) is an aggressive subtype of breast cancer characterized by the absence of estrogen receptors (ER), progesterone receptors (PR), and HER2 protein expression. Because it lacks these common therapeutic targets, TNBC does not respond to hormone therapy or HER2-targeted treatments, making it more challenging to treat compared to other breast cancer types. It accounts for approximately 10-15% of all breast cancer cases and is more commonly seen in younger women, particularly those of African or Hispanic descent, as well as individuals with BRCA1 mutations. TNBC tends to grow and spread faster, often resulting in higher recurrence rates, especially within the first three to five years after diagnosis. Standard treatment primarily involves chemotherapy, surgery, and radiation, though newer approaches like immunotherapy, antibody-drug conjugates, and PARP inhibitors are improving outcomes. Despite advancements, the lack of curative therapies underscores the need for more personalized and durable treatment options.

Triple Negative Breast Cancer Market Outlook

In 2023, the US dominated the TNBC market with USD 2.9 billion (69% share), followed by EU4 and the UK (USD 1.1 billion) and Japan (USD 170 million). KEYTRUDA plus chemotherapy generated the highest treatment revenue across the 7MM.

Triple Negative Breast Cancer (TNBC) lacks hormone receptors and HER2 expression, making it unresponsive to hormonal or HER2-targeted therapies. As a result, chemotherapy remains the primary treatment, particularly for metastatic cases. The treatment sequence typically progresses from neoadjuvant or adjuvant therapy for early stages to first- and second-line options for advanced disease. Immunotherapy, especially PD-1/PD-L1 inhibitors like KEYTRUDA and TECENTRIQ (outside the US), is increasingly used in PD-L1-positive patients.

For early-stage and metastatic TNBC, KEYTRUDA combined with chemotherapy is now a standard, while BRCA-mutated cases benefit from PARP inhibitors such as LYNPARZA and TALZENNA. ADCs like TRODELVY provide additional options for refractory disease. Despite these advances, TNBC remains aggressive, underscoring the need for novel therapies. Promising pipeline candidates include DATROWAY, Adagloxad Simolenin, PADCEV, BNT327/PM8002, and Tilarginine.

Triple Negative Breast Cancer Epidemiology

In 2023, breast cancer incident cases across the 7 major markets (7MM) totaled approximately 680,000. The United States recorded the highest number of Triple Negative Breast Cancer (TNBC) cases at around 45,000, with a projected annual growth rate of 1% through 2034. Within the EU4 and the UK, Germany led with about 11,000 TNBC cases, followed by France at 10,000 and Spain at 5,000.

Japan showed the highest occurrence in Stage II TNBC (6,000 cases), with additional cases across Stage I (3,000), Stage III (4,000), and Stage IV (700). BRCA1-mutated TNBC was the most prevalent gene mutation subtype in EU4 and the UK, accounting for roughly 3,800 cases.

Age-wise, France reported the highest burden among individuals under 45 (3,200 cases). In Italy, Stage II TNBC also dominated with 4,000 cases. Germany's treatment distribution in 2023 included 8,000 cases in neoadjuvant/adjuvant settings and progressively fewer in later lines of therapy, with all segments expected to rise by 2034.

Triple Negative Breast Cancer Drugs Uptake

DATROWAY (Datopotamab Deruxtecan) - AstraZeneca/Daiichi Sankyo

DATROWAY is an investigational antibody-drug conjugate (ADC) for TNBC, being tested as monotherapy and with IMFINZI across neoadjuvant, adjuvant, and metastatic settings. Phase III trials, including a combination with durvalumab launched in December 2023, aim to provide data by 2026 to advance TNBC treatment.

Adagloxad Simolenin - OBI Pharma

This therapeutic cancer vaccine targets the tumor-associated Globo H antigen, stimulating immune responses against cancer cells. Licensed from Merck, Phase III trials in high-risk, early-stage TNBC have shown safety and promising immune activity, with a positive DSMB review in January 2024 supporting continuation.

PADCEV (Enfortumab vedotin) - Astellas/Pfizer

PADCEV is an ADC that targets Nectin-4 on tumors and delivers a cytotoxic payload (MMAE). Administered intravenously, it induces cancer cell apoptosis. Currently in Phase II, it is being tested with pembrolizumab for locally advanced or metastatic TNBC and other solid tumors, offering options for treatment-resistant cases.
