Scientists Discover Antibody That Halts Aggressive Triple-negative Breast Cancer
There are many types of breast cancers. Triple-negative breast cancer (TNBC) is considered one of the most aggressive and difficult to treat. Triple-negative breast cancer grows rapidly and often spreads at an early stage. It also lacks hormone receptors like estrogen receptors (ER), progesterone receptors (PR), and HER2 protein, which are required for treating many other breast cancers with targeted medications. Therefore, it is difficult to treat this cancer with standard hormone therapies. Owing to this, patients are mostly dependent on surgeries, radiations, and chemotherapy for the treatment. It also has a higher risk of recurrence.
Researchers have developed a new antibody. Its purpose is to interfere with the mechanisms that allow TNBC cells to survive, multiply, and also evade detection by the immune system.

O’Quinn, Olivia Sweatt, Mohamed Faisal Kassir, G. Aaron Hobbs, Michael Ostrowski, Ann-Marie Broome, Shikhar Mehrotra and Nancy Klauber-DeMore published their findings under the title “Secreted frizzled-related protein 2 monoclonal antibody-mediated IFN-ϒ reprograms tumor-associated macrophages to suppress triple negative breast cancer” in December 2025.
Potential Benefits
ENTECH STEM Magazine has included this research in its list of the Top 10 Pharmacy Discoveries of 2025.
Improved Treatment Options for Patients
- The targeted antibody could offer a new treatment option for individuals with triple-negative breast cancer. This type of cancer is one of the most aggressive and difficult to treat.
- Access to this targeted therapy can provide patients as well as their families with hope. It can also increase their confidence in the treatment plan. These benefits may positively affect overall well-being and quality of life.
Reduced Burden on Healthcare Systems
- If the targeted antibody proves effective in clinical trials and is ultimately approved for use, it could potentially reduce the overall burden on healthcare systems by providing a more targeted and potentially more cost-effective treatment option for triple-negative breast cancer patients.
- This could lead to decreased hospitalizations, reduced need for extensive and often debilitating treatments, and a lower overall strain on the healthcare infrastructure, ultimately benefiting the broader community.
Enhanced Survival Rates and Reduced Mortality
- By disrupting the multiple survival strategies used by triple-negative breast cancer, this targeted antibody could lead to improved clinical outcomes, including increased survival rates and reduced mortality for those affected by this devastating form of cancer.
- Improved treatment options and better clinical outcomes can have far-reaching implications, therefore, allowing patients to spend more quality time with their loved ones and participate more actively in their daily lives.
Potential Educational and Career Opportunities
Cancer Biology and Molecular Oncology
- Investigating the specific molecular mechanisms and signaling pathways that the targeted antibody disrupts in order to inhibit the survival and proliferation of triple-negative breast cancer cells.
- Studying the genetic, epigenetic, as well as cellular characteristics that contribute to the aggressive and treatment-resistant nature of triple-negative breast cancer
- Exploring the potential for combining the targeted antibody with other treatment modalities, such as chemotherapy or immunotherapy, to enhance the overall anti-cancer efficacy
Biomarker Discovery and Personalized Medicine
- Identifying predictive biomarkers and patient-specific factors that may influence the response to the targeted antibody treatment.
- Researchers are developing companion diagnostic tests. They are also exploring multimodal approaches to identify the patients most likely to benefit from the targeted therapy.
- Integrating the targeted antibody into personalized treatment strategies that consider the unique genetic and molecular profiles of individual patients.
Antibody Engineering and Protein Design
- Advancing the design and engineering of the targeted antibody to optimize its specificity, affinity, and potency against the cancer targets.
- Developing novel antibody formats, conjugation strategies, or delivery systems to improve the antibody’s pharmacokinetics, biodistribution, and tumor penetration.
- Exploring the potential for rational protein design and computational modeling to guide the development of next-generation targeted antibodies.
