Improving breast cancer treatment by targeting immune suppression

Targeting myeloid suppression to enhance anti-tumor immunity in breast cancer

['FUNDING_R01'] · UNIVERSITY OF SOUTHERN CALIFORNIA · NIH-10892288

This study is looking at a new way to help breast cancer patients by using a special treatment that combines a medication called entinostat with existing immune therapies to boost the body's immune response against tumors, especially for those with advanced cancer.

What this research studies

This research investigates how to enhance the effectiveness of immune checkpoint inhibitors in breast cancer patients by targeting myeloid immune suppression. The approach focuses on reducing the function of immature myeloid-derived suppressor cells (MDSCs) that hinder the immune response against tumors. By using a combination of a histone deacetylase inhibitor called entinostat with immune checkpoint inhibitors, the research aims to sensitize the tumor microenvironment and improve patient outcomes. The study has shown promising results in preclinical models and early clinical trials, indicating potential benefits for patients with advanced breast cancer.

Who could benefit from this research

Good fit: Ideal candidates for this research are patients with advanced breast cancer who have not responded to standard immune checkpoint inhibitors.

Not a fit: Patients with early-stage breast cancer or those who have not been diagnosed with breast cancer may not receive any benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved treatment responses for breast cancer patients who currently do not benefit from existing immune therapies.

How similar studies have performed: Other research has shown success in targeting myeloid suppression in different cancer types, suggesting that this approach may also be effective in breast cancer.
