Vaccine to prevent breast cancer by targeting tumor proteins

Project 3

NIH-funded research Mayo Clinic Rochester · NIH-11176765

This project is testing a multi-antigen vaccine that trains the immune system to recognize proteins linked to early breast changes to help prevent breast cancer in women at higher risk.

What this research studies

From your point of view, this work pairs a small early human vaccine trial with lab studies of breast tissue and blood to guide vaccine design. Researchers will look at tissue from women with benign breast disease at Mayo Clinic and Karmanos Cancer Center to see which tumor proteins appear before cancer develops. People in the Phase Ib vaccine effort will have blood drawn to measure antibody and T-cell responses to the vaccine. The team will use those tissue and blood findings to refine which antigens to include and identify who may benefit most from a future prevention vaccine.

Who could benefit from this research

Good fit: Ideal candidates are women at elevated risk for breast cancer, such as those with a history of benign breast disease or other risk markers who can attend the participating centers.

Not a fit: People without elevated breast cancer risk, men, or patients whose tumors do not express the targeted antigens are unlikely to benefit from this vaccine approach.

Why it matters

Potential benefit: If successful, the vaccine could reduce future breast cancer risk by teaching the immune system to attack early tumor-related proteins.

How similar studies have performed: Early clinical vaccine trials in breast cancer have shown durable T-cell and antibody responses, but prevention of cancer in large-scale trials has not yet been established.
