Summary

This phase 2 trial tests whether a vaccine made from a protein found on many triple-negative breast cancer cells can help prevent the cancer from coming back. Participants receive the vaccine along with an immune booster and a low dose of chemotherapy. The study includes women with stage 1-3 triple-negative breast cancer who have already completed standard treatments like surgery and chemotherapy.

Active substance

multi-epitope folate receptor alpha peptide vaccine, sargramostim (GM-CSF), and cyclophosphamide

What this could lead to

If successful, this vaccine approach could help prevent triple-negative breast cancer from coming back after surgery and standard treatments.

What could go wrong

This is a phase 2 trial, so it is still early. The vaccine may not work for everyone, and side effects from the chemotherapy and vaccine are possible.
