Can a Two-Drug chemo combo shrink BRCA breast tumors before surgery?
NCT ID NCT07821229
First seen Sep 15, 2026 · Last updated Sep 16, 2026 · Updated 1 time
Summary
Researchers test whether giving mitomycin plus carboplatin before surgery helps people with BRCA1 or BRCA2 mutations and locally advanced triple-negative breast cancer. The trial compares this combination, followed by paclitaxel, against standard chemotherapy. About 30 adults with newly diagnosed disease join, and doctors measure how much tumor remains in the breast and lymph nodes after surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a chemotherapy combination of mitomycin and carboplatin
- What this could lead to
- If it works, this could give people with BRCA-linked triple-negative breast cancer a chemotherapy option that shrinks tumors more effectively before surgery.
- What could go wrong
- This is a small early study of 30 people, so results may not hold in larger groups. Chemotherapy can cause side effects, and the combination may not outperform standard treatment.
