Summary

This phase 3 trial tests whether adding the drug capecitabine to standard chemotherapy improves outcomes for people with early triple-negative breast cancer. The study involves 325 participants and aims to see if the combination leads to a higher rate of complete tumor disappearance before surgery. Pembrolizumab is also allowed in both treatment groups.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
capecitabine (added to standard chemotherapy drugs epirubicin, cyclophosphamide, paclitaxel, carboplatin, and pembrolizumab)
What this could lead to
If successful, this could lead to a more effective chemotherapy regimen for early triple-negative breast cancer, potentially increasing the chance of a complete response before surgery.
What could go wrong
This is a phase 3 trial, but results are not yet available. Adding capecitabine may increase side effects without improving outcomes, and the study only includes specific patient types.
