Can a daily pill help breast cancer that outsmarts two antibody drugs?
NCT ID NCT07810634
First seen Sep 09, 2026 · Last updated Sep 10, 2026 · Updated 1 time
Summary
Researchers are reviewing medical records to see how well pyrotinib works and how safe it is in people with HER2-positive advanced breast cancer whose disease worsened after treatment with trastuzumab and pertuzumab. The study includes about 200 patients in China who received pyrotinib after those two antibody drugs. The main goal is to measure how long patients live without their cancer getting worse, and researchers also track how many tumors shrink.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- pyrotinib, a daily pill that blocks HER2 signals in cancer cells
- What this could lead to
- If pyrotinib helps this group, it could offer a treatment option for HER2-positive advanced breast cancer that has grown after dual antibody therapy.
- What could go wrong
- This is a small retrospective review of past records, so it cannot prove cause and effect. Results may not apply to all patients, and pyrotinib can cause side effects such as diarrhea and skin reactions.
