First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study tests whether adding the drug pyrotinib to standard trastuzumab therapy can lower the risk of cancer coming back in women with HER2-positive breast cancer who still have cancer cells after initial treatment. About 316 women will take pyrotinib daily for a year. Researchers will track how long participants stay cancer-free and monitor side effects.

What this could mean

Active substance

pyrotinib (a targeted cancer drug taken as a pill once daily for one year, combined with trastuzumab)

What this could lead to

If successful, this could offer a new option to lower the chance of breast cancer returning in patients who still have cancer cells after initial chemotherapy and targeted therapy.

What could go wrong

This is a phase 3 trial, but it is still recruiting and results are not yet known. The drug may cause side effects, and it is unclear if it will be more effective than current standard care.
