New drug duo aims to shrink breast tumors before surgery

NCT ID NCT07393425

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether a combination of two targeted drugs (trastuzumab deruxtecan and pertuzumab) can shrink or eliminate HER2-positive breast tumors before surgery. About 50 women with stage II-III breast cancer will receive the drugs for three cycles. If the tumor responds well, they continue the same treatment; if not, they switch to a standard chemotherapy regimen. The goal is to see how many patients have no cancer left at the time of surgery.
