Neoadjuvant Trastuzumab Deruxtecan (SHR-A1811) + Pertuzumab in HER2+ Breast Cancer
Is NCT07393425 recruiting? Yes, currently enrolling (May 2026). This Phase 2 trial studies multiple treatments for her2 + breast cancer.
Treatment: Trastuzumab Deruxtecan · Pertuzumab · Taxane Chemotherapy · Trastuzumab (or biosimilar) · Pyrotinib 320mg — Patients with Stage II-III HER2-positive breast cancer will receive three cycles of treatment with Trastuzumab Deruxtecan (SHR-A1811) + Pertuzumab, followed by imaging assessment. If clinical complete response (cCR) or radiological complete response/near radiological complete response (rCR/near rCR) is achieved, they will continue to receive an additional three cycles of treatment with Trastuzumab Deruxtecan (SHR-A1811) + Pertuzumab, followed by surgery. If cCR/rCR or near rCR is not achieved, the treatment will be switched to the THPy regimen (paclitaxel-based regimen + Trastuzumab + Pyrotinib) for three cycles.
