- 4.Confirmed to be HER2 positive (HER2-positive is defined as IHC 3+ or IHC 2+ with ISH positive) by the pathology department of participating study center.
- 5.Have received treatment regimen including trastuzumab (allowed marketed trastuzumab biosimilars) or inetetamab with radiologic or pathologic progression/ relapse during the advanced stage, during neoadjuvant or adjuvant therapy, or within 12 months after treatment.
- 6.Previously treated with taxanes.
- 7.Had radiologic and/or pathologic progression or intolerance of the latest systemic anti-tumor therapy.

You will not qualify if you...
- 1. Have previously been treated with an anti-HER2 ADC loaded with topoisomerase I inhibitors or medenosin derivative 1 (DM1) or have relapsed after receiving such therapy during or within 12 months after the adjuvant/neo-adjuvant setting or in the advanced stage.
