- Subjects are older than or equal to 18 years old and younger than or equal to 75 years old on the day of signing the informed consent;
- Histologically or cytologically confirmed, metastatic or locally advanced unresectable HER2-positive solid tumors;
- Prior antitumor therapy needs to meet the following conditions:
Her2-positive GC/GEJ: has not received prior systemic treatment for metastatic or locally advanced unresectable GC/GEJ, or has received prior systemic treatment≥1 line of systemic treatment with disease progression, front-line systemic treatment includes at least platinum or fluorouracil based chemotherapy with or without trastuzumab; Subjects who relapsed within 6 months after the end of neoadjuvant/adjuvant chemotherapy were considered as line 1 treatment failure; Her2-positive BC: prior treatment with ≥1 line of HER2-targeted therapy for metastatic disease and disease progression; Subjects who relapsed within 12 months after the end of neoadjuvant/adjuvant chemotherapy were considered as line 1 treatment failure; Other HER2-positive solid tumors: previous ≥1 line of systemic therapy for metastatic or locally advanced unresectable tumors with disease progression, no clear standard therapy for prolongation of survival, or after subjects rejected 1 line of systemic therapy; Frontline systemic therapy for ovarian and cervical cancer includes at least platinum-based (cisplatin or carboplatin) chemotherapy; Frontline systemic therapy for ESCC and mCRC includes at least platinum combined with fluorouracil or tax-based chemotherapy; MCRC requires ≥2 lines of systemic therapy for metastatic or locally advanced unresectable tumors and disease progression; Subjects who relapsed within 6 months after completion of neoadjuvant/adjuvant platinum-containing chemotherapy Line 1 treatment failure;
