Progression-Free Survival | The time elapsed from the enrollment date to the first occurrence of either tumor progression or death from any cause. | Approximately 1 years after last participant enrollment. |
disease control rate (DCR) | The proportion of subjects with complete response (CR) and partial response (PR) and stable disease(SD) in total subjects | Approximately 1 years after last participant enrollment. |
duration of response (DOR) | The time from the date for first documented response of complete response (CR) or partial response (PR) to the date of first documented of disease progression or death, whichever occurs first. | The time from the start of treatment to the first observation of response (Complete Response [CR] or Partial Response [PR]) that is ultimately confirmed (typically via a subsequent reassessment at least 4 weeks later, per RECIST criteria). |
overall survival (OS) | The time from the starting date of study drug to the date of death due to any cause. | Approximately 1 years after last participant enrollment. |

- Subjects can provide tumor specimens (paraffin blocks, formalin-fixed paraffin-embedded \[FFPE\] sections, or fresh tissue sections) from the primary or metastatic site for HER2 detection, with HER2 immunohistochemistry (IHC) test results of IHC 1+, 2+, or 3+ (previous test results confirmed by the investigator are also acceptable);
- Presence of at least one evaluable lesion (per RECIST 1.1 criteria);
- Expected survival time ≥ 6 months;
- Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) score of 0 to 1;

- Normal function of major organs, meeting the following criteria:
Left ventricular ejection fraction (LVEF) ≥ 50%; Hemoglobin (Hb) ≥ 9 g/dL; Absolute neutrophil count (ANC) ≥ 1.5 × 10⁹/L; Platelets (PLT) ≥ 100 × 10⁹/L; Serum total bilirubin (TBIL) ≤ 1.5 × upper limit of normal (ULN); Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 × ULN in the absence of liver metastasis, and ALT and AST ≤ 5 × ULN in the presence of liver metastasis; Serum creatinine (Scr) ≤ 1.5 × ULN, or creatinine clearance (CrCl) ≥ 40 mL/min calculated by the Cockcroft-Gault formula.
History of malignant tumors other than cervical cancer, except for the following two situations:
