FEMALE
18-75 years
Phase:
PHASE2
Brief Summary
The goal of this phase II single arm prospective clinical study is to evaluate the efficacy and toxicity of RC48 plus carboplatin neoadjuvant therapy in HER2 expressed epithelial ovarian cancer patien...

Exclusion
- \- Tumor-related criteria:

- History of other primary malignancies, except for those with minimal risk of metastasis or death.
- \- Concurrent treatments:
- Previous treatment with Vedicimab or other HER2-targeted therapies.
- Prior anti-cancer treatment for ovarian cancer, including chemotherapy, immunotherapy, or targeted therapy; patients may receive concurrent hormone therapy (e.g., hormone replacement therapy) or bisphosphonates for non-cancer-related conditions.
- \- Other:
- Known hypersensitivity to monoclonal antibody therapy, MMAE class drugs, or any component of the study drug.
- Pregnant or breastfeeding women.
- Investigator believes the subject has other severe systemic diseases or conditions that make participation in the clinical study inappropriate.
