Summary

This is a prospective, multicenter, phase II study designed to evaluate the efficacy and safety of disitamab vedotin combined with platinum plus bevacizumab as first-line therapy for HER2-expressing, HRD-negative high-risk ovarian cancer. Forty-three patients with pathologically confirmed HRD-negative high-risk ovarian cancer will be enrolled. After enrollment, patients will receive disitamab vedotin plus platinum and bevacizumab as first-line and maintenance treatment.

First-line phase:

Carboplatin AUC 5 intravenously on Day 1 every 21 days over 1 h ,Bevacizumab 7.5-15 mg/kg intravenously on Day 1 every 21 days over 30-90 min.

Maintenance phase:

Patients who achieve response (CR or PR) will continue disitamab vedotin monotherapy plus bevacizumab (investigator decides whether to continue disitamab vedotin and for how long).

Maintenance duration: bevacizumab until disease progression or up to 22 cycles; disitamab vedotin up to 6 months (8 cycles).
